Domain 3: Security Operations and Monitoring
Security operations and monitoring is the largest domain in the CySA+ syllabus, accounting for 25% of the exam content. This domain focuses on monitoring and managing security operations, including the use of tools and techniques to detect, analyze, and respond to security incidents.
Core topics include:
• Security information and event management (SIEM): Understanding SIEM tools and how they are used to collect, analyze, and respond to security alerts.
• Monitoring and logging: You will be tested on your ability to monitor system and network logs to detect abnormal behavior and potential security breaches.
• Network monitoring: This includes analyzing network traffic for signs of suspicious activity, such as unauthorized access attempts or data exfiltration.
To succeed in this domain, you need a solid understanding of network architecture, protocols, and common network-based attacks, as well as hands-on experience with SIEM and monitoring tools like Splunk, Wireshark, and others.
