A forensic investigator started the process of gathering evidence on a laptop in response to an incident The investigator took a snapshof of the hard drive, copied relevant log files and then performed a memory dump Which of the following steps in the process should have occurred first?
The first step in forensic analysis is to collect the most volatile data, which is the information that would be lost when the power is turned off or the system is rebooted. This includes the contents of memory (RAM) and other temporary data that are stored in caches or buffers. A memory dump captures this data and should be done before other less volatile data is collected, like hard drive images or log files, to ensure the most accurate and comprehensive capture of the system's state at the time of the incident.
in a situation where the cost of anti-malware exceeds the potential loss from a malware threat, which of the following is the most cost-effective risk response?
Risk acceptance is the decision to accept the potential risk and continue operating without engaging in extraordinary measures to mitigate it. If the cost of anti-malware exceeds the potential loss from a malware threat, it would be more cost-effective to accept the risk rather than spend more on mitigations that don't provide proportional value. This is part of a cost-benefit analysis in risk management.
A security engineer is assessing the security controls of loT systems that are no longer supported for updates and patching. Which of the following is the best mitigation for defending these loT systems?
Network segmentation is a method to isolate environments from one another, thus limiting the scope of a potential attack. For IoT systems that cannot be updated or patched, network segmentation is the best mitigation technique. It would contain any compromise to the segmented network and prevent it from affecting the rest of the network infrastructure.
A company with only U S -based customers wants to allow developers from another country to work on the company's website However, the company plans to block normal internet traffic from the other country Which of the following strategies should the company use to accomplish this objective? (Select two).
Having developers use the company's VPN can provide them with secure access to the network while still allowing the company to block normal internet traffic from the other country. A jump box serves as a secure entry point for administrators or in this case, developers, to connect before launching any administrative tasks or accessing further areas of the network. This setup maintains security while still providing necessary access.
A forensics investigator is analyzing an executable file extracted from storage media that was submitted (or evidence The investigator must use a tool that can identify whether the executable has indicators, which may point to the creator of the file Which of the following should the investigator use while preserving evidence integrity?
ssdeep is a tool that computes and matches Context Triggered Piecewise Hashing (CTPH), also known as fuzzy hashing. It can be used to identify similar files or slight variations of the same file, which may point to the creator of the file if certain patterns or markers are consistently present. This method allows for integrity checking without altering the evidence, which is critical in forensic investigation.
