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.
