CompTIA CS0-002 Exam With Confidence Using Practice Dumps

The security incident response process is a set of procedures and guidelines that define how to identify, contain, analyze, and recover from security incidents that compromise the confidentiality, integrity, or availability of an organization’s assets or operations. Initiating the security incident response process for unauthorized access is the first and most appropriate action that the analyst should take, as it would allow the analyst to follow a structured and consistent approach to handle the situation and mitigate the impact of the incident1.

Documenting the chain of custody is an important step in the forensic analysis of any device, as it helps to ensure that all evidence is collected and preserved correctly. A memory dump is also essential, as it can provide information about the state of the device when the attack occurred and can be used for further analysis.

Documenting the respective chain of custody can help to preserve the integrity and admissibility of the evidence collected from the mobile device during the forensic analysis. Chain of custody is a record of who handled, accessed or modified the evidence, when, where, how and why . Performing a memory dump of the mobile device for analysis can help to extract volatile data from the mobile device that may contain valuable information about the ransomware attack, such as processes, network connections or encryption keys. Memory dump is a process of copying the contents of the memory (RAM) to a file or storage device .

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.
