Detailed Explanation:Behavioral analytics tools monitor user actions and detect anomalies that may indicate insider threats, such as unauthorized access or unusual data exfiltration activities. These tools establish baselines for normal behavior and flag deviations. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 4: Security Operations, Section: "Behavioral Analytics and Monitoring".

To analyze malware behavior in detail, the best approach is toexecute the malware in a sandbox (D) andcapture its network activity. This providesreal-time analysisof how the malware behaves, spreads, and communicates.
This method is highlighted inDomain 2.1under"Analyzing indicators of compromise"and usingsandboxing and packet captureto study malware.

= A change control request is a document that describes the proposed change to a system, the reason for the change, the expected impact, the approval process, the testing plan, the implementation plan, the rollback plan, and the communication plan. A change control request is a best practice for applying any patch to a production system, especially a high-priority one, as it ensures that the change is authorized, documented, tested, and communicated. A change control request also minimizes the risk of unintended consequences, such as system downtime, data loss, or security breaches.

Code signing (D)usescryptographic digital signaturesto confirm theintegrity and authenticityof software code.
It ensures that the code hasnot been alteredafter being signed, providing assurance that the application is trustworthy.
This aligns withCompTIA Security+ SY0-701 Domain 2.3: Application security techniques, which includescode signingas a method to validatecode integrity.
