Automate and elevate: The SIEM-SOAR symphony in SOCs

As our reliance on technology deepens, the threat of cyberattacks becomes an ever-present concern for organisations. With incidents ranging from personal data breaches to large-scale corporate hacks, safeguarding assets and sensitive information has never been more challenging. The increasing sophistication of cybercriminals underscores the urgent need for robust security measures. In this critical environment, Security Operations Centres (SOCs) play an essential role in defending organisations against cyber threats, enabling security teams to effectively manage vast amounts of data and respond to incidents swiftly.

How SIEM and SOAR power cyber defences

In the ever-evolving landscape of cybersecurity, Security Operations Centres (SOCs) play a critical role in defending organisations against cyber threats. To effectively manage vast amounts of security data and respond to incidents swiftly, SOCs rely on two essential technologies: Security Information and Event Management (SIEM) and Security Orchestration, Automation, and Response (SOAR). These tools form the backbone of modern SOC operations, enhancing threat detection, investigation, and response capabilities. Let’s delve into the crucial roles of SIEM and SOAR in the SOC journey, showcasing their unique advantages, core functionalities, and the synergistic benefits they offer when integrated.

SIEM: The eyes and ears of the SOC

Imagine a central nervous system for security. SIEM acts as that very system, collecting security events in real-time from firewalls, Intrusion Detection Systems (IDS), endpoints, and other sources within an organisation. It aggregates this vast amount of data, normalises it for better analysis, and correlates events to identify potential threats.?

"63% of threats SOC Team members manually review in a typical workday are low priority / false positives; so validating incidents that aren’t even a real threat consumes one third of their typical workday.1"

Here's how SIEM empowers SOC analysts:

Log management:?SIEM collects logs from different sources such as firewalls,?intrusion detection systems , servers, and applications. These logs provide valuable insights into network activities and potential security threats. By centralising and retaining logs from various sources, it provides unified visibility and simplifies log management.

Event correlation:?By correlating events from multiple sources, SIEM identifies patterns and anomalies that may indicate security incidents. This helps in reducing false positives and highlighting genuine threats.

Alerting and reporting:?SIEM generates alerts based on predefined rules and thresholds. It also provides detailed reports and dashboards to help security analysts understand the security posture of the organisation, including compliance adherence reports for standards like?PCI DSS , HIPAA, GDPR and more.

Incident detection and response:?SIEM helps in detecting and responding to security incidents in real-time. It provides context and visibility into incidents, enabling security teams to take appropriate action.

SOAR: The power of automation

Enter SOAR, the SOC's secret weapon for efficiency. It takes the insights gleaned from SIEM and automates repetitive tasks, orchestrates workflows, and facilitates coordinated responses to security incidents.? Think of it as the "action arm" to SIEM's "analytical mind”.?

"87% of SOC team members say that automation would save some or a lot of time during threat response.1"

The core functions of SOAR include:

Automation: SOAR automates routine tasks such as data collection, enrichment, and initial analysis. This reduces the manual workload on security analysts and speeds up incident response.

Orchestration:?SOAR integrates with various security tools and systems, orchestrating workflows across different platforms. This ensures seamless collaboration and data sharing among security tools.

Incident response: SOAR provides playbooks and automated response actions to guide security teams through the?incident response process . It ensures consistent and timely responses to security incidents.

Case management: SOAR offers case management capabilities, allowing security teams to track and manage incidents from detection to resolution. It also provides a centralised repository for incident data, facilitating collaboration and reporting.

The synergistic power of SIEM and SOAR

While SIEM and SOAR have distinct functionalities, their integration creates a powerful synergy that enhances the overall capabilities of a SOC. Here’s how they complement each other:

SIEM feeds data to SOAR: SIEM’s event correlation capabilities combined with SOAR’s automation enable faster and more accurate threat detection. SOAR can automate the initial triage and enrichment of alerts generated by SIEM, providing security analysts with actionable intelligence.

Beyond basic response: The integration of SIEM and SOAR streamlines the incident response process. SIEM identifies potential threats, and SOAR orchestrates the response actions, ensuring timely and coordinated responses. Automated playbooks in SOAR can execute predefined actions based on SIEM alerts, reducing the Mean Time To Respond (MTTR).

Empowering analysts: SIEM collects and aggregates security data, while SOAR automates and orchestrates workflows. This combination allows security teams to focus on high-value tasks, such as threat hunting and investigation, rather than spending time on repetitive tasks.

Comprehensive visibility and reporting: SIEM provides visibility into security events and incidents with threat trail analysis, while SOAR offers a centralised platform for managing and tracking incidents. Together, they provide comprehensive visibility into the organisation’s security posture and facilitate detailed reporting.

Conclusion

The journey of a SOC is fraught with challenges, from managing vast amounts of security data to responding to sophisticated cyber threats. SIEM and SOAR are indispensable tools that enhance the capabilities of SOCs, enabling them to detect, investigate, and respond to incidents effectively. The synergy between SIEM and SOAR not only improves the efficiency and effectiveness of security operations but also empowers security teams to stay ahead of evolving threats. As cyber threats continue to grow in complexity and volume, the integration of SIEM and SOAR will remain crucial in fortifying the defences of organisations and ensuring a robust?cybersecurity ?posture.
