A (S)ecurity (O)perations (C)enter is a centralized unit that deals with security issues on an organizational and technical level. It comprises the three building blocks of people, processes, and technology for managing and enhancing an organization's security posture.
The primary purpose of a SOC is to monitor, detect, investigate, and respond to cyber threats around the clock. SOC teams are responsible for ensuring that potential security incidents are correctly identified, analyzed, defended, investigated, and reported.
A SOC Analyst is a cybersecurity professional who works within a Security Operations Center. They are the first line of defense against cyber threats, responsible for monitoring and analyzing an organization's security posture on an ongoing basis.
Security tools identify potential threats through alerts, logs, or anomalies in system behavior.
SOC analysts prioritize incidents based on severity, potential impact, and affected assets.
Detailed analysis to understand the scope, origin, and methodology of the attack.
Immediate actions to limit the damage and prevent further spread of the threat.
Complete removal of the threat from the environment, including malware and attacker access points.
Restoring systems and services to normal operation while verifying they are no longer compromised.
Documenting lessons learned and improving security controls to prevent future similar incidents.
Security Information and Event Management (SIEM) solutions collect, analyze, and correlate log data from various sources to identify potential security threats.
Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS) monitor network traffic for suspicious activity and take action to prevent attacks.
Platforms that provide real-time information about emerging threats, vulnerabilities, and attacker tactics, techniques, and procedures (TTPs).
Endpoint Detection and Response (EDR) tools monitor endpoint devices to detect and investigate suspicious activities and provide response capabilities.
Tools like Wireshark and network flow analyzers that help SOC teams examine network traffic for anomalies and potential threats.
Automated tools that identify, classify, and prioritize vulnerabilities in computer systems, applications, and networks.
