SOC as a Service (Security Operations Centre as a Service) is an outsourcing model of IT security management, in which an organisation entrusts an external provider with the responsibility of monitoring, detecting and responding to security incidents.

This approach allows organisations to benefit from the advanced skills and resources of an SOC without having to build and maintain their own in-house operations centre.

Objectives of SOC as a Service

1. Continuous Monitoring: Provide constant 24/7 monitoring of the organisation’s IT infrastructure to detect suspicious or malicious activity.
2. Threat Detection: Use advanced tools and analysis to identify potential threats and cyber attacks in real time.
3. Incident Response: Respond promptly to security incidents to mitigate the impact and quickly restore normal operations.
4. Vulnerability Management: Identify and manage vulnerabilities in systems and applications to prevent attacks.
5. Reporting and Compliance: Provide detailed reports on security incidents and support compliance with security regulations and standards.

Key Components of SOC as a Service

1. Monitoring and Detection: Using SIEM (Security Information and Event Management) systems and other monitoring tools to collect and analyse log data, security events and network activity.
2. Threat Analysis: Advanced threat analysis using machine learning, artificial intelligence and behavioural analysis techniques to identify anomalous activities.
3. Incident Management: Structured process for responding to security incidents, including identification, analysis, containment, eradication, recovery and reporting.
4. Vulnerability Management: Periodic scanning of systems to identify and assess vulnerabilities, with recommendations for their correction.
5. Threat Intelligence: Gathering and utilising threat intelligence from various sources to improve the ability to detect and respond to attacks.
6. Reporting and Compliance: Generation of regular reports that provide visibility into the state of security and help meet compliance requirements.

Benefits of SOC as a Service

• Cost Reduction: Elimination of the costs associated with setting up and running an internal SOC, including personnel, infrastructure and technology costs.
• Access to Advanced Expertise: Access to a team of security experts with specialised expertise and up-to-date knowledge of emerging threats.
• Continuous Monitoring: Continuous monitoring of the IT infrastructure, ensuring rapid response to security incidents at all times.
• Security Enhancement: Implementation of advanced, state-of-the-art security practices to protect the organisation from cyber threats.
• Flexibility and Scalability: Ability to adapt the service to the organisation’s specific needs, with the ability to scale resources as growth and needs arise.

Operational Processes of SOC as a Service

1. Data Collection: Aggregation of log data and security events from various sources, including firewalls, intrusion detection systems, endpoints and applications.
2. Event Correlation: Analysis and correlation of security events to identify patterns and detect suspicious activity.
3. Incident Prioritisation: Classification and prioritisation of incidents based on severity and potential impact on the organisation.
4. Response and Mitigation: Timely actions to contain and mitigate security incidents, with pre-defined response plans and escalation procedures.
5. Post-Incident Analysis: Review of incidents to identify root causes and improve future defences.
6. Reporting and Communication: Continuous communication with the organisation, with regular reports and briefings on security incidents and activities.

Tools used in SOC as a Service

• SIEM (Security Information and Event Management): Tools for collecting and analysing security logs and events.
• EDR (Endpoint Detection and Response): Solutions for endpoint monitoring and protection.
• NDR (Network Detection and Response): Tools for monitoring network traffic and identifying threats.
• Threat Intelligence Platforms: Platforms for collecting and analysing threat intelligence.
• Vulnerability Management Tools: Tools for scanning and managing vulnerabilities.

Final Considerations

SOC as a Service is an effective solution for organisations wishing to improve their security posture without investing heavily in internal resources. By relying on a specialised provider, companies can benefit from continuous monitoring, rapid incident response and proactive vulnerability management, significantly improving their ability to defend against cyber threats.
