SIEM vs SOAR

Among the various security automation tools available, SOAR (Security Orchestration, Automation, and Response) and SIEM (Security Information and Event Management) stand out as two vital tools that can help organizations automate some of the most time-sensitive security tasks.

SIEM focuses on data collection and analysis, providing insights into potential security issues, while SOAR automates response actions and orchestrates workflows to manage incidents effectively.

In this blog post, we're exploring how these essential tools work, the functions they cover, and how you can choose the right security automation tool for your organization.

Security automation tools began to emerge in the early 2000s as the volume and complexity of cyber threats grew beyond the capacity of manual security processes. Initially designed to automate simple, repetitive tasks, these tools have since advanced to handle more sophisticated functions, integrating with various security technologies to streamline and enhance security operations.

Today security automation tools have become indispensable in modern cybersecurity, providing essential support to security teams and enhancing overall security posture. On average, organizations that extensively implement security AI and automation save USD 1.76 million more than those that do not.

Security automation tools encompass a broad spectrum of functions, including:

• Incident Response: Automating responses to detected threats to mitigate damage quickly.
• Threat Intelligence: Collecting and analyzing threat data to provide actionable insights.
• Vulnerability Management: Scanning and identifying vulnerabilities within systems.
• Compliance Management: Ensuring adherence to regulatory standards and policies.
• 
  

Security automation tools alleviate the burden on security teams by automating repetitive and time-consuming tasks, allowing professionals to focus on strategic activities like threat hunting and incident analysis. By reducing manual workload, these tools enhance efficiency, improve response times, and increase accuracy. Automating processes also eliminates human errors and ensures consistency in results.

Gartner defines SIEM as "the market for the customer's need to analyze event data in real-time for early detection of targeted attacks and data breaches, and to collect, store, investigate, and report on log data for incident response, forensics, and regulatory compliance." Essentially, SIEM technology centralizes and analyzes event data from various security devices, network infrastructure, systems, and applications. While it primarily relies on log data, it also processes other data types like network telemetry. This data, when combined with contextual information about users, assets, threats, and vulnerabilities, is normalized to facilitate comprehensive analysis for security monitoring, user activity tracking, and compliance reporting. SIEM excels in providing real-time event analysis for security monitoring and also offers long-term analytics for historical data.

SIEM offers several key benefits:

Early Threat Detection: By analyzing event data in real-time, SIEM helps identify potential security threats and breaches early.

Comprehensive Data Aggregation: Collects and correlates data from various sources, providing a holistic view of the security landscape.

Regulatory Compliance: Supports compliance efforts by generating detailed reports required by various regulatory standards.

Contextual Analysis: Enhances the accuracy and relevance of its analysis by combining event data with contextual information.

Despite its advantages, SIEM also has some limitations:

Manual Intervention: Often requires significant human intervention to investigate and respond to incidents.

Scalability Issues: For large organizations with extensive data, SIEM can become resource-intensive and may require substantial infrastructure.

False Positives: Can generate a high number of false positives, which can overwhelm security teams and reduce the efficiency of threat detection.

Gartner defines SOAR as technologies that enable organizations to collect inputs monitored by the security operations team, such as alerts from SIEM systems and other security technologies. 

These inputs are utilized for incident analysis and triage, leveraging both human expertise and machine capabilities. SOAR aids in defining, prioritizing, and standardizing incident response activities. It enables organizations to develop incident analysis and response procedures in a digital workflow format.

SOAR offers several key benefits:

• Automation of Repetitive Tasks: Automates low-level, time-consuming tasks such as opening and closing support tickets, event enrichment, and alert prioritization.
• Enhanced Efficiency: By automating repetitive processes, SOAR frees up security analysts to focus on more strategic tasks, improving overall efficiency.
• Standardized Workflows: Allows for the creation of digital workflows that standardize incident response procedures, ensuring consistent and efficient responses.
• Integration Capabilities: Can trigger automated actions in integrated security tools, enabling complex security operations to be carried out seamlessly.
• Improved Response Time: Reduces the mean time to resolution (MTTR) by streamlining and automating incident response activities.

SOAR also comes with some limitations:

S

• Dependency on Accurate Data: The effectiveness of SOAR depends heavily on the quality and accuracy of the data it processes. Poor data quality can lead to ineffective responses.
• Maintenance and Updates: Requires regular updates and maintenance to ensure compatibility with evolving security tools and threat landscapes.
• Learning Curve: Security teams may need extensive training to effectively utilize SOAR tools and maximize their benefits.
• Complex Setup: Implementing SOAR solutions can be complex and may require significant initial configuration and ongoing management.

Organizations benefit from using both SIEM (Security Information and Event Management) and SOAR (Security Orchestration, Automation, and Response) because each serves distinct but complementary functions. SIEM excels in real-time event monitoring and threat detection by analyzing log data from various sources, providing critical alerts. However, it lacks the automated response capabilities that SOAR offers. SOAR enhances the security process by automating the validation of alerts, orchestrating incident responses, and reducing manual intervention. This combination allows for efficient threat detection and swift, automated responses, creating a strong and complete security solution.
