Tags Share this article 6/30/15 Published A Decoy Network The strategy behind Sun Tzu’s ‘Art of War’ has been used by the military, sports teams, and pretty much anyone looking for a strategic edge against their foes. As Sun Tzu says “All warfare is based on deception. Hence, when we are able to attack, we must seem unable; when using our forces, we must appear inactive; when we are near, we must make the enemy believe we are far away; when far away, we must make him believe we are near.” Sun Tzu understood that to gain an advantage on your opponent you need to catch him off guard, make him believe you’re something you’re not, so that you can leverage this opportunity to your advantage. As security practitioners we should all supplement our security practices with this timed and tested decoy technique against cyber attackers. There are a few technologies that can be used as decoys, and two of the most common are honeypots and false decoy accounts: A honeypot is a specially designed piece of software that mimics another system, normally with vulnerable services that aren’t really vulnerable, in order to attract the attention of an attacker as they’re sneaking through your network. Decoy accounts are created in order to check if someone is attempting to log into them. When an attempt is made security experts can then investigate the attackers’ techniques and strategies, without being detected or any data being compromised. Design the right decoy But before actually setting up either of these two techniques you first need to think about how to design the decoy in a way that will be believable. These decoy systems shouldn’t be overtly obvious, yet they need to entice the hacker so that he can’t pass up the opportunity. So think like an attacker: What would an attacker do first when gaining access to a network? How would he exploit a system? Will they install malware? Will they perform a recon scan looking for pivot points? Figuring out what your opponent will do once they’ve gained access to your network is the key to building attractive decoy systems and effective preventive measures. Place it in plain sight You also need to figure out the right place for your decoys. You want to install decoys into your network around areas of high value, as well as systems that are not properly monitored with other security technologies. They should be hiding in plain sight and mimicking the systems or accounts that they’re living next to. This means running similar services, have hostnames that fall in line with your syntax, running on the same operating systems (one exception is decoys running a few exploitable services to entice the attacker). The goes the same for accounts that you’ve seeded in applications or authentication services. We decided that in addition to family photos, it was time to focus on couples photoshoot ! Last fall we aired our popular City Photoshoot Tips & Ideas and as a result, gave you TONS of ideas and inspiration. And last but not least, you need to find a way to discretely publicize your applications or accounts in order to attract the attacker. Then, when an attacker tries to log in to the decoy applications or accounts (which should be disabled) you should immediately and automatically start tracking and investigating the attack path. Watch and learn Another important point to make is that once a breach attempt has been made you shouldn’t immediately cut off the account. You might want to watch the hacker for a period of time to see what else that he might access on the network. Many times tracking their actions over a period of time will give you a lot more actionable information that will ultimately help you create a far more secure perimeter. Think of it as a plainclothes police officer following a known criminal. Many times the police will follow a criminal to see if he will lead them toward more information about their activities before making an arrest. Use the same techniques. If an attacker trips over a few of carefully laid traps, it’s possible that he’s just starting to poke around your network. It’s up to you, while you have the upper hand, to determine if you start remediation or continue to guide them under your watchful eye.

The hybrid conundrum: Security beyond the divide The debate over a cloud-only versus hybrid deployment churns with vigor. It’s not merely a technical decision; it’s an embodiment of an organization’s security philosophy. Retaining an on-premises presence offers a sense of comfort, an insurance policy for vital intellectual property. To navigate the hybrid landscape successfully, a unified security approach is imperative. A single-pane view that seamlessly spans visibility, risk assessment, compliance, and intelligent policy automation is the rudder that guides this ship. Blueprint for secure migration In the digital world, where data and applications surge like currents, migrating to the cloud demands meticulous planning and a steadfast commitment to security. Application Dependency: The heartbeat of cloud migration As applications metamorphose, they weave intricate relationships with their ecosystem. Moving them recklessly can disrupt the very heartbeat of your organization. Consider AlgoSec’s partnerships with Cisco Secure Workload, Illumio, and Guardicore. Through this synergy, applications are mapped, relationships dissected, and policies laid bare. These insights power intelligent remediation, ensuring that policies serve the application, not risk its integrity. The goldilocks move: Finding the right application components When migrating applications, precision is paramount. Moving the right components in tandem is akin to choreographing a symphony. Avoiding ‘hair-pinning’ between cloud and on-premises domains is key to preserving user experience and mitigating egress traffic costs. The mantra: migrate high-dependent application tiers in harmonious unison. Purifying the legacy: Pruning unneeded policies Before the embacing the cloud, make sure to clean your digital canvas. Rid it of unneeded policies, unburden the legacy baggage, and craft a secure foundation. AlgoSec advocates a risk-mitigation approach. Tune, optimize, and refine policies. This digital spring-cleaning ensures that your cloud journey is unmarred by relics of the past. The promise of a secure sky As the digital horizon stretches ever farther, cloud security ascends as both a challenge and an opportunity. With each step we take towards a cloud-powered future, we must arm ourselves with knowledge, tools, and practices that will safeguard our data, applications, and innovations. So, the question of how to mitigate risk becomes not just a query, but a clarion call. A call to weave security into the very fabric of our cloud endeavors. A call to adopt the best practices, to forge ahead with a robust strategy, and to ensure that the cloud’s promise of a brighter future is matched only by its commitment to security.

What is endpoint security and its functionality? Endpoint security tools protect individual devices like desktop workstations, laptop computers, and mobile phones from cyber attacks. This usually means installing an endpoint security client on the device which regularly scans for malware and inspects user behaviors to detect signs of unauthorized access. Mobile devices are particularly important to endpoint security because they can change location or get lost or stolen. Many advanced endpoint security tools offer additional features to detect malicious insiders who may have gained access to a legitimate user’s mobile device. What are firewalls in network security? Firewalls are devices that inspect network traffic. They typically sit at the edge of the network, protecting internal network assets from receiving malicious content from outside the network. Traditional firewalls look for packet and port data that indicates unauthorized activity and filter out connections that don’t appear legitimate. Next-generation firewalls offer a much wider range of capabilities to security teams. They can conduct deep packet inspection and identify traffic that belongs to particular apps or users. Some NGFW devices can even detect when sensitive data is being sent out of the network and block the attempt. What is Network Access Control (NAC)? Network access control solutions provide visibility into the actions users take on a network. They enable security teams to enforce access management policies on devices throughout the network. Without an NAC solution in place, security tools would have a much harder time recognizing users and devices based on their usage profiles, or managing permissions and authentication policies without using a separate access control solution. What is Zero Trust Network Access (ZTNA)? Zero Trust Network Access provides secure remote access to the data, applications, and service hosted on a network. It does this through a set of strictly defined access control policies that do not extend trust to users based on their previous behaviors. With a ZTNA policy in place, a malicious user who impersonates an employee and gains access to one segment of the network would not necessarily be able to move onto another segment of the network. How does Zero Trust secure cloud environments within enterprise networks? Cloud-enabled network infrastructure provides a more complex security profile than simple on-premises infrastructure. This is because the organization may not control the entire network, and it may not be able to establish boundaries for that network on its own. Security leaders need to deploy a more complex set of firewalls, proxies, and threat detection solutions to securely access cloud-hosted assets while still complying with Zero Trust. What is the Role of Network Segmentation in Reducing Attack Surface? Network segmentation puts obstacles up between different parts of the network. If attackers compromise one segment of the network, they will be unable to gain instant access to the rest of the network. Instead, they will have to spend additional time and resources breaking into other network segments. This increases the chance that security teams can detect the intruder and remediate the attack before catastrophic damage is done. What is Secure Access Service Edge (SASE)? SASE is an emerging concept that provides a level of security appropriate to complex cloud-enabled enterprises with distributed remote users. It combines wide area network (WAN) with network security services like CASB, firewall-as-a-service, and Zero Trust into a unified service delivered through the cloud. This gives security leaders real-time data on their cloud security posture and allows them to accurately assess network risks continuously. What is threat detection and threat intelligence? Threat detection tools include Intrusion Prevention Systems (IPS), sandboxes, and Security Information and Event Management platforms: Intrusion Prevention Systems (IPS) identify and block unauthorized network activity, often in conjunction with firewalls and other security tools. Sandboxing allows users to download and open suspicious files in a simulated IT environment. If the file launches malware, the sandbox application will close and delete the file without allowing it to harm the system. Security Information and Event Management (SIEM) platforms allow security operations personnel to conduct real-time monitoring and respond to threats as soon as they occur. How do network security solutions help with data loss prevention? (DLP) Network security tools prevent hackers from interacting with sensitive data and block attempts to exfiltrate that data and use it to extort users. DLP solutions help security teams identify and classify sensitive information so that they can put the appropriate security controls in place to protect it. Without this step, it would be very difficult to tell when data breaches result in the loss of protected data because security teams would not have a clear idea of where that data is. In addition to network security, many organizations are also relying on enterprise data backup and recovery solutions in the event of a disaster, their cloud data is preserved and easily retrievable. Can network security solutions help with email security? Some network security tools include valuable email security and anti-phishing features. For example, some next-generation firewalls can detect when authorized users attempt to input their login credentials on spoofed websites. They prevent the data from leaving the network and warn the user that they have been targeted by a phishing attack. Multi-layered security solutions are crucial to establishing secure workflows. What is the role of Virtual Private Networks (VPN) in Network Security? VPNs allow users to encrypt their traffic and interact with protected information even when they don’t trust their own internet connection. This is important for employees interacting with remote records while traveling, where hackers can easily create fake Wi-Fi hotspots designed to look like well-known public networks. Some VPNs also anonymize user identities, allowing them to access content they would not otherwise be able to. What is IoT’s impact on Network Security? The Internet of Things presents many challenges to operational security, especially for large enterprises and industrial organizations. IoT devices rarely benefit from the kind of built-in security protections that desktop workstations and mobile phones have, making them an easy target for hackers. Security leaders need to group IoT devices together and protect them with strict security policies enforced by high quality firewalls and other tools. Mitigating Distributed Denial of Service (DDoS Attacks) Hackers may attack organizations by preventing other users from accessing their services. They may even use these attacks to disrupt firewalls and create an opening through which they can launch additional attacks. Protecting network assets from DDoS attacks requires implementing firewalls that can detect these attacks and drop the malicious connections hackers are trying to make. Next-generation firewalls have additional resources available for doing this, and can even defend against complex multi-session attacks. What are network security best practices? Network security policies and firewall rules must balance the need for security with the need for easy and accessible workflows. If security tools prevent legitimate users from accessing the assets they need, it may impact production. Similarly, security leaders need to deploy limited resources efficiently. Automation helps ensure security team members can dedicate their time to important strategic initiatives instead of high-volume, low-impact tasks. What is the role of Managed Security Service Providers (MSSPs)? MSSPs help growing organizations enhance operational security without requiring them to build, deploy, and staff their own security operations center. This allows them to save a great deal of money compared to the cost of building in-house security capabilities. It also grants organizations access to specialist security talent they might not otherwise be able to afford. Instead of paying for unpredictable security expenditures, organizations can pay a consistent monthly fee according to the services they actually use.

Cloud Security Sunburst Backdoor, Part III: DGA & Security Software Rony Moshkovich 2 min read Rony Moshkovich Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 12/22/20 Published In the previous parts of our blog ( part I and part II ), we have described the most important parts of the Sunburst backdoor functionality and its Domain Generation Algorithm (DGA). This time, let’s have a deeper look into the passive DNS requests reported by Open-Source Context and Zetalytics . The valid DNS requests generated by the malware fall into 2 groups: DNS requests that encode a local domain name DNS requests that encode data The first type of DNS requests allows splitting long domain names into separate requests. These requests are generated by the malware’s functions GetPreviousString() and GetCurrentString() . In general, the format of a DNS request that encodes a domain name may look like: USER_ID.NUM.COMPUTER_DOMAIN[.]appsync-api.us-west-2[.]avsvmcloud[.]com where: USER_ID is an 8-byte user ID that uniquely identifies a compromised host, encoded as a 15-character string NUM is a number of a domain name – either 0 or 1, encoded as a character COMPUTER_DOMAIN is an encoded local computer domain Let’s try decoding the following 3 DNS requests: olc62cocacn7u2q22v02eu.appsync-api.us-west-2.avsvmcloud.com r1qshoj05ji05ac6eoip02jovt6i2v0c.appsync-api.us-west-2.avsvmcloud.com lt5ai41qh5d53qoti3mkmc0.appsync-api.us-west-2.avsvmcloud.com String 1 Let’s start from the 1st string in the list: olc62cocacn7u2q22v02eu.appsync-api.us-west-2.avsvmcloud.com. In this string, the first 15-character string is an encoded USER_ID : “olc62cocacn7u2q” . Once it is base-64 decoded, as explained in the previous post, it becomes a 9-byte byte array: 86 7f 2f be f9 fb a3 ae c4 The first byte in this byte array is a XOR key: 0x86 . Once applied to the 8 bytes that follow it, we get the 8-byte user ID – let’s take a note and write it down, we will need it later: f9 a9 38 7f 7d 25 28 42 Next, let’s take the NUM part of the encoded domain: it’s a character “2” located at the position #15 (starting from 0) of the encrypted domain. In order to decode the NUM number, we have to take the first character of the encrypted domain, take the reminder of its division by 36 , and subtract the NUM ‘s position in the string “0123456789abcdefghijklmnopqrstuvwxyz” : num = domain[0] % 36 – “0123456789abcdefghijklmnopqrstuvwxyz”.IndexOf(domain.Substring(15, 1)); The result is 1 . That means the decrypted domain will be the 2nd part of a full domain name. The first part must have its NUM decoded as 0. The COMPUTER_DOMAIN part of the encrypted domain is “2v02eu” . Once decoded, using the previously explained method, the decoded computer domain name becomes “on.ca” . String 2 Let’s decode the second passive DNS request from our list: r1qshoj05ji05ac6eoip02jovt6i2v0c.appsync-api.us-west-2.avsvmcloud.com Just as before, the decoded 8-byte user ID becomes: f9 a9 38 7f 7d 25 28 42 The NUM part of the encoded domain, located at the position #15 (starting from 0), is a character “6” . Let’s decode it, by taking the first character ( “r” = 114 ), take the reminder of its division by 36 ( 114 % 36 = 6 ), and subtracting the position of the character “6” in the “0123456789abcdefghijklmnopqrstuvwxyz” , which is 6 . The result is 0 . That means the decrypted domain will be the 1st part of the full domain name. The COMPUTER_DOMAIN part of the encrypted domain is “eoip02jovt6i2v0c” . Once decoded, it becomes “city.kingston.” Next, we need to match 2 decrypted domains by the user ID, which is f9 a9 38 7f 7d 25 28 42 in both cases, and concatenate the first and the second parts of the domain. The result will be “city.kingston.on.ca” . String 3 Here comes the most interesting part. Lets try to decrypt the string #3 from our list of passive DNS requests: lt5ai41qh5d53qoti3mkmc0.appsync-api.us-west-2.avsvmcloud.com The decoded user ID is not relevant, as the decoded NUM part is a number -29 . It’s neither 0 nor 1 , so what kind of domain name that is? If we ignore the NUM part and decode the domain name, using the old method, we will get “thx8xb” , which does not look like a valid domain name. Cases like that are not the noise, and are not some artificially encrypted artifacts that showed up among the DNS requests. This is a different type of DNS requests. Instead of encoding local domain names, these types of requests contain data. They are generated by the malware’s function GetNextStringEx() . The encryption method is different as well. Let’s decrypt this request. First, we can decode the encrypted domain, using the same base-64 method, as before . The string will be decoded into 14 bytes: 7c a5 4d 64 9b 21 c1 74 a6 59 e4 5c 7c 7f Let’s decode these bytes, starting from the 2nd byte, and using the first byte as a XOR key. We will get: 7c d9 31 18 e7 5d bd 08 da 25 98 20 00 03 In this array, the bytes marked in yellow are an 8-byte User ID, encoded with a XOR key that is selected from 2 bytes marked in red. Let’s decode User ID: for ( int i = 0 ; i < 8 ; i++) { bytes[i + 1 ] ^= bytes[ 11 - i % 2 ]; } The decoded byte array becomes: 7c f9 a9 38 7f 7d 25 28 42 25 98 20 00 03 The User ID part in marked in yellow. Does it look familiar? Indeed, it’s the same User ID we’ve seen before, when we decoded “city.kingston.on.ca” . The next 3 bytes marked in red are: 25 98 20 . 2 0x59820 The first number 2 stands for the size of data that follows – this data is 00 03 (selected in green). The number 0x59820 , or 366,624 in decimal, is a timestamp. It’s a number of 4-second periods of time since 1 January 2010. To obtain the real time stamp, we need to multiple it by 15 to get minutes, then add those minutes to 1 January 2010: var date = ( new DateTime( 2010 , 1 , 1 , 0 , 0 , 0 , DateTimeKind.Utc)).AddMinutes(timestamp * 15 ); For the number 0x59820 , the time stamp becomes 16 July 2020 12:00:00 AM – that’s the day when the DNS request was made. The remaining 2 bytes, 00 03 , encrypt the state of 8 security products, to indicate whether each one of them is running or whether it is stopped. The 8 security products are: Windows Live OneCare / Windows Defender Windows Defender Advanced Threat Protection Microsoft Defender for Identity Carbon Black CrowdStrike FireEye ESET F-Secure 2 states for 8 products require 2 * 8 = 16 bits = 2 bytes. The 2 bytes 00 03 in binary form are: 00 00 00 00 00 00 00 11 Here, the least-significant bits 11 identify that the first product in the list, Windows Live OneCare / Windows Defender, is reported as ‘running’ ( 1 ) and as ‘stopped’ ( 1 ). Now we know that apart from the local domain, the trojanised SolarWinds software running on the same compromised host on “city.kingston.on.ca” domain has also reported the status of the Windows Defender software. What Does it Mean? As explained in the first part of our description, the malware is capable of stopping the services of security products, be manipulating registry service keys under Administrator account. It’s likely that the attackers are using DNS queries as a C2 channel to first understand what security products are present. Next, the same channel is used to instruct the malware to stop/deactivate these services, before the 2nd stage payload, TearDrop Backdoor, is deployed. Armed with this knowledge, let’s decode other passive DNS requests, printing the cases when the compromised host reports a running security software. NOTES: As a private case, if the data size field is 0 or 1 , the timestamp field is not followed with any data. Such type of DNS request is generated by the malware’s function GetNextString() . It is called ‘a ping’ in the listing below. If the first part of the domain name is missing, the recovered domain name is pre-pended with ‘*’ . The malware takes the time difference in minutes, then divides it by 30 and then converts the result from double type to int type; as a result of such conversion, the time stamps are truncated to the earliest half hour. 2D82B037C060515C SFBALLET Data: Windows Live OneCare / Windows Defender [running] 11/07/2020 12:00:00 AM Pings: 12/07/2020 12:30:00 AM 70DEE5C062CFEE53 ccscurriculum.c Data: ESET [running] 17/04/2020 4:00:00 PM Pings: 20/04/2020 5:00:00 PM AB902A323B541775 mountsinai.hospital Pings: 4/07/2020 12:30:00 AM 9ACC3A3067DC7FD5 *ripta.com Data: ESET [running] 12/09/2020 6:30:00 AM Pings: 13/09/2020 7:30:00 AM 14/09/2020 9:00:00 AM CB34C4EBCB12AF88 DPCITY.I7a Data: ESET [running] 26/06/2020 5:00:00 PM Pings: 27/06/2020 6:30:00 PM 28/06/2020 7:30:00 PM 29/06/2020 8:30:00 PM 29/06/2020 8:30:00 PM E5FAFE265E86088E *scroot.com Data: CrowdStrike [running] 25/07/2020 2:00:00 PM Pings: 26/07/2020 2:30:00 PM 26/07/2020 2:30:00 PM 27/07/2020 3:00:00 PM 27/07/2020 3:00:00 PM 426030B2ED480DED *kcpl.com Data: Windows Live OneCare / Windows Defender [running] 8/07/2020 12:00:00 AM Carbon Black [running] 8/07/2020 12:00:00 AM Full list of decoded pDNS requests can be found here .

Firewall Change Management Firewall performance tuning: Common issues & resolutions Asher Benbenisty 2 min read Asher Benbenisty Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 8/9/23 Published A firewall that runs 24/7 requires a good amount of computing resources. Especially if you are running a complex firewall system, your performance overhead can actually slow down the overall throughput of your systems and even affect the actual functionalities of your firewall. Here is a brief overview of common firewall performance issues and the best practices to help you tune your firewall performance . 7 Common performance issues with firewalls Since firewall implementations often include some networking hardware usage, they can slow down network performance and traffic bottlenecks within your network. 1. High CPU usage The more network traffic you deal with, the more CPU time your server will need. When a firewall is running, it adds to CPU utilization since the processes need more power to execute the network packet analysis and subsequent firewall This may lead to firewall failures in extreme cases where the firewall process is completely shut down or the system experiences a noticeable lag affecting overall functionality. A simple way to resolve this issue would be to increase the hardware capabilities. But as that might not be a viable solution in all cases, you must consider minimizing the network traffic with router-level filtering or decreasing the server load with optimized 2. Route flapping Router misconfiguration or hardware failure can cause frequent advertising of alternate routes. This will increase the load on your resources and thus lead to performance issues. 3. Network errors and discards A high number of error packets or discarded packets can burden your resources as these packets are still processed by the firewall even when they ultimately turn out to be dud in terms of traffic. Such errors usually happen when routers try to reclaim some buffer space. 4. Congested network access link Network access link congestion can be caused due to a bottleneck happening between a high bandwidth IP Network and LAN. When there is high traffic, the router queue gets filled and causes jitters and time delays. When there are more occurrences of jitter, more packets are dropped on the receiving end, causing a degradation of the quality of audio or video being transmitted. This issue is often observed in VoIP systems . 5. Network link failure When packet loss continues for over a few seconds, it can be deemed a network link failure. While re-establishing the link could take just a few seconds, the routers may already be looking for alternate routes. Frequent network link failures can be a symptom of power supply or hardware issues. 6. Misconfigurations Software or hardware misconfigurations can easily lead to overloading of LAN, and such a burden can easily affect the system’s performance. Situations like these can be caused by misconfigured multicast traffic and can affect the overall data transfer rate of all users. 7. Loss of packets Loss of packets can cause timeout errors, retransmissions, and network slowness. Loss of packets can happen due to delayed operations, server slowdown, misconfiguration, and several other reasons. How to fine-Tune your firewall performance Firewall performance issues can be alleviated with hardware upgrades. But as you scale up, upgrading hardware at an increasing scale would mean high expenses and an overall inefficient system. A much better cost-effective way to resolve firewall performance issues would be to figure out the root cause and make the necessary updates and fixes to resolve the issues. Before troubleshooting, you should know the different types of firewall optimization techniques: Hardware updates Firewall optimization can be easily achieved through real-time hardware updates and upgrades. This is a straightforward method where you add more capacity to your computing resources to handle the processing load of running a firewall. General best practices This involves the commonly used universal best practices that ensure optimized firewall configurations and working. Security policies, data standard compliances , and keeping your systems up to date and patched will all come under this category of optimizations. Any optimization effort generally applied to all firewalls can be classified under this type. Vendor specific Optimization techniques designed specifically to fit the requirements of a particular vendor are called vendor-specific optimizations. This calls for a good understanding of your protected systems, how traffic flows, and how to minimize the network load. Model specific Similar to vendor-specific optimizations, model-specific optimization techniques consider the particular network model you use. For instance, the Cisco network models usually have debugging features that can slow down performance. Similarly, the PIX 6.3 model uses TCP intercept that can slow down performance. Based on your usage and requirements, you can turn the specific features on or off to boost your firewall performance. Best practices to resolve the usual firewall performance bottlenecks Here are some proven best practices to improve your firewall’s performance. Additionally, you might also want to read Max Power by Timothy Hall for a wholesome understanding. Standardize your network traffic Any good practice starts with rectifying your internal errors and vulnerabilities. Ensure all your outgoing traffic aligns with your cybersecurity standards and regulations. Weed out any application or server sending out requests that don’t comply with the security regulations and make the necessary updates to streamline your network. Router level filtering To reduce the load on your firewall applications and hardware, you can use router-level network traffic filtering. This can be achieved by making a Standard Access List filter from the previously dropped requests and then routing them using this list for any other subsequent request attempts. This process can be time-consuming but is simple and effective in avoiding bottlenecks. Avoid using complicated firewall rules Complex firewall rules can be resource heavy and place a lot of burden on your firewall performance. Simplifying this ruleset can boost your performance to a great extent. You should also regularly audit these rules and remove unused rules. To help you clean up firewall rules, you can start with Algosec’s firewall rule cleanup and performance optimization tool . Test your firewall Regular testing and auditing of your firewall can help you identify any probable causes for performance slowdown. You can collect information on your network traffic and use it to optimize how your firewall operates. You can use Algosec’s firewall auditor services to take care of all your auditing requirements and ensure compliance at all levels. Make use of common network troubleshooting tools To analyze the network traffic and troubleshoot your performance issues, you can use common network tools like netstat and iproute2. These tools provide you with network stats and in-depth information about your traffic that can be well utilized to improve your firewall configurations. You can also use check point servers and tools like SecureXL, and CoreXL. Follow a well-defined security policy As with any security implementation, you should always have a well-defined security policy before configuring your firewalls. This gives you a good idea of how your firewall configurations are made and lets you simplify them easily. Change management is also essential to your firewall policy management process . You should also document all the changes, reviews, and updates you make to your security policies to trace any problematic configurations and keep your systems updated against evolving cyber threats. A good way to mitigate security policy risks is to utilize AlgoSec. Network segmentation Segmentation can help boost performance as it helps isolate network issues and optimize bandwidth allocation. It can also help to reduce the traffic and thus further improve the performance. Here is a guide on network segmentation you can check out. Automation Make use of automation to update your firewall settings. Automating the firewall setup process can greatly reduce setup errors and help you make the process more efficient and less time-consuming. You can also extend the automation to configure routers and switches. Algobot is an intelligent chatbot that can effortlessly handle network security policy management tasks for you. Handle broadcast traffic efficiently You can create optimized rules to handle broadcast traffic without logging to improve performance. Make use of optimized algorithms Some firewalls, such as the Cisco Pix, ASA 7.0 , Juniper network models, and FWSM 4.0 are designed to match packets without dependency on rule order. You can use these firewalls; if not, you will have to consider the rule order to boost the performance. To improve performance, you should place the most commonly used policy rules on the top of the rule base. The SANS Institute recommends the following order of rules: Anti-spoofing filters User permit rules Management permit rules Noise drops Deny and alert Deny and log DNS objects Try to avoid using DNS objects that need DNS lookup services. This slows down the firewall. Router interface design Matching the router interface with your firewall interface is a good way to ensure good performance. If your router interface is half duplex and the firewall is full duplex, the mismatch can cause some performance issues. Similarly, you should try to match the switch interface with your firewall interface, making them report on the same speed and mode. For gigabit switches, you should set up your firewall to automatically adjust speed and duplex mode. You can replace the cables and patch panel ports if you cannot match the interfaces. VPN If you are using VPN and firewalls, you can separate them to remove some VPN traffic and processing load from the firewall and thus increase the performance. UTM features You can remove the additional UTM features like Antivirus, and URL scanning features from the firewall to make it more efficient. This does not mean you completely eliminate any additional security features. Instead, just offload them from the firewall to make the firewall work faster and take up fewer computing resources. Keep your systems patched and updated Always keep your systems, firmware, software, and third-party applications updated and patched to deal with all known vulnerabilities.

Product Marketing Manager AlgoSec Cloud Navigating Compliance in the Cloud Iris Stein 2 min read Iris Stein Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 6/29/25 Published Cloud adoption isn't just soaring; it's practically stratospheric. Businesses of all sizes are leveraging the agility, scalability, and innovation that cloud environments offer. Yet, hand-in-hand with this incredible growth comes an often-overlooked challenge: the increasing complexities of maintaining compliance. Whether your organization grapples with industry-specific regulations like HIPAA for healthcare, PCI DSS for payment processing, SOC 2 for service organizations, or simply adheres to stringent internal governance policies, navigating the ever-shifting landscape of cloud compliance can feel incredibly daunting. It's akin to staring at a giant, knotted ball of spaghetti, unsure where to even begin untangling. But here’s the good news: while it demands attention and a strategic approach, staying compliant in the cloud is far from an impossible feat. This article aims to be your friendly guide through the compliance labyrinth, offering practical insights and key considerations to help you maintain order and assurance in your cloud environments. The foundation: Understanding the Shared Responsibility Model Before you even think about specific regulations, you must grasp the Shared Responsibility Model . This is the bedrock of cloud compliance, and misunderstanding it is a common pitfall that can lead to critical security and compliance gaps. In essence, your cloud provider (AWS, Azure, Google Cloud, etc.) is responsible for the security of the cloud – that means the underlying infrastructure, the physical security of data centers, the global network, and the hypervisors. However, you are responsible for the security in the cloud . This includes your data, your configurations, network traffic protection, identity and access management, and the applications you deploy. Think of it like a house: the cloud provider builds and secures the house (foundation, walls, roof), but you’re responsible for what you put inside it, how you lock the doors and windows, and who you let in. A clear understanding of this division is paramount for effective cloud security and compliance. Simplify to conquer: Centralize your compliance efforts Imagine trying to enforce different rules for different teams using separate playbooks – it's inefficient and riddled with potential for error. The same applies to cloud compliance, especially in multi-cloud environments. Juggling disparate compliance requirements across multiple cloud providers manually is not just time-consuming; it's a recipe for errors, missed deadlines, and a constant state of anxiety. The solution? Aim for a unified, centralized approach to policy enforcement and auditing across your entire multi-cloud footprint. This means establishing consistent security policies and compliance controls that can be applied and monitored seamlessly, regardless of which cloud platform your assets reside on. A unified strategy streamlines management, reduces complexity, and significantly lowers the risk of non-compliance. The power of automation: Your compliance superpower Manual compliance checks are, to put it mildly, an Achilles' heel in today's dynamic cloud environments. They are incredibly time-consuming, prone to human error, and simply cannot keep pace with the continuous changes in cloud configurations and evolving threats. This is where automation becomes your most potent compliance superpower. Leveraging automation for continuous monitoring of configurations, access controls, and network flows ensures ongoing adherence to compliance standards. Automated tools can flag deviations from policies in real-time, identify misconfigurations before they become vulnerabilities, and provide instant insights into your compliance posture. Think of it as having an always-on, hyper-vigilant auditor embedded directly within your cloud infrastructure. It frees up your security teams to focus on more strategic initiatives, rather than endless manual checks. Prove it: Maintain comprehensive audit trails Compliance isn't just about being compliant; it's about proving you're compliant. When an auditor comes knocking – and they will – you need to provide clear, irrefutable, and easily accessible evidence of your compliance posture. This means maintaining comprehensive, immutable audit trails . Ensure that all security events, configuration changes, network access attempts, and policy modifications are meticulously logged and retained. These logs serve as your digital paper trail, demonstrating due diligence and adherence to regulatory requirements. The ability to quickly retrieve specific audit data is critical during assessments, turning what could be a stressful scramble into a smooth, evidence-based conversation. The dynamic duo: Regular review and adaptation Cloud environments are not static. Regulations evolve, new services emerge, and your own business needs change. Therefore, compliance in the cloud is never a "set it and forget it" task. It requires a dynamic approach: regular review and adaptation . Implement a robust process for periodically reviewing your compliance controls. Are they still relevant? Are there new regulations or updates you need to account for? Are your existing controls still effective against emerging threats? Adapt your policies and controls as needed to ensure continuous alignment with both external regulatory demands and your internal security posture. This proactive stance keeps you ahead of potential issues rather than constantly playing catch-up.
