Sanitizing the workstation and verifying countermeasures are restored are part of the eradication and recovery processes that the security analyst should perform next. Eradication is the process of removing malware or other threats from the affected systems, while recovery is the process of restoring normal operations and functionality to the affected systems. Sanitizing the workstation can involve deleting or wiping any malicious files or programs, while verifying countermeasures are restored can involve checking and updating any security controls or settings that may have been compromised .

Sinkholing is a technique for manipulating data flow in a network; you redirect traffic from its intended destination to a server of your choosing. It can be used maliciously, to steer legitimate traffic away from its intended recipient, but security professionals more commonly use sinkholing as a tool for research and reacting to attacks1.

For example, sinkholing can be used to redirect traffic from a botnet or a malware-infected host to a server under the control of the defender, where the traffic can be analyzed, blocked, or neutralized. This can help identify and isolate compromised devices, prevent command-and-control communication, and disrupt malicious activities2.

The other options are not the best solutions for the following reasons:

• Blocklisting is a technique for preventing access to or communication with certain IP addresses, domains, or applications that are known or suspected to be malicious. Blocklisting can be implemented using firewalls, routers, proxies, or software tools. Blocklisting can protect a network from unwanted or harmful traffic, but it does not redirect the traffic to a different destination.
• Geoblocking is a technique for restricting access to or communication with certain IP addresses, domains, or applications based on their geographic location. Geoblocking can be implemented using firewalls, routers, proxies, or software tools. Geoblocking can protect a network from unauthorized or undesirable traffic from specific regions or countries, but it does not redirect the traffic to a different destination.
• Sandboxing is a technique for isolating and executing potentially malicious code or applications in a separate and secure environment. Sandboxing can be implemented using virtual machines, containers, or software tools. Sandboxing can protect a network from malware infection or damage, but it does not redirect the network traffic to a different destination.

Resource exhaustion occurs when a system runs out of resources such as memory, CPU, disk space, or network bandwidth due to excessive demand or poor management1. In this case, the server statistics show that the CPU usage is 100%, the memory usage is 99%, and the disk usage is 98%, indicating that the system is suffering from resource exhaustion. This can affect the performance and availability of the system and its applications. A race condition (A) is a condition where the system’s behavior depends on the sequence or timing of other uncontrollable events2. Privilege escalation (B) is a situation where an attacker gains unauthorized access to higher privileges or permissions on a system3. VM escape (D) is a technique where an attacker breaks out of a virtual machine and interacts with the host operating system.
