About Micro-Segmentation

Microsegmentation is the process of dividing a large network into smaller, more manageable segments. This allows for more granular control over security and access policies, as well as making it easier to identify and isolate issues with specific systems or applications. Security can be improved by breaking up blocks of devices, networks, or users into separate task-specific areas. While micro-segmentation is a sound security practice, it seems to have been largely overlooked in favor of other security practices such as DLP and data loss prevention.

The new concept:

Microsegmentation is not a new concept. It has been implemented to great success in the past, often without being given a specific name. For example, it was used by the Allied Forces during WWII to ensure that secret information remained secure and unreadable if one portion of their communications network was compromised or taken captive. If this strategy sounds familiar, that’s because it’s also similar to how cloud storage entails using one account for multiple devices: if any single point is compromised, all other points remain safe and secure. Microsegmentation can be applied similarly within an organization (or home), allowing access to certain services and data only from trusted machines, while restricting others from those devices which are less trustworthy or pose more risk.

Microsegmentation process:

The micro-segmentation process involves the creation of smaller virtual boxes within a network, each mapped to one or more devices and/or users. These boxes (also called “zones”) represent trusted and untrusted areas on your network, as well as those that may house sensitive data. Once these zones are determined, access policies can be configured for each zone to allow only trusted information and actions on any given device. For example, if you had two servers (one used for development and the other hosting mission-critical enterprise applications), you could use micro-segmentation to ensure that an employee’s device couldn’t access the production server while allowing his PC to connect with ease. This would result in no loss of productivity while also reducing the likelihood of an inadvertent data breach or security issue.

Segmentation strategy:

With a properly implemented segmentation strategy in place, network problems will be quickly identified and isolated to a specific device or location. If a computer is compromised by malware, only that machine would be affected rather than the entire network. This makes it much easier to remediate issues when they do arise because you know where the problem exists and what caused it. Microsegmentation can also help limit damage from internal threats, such as disgruntled employees or dishonest co-workers who may use their access privileges for malicious purposes.


Microsegmentation is a powerful tool, both in terms of security and efficiency. It’s not just for the military or large corporations anymore. If you’re looking to better protect your data while also maximizing productivity with fewer resources, micro-segmentation may be right for you.
