The Security Operations Centre (SOC) assists in detecting, monitoring and also responding to cyber threats. In summary, it provides services ranging from monitoring and log analysis to vulnerability management, incident response. Also, the trend is increasingly proactive threat hunting. SOC analysts monitor and control potentially malicious traffic within an organization to stop it before it becomes harmful. SOC is not responsible for the development of security policies and programs or for the architecture and implementation of security technology control systems.
However, SOC requirements are changing over time due to an increasing number of attacks and more sophisticated threats. They also face new risks because of cloud adoption and digital transformation initiatives.
Analysts cannot achieve maximum efficiency by manually looking at all the data. It is the modern SOC that analyses large volumes of data, looks for connections between them and correlates them. Additionally, it provides real-time alerts. A modern SOC requires significant automation and insight into a company’s security. It focuses on team coordination and automation to handle the increased load of events to be reviewed.
Managed Detection and Response Incident Digital Forensics Analysis premieres our optimized Cybersecurity combo-offering that features ongoing expert incident response, forensics, and remediation with additions to include proactive threat hunting services. Enhance your existing SOC’s effectiveness with expert incident response, forensics, remediation, proactive threat hunting and more.
The modern SOC has the following characteristics compared to the classical one:
- Correlation of Events from multiple logging areas
- Threat Intelligence
- 24x7x365 Activity
- Monitor, Manage and Advise
What to Keep in Mind with Modern SOC?
Do Not Be Discouraged by the Number of False Positives Reports
The SOC’s role is to centralize a multitude of alerts into one place through integrations. Many repetitive tasks are automated, and many alerts are not usable. After analysis, they are classified as false positives. Human interaction is still required to prioritize alerts, investigate them correctly, and respond, which can take up to 80% of an analyst’s time.
Relevant Case Management
Individual alerts are not sorted separately. Data must be collected and analyzed into cases and linked to specific incidents. Linking alerts to cases with relevant context is still largely a manual process. It requires skill and may require many attempts to ensure that all relevant alerts are put into the correct cases.
Analyze the Root Cause
Investigation and resolution of some alerts often leads to changes in individual measures, for example. However, many alerts are not resolved or do not get to the root cause. This represents a lot of extra work. However, resolving incidents without justifying their cause increases the security risk.
Establish Relevant Workflows
Due to the constantly changing and evolving environment, it is necessary to develop appropriate workflows that can adapt and improve. SOAR Automation can partly help in this matter.
Emphasis on Collaboration
SOC is an important component in enterprise risk management. Pressures are increasing, particularly as a result of cloud adoption, enterprise mobility and digital transformation initiatives.
Success in the modern SOC is assured when finding a way to automate key but repetitive tasks while offloading analysts to focus on more valuable functions such as threat scanning and vulnerability management. SOAR enables greater collaboration between teams. However, automation needs to think about mitigating the number of false positives and providing insight into patterns and recommending actions.
