To isolate the suspicious host that is performing intensive network scanning, the analyst should collect the traffic by most active source IP. This will help to identify the IP address of the host that is generating the most traffic and sending the most packets or bytes. The analyst can then apply filters or queries to analyze the traffic from that source IP anddetermine the nature and scope of the scanning activity. References := Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) - Cisco, page 72; [Cisco CyberOps Associate CBROPS 200-201 Official Cert Guide], page 468

 The regex [a−z]+ matches one or more lowercase letters from a to z. The plus sign (+) indicates that the preceding character set [a−z] can appear one or more times, thus matching strings of only lowercase letters1.

Defense-in-depth is a security strategy where multiple layers of defense are placed throughout an information technology (IT) system. It addresses physical, technical, and administrative controls to provide redundancy and ensure that if one layer fails, others will be in place to thwart an attack. References: Cisco Tech Roles - CyberOps Engineer

The “ps” command is used to display information about the processes running on a system. The “-ef” option shows the full format listing, which includes the process ID, the user, the CPU and memory usage, the command name, and other details. This can help the engineer identify which processes are consuming the most resources and causing the degraded performance of the server. The other options are either invalid or irrelevant, as they do not provide the necessary information or perform the required action. References := Cisco Cybersecurity

Cisco Application Visibility and Control (AVC) provides features like metrics collection and exporting (D) for visibility on TCP bandwidth usage, response time, and latency. Application recognition (E) combined with deep packet inspection helps in identifying unknown software by its network traffic flow. References := Cisco CyberOps Associate - Module 2: Security Concepts

A regular expression (regex) is a sequence of characters that defines a search pattern for text. A regex can be used to extract custom properties from log messages or events in a SIEM platform. In this case, the regex that matches the phrase “File: Clean” exactly is ^File: Clean$. The ^ symbol indicates the beginning of the line and the $ symbol indicates the end of the line. The regex ensures that no other characters are before or after the phrase. References:
