Micro-segmentation Questions and Answers
As the first line of defense for your data, firewalls handle huge amounts of traffic for your business every day of the year. This makes it vital to protect your data center - and your customer’s valuable personal data - with firewall policies that work effectively and efficiently. Micro-segmentation is an ideal way to install security policies that help de-clutter your firewalls and create a more secure hybrid cloud environment that keeps your traffic safer and blocks potential breaches from corrupting the servers.
Micro-segmentation allows an organization to increase the level of security while keeping their business network requirements. In theory, Micro-segmentation allows communication only for communications that are needed for business. All other communications are blocked. This method increases the difficulty for cyber hackers to harm the organization.
When planning to utilize the Micro-segmentation method, the default setting should be moved to “Allow all”. This ensures the hybrid cloud environment can easily be installed, as the setting works by not blocking legitimate traffic and possibly breaking the connectivity to existing applications. Over time, in order for the virtual firewalls to keep filtering and blocking harmful traffic from invading the servers, the default settings will need to be replaced with bespoke rules.
If your firewalls are not managed correctly, this could present a huge risk to your business and valuable data. Outdated rules can lead to attacks against your servers and possibly break important business applications that are vital to your operations. By migrating to virtual firewalls through Micro-segmentation, your security policies will be solidified and well protected against cybercriminals, halting unauthorized movement and increasing the positive connections between your servers.
Managing firewalls manually can be not only a time-consuming task but also costly due to the need for trained IT staff members and the possible installation of software and also extra hardware. But by automating the firewalls on your server environments and devices, you may begin micro-segmentation, which creates a virtual firewall on every one of your servers. Depending on the number of servers at your organization, manual upkeep will create an overuse of resources that can be used more valuably somewhere else.
AlgoSec unitizes a network segmentation method of security that ensures all of your firewalls are connected and working together to protect critical data. By creating multiple firewalls through Micro-segmentation, lateral movement across servers such as cyber attacks will be limited, but without blocking any services critical to your business operation. This, in turn, keeps your security policies clean and consistent across the complete data center.
Before creating a new risk policy in your network it is important to understand what applications are running within the organization. After running sniffing technologies, the security team can better understand the required communications for your organization. Later the security zones will be defined in a way which is optimal for ensuring that these communications and not blocked by firewall rules.

In this webinar, Kyle Wickert, Worldwide Strategic Architect at AlgoSec, will get you started on your micro-segmentation journey.
AlgoSec's Cloud Network Security Solution
Unlike hardware-based firewalls, micro-segmentation creates a virtual network that protects your data from harmful attacks and invasive server breaches
Network discovery allows security managers to learn which communications are running in their network, usually software applications. Best practice recommends keeping servers of each application in the same security zone
Micro-segmentation allows greater east-west communication between servers, bypassing perimeter-based security tools and reducing lateral exploration of your data by cyber hackers
Tailor security policies according to the different types of traffic in your servers, controlling the network and application flows flawlessly and easily
Automatically migrates application connectivity and provides a unified security policy through easy-to-use workflows, risk assessment, and security policy management
The Micro-segmentation method offers a high level of virtual firewalling on every host server, providing increased visibility across on-site and cloud environments
Micro-segmentation creates successful security policies without requiring hardware-based firewalls
By using advanced automation, security managers are able to perform maintenance and changes in a Micro-segmented environment without expanding the workforce
The micro-segmented virtual environment helps safeguard the data centers and zones that are your main assets
Software-only Micro-segmentation makes your servers secure without having to install costly replacement and upgraded parts
Using the AlgoSec application allows security managers to identify communications and applications in their network. These applications are taken into consideration when defining the zones
Easily define and adopt new security policies without disrupting business applications and productivity
The Micro-segmentation method tags every security policy rule on your devices and platforms to support a specific business application
Works to allow server access only to those you want to authorize as it blocks unauthorized access such as external hackers and probes
Micro-segmentation implementation smoothly and easily allows visibility and communication between traditional firewalls and host-based firewalls
Hackers and breaches are halted before they can move freely inside the network and steal valuable data
