Guide to Physical Security in CompTIA Network+

Importance of Physical Security: Physical Security refers to measures taken to protect tangible property, computer and network equipment and information from damage and unauthorized physical access. With the rise in cyber crimes, a network's physical security has become just as important as its virtual security.

What is Physical Security? Physical security involves the use of physical measures to secure a network's data and resources. This includes the use of locks, security cameras, badges, guards and secure doors among many other security measures. The aim is to prevent unauthorized access, damages and theft.

How it works: Physical security works by safeguarding the hardware and areas around the IT infrastructure. Examples include locking server rooms, setting up surveillance cameras and setting up entry restrictions. Adequately protected areas can keep unauthorized individuals from accessing sensitive data or tampering with network equipment.
