The significance of proxy log investigation
Before diving into the anatomy of proxy logs, let us first provide an overview of the diverse range of cyber threats that can be effectively detected and investigated by leveraging proxy logs:
- Command-and-control communication: By examining proxy logs, SOC analysts can identify anomalous patterns of traffic, such as multiple connections to known malicious domains, unusual communication patterns, or unusual communication protocols. In the next chapter, we will deep dive into the aspects of C&C communication.
