CompTIA Security+ Guide: Physical Security - Locks and Safes
Introduction
Locks and safes have a vital role in physical security, a fundamental concept in CompTIA Security+ exam.
Importance
Physical security is the basis of all other forms of security. Control over who can physically access to an environment ensures the protection of data, network and systems from unauthorized physical access. Locks and safes are essential tools in enforcing this control.
Concept
Locks and safes are physical security measures aimed to control access. Locks provide access control to containers, rooms, buildings, while safes offer increased protection for sensitive materials due to their durable construction.
How It Works
Locks work by restricting access via a physical or mechanical apparatus that can only be manipulated with the correct key or code. Safes work in a similar way but have additional barriers such as fireproof or waterproof construction.
Exam Tips: Answering Questions on Locks and Safes
Tip 1: Understand the layers of physical security: Deter, Detect, Delay and Respond. Locks and safes play a part in each layer.
Tip 2: Be familiar with various types of locks (e.g. deadbolt, padlock) and safes (fireproof, burglary-resistant), and their purposes.
Tip 3: Be able to identify scenarios where various forms of locks or safes would be most appropriate.
Tip 4: Remember, the goal of physical security is not to make an area impenetrable, but to make unauthorized access as difficult as possible.
