  • Reviewing the alerts to determine their relevance
  • Monitoring event logs
  • The detection of suspicious activities
  • Information gathering for investigation
  • The deployment of initial response and isolation measures when incidents occur.

Level 2 analysts focus on priority incidents and use threat intelligence data to define containment strategies. Their primary mission includes:

  • Incident investigation
  • Determining the root cause
  • The provision of detailed incident reports
  • The formulation of remediation recommendations

Level 3 experts, known as threat hunters, are responsible for identifying previously unknown threats and vulnerabilities. Specialized roles such as security consultants, malware analysts, and vulnerability managers also play crucial roles in continuously improving security by responding to threats.

The security operations manager, or SOC Manager, oversees all daily operations and coordinates the teams.

How a 24/7 SOC works

The technologies and tools used by a SOC are essential for effective security operations. Among them, Security Information and Event Management (SIEM) is at the heart of this infrastructure. SIEM enables:

  • Monitor and analyze security data for detect anomalies
  • Integrate a log well
  • Use configurable detection tools for effective monitoring.

Other tools such as:

  • IDS and IPS systems, which monitor network traffic to detect and prevent malicious activities.
  • The EDR, which enables continuous monitoring of endpoints and offers advanced threat detection capabilities.
  • NDR, a complementary tool to SIEM and EDR for network detection.
  • XDR, which correlates EDR data and other information to quickly detect threats.

Advanced detection tools enable the identification of malicious behavior and rapid response. SOAR improves the efficiency of security operations by integrating various tools and automating repetitive tasks.

Threat intelligence is crucial for the rapid detection of cyber threats and increased responsiveness. Furthermore, artificial intelligence and machine learning are becoming essential tools in cybersecurity, enabling the analysis of larger volumes of data and the identification of complex patterns.

Common challenges faced by SOC teams

SOC teams often face a high volume of alerts, which can lead to information overload and fatigue. The threat landscape is evolving rapidly, with new cybercrime techniques and tactics constantly emerging. Effectively integrating security tools is also a challenge, as many systems do not communicate well with each other.

These challenges can affect the ability of SOC teams to detect and respond effectively to security incidents. It is therefore crucial to find solutions to overcome these obstacles and improve the overall performance of the SOC.

Solutions to overcome SOC challenges

Process automation accelerates incident response by reducing the time needed to detect and address threats. SOC teams use artificial intelligence tools to automate certain incident response processes. This allows analysts to focus on more strategic and complex tasks.

Ongoing training for teams is essential to ensure they remain competent in the face of evolving threats and technologies. By leveraging artificial intelligence, SOCs can improve threat detection by analyzing larger volumes of data and identifying complex patterns.

Hierarchical structure of the SOC
