Protect the SEP agent from being disabled by malicious software. Conclusion
Additionally, this build refines the implementation of SONAR, Symantec’s behavior-based protection engine. SONAR creates a virtual environment (sandboxing) to analyze the behavior of unknown processes. In version 14.3, the heuristics have been tuned to reduce false positives—a persistent challenge in behavioral analysis—while maintaining high detection rates for polymorphic malware.
