It involves implementing measures to protect physical devices and infrastructure from unauthorized access, tampering, or theft. Failure to secure devices and hardware can lead to data breaches or unauthorized access to critical systems. Physical security measures include facilities access control systems, security guards, surveillance cameras, door and window locks, secure equipment racks, and cable locks for devices. By combining physical security measures with cybersecurity practices, organizations can establish a comprehensive security posture that reduces the risk of data breaches and unauthorized access.
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.
Exam Tips - Answering Questions on Physical Security: When answering questions about physical security in an exam, remember that it involves protecting both the network equipment and the data that the equipment houses. - Understand the different physical security methods and tools that are used. - Consider scenarios in which different physical security measures would be appropriate. - Know the possible effects of having poor physical security measures in place.
