• A greylist in endpoint applications refers to a list of items that are not yet classified as either good (whitelisted) or bad (blacklisted).
• The primary function of a greylist is to hold applications, processes, or files that are under observation due to their unknown status.
• These items are neither trusted nor immediately flagged as harmful, allowing security teams to monitor them closely for any suspicious behavior.
• By placing items on a greylist, security operations can prevent potential threats without disrupting legitimate processes, awaiting further analysis to determine their true nature.

Port scanning is a technique that an attacker uses to discover which network ports are open, closed, or filtered on a target device. By sending packets to different ports and observing the responses, an attacker can identify the services and applications running on the device, as well as potential vulnerabilities that can be exploited. Port scanning is a common reconnaissance activity that precedes an attack. References: Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) - Cisco, page 2-6; 200-201 CBROPS - Cisco, exam topic 1.1.a

 During the collection phase of the forensic process, data related to a specific event is labeled and recorded to preserve its integrity. This step ensures that the data remains unaltered and authentic from the time of collection until it is presented as evidence, maintaining the chain of custody. References := Cisco Cybersecurity Operations Fundamentals - Module 6: Security Incident Investigations
