Introduction 

Security information and event management (SIEM) systems are essential tools for supporting the functions of a security operations centre (SOC). It is an invaluable tool used by security analysts to monitor, track, identify and respond to various security threats. The tool provides an in-depth visibility into the IT Infrastructure and connected networks and devices. This helps the team keep track of all the activities and network traffic in real-time which further facilitates threat hunting and detection.  Elaborating on this in detail we will highlight further in this post, we will discuss what a SOC is, the role of SIEM in a SOC, and how to effectively use a SIEM system to support SOC functions.

What is a security operations centre (SOC)?

A security operations centre (SOC) is a team of security professionals responsible for monitoring, detecting, and responding to security threats within an organization. The SOC typically includes analysts, engineers, and managers who use a variety of security tools and techniques to identify and mitigate security risks. The role of the SOC is to provide real-time visibility into an organization's IT environment and help identify potential security threats. This might include monitoring network traffic, analyzing security logs, and responding to security alerts. The SOC also plays a crucial role in coordinating the response to security incidents and ensuring that the organization's assets and data are adequately protected.

The role of SIEM in a SOC

SIEM systems are essential tools for supporting the functions of a SOC. They provide real-time visibility into an organization's IT environment and help identify potential security threats. One of the key benefits of SIEM is its ability to collect and analyze data from a variety of sources, such as security devices, applications, and network traffic. This data is then used to generate alerts and notifications that can help SOC analysts identify potential security threats. In addition to collecting and analyzing data, SIEM systems also provide tools for responding to potential threats. Many SIEM systems come with built-in rules and algorithms that can automatically block suspicious activities or alert security personnel to take action. This can help SOC analysts respond quickly to potential threats and prevent them from escalating.

How to effectively use SIEM to support SOC functions?

One of the most effective ways to use a SIEM to support your SOC operations is by ensuring the SIEM solution is well deployed and well configured to other systems and tools within the organization. Further, the functioning and output expected from a SIEM solution greatly depends on defining and configuring the data source, establishing appropriate technical rules, defining use cases, setting alerts and much more. Elaborating on this in detail, we have shared some best practices to consider to effectively use SIEM to support SOC functions. To effectively use a SIEM system to support SOC functions, it is important to properly configure and manage the system. Here are some best practices to consider:

1. Identify the data sources
   Start by identifying the data sources that are relevant to your organization and its security needs. This might include considering security devices, applications, network traffic, and other relevant data sources. Make sure to also include data generated from the critical assets that are most important to your organization. Identifying appropriate data sources is critical to ensure the right data is fetched and ingested for further analysis and to gain accurate threat detection and threat intelligence from the SIEM tool.  Gaining the desired output from the SIEM tool for further analysis in a SIEM tool. 
2. Configure the SIEM system to collect the right data
   The next crucial step is to, appropriately configure the SIEM system with the identified data source systems. This is to ensure the right data is collected data from the sources and identified in Step 1. This will ensure that the SOC has the right information it needs to identify potential security threats. Without appropriately configuring and integrating the SIEM with the right systems, devices and security tools will not provide the organization with the right output and further result in complete failure of threat detection. 
3. Establish rules and alerts
   Defining technical security rules and establishing the right use cases is important for appropriate alert generation in an SIEM system.  Alert generation and alerts that can help the SOC identify and respond to potential threats. This might include alerts for unusual user behaviour, unauthorized access to sensitive data, or unusual network activity. Organizations need to ensure that all the possibilities of threats are covered Make sure to also include alerts for all known, unknown and potential threats to your organization's critical assets.
4. Monitor and review
   Regularly monitor and review the data collected and the alerts set by the SIEM system. This will help the SOC team to identify potential threats and take immediate action to prevent them. It is also important to review the rules and alerts established in step 3 to ensure that they are effective and up to date. Performing regular reviews and constantly monitoring the established SIEM set-up is essential to stay updated, and relevant and stay ahead of the evolving security threat landscape.
