What Makes A Good SIEM?
A security information and event management (SIEM) solution keeps track of logs and events related to network activity, endpoint security, servers, and applications. It records data points from every device, application, server, cloud service, and user that interacts with the network.
Analytics: Knowing where problems occur and getting insight into why they occur is key when building defenses against attacks. Analytics can happen within the SIEM system itself or through third party solutions. Either way, analytics must be available and accessible to users.
Alerting: Alerting is one of the most important functions for any SIEM solution. Users should receive alerts whenever a threat is detected or suspicious behavior occurs. An alert can range from a single notification of “suspicious traffic” to a full blown attack.
Reporting: Reporting is important because it gives users insights into everything that happened during an incident. Reports can be generated by the SIEM system itself, or through third parties.
Security operations: Security operations is the process of managing incidents and responding to threats. Security operations includes monitoring logs, analyzing reports, and responding to threats.
What makes a good SIEM Solution?
An effective SIEM solution provides comprehensive logging and analysis capabilities. It is built around a central database and can store logs from various sources like network devices, endpoints, servers, and software. Logs from each source are stored separately in the database, making them easily searchable and analyzeable.
The SIEM solution should provide both real-time analysis and historical reporting. Real-time analysis means that events are analyzed immediately after they occur. Historical reporting lets you see trends over time. Both real-time and historical analysis needs to be easily accessible and viewable by all users.
Logging: The ability to log events is critical for understanding what is happening on the network. Logs can come from various types of devices like routers, firewalls, VPN concentrators, switches, and other devices. Logs include data such as protocols used, file names, locations, dates, times, and more.
Analysis: Once logs are collected, it’s important to understand how these logs relate to each other. Analysis tools can help users correlate logged events and determine if there is anything suspicious going on.
What Is SIEM Software Security information and event management (SIEM) is a technology that collects and analyzes security-related events from various sources. It helps IT administrators find the root cause of a security breach.
