What is Micro-segmentation networking:
The process of generating secure zones, both in cloud deployments and data centers is called Micro-segmentation networking. From a business perspective, organizing network security measures, firewalls, and align them properly with data servers can cost a lot of time and complicates the whole operation. With the help of a micro-segmentation stratagem, we can break the network into granular sections which add an extra level of security to safeguard important data and information from thefts and cybercrimes. It also helps a business to segregate its workload and securely organize it into the network system.
Challenges to micro-segmentation networking:
Micro-segmentation is a great option to mitigate network security policy errors. Still, organizations may face challenges while implementing micro-segmentation for their network. Because of the lack of sufficient training, employees may face hurdles to set up and operate it. The other challenges that an organization can potentially face with micro-segmentation networking are:
- Server competence to operate the hybrid cloud environment.
- Flaws in planning to appropriately map the current application structures.
- Not obtaining a firewall guideline prior to micro-segmentation implication.
- Not updating virtual firewalls on a regular basis, because virtual firewall upgradation helps to cope up with technological changes and enhances security.
So, different types of obstacles may occur at the time of installing a new structure on an existing server, and micro-segmentation is not an exception.
How micro-segmentation contribute to security:
Micro-segmentation networking segregates network security and makes it more granular. Each granule host has its own security controls, and each of them is separate in operation from each other. Apart from it, micro-segmentation helps to streamline the communication process for a business by choosing only business based communications and blocking unnecessary ones. It limits the scope for cyber hackers to run any possible hack on the network. By this, it provides security more granular in nature. Along with it, the security policies of micro-segmentation can easily coordinate with different virtual security targets such as virtual machines (VM), virtual network (VN), operating system (OS), etc.
Ideal firewall setting for installing micro-segmentation software:
When a business decides to install a micro-segmentation network, they should shift the default setting mode to ‘allow all’. By this, the system will install the hybrid cloud setting effortlessly, as the setting will not block rightful traffic, and separate its connectivity from other existing applications. To keep the virtual firewalls effective in blocking injurious traffic from entering the server, the primary settings should be substituted with modified policies.
How micro-segmentation improves firewall management: If an organization does not maintain its firewall properly, it can pose a great threat both to the business and valuable information stored in the server. Obsolete policies could not be able to prevent an attack on the server and it may possibly damage vital business applications. Adopting virtual firewalls through micro-segmentation networking can effectively strengthen and well-protect the security policy of the server and lead to a more positive connection among servers.
