Core Exam Objectives 2: Security Architecture

Firewalls are foundational security components in network architecture that monitor and control incoming and outgoing traffic based on predetermined security policies. For CompTIA SecurityX (CAS-005)

An Intrusion Prevention System (IPS) is a proactive security component that not only detects potential threats but also actively prevents malicious traffic from entering or

An Intrusion Detection System (IDS) is a key component in security architecture that monitors network and system activities for signs of suspicious or malicious behavior.

Vulnerability scanners are essential tools in a security architecture that identify, assess, and report security vulnerabilities across networks, systems, and applications. For CompTIA SecurityX (CAS-005)

A Virtual Private Network (VPN) is an essential tool in secure network architecture that enables encrypted communication across public or untrusted networks, providing secure access

Network Access Control (NAC) is a critical component in security architecture that manages and enforces access policies for devices connecting to a network. For CompTIA

A Web Application Firewall (WAF) is a critical component in security architecture designed to protect web applications by filtering, monitoring, and blocking malicious HTTP traffic.

A proxy server acts as an intermediary between client devices and the internet, forwarding client requests to external servers and returning the responses. In security

A reverse proxy is a server that sits between client devices and backend servers, handling requests on behalf of the servers and forwarding them appropriately.

An Application Programming Interface (API) Gateway is a vital component in modern security architectures, particularly in managing communication between services in microservices architectures or complex

Network Taps are essential components in a resilient security architecture, used to capture and monitor traffic on a network for analysis without impacting the flow

In the context of resilient security architecture, collectors play a critical role by gathering data from various sources to support monitoring, analysis, and incident response.
