Starting with the abbreviation itself, “SOC” stands for Security Operations Center, a centralized unit that handles the security operations of an organization. A SOC is a critical unit for any organization regardless of its size. The prime objective is to “provide a situational awareness using a combination of technologies to properly identify, analyze, investigate, communicate, respond, and report cybersecurity incidents.” Also, SOC analysts will scan applications to identify potential cyber threats or ongoing cyber attacks (e.g., intrusion, compromise), determine if the event is a genuine incident, and assess the immediate impact on the business.
With new cyberattacks making headlines almost every day, the significance of cybersecurity cannot be overstated. If a SOC is not already part of an organization, the focus should be on building and managing a SOC team. Cybersecurity enthusiasts will recognize this as a lucrative opportunity to help the organization and build a career simultaneously.
Staffing SOC Team
A SOC team continuously monitors and analyzes the security infrastructure of an organization for any potential cyber threats lurking upon, or that might’ve already penetrated the existing security layer. It consists of a wide range of cybersecurity professionals, from analysts to managers and even, engineers. They also coordinate with the Computer Security Incident Response Team (CSIRT) in organizations that are large enough to have both. Usually, organizations prefer an internal SOC team, but they can be outsourced, too.
What’s the difference between a CSIRT and a SOC team? The SOC team primarily works in the Identify, Protect, and Detect functions, and a CSIRT works mostly in the Respond and Recover functions.
Security team composition can vary, and staffing such a team entirely depends upon the requirements of the organization.

How Does SOC Work?
A SOC team is not only responsible for developing security strategies and implementing defensive measures, but also to detect, analyze, and respond to security incidents. Sometimes, the team deals with additional responsibilities, such as forensic analysis, cryptanalysis, and reverse engineering.
The work of a SOC team starts with defining a strategy to gain executive support and integrate business-specific goals from different departments. Once the plan is drafted, the SOC team ensures that the infrastructure supports the implementation. A standard SOC infrastructure includes firewalls, intrusion detection and prevention systems (IDS/IPS), Security Event and Incident Management (SIEM) system, and other breach cybersecurity solutions and tools. The infrastructure uses various technologies to collect data through data flows, data packet capturing, Syslog, telemetry, and other methods, which is then analyzed by the SOC team. While continuous network monitoring to discover vulnerabilities is critical to data protection, regulatory compliance is essential to maintain the business.
What Is a SOC Analyst?
SOC analysts are usually the first responders to security incidents – the front-line defenders for analyzing cyberattacks. They start by reviewing incident alerts, then run a vulnerability assessment, followed by reporting it to Tier 2 professionals. The Tier 1 professionals ensure that the team gets the functional security monitoring tools (with right configuration). SOC analysts work alongside expert security analysts and managers.
These front-line professionals identify and analyze the cyber attacks, and then coordinate-response with Tier 2 professionals to complete required assessment reports. Based on the need of organizations, SOC analysts may be provided with additional responsibilities such as disaster recovery.
