Cybersecurity threats are becoming more common, more dangerous, and more difficult to detect and mitigate. According to the Ponemon Institute’s 2021 Cost of Data Breaches study, organizations take 287 days on average to detect a breach, and more than a month to contain it. Companies of all sizes need a formal organizational structure that can take responsibility for information security and create an efficient process for detection, mitigation and prevention. This is where a security operations center (SOC) comes in. Show
In this article, you will learn:What is a security operations center?A SOC is traditionally a physical facility within an organization, which houses an information security team. Thisteam analyzes and monitors the organization’s security systems. The SOC’s mission is to protect the company from security breaches by identifying, analyzing, and reacting to cybersecurity threats. SOC teams are composed of management, security analysts, and sometimes, security engineers. The SOC works with the company’s development and IT operations teams. SOCs are a proven way to improve threat detection, decrease the likelihood of security breaches, and ensure an appropriate organizational response when incidents do occur. SOC teams isolate unusualactivity on servers, databases, networks, endpoints, applications, etc., identify security threats, investigate them, and react to security incidents as they occur. Once upon a time, it was believed that a SOC was only suitable for large enterprises. Today, many smaller organizations are setting up lightweight SOCs, such as a hybrid SOC, which combines part-time, in-house staff withoutsourced experts, or a virtual SOC, which has no physical facility at all, and is a team of in-house staff who also serve other functions. How do security operations centers work?An organization must first define its security strategy and then provide a suitable infrastructure with which the SOC team willwork. The information system that underlies SOC activity is a security information and event management (SIEM) system, which collects logs and events from hundreds of security tools and organizational systems, and generates actionable security alerts, to which the SOC team can analyze and respond. A SOC team has two core responsibilities:
Here are some of the core processes SOC teams carry out:
Focus areas of a SOCA SOC can have several different functions within an organization, which can be combined. Below are SOC focus areas with the level of importance assigned to each in the 2020 Exabeam State of the SOC Report.

The security maturity spectrum — Are you ready for a SOC?A SOC is an advanced stage in the maturity of an organization’s security. The following are drivers that typically push companies to take this step:
Different organizations find themselves at different stages of developing their security stance. We define five stages of security maturity. In stages 4 and 5, an investment in a security operations center becomes relevant and worthwhile. The future of the SOCThe security operations center is undergoing an exciting transformation. It is integrating with ops and development departments, and is empowered by powerful new technologies, while retaining its traditional command structure and roles to identify and respond to critical security incidents. We showed how SIEM is a foundational technology of the SOC, and how next-generation SIEMs, which include new capabilities like behavioral analytics, machine learning, and SOC automation, open up new possibilities for security analysts. The impact of a next-gen SIEM on the SOC can be significant. It can:
Exabeam is an example of a next-generation SIEM which combines data lake technology, visibility into cloud infrastructure, behavioral analytics, an automated incident responder, and a threat hunting module with powerful data querying and visualization.
