What are SIEM Systems for Information Security management?

Key SIEM functions

The main functions of SIEM systems security are:

• Data Collection. SIEM collects security data from various sources on a computer network, including data from clients, network devices, security management systems and other sources;

• Data storage and management. The system structures stored data, which enables efficient management of a large amount of information and supports auditing as required;

• Threat Analysis and Detection. SIEM analyses security events and monitors for security incidents;

• Correlation and event analysis. The system analyses events to identify connections and patterns between them, which allows  to identify unobvious threats or vulnerabilities;

• Incident detection and real-time alerting. When a security incident is detected, a script is automatically triggered, including blocking access, sending notifications, and other methods;

• Auditing and reporting. Domestic SIEMs allow tracking and recording user actions and other security-related events, providing administrators with the ability to draw conclusions and analytics.

Work order

SIEM operates on a continuous cycle of collecting, analysing and responding to information in real time. When a potential threat is detected, the system triggers, sends notifications and takes the necessary measures to prevent security incidents. The events that occurred are then analysed and reports are produced to help better understand the current situation and take action to improve the safety strategy.

Advantages

The main advantage of SIEM systems of Information Security is their multifunctionality, which allows to solve several important tasks at the same time. The key advantages of SIEM include:

• centralised data storage and analysis: systems collect data from different sources and store it in a database, allowing for more in-depth analysis;

• timely detection and prevention of threats: SIEMs monitor activity in real time and utilise alerts and response mechanisms to prevent incidents instantly;

• centralised reporting: SIEM systems enable reporting to help organisations comply with safety standards and regulatory requirements;

• optimise resources and increase efficiency: SIEM systems optimise the use of resources and reduce costs of security monitoring and analytics, increasing efficiency;

• integration with other security systems: SIEMs are compatible with DLP systems such as Anexet, enabling additional security information from a variety of sources.

Anexet is an excellent DLP solution that provides additional protection and control over an organisation's information. Together with SIEM systems, it creates a robust and comprehensive Information Security Management System that can effectively address today's cyber security challenges.

Conclusion

There are several motivating reasons why you should seriously consider the decision to buy a SIEM system:

• infrastructure expansion;

• need to control specialised sources;

• growing number of IS incidents;

• regulatory requirement.

Bottom line: using a SIEM system is a great solution not only for large companies, but also for small businesses and any other area where Information Security is not in the last place. Purchasing a SIEM is an investment in a powerful tool for managing Information Security and detecting security incidents.
