How is Siem implemented?
7 SIEM Best Practices- Determine Scope. Start by determining the scope of your SIEM implementation.
- Tweak Correlation Rules.
- Identify Compliance Requirements.
- Monitor Access to Critical Resources.
- Defend Your Network Boundaries.

WHY is Siem important?
Companies use SIEM to protect their most sensitive data and to establish proof that they are doing so, which allows them to meet compliance requirements. A single SIEM server receives log data from many sources and can generate one report that addresses all of the relevant logged security events among these sources.What makes a SIEM so powerful on a network?
By correlating process activity and network connections from host machines a SIEM can detect attacks, without ever having to inspect packets or payloads. While IDS/IPS and AV do what they do well, a SIEM provides a safety net that can catch malicious activities that slip through traditional defenses.What does Siem stand for?
