It conducts post-mortem analyses of incidents, identifies security vulnerabilities, and recommends reinforcement measures. The SOC is also responsible for raising security awareness within the company by providing training and best practices for users.
What are the responsibilities of the SOC team?
A Security Operations Center (SOC) team is responsible for several essential tasks and responsibilities to ensure the security of an organization's information systems; it is responsible for monitoring, detecting, analyzing, and responding to security incidents.
Security event monitoring: The SOC team constantly monitors security events, such as security logs, alerts generated by detection tools, and network data streams. They analyze these events to identify suspicious or malicious activity.
Incident detection and analysis: When suspicious activity is identified, the SOC team takes charge and analyzes it thoroughly to understand its nature, origin, and potential impact on systems. This analysis helps determine the severity of the incident and develop an appropriate response strategy.
Incident management: The SOC team proactively manages security incidents throughout their lifecycle. This includes logging and tracking incidents, documenting actions taken, communicating with internal and external stakeholders, and conducting post-mortem analyses to identify lessons learned and improve security processes.
Collection and analysis of security data The SOC team is responsible for collecting, aggregating, and analyzing security data from various sources, such as security logs, alerts, activity reports, and forensic analysis data. This analysis helps detect trends, patterns, and indicators of compromise to better prevent future incidents.
Technological monitoring and threats: The SOC team constantly monitors the latest trends in threats and security technologies. They maintain their knowledge of emerging attack techniques, known vulnerabilities, and security best practices. This technological monitoring allows them to stay up-to-date and adapt defense strategies accordingly.
Safety awareness: The SOC team plays a key role in raising security awareness within the organization. They organize training and awareness sessions for employees to inform them about current threats, security best practices, and the steps to take in the event of an incident.
Compliance at the heart of the Security Operations Center
The challenge of compliance with the use of a SOC lies in the need to ensure that the activities of the SOC and the security measures put in place comply with applicable regulations and standards.
When companies deploy a SOC to strengthen their security posture, they must ensure that the processes, policies, and procedures adopted comply with the legal and regulatory requirements specific to their industry. These requirements may include regulations relating to the protection of personal data, information confidentiality, security incident management, and log retention.
Interpretation of regulations: Cybersecurity regulations can be complex and require in-depth analysis to understand their scope and applicability.
Data collection and storage: Regulations may impose specific requirements regarding the collection, storage, and retention of security data.
Incident and violation management: In the event of a security incident or breach, the SOC must be able to respond appropriately and in accordance with applicable regulations.
Compliance monitoring and reporting: The SOC must be able to provide regular compliance reports, which demonstrate how it complies with applicable regulations.
What is SOC-as-a-Service? Hybrid vs. Fully Outsourced
Security Operations Center (SOC) as a Service (SOC) is a security service delivery model that offers businesses the benefits of a specialized SOC without the need to create and manage an in-house SOC. It allows businesses to benefit from specialized expertise, continuous monitoring, incident response, and increased flexibility, while reducing the costs associated with setting up and maintaining an internal SOC.
SOC Outsourcing Instead of developing and maintaining an in-house SOC, the company outsources all security operations to a SOC service provider. This allows the company to focus on its core business while benefiting from the advantages of a specialized SOC.
Specialized expertise: The SOC service provider offers a team of qualified and experienced security experts. These professionals are trained to manage security incidents, analyze alerts, conduct thorough investigations, and provide security recommendations.
Advanced tools and technologies SOCaaS uses advanced threat detection tools, such as Security Information and Event Management (SIEM) systems, anomaly detection platforms, and Security Automation and Incident Response (SOAR) solutions. These tools help collect, aggregate, and analyze security data, thereby facilitating early incident detection and rapid response.
24/7 monitoring: By ensuring continuous monitoring of the company's information systems, 24 hours a day, 7 days a week, this guarantees rapid detection of suspicious or malicious activities, even outside of normal working hours.
Flexibility and scalability: By offering businesses greater flexibility and scalability, resources and services can be adjusted to meet specific business needs, whether for rapid growth, special events, or seasonal demands.
What challenges does a SOC face?
A SOC faces several challenges in its role of protecting information systems against security threats.
High volume of alerts Security operations centers (SOCs) receive a large number of alerts from various sources, such as intrusion detection tools, intrusion prevention systems, and malware detection solutions. Managing this high volume of alerts can be challenging in terms of resources and the ability to quickly identify real incidents from false positives.
Complexity of attacks: Attackers are using increasingly sophisticated techniques to bypass security defenses. Attacks are often multifactorial, targeted, and polymorphic, making their detection and analysis more complex. SOC teams must constantly stay abreast of the latest attack techniques and develop advanced skills to counter them.
Skills shortage: The cybersecurity field is facing a shortage of qualified professionals. Recruiting and retaining talent with the skills needed to analyze incidents, conduct thorough investigations, and manage security tools can be a challenge for SOCs. Therefore, training and skills development for SOC staff are becoming essential.
False positives: Security detection tools can generate false positive alerts—that is, alerts reporting incidents that are not actually malicious. Distinguishing false alerts from genuine malicious traffic can be time-consuming and resource-intensive, potentially leading to delays in detecting and responding to real incidents.

Protection of sensitive data: Security operations centers (SOCs) handle sensitive and confidential data, including security logs, analytics data, and incident information. Ensuring the protection and confidentiality of this data throughout its lifecycle, in accordance with applicable regulations, is a significant challenge for SOCs.
Scalability and infrastructure: Security operations centers (SOCs) must be able to adapt to technological advancements and the growing needs of the business. This includes the scalability of monitoring infrastructure, detection tools, and security data analytics capabilities. Sizing and upgrading the infrastructure can be challenging in terms of cost and technical complexity.
Response time and resolution: The ability to quickly detect incidents, analyze their impact, and respond appropriately is crucial for limiting damage and minimizing disruption to the business. Reducing incident response and resolution times is a constant challenge for SOC teams.
Complementarity with SOAR, SIEM, XDR and MDR
SOAR (Security Orchestration, Automation and Response): The SOC uses SOAR to automate and orchestrate security processes, thereby improving its efficiency and incident management capabilities. SOAR consolidates alerts, automates repetitive tasks, coordinates incident response activities, and facilitates in-depth investigations. The SOC leverages SOAR to reduce response times, improve the accuracy of analyses, and free up time for higher-value tasks.
SIEM (Security Information and Event Management): The SIEM is a platform used by the SOC to collect, correlate, and analyze security data from various sources. The SIEM helps the SOC centralize and visualize event logs, detect anomalies, generate alerts, and conduct in-depth investigations. The SOC relies on the SIEM to gain a comprehensive view of the network's security posture, identify suspicious activity, and proactively respond to incidents.
XDR (Extended Detection and Response): Through an advanced approach to security incident detection and response that goes beyond the traditional limitations of SIEM, the SOC uses XDR to consolidate data from multiple security sources, such as endpoints, networks, and clouds. This enables the SOC to have broad visibility into threats and incidents, improve early attack detection, and accelerate incident response through advanced data correlation. The SOC can leverage XDR to enhance its ability to detect and respond to complex threats.
MDR (Managed Detection and Response): The SOC can work closely with an MDR service to benefit from the provider's expertise in managing incident detection and response capabilities, advanced tools, and 24/7 monitoring capabilities.
