What is SIEM? A Comprehensive Guide

Today any organization that holds a website and needs to connect with networks and the cyber world

must have a solid SIEM solution. 

Without a robust and professional security solution, associations can’t work with confidence and in a

smooth manner.

Security information and event management (SIEM) is a way to deal with security management that combines SIM (security information management) and SEM (security event management) capacities into one security management system.

How Does SIEM Work?

The technique SIEM software functions is by collecting log and event data generated by host systems,

security devices, and apps throughout the infrastructure of an organization and organizing it on

a centralized platform. SIEM software recognises this data and groups it into categories,

such as malware activity, unsuccessful and successful login attempts, and other potentially harmful

activities, from antivirus events to firewall logs.

When an incident or event is identified, analyzed and classified, SIEM works to deliver reports

and notifications to the proper stakeholders within the association. Also, a SIEM helps satisfy

regulatory compliance requirements by providing auditors a view into their association

compliance status through continuous monitoring and reporting capabilities.

Why is SIEM important?

SIEM is important because it makes it easier for enterprises to manage security by filtering massive amounts of security data and focusing on  the security alerts the software creates.

A SIEM system can also assist an organisation in meeting compliance requirements by generating reports that include all logged security events from these sources. Without SIEM software, the organisation would have to manually collect log data and aggregate reports.

SIEM has been seen as a necessary addition to the security manager's toolkit for years now. However, the market for SIEM software tends to be complex and confusing, and many have even called it a rip-off. It is easy to use, making it appealing to users who are inexperienced with SIEM work flow.

The following are the most important reasons why businesses require a SIEM solution:

• Detecting Incidents - A SIEM solution detects incidents that would otherwise go undetected. This technology examines log sections for indicators of malicious activity. Furthermore, because it collects events from all sources across the network, the system can reconstruct the attack timeline to help determine the nature and impact of the attack. The platform sends recommendations to security controls, such as directing a firewall to block malicious content.

• Compliance with Regulations - Organizations use SIEM to meet compliance requirements by creating reports that address all logged security events among these sources. Without a SIEM, an association needs to manually recover log data and accumulate the reports.

• Incident Monitoring and  Handling - A SIEM improves incident management by allowing the security team to identify an attack's path across the network, identify compromised sources, and provide automated mechanisms to stop ongoing attacks.

Tactical cybersecurity isn't something you can stay competitive on at the moment. Maintaining this control over your network means being able to see the intrusions before they become an attack that could cost you money, downtime, brand reputation and customer trust--the things that will really cripple your company.

Conclusion

The truth is that the concept of SIEM is a very complicated one, filled with terms and security measures that can be intimidating to businesses without a significant amount of technical expertise. The best way to get your company up to speed with SIEM is to find an experienced information security consultant who can help you understand where to start and ensure that your business is taking the right steps towards becoming more secure in the digital world.
