What is a method that centralizes security information and event logs from various systems to facilitate attack detection?

1. Firewall

2. IDS

3. IPS

4. SIEM

The correct answer is: SIEM

The method that centralizes security information and event logs from various systems to facilitate attack detection is SIEM, which stands for Security Information and Event Management. SIEM solutions aggregate and analyze security data from a variety of sources such as servers, network devices, domain controllers, and more. This centralization allows for real-time monitoring, correlation of events, and identification of potential security incidents. By consolidating log data from multiple systems, SIEM tools help identify patterns indicative of security threats, enabling better detection and response capabilities. The analysis can reveal correlations that may not be apparent when looking at individual logs, making it a vital component in modern cybersecurity strategy for threat detection and incident response. In contrast, firewalls primarily focus on controlling incoming and outgoing network traffic based on predetermined security rules and do not centralize logging data. IDS (Intrusion Detection System) monitors network or system activities for malicious activities or policy violations but does not provide the comprehensive log aggregation and analysis that SIEM does. IPS (Intrusion Prevention System) takes a step further by not only detecting but also preventing detected threats; it may also log information, but still lacks the holistic view SIEM provides. Thus, SIEM is uniquely positioned to offer centralized event logging and security information management
