What tools can monitor security breaches and suspicious activity in real-time?
Security Information and Event Management (SIEM) Tools
- SIEM tools collect and analyze log data from servers, applications, firewalls, and network devices.
- They provide real-time alerts for unusual or malicious activity across the infrastructure.
- Popular SIEM solutions include Splunk, IBM QRadar, and LogRhythm.
- These tools support threat detection, compliance reporting, and forensic investigation.
- Advanced SIEMs use machine learning to detect zero-day attacks and behavioral anomalies.
Intrusion Detection and Prevention Systems (IDPS)
- IDPS tools detect unauthorized access or attack attempts on networks and systems.
- They analyze traffic patterns to flag unusual spikes, port scans, or injection attacks.
- Tools like Snort, Suricata, and OSSEC offer both host-based and network-based protection.
- Prevention features can automatically block suspicious IPs or requests in real-time.
- Regular updates help these tools adapt to evolving threats.
Endpoint Detection and Response (EDR) Tools
- EDR solutions monitor endpoints such as laptops, desktops, and servers for real-time threats.
- They provide deep visibility into file behavior, user activity, and memory usage.
- Examples include CrowdStrike Falcon, Microsoft Defender for Endpoint, and SentinelOne.
- EDR tools can isolate infected devices from the network to prevent lateral spread.
- They often include incident response and rollback features.
Web Application Firewalls (WAF)
- WAFs protect websites from malicious HTTP traffic, including SQL injection and XSS.
- Tools like Cloudflare WAF, AWS WAF, and Imperva monitor and filter web requests in real time.
- They can block or challenge suspicious traffic based on customizable rules.
- WAFs provide dashboards and alerts for attack attempts or abnormal behavior.
- Integration with CDN and load balancers enhances performance and coverage.
User Behavior Analytics (UBA) and Anomaly Detection Tools
- UBA tools track normal user behavior and alert on deviations like unusual login times or data downloads.
- They are useful in detecting insider threats or compromised accounts.
- Tools like Exabeam, Varonis, and Splunk UBA combine behavioral modeling with threat intelligence.
- Real-time dashboards visualize risk scores and suspicious patterns.
- These systems reduce false positives by learning baseline user behavior over time.
