How do SIEM systems support NIS2 and ISO 27001 requirements?
The common purpose of standards
The standards that have appeared in the last few years, including NIS2 and ISO 27001, have the common goal of making IT systems more secure for organizations and minimizing cyber risks and attacks that can threaten the operations and reputation of organizations. Both approaches encourage organizations to manage information security in a comprehensive and systematic manner, ensuring adequate protection and continuous improvement in this area.
There are a number of extremely important areas where the organizations concerned may be lagging behind. Some shortcomings can be managed by developing and introducing processes, but there will also be some where the introduction of some new technology becomes necessary.
The SIEM System
Fortunately, there are technologies, such as a SIEM (Security Information and Event Management) system, which can help companies in not one but several important areas.
In short, a SIEM system is a technology that allows companies to collect, analyze and manage security events and log data from various sources in a central location. SIEM systems combine log management and real-time event analysis to provide a comprehensive view of the security status of networks and systems. These systems collect log files from various devices, such as firewalls, servers, other network devices and applications, then analyze these data to detect potential threats and unusual behaviors and send alerts to the IT security team.
How does it help you comply?
SIEM systems facilitate companies' risk analysis and threat detection, which is key to meeting the risk management requirements of NIS2. SIEM can identify potential threats, anomalies and suspicious activities and report them to your company's security team.
NIS2 requires companies to establish and use incident handling procedures. SIEM systems can automate incident detection, classification and response and help identify sources and resolve incidents.
SIEM systems automate the logging and archiving of security events, which are essential for generating compliance reports. NIS2 requires detailed reporting of security events and incidents, and SIEM systems greatly simplify this process.
What else does it provide beyond compliance?
In addition to the requirement systems, a SIEM system has many added values in increasing the general security level of the company.
SIEM systems collect all relevant security information centrally, making it easier for IT and IT security teams to identify potential threats and understand the context of events. Nowadays SIEM systems contain comprehensive AI solutions that can also help detect incidents for which, e.g. no specific detection rule has been developed.
Total visibility has three pillars.
- Endpoint protection information
- Network information
- Log information
Real-time monitoring and examining the three main pillars gives an organization the best chance of detecting and responding to potential threats, such as data breaches or unauthorized access attempts. A quick response can reduce potential damage and minimize negative impacts on business operations.
