PHI stands for protected health information, which is any information that relates to the health or health care of an individual and can be used to identify that person. PHI is regulated by the Health Insurance Portability and Accountability Act of 1996 (HIPAA), which sets national standards for the privacy and security of health information. HIPAA requires covered entities, such as health care providers, health plans, and health care clearinghouses, to notify individuals and regulatory agencies of any breach of unsecured PHI. A breach is defined as the unauthorized acquisition, access, use, or disclosure of PHI that compromises the privacy or security of the information

A hash is a mathematical function that produces a unique value for a given input. A hash can be used to verify that a bit-level image copy of a hard drive is an exact clone of the original hard drive by comparing the hash values of both drives. If the hash values match, then the drives are identical. If the hash values differ, then there is some discrepancy between the drives. Inserting the hard drive on a test computer and booting the computer, recording the serial numbers of both hard drives, or comparing the file-directory listing of both hard drives are not reliable methods to verify that a bit-level image copy of a hard drive is an exact clone of the original hard drive.

The suspicious event was able to accomplish establishing persistence by creating a registry change that runs a command shell process every time a user logs on. The registry change modifies the Userinit value under the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon key, which specifies what programs should run when a user logs on to Windows. By appending “cmd.exe,” to the existing value, the event ensures that a command shell process will be launched every time a user logs on, which can allow the attacker to maintain access to the system or execute malicious commands. The other options are not related to the registry change. References: CompTIA Cybersecurity Analyst (CySA+) Certification Exam Objectives (CS0-002), page 10;

Memory cache and swap volume are types of media that are most volatile and should be preserved during a digital forensics investigation. Volatile media are those that store data temporarily and lose their contents when the power is turned off or interrupted. Memory cache is a small and fast memory that stores frequently used data or instructions for faster access by the processor. Swap volume is a part of the hard disk that is used as an extension of the memory when the memory is full or low .
