It involves the establishment of physical barriers and other mechanisms to secure the boundaries of a facility or property. The primary objectives of perimeter security are to deter, detect, and delay intruders from gaining unauthorized access. Physical barriers such as fences, walls, and gates can be used to impede unauthorized access, while other technologies like motion sensors, infrared detectors and security cameras can be employed to detect and deter potential intruders. Perimeter security is an essential part of the overall physical security strategy for an organization.
Perimeter Security - CompTIA Security Plus Guide
What is Perimeter Security Perimeter Security refers to the defensive strategies used to protect an organization's assets and resources from external threats. The perimeter barrier marks the boundary between an organization's internal and external network.
Why it is Important Perimeter security is crucial because it serves as the first line of defense against unauthorized access, threats, and attacks. It helps to identify and neutralize threats before they can infiltrate the network and cause significant damage.
How it Works Perimeter security operates by setting up barriers such as firewalls, intrusion detection systems (IDS), and intrusion prevention systems (IPS) to detect and prevent unauthorized access. It can include both physical measures, like gates and fences, and technological measures, like network firewalls.
Exam Tips: Answering Questions on Perimeter Security 1. Understand the different components of perimeter security and how they work together. 2. Remember that the purpose of perimeter security is to protect an organization's internal network from external threats. 3. Be familiar with different types of perimeter security measures, both physical and technological. 4. When provided with scenarios in the exam, first identify what threat is being posed, and then determine the best type of perimeter security to address that specific threat. Note: Always remember that the effectiveness of perimeter security relies on not just the strength of the barriers, but also the quality of monitoring, alerting, and response systems in place.
