When using a newly implemented security information and event management (SIEM) infrastructure, the first thing that should be considered is tuning.
Tuning refers to the process of configuring the SIEM system to filter out unnecessary or irrelevant events and to prioritize those that are most important to the organization's security. This is important because SIEM systems can generate a large volume of alerts, and not all of them will be relevant to the organization's security posture. By tuning the system, the organization can ensure that it is focusing on the events that matter most and that it is not being overwhelmed with alerts that do not require immediate attention.
Once the system has been properly tuned, the organization can then consider other factors, such as report distribution, encryption, and retention. Report distribution refers to the process of disseminating information about security events to relevant stakeholders within the organization. Encryption refers to the process of encrypting data in transit or at rest to protect it from unauthorized access. Retention refers to the length of time that security event data is retained within the SIEM system.
While all of these factors are important considerations for a SIEM implementation, they are secondary to tuning. Without proper tuning, the organization may be inundated with alerts that are not relevant to its security posture, which can lead to alert fatigue and a lack of attention to truly important security events. Therefore, it is important to prioritize tuning as the first consideration when implementing a new SIEM infrastructure.
