Perimeter Security

What Does Perimeter Security Mean?

Perimeter security is the philosophy of setting up functional apparatus or techniques at the perimeter of the network to secure data and resources. It is part of the greater security field and has its own role in active system protection.


Techopedia Explains Perimeter Security

Perimeter security is comprised of systems like firewalls and browser isolation systems. Best practices in perimeter security include threat recognition, surveillance detection and pattern analysis.

Essentially, in perimeter security, security professionals are trying to create a perimeter-based approach to secure systems and ward off threats as they enter a network. However, many areas of today’s security industry believe perimeter security to be less than entirely effective on its own. Other kinds of internal security are emerging to apply to high-quality security processes.
