What Is a Security Operations Center (SOC)?

A Security Operations Center (SOC) acts as a centralized facility that enhances an organization's cybersecurity posture through the prevention of threats, real-time detections, and incident response activities at a rapid pace. SOC teams conduct continuous monitoring of IT infrastructure, looking for and analyzing potential threats, triaging security alerts, investigating and responding to incidents, and conducting threat hunting and remediation efforts. Teams work with advanced technologies (SIEM platforms) to analyze security data for valid threats to the organization, while inputting threat intelligence to predict evolving attack methods. The main goal is to protect organizational digital assets while ensuring operational resiliency from the threat of an ongoing cyber attack.

Organizations that have achieved an advanced, mature SOC capability deliver statistically significant superior security outcomes. IBM's 2025 Cost of a Data Breach Report notes that global data breach costs averaged $4.44 million, but those that matured in using AI and automation extensively within their security operations were able to save $1.9 million versus those that did not have those capabilities. Internal security teams now identify the compromise of systems in approximately 50% of breaches, thereby minimizing breach costs and timelines.

Recognizing what a SOC is begins with more than just understanding the technology; it is also an approach to cybersecurity involving people, processes, and capabilities using advanced technology to achieve the mean time to identify and mitigate breaches (241 days) that leading organizations achieve today.

Key takeaways:

• SOC centralizes threat detection, incident response, and security monitoring functions
• Combines people, processes, and technology for comprehensive cybersecurity defense
• Reduces breach detection time and minimizes business impact through rapid response
• Supports regulatory compliance through continuous monitoring and documentation

What Does a SOC Do?

SOCs continuously monitor IT infrastructure to discover malicious activity and orchestrate response and remediation actions to contain a threat before it results in substantial damage.

What is a SOC, you may ask?
A practical definition is that it is a centralized facility where technology is integrated into security operations and provides a comprehensive security operations centre.

SOC teams provide 24/7 monitoring to discover threats in an organization's digital infrastructure, using SIEM platforms and advanced security technology. Operations in the SOC consist of continuous analysis of real-time security events, incident response coordination, and proactive threat hunting capabilities. The overall goal of a SOC is to minimize cyber attack impact, protect sensitive data, and ensure confidentiality, integrity, and availability of your organization's information assets.

Core Functions of a SOC

Modern security operations centers perform several important and integrated functions to provide complete protection from the risks of cybersecurity. The operations of an SOC provide continuous monitoring, analysis, and response functions that protect organizational assets from applicable threats. These functions provide a layered defense-in-depth strategy that takes into consideration all the stages of the attack lifecycle, from detection to remediation.

1. Threat Monitoring and Detection

SOC operations start by collecting data from all the security tools deployed throughout the entire IT environment.

The main components of monitoring include:

• SIEM tools that aggregate log data from firewalls, intrusion detection systems, and endpoint protection tools
• Correlation analysis that identifies attack vectors that span multiple systems,
• Real-time alerts of suspicious behaviour across the network.

Detection Approaches

• Signature-Based Detection: This type of detection utilizes hash values, behavioural signatures, and network indicators to identify known malware families and attack tools.
• Anomaly-Based Detection: This type of detection develops baselines of normal behaviour for a system and its users and then flags deviance from that baseline for further review, knowing that deviation may indicate a compromise. Anomaly-based detection is frequently utilized in conjunction with machine learning algorithms to assist with event detection.
• User and Entity Behaviour Analytics (UEBA): This type of analytics monitors authentication patterns, file access behaviours, and privilege usages in order to detect insider threats and compromised accounts. These systems may also generate alerts when users display behaviours that could be viewed as unusual, such as accessing atypical systems or downloading unusual amounts of data.
• Integration of Threat Intelligence: This involves external data about active attack campaigns, malware families, and indicators of compromise (IOCs) from commercial feeds and/or by virtue of sharing programmes with the government.
• Network Traffic Analysis: This analysis involves the review of all communication patterns and data flows in order to identify indicators of command and control communications, data exfiltration attempts, and lateral movement events through the application of deep packet inspection.

2. Alert Triage and Incident Investigation

SOC analysts receive thousands of security alerts daily from various monitoring systems.

Triage Process:

Investigation Techniques

• Digital Forensics:
• Volatile memory analysis identifies running malware processes and network connections
• Disk forensics examines file systems and registry entries to reconstruct attacker activities
• Timeline Analysis Correlates security events with system logs and user activity data to identify:
• Initial compromise vectors
• Lateral movement techniques
• Data access patterns
• Exfiltration methods

Evidence Preservation is responsible for maintaining chain of custody records and conducting forensic imaging for legal matters and regulatory investigations.

3. Incident Response and Remediation

1. Incident Response:
   Once a security incident has been identified, the SOC team takes swift action to contain the threat, minimize harm, and ultimately aim to mitigate overall impact to the business. SOC teams follow standardized incident response procedures based on incident classification and severity levels.

2. Response Framework: Detection → Containment → Eradication → Recovery → Post-Incident Analysis

3. Containment Strategies:

• Network isolation to disconnect affected systems
• Account disabling to prevent compromised credential use
• DNS blocking to prevent command and control communications

4. Eradication Activities:

• Malware removal (files, processes, persistence mechanisms)
• Vulnerability patching to address security weaknesses
• Strengthening defenses against similar attacks

5. System Recovery:

• Deploy clean system images
• Restore data from clean backups
• Validate security control configurations

Following an incident, the analysis of the event considers the documented attack techniques that were used, identifies gaps in your protections, and may update both your lessons learned from the incident and your incident response playbook.

4. Threat Hunting and Proactive Defense

Threat hunting is a proactive search for advanced threats that are evading detection from your automated detection systems.

Hunting Methodologies

• Hypothesis-Driven Hunting: An example of this is when you examine specific attack techniques, such as living-off-the-land attacks, flightless attacks, or any unusual execution of PowerShell that may indicate fileless malware.
• APT Hunting: There are threat hunting activities that directly target identifying advanced persistent threats (APTs).
• Covert channels in network traffic or data exfiltration patterns through your monitoring systems.
• Memory dumps may also be reviewed to determine if there has been injected code and
• Investigate the authentication logs for possibly privileged escalation attempts.
• Behavioural Hunting: Threat hunting can simply be blended in with looking for the indicators of compromise (IOCs) in user activity or system activity. Some examples of IOCs are unusual sequences of file accesses or administrative activity outside normal business hours.
• Detection Engineering: The result of the hunt can be utilized to create new SIEM rules, update the security tool configuration, or inform future needs for coverage of monitoring.

5. Vulnerability Management

SOC teams coordinate vulnerability assessment activities across the IT infrastructure.

Risk-Based Prioritization:

Patch Management Coordination:

• Emergency patching for zero-day vulnerabilities
• Scheduled maintenance windows for routine updates
• Compensating controls when immediate patching isn't feasible

Vulnerability Tracking:

• Monitors remediation progress and provides management visibility into exposure trends and effectiveness metrics.

6. Compliance Reporting and Audits

SOC operations generate comprehensive documentation for regulatory compliance and security audits.

Compliance Activities

Automated Reporting:

• Extract security metrics from SIEM platforms and vulnerability scanners
• Generate compliance dashboards for frameworks like SOX, GDPR, HIPAA, PCI DSS

Security Control Testing:

• Validate that safeguards operate effectively
• Document testing procedures and remediation activities
• Align testing frequencies with regulatory requirements

Incident Documentation:

• Maintain detailed records of security events and response actions
• Document breach notification procedures
• Track corrective actions for prevention

Audit Trail Preservation:

• Archive security events and access records per regulatory timeframes
• Ensure data integrity and accessibility for audit requests
• Monitor for configuration drift and policy violations

Key Roles in a SOC

SOC operations depend on specialized roles, with each role carrying specific responsibilities in monitoring, investigation, response, and management of strategic security operations. Familiarity with SOC roles is key to organizations developing their cybersecurity SOC capabilities.

Types of SOC Models

While organizations may implement different SOC models based on availability of resources, expertise requirements, control preferences, and costs that align with the business objectives and risk tolerances:

1. In-house SOC

Internal SOC operations allow maximum control of the security processes, data control, and incident response coordination while further integrating the security services into the business process and organizational culture. An internal team provisions deeper situational knowledge of the internal systems and business-specific applications than a third-party provider would have. Internal SOC provisioning requires a substantial, resource-heavy investment in security talent, technology infrastructure, and permanent staff training to maintain operations on a 24/7 basis to keep pace with a constantly changing threat landscape.

2. Outsourced SOC (MSSPs)

Managed Security Service Providers (MSSPs) provide cybersecurity expertise and experience to multiple client organizations in dedicated security operations centers. MSSPs provide beneficial economies of scale, enterprise-grade security tools, and immediate access to experience security professionals without incurring the capital cost of building an internal team and staffing the operation. Organizations benefit from experienced security processes, sophisticated threat intelligence, and predictable costs through a subscription-based model; however, they accept a diminished level of control and potential complexity when it comes to integration.

3. Hybrid SOC

SOC models bring together the benefits of both internal and outsourced SOCs. These organizations have an internal SOC team and utilize an external provider for its expertise and resources. Hybrid SOCs can balance the organization's level of control, cost, and access to specialized skills.

4. Global SOC (GSOC)

Large multinational organizations use Global SOC (GSOC) architectures to distribute their security operations to regionally-based centres while centralizing threat intelligence and policy management. According to Microsoft Security, very large organization with operations in multiple countries rely on a GSOC to coordinate their detection and response across multiple local SOCs. GSOC models operate continuously 24/7, as they use local security teams to provide optimal analyst alertness and regional expertise. Local teams will have the advantage of language capability and regulatory knowledge; however, consistent delivery of service across varied time zones and global coordination of incident response across the multiple teams creates exponential complexity.

SOC Model Comparison

Why Organizations Need a SOC

SOC functions mitigate the existential challenges faced by organizations in cybersecurity that cannot be resolved effectively through conventional reactive security approaches or stand-alone point solutions.

Proactive Defense Against Cyber Threats

Traditional security approaches provide clues to the damaging cybersecurity breaches only after normal practices, including periodic scans for vulnerabilities, have borne fruit, and only after incident response was implemented when the breach was identified.

This process allows cybercriminals to establish a persistent presence for days, weeks, or even months without detection! Advanced persistent threats may also enjoy this level of operation for varying lengths of time while organizations apply traditional security approaches.

An SOC capability allows for continuous monitoring of network traffic, logs on systems, and user behaviours, in real time, to identify malicious traffic patterns and attack indicators. Threat intelligence can also be integrated to improve contextual sensing or visibility, as can behavioural analysis tools, which rely on machine learning, to identify the most sophisticated attacks against organizations, including zero-day exploits and living-off-the-land attacks, that evade traditional security controls.

Reduced Breach Damage and Costs

An analysis provided in IBM's 2025 Cost of a Data Breach Report noted that organizations that had extensive AI and automation capabilities in the areas of security operations saved $1.9 million in breach costs compared to those without such capabilities. SOC capabilities reduce mean time to detection below industry averages and approaches by leading organizations of 241 days to identify and contain the breaches.

Identification of breaches before or very near to occurring limits the time for an attacker to reside in an organization, reduces event opportunities for exfiltration of data, and mitigates business disruption through structuring containment procedures and recovery planning. Evidence preservation capabilities aid, support and inform judicial proceedings and regulatory enquiries while maintaining customer confidence during a security incident.

Improved Compliance Readiness

Regulatory frameworks such as GDPR, HIPAA, SOX, and PCI DSS are increasingly requiring continuous monitoring and incident response capabilities commensurate with SOC operational capabilities. SOC operations will create the required security event logs, incident response documentation, and evidence of control testing, as required for regulatory compliance.

Automated compliance reporting removes the documentation burden while offering the auditor evidence of security controls' operational effectiveness. The SOC capabilities will allow for a quick assessment of a breach so that the notification to the regulator is within an assigned time limit and the organization minimizes the potential for penalties and proves it had proactive compliance in place.

Strengthened Business Continuity and Stakeholder Trust

Trust Cybersecurity incidents can interfere with the course of operations and damage stakeholder confidence. Security operations center (SOC) capabilities support timely incident response and effective communication and stakeholder confidence during a crisis. An organization with mature SOC capabilities signals that the organization has implemented security posture that proactively differentiates a company from other competitors.

In addition, vendor relationships may require security certifications and incident response capabilities before establishing business or procurement relationships. SOC capabilities can provide evidence of the organization's security maturity, supporting new business development, enabling better competitive positioning, and potentially supporting investor relations, while simultaneously reducing scrutiny from regulatory agencies.
