With the rapid evolution of technology, robust cybersecurity is vital for enterprises to protect sensitive information and systems from a range of cyber threats, including hacking, data breaches and malware attacks. As technology advances, so do the methods used by cyber criminals, necessitating the implementation of protective cybersecurity measures.
In this blog, Craig Lusher, Product Principal of Secure Solutions at Continent 8 Technologies, explores how Security Information and Event Management (SIEM) platforms and Security Operations Centres (SOCs) allow organisations to adapt to emerging threats, maintain a robust cybersecurity posture and meet regulatory compliance.
What is SIEM?
SIEM solutions consolidate security monitoring across an organisation’s diverse technology stack, enabling SOC engineers to detect and respond to threats through a unified management interface. SIEM solutions serve as the central hub of an organisation’s security system, collecting and normalising security logs and events from various IT sources including network devices, servers and security systems. They provide a central register for all security events and logs, performing event correlation, threat enrichment and analysis, filtering out informational events and promoting true security events and threats, helping organisations protect their systems from attacks and breaches.
What is SOC?
A SOC, or Managed Security Operations Centre (MSOC), such as those offered by Continent 8 and C8 Secure, is a dedicated team that focuses on safeguarding the company’s systems from security threats. Utilising various tools, such as a SIEM system, they watch over the company’s computer systems, spot any problems or attacks and respond to them quickly. The SOC functions as a cybersecurity team, ensuring everything is running smoothly and securely.
SIEM vs. SOC: the role of SIEM in SOC
SIEM systems are integral in SOC cybersecurity, offering SOC teams with a holistic view of their cybersecurity events.
To begin, the SIEM system correlates and analyses the aggregated security data from internal sources and external threat intelligence to identify any unusual or suspicious activities that could indicate a potential security issue. Upon detection, it promptly alerts the SOC team, enabling them to address the issue swiftly.
In the event of an incident, the SIEM system provides comprehensive information that assists SOC analysts in understanding the nature and severity of the threat. This insight aids in effective response and helps prevent future occurrences.
Additionally, SIEM systems support compliance efforts by generating reports and maintaining logs that demonstrate the organisation’s adherence to necessary regulations. These systems are indispensable for managing security incidents and events, facilitating efficient monitoring, detection and management of security challenges by SOC teams.
Can you have a SOC without a SIEM?
Operating a SOC without a SIEM system would be quite challenging. A SIEM system provides the centralised tool required to gather and interpret security data, which is crucial for effectively preventing, detecting, investigating and responding to threats. While a SOC might use other tools and methods, SIEM systems are integral for streamlining these processes and ensuring comprehensive cybersecurity management. SIEM systems employ advanced analytics and automation to filter and prioritise security alerts, preventing the cognitive overload, or alert fatigue, that occurs when SOC engineers manually process a constant barrage of security logs. This intelligent filtering not only reduces the risk of human error and missed security events but also optimises operational costs by allowing SOC engineers to focus their expertise on critical threat analysis and incident response rather than routine log review. The result is more efficient resource allocation and enhanced security effectiveness.
Keys to effective SIEM and SOC strategies
A successful SIEM and SOC strategy begins with defining clear objectives and goals for each system. Essential components of effective SIEM and SOC strategies include:
- Comprehensive data collection for the effectiveness of both SIEM and SOC systems. SIEM requires gathering and standardising data from various sources, such as network devices and servers. The SOC then integrates this data to ensure a complete cybersecurity overview is maintained. The more sources and context provided to the SIEM, the better it will perform.
- Real-time monitoring and alerting by SIEM are essential for quickly identifying issues. The SOC also must respond to these alerts quickly, prioritising and addressing potential threats effectively. The SIEM system’s advanced correlation and analysis capabilities help identify complex attack patterns, which SOC analysts use to understand and respond to threats. Security Orchestration and Automated Response (SOAR) technology enhances security operations by automating threat response within carefully defined parameters. By implementing pre-approved automated response protocols, SOAR significantly reduces incident response times while increasing the complexity and cost for potential attackers. This automated capability operates within a precise framework of predefined actions, allowing the SIEM system to execute security decisions autonomously yet safely. The integration of SOAR not only accelerates threat mitigation but also enables SOC analysts to focus on more complex security challenges that require human expertise and strategic thinking.
- SIEM should facilitate incident response by surfacing valuable data from the billions of events it may contain, while the SOC needs clear steps, playbooks, for handling and recording incidents – these can be customised to fit company processes and culture. SIEM makes compliance and reporting easier by automating these tasks, and the SOC ensures compliance with regulatory rules.
- Regular updates to the SIEM system for optimal performance, and the SOC should continually review and enhance its operations. Equally important is ongoing staff training, ensuring SOC analysts are well-versed in best practices to use the SIEM effectively.
- The SIEM system’s threat intelligence capabilities should be both sophisticated and multi-faceted. It must effectively ingest, evaluate and prioritise threat data from diverse sources, creating a comprehensive security perspective. This includes correlating internal intelligence gathered from customer systems with external threat feeds, industry-specific security data and intelligence collected from dark web monitoring and other specialised sources. This multi-layered approach to threat intelligence enables more accurate risk assessment and more effective security response.
- Effective communication within the organisation regarding security events, along with collaboration with IT and other teams, is crucial for effective cybersecurity management.
- Lastly, using vendor support and engaging with the cybersecurity community can provide valuable insights and help maintain a strong SIEM and SOC strategy.
