What is Soc L2 and How to Use It?

Cyber attacks have become a global threat with each passing day.

In parallel with this increase, the importance of Security Operations Centers (SOC) has grown exponentially. SOC centers can be called the frontline against cyber threats, as they play a critical role in preventing attacks through data analysis and monitoring.

L2, one of the two levels of the SOC, can be defined as a mid-level analysis and response layer. This layer effectively strengthens the security posture through detailed examination of simple alarms at the first level (L1) and in-depth analysis of potential threats.

SOC L2 is a specialized layer.

Definition of SOC L2

SOC L2 is a level within the Security Operations Center (SOC) and is mainly responsible for second level incident response and incident response processes. This level requires more comprehensive analysis of incidents transferred from L1, detection of sophisticated cyber threats and advanced investigation capabilities are among the main responsibilities of L2 experts.

Operators of this level, often referred to as Security Analysts, have the necessary expertise to resolve complex security incidents and are responsible for root cause analysis of incidents and developing proactive defense strategies.

Layersof Security Operations Centers

Security Operations Centers (SOCs) take a multi-layered approach to protecting systems against threats, with each layer equipped with specialized tasks. The first level (L1) deals with simple security breaches, while the second level (L2) provides a more in-depth analysis of incidents.

The L2 layer plays a vital role in the detailed investigation of cyber threats and the implementation of incident response processes. Analysts at this level focus on incidents handled by L1 that require further investigation. L2 analysts use advanced tools and techniques to decipher the root causes of possible cyber attacks.

A good SOC model is based on layers working in harmony with each other.

Transitivity between layers is an important factor in the success of the SOC. Analysts at the L2 layer examine events that pass through the L1 layer’s filter to develop more sophisticated analyses and security strategies, which is critical to strengthening the organization’s overall security posture. The in-depth knowledge and skills of L2 experts enable rapid and effective response to security incidents.

The fulfillment of an effective L2 operation is directly proportional to the continuous monitoring of these configured systems and the ability to respond immediately to critical incidents.

Infrastructure Requirements

The first step in SOC L2 deployment is to create a network infrastructure that meets the specific needs of the business. This network infrastructure should be designed to provide a secure communication platform and protect sensitive data flow. Once critical assets have been identified, firewalls, intrusion prevention systems (IPS) and other preventive security controls should be deployed to monitor and protect these assets.

The installation of SIEM systems is responsible for log management and ensures rapid response to incidents. This essential component is the center of security and the backbone of the infrastructure.

Next, integration of tools such as endpoint protection and network traffic analysis is required. This will increase capabilities in threat detection and incident response. For a secure SOC L2, it is vital that security controls are complete and correctly configured.

Continuous monitoring of the data flow is necessary to detect anomalous activities in the infrastructure. In this process, data collected by sensors and detectors is transmitted to the SIEM system for analysis and interpretation. This information plays a critical role in instantly detecting and responding to security breaches.

Apart from the SIEM system, additional threat intelligence and incident response tools should also be integrated into the infrastructure. These are vital to adapt to the ever-changing threat landscape and keep defense strategies up to date. These tools can be used in conjunction with SOAR (Security Orchestration, Automation and Response) systems for timely and effective incident response.

Finally, security assessments and penetration tests should be conducted regularly to maintain the effectiveness of the SOC L2 infrastructure.
