Summary
In this chapter, you explored a comprehensive range of IOCs that it is essential to understand to detect potential malicious activity. You learned about network-related indicators such as bandwidth consumption, beaconing, and rogue devices. A key takeaway from this chapter is understanding the importance of establishing baselines for normal network behavior, allowing deviations to be quickly identified and investigated. Host IOCs were discussed, including processor and memory consumption, unauthorized software, and data exfiltration. Detecting these indicators requires log analysis to uncover attack patterns and track unauthorized changes across endpoints. Application-related indicators such as anomalous activity, unexpected outbound communication, and application logs were covered. Correlating multiple IOCs results in a more comprehensive security assessment and allows the detection of sophisticated attacks that might otherwise go unnoticed. Additionally, you reviewed social...
