WGU D432 – DIGITAL FORENSICS IN CYBERSECURITY ACTUAL REAL EXAM CORRECT QUESTIONS AND ANSWERS 2024.

American Standard Code for Information Interchange (ASCII) - ANSWER A set of codes defining all the various keystrokes you could make, including letters, numbers, characters, and even the spacebar and return keys. Anonymous remailing - ANSWER The process of sending an email message to an anonymizer. The anonymizer strips identifying information from an email message before forwarding it with the anonymous mailing computer's IP address. Anti-forensics - ANSWER The actions that perpetrators take to conceal their locations, activities, or identities. Asymmetric cryptography - ANSWER Cryptography wherein two keys are used: one to encrypt the message and another to decrypt it. Asynchronous transfer mode (ATM) - ANSWER A high-speed connection technology that uses fixed-length, 53-byte packets called calls. Authenticate - ANSWER To verify the identity of a person, or to verify evidence. Base transceiver station (BTS) - ANSWER The part of the cell network responsible for communications between the mobile phone and the network switching system. Basic input/output system (BIOS) - ANSWER The basic instructions stored on a chip for booting up the computer. Bit-level information - ANSWER Information at the level of actual 1s and 0s stored in memory or on the storage device. Block cipher - ANSWER A form of cryptography that encrypts data in blocks; 64-bit blocks are quite common, although some algorithms (like AES) use larger blocks. Bootstrap environment - ANSWER A special program, such as U-Boot or RedBoot, that is stored in a special section of the flash memory. Brute-force attack - ANSWER An attack in which the attacker tries to decrypt a message by simply applying every possible key in the keyspace. Business continuity plan (BCP) - ANSWER A plan for maintaining minimal operations until the business can return to full normal operations. Business impact analysis (BIA) - ANSWER An analysis of how specific incidents might impact the business operations. Caesar cipher - ANSWER The method of cryptography in which someone chooses a number by which to shift each letter of a text in the alphabet and substitute the new letter for the letter being encrypted. This is also known as a monoalphabet, singlealphabet, or substitution cipher. Carrier - ANSWER The signal, stream, or data file in which the payload is hidden. Cell-phone forensics - ANSWER The process of searching the contents of cell phones. Chain of custody - ANSWER The continuity of control of evidence that makes it possible to account for all that has happened to evidence between its original collection and its appearance in court, preferably unaltered. Channel - ANSWER The type of medium used to hide data in steganography. This may be photos, video, sound files, or Voice over IP. Clean room - ANSWER An environment that has a controlled level of contamination, such as from dust, microbes, and other particles. Cloud computing - ANSWER The practice of delivering hosted services over the internet. This can be software as a service, platform as a service, or infrastructure as a service. Computer forensics - ANSWER The use of analytical and investigative techniques to identify, collect, examine, and preserve computer-based material for presentation as evidence in a court of law. Consistency checking - ANSWER A technique for file system repair that involves scanning a disk's logical structure and ensuring that it is consistent with its specification. Cryptanalysis - ANSWER A method of using techniques other than brute force to derive a cryptographic key. Curriculum vitae (CV) - ANSWER An extensive document expounding one's experience and qualifications for a position, similar to a résumé but with more detail. In academia and expert work, it is usually used rather than a résumé. Cyberstalking - ANSWER The use of electronic communications to harass or threaten another person. Data consistency - ANSWER The act of ensuring the data that is extracted is consistent. Daubert standard - ANSWER The standard holding that only methods and tools widely accepted in the scientific community can be used in court. Demonstrative evidence - ANSWER Information that helps explain other evidence. An example is a chart that explains a technical concept to the judge and jury. Denial-of-service (DoS) attack - ANSWER An attack designed to overwhelm the target system so it can no longer reply to legitimate requests for connection. Digital evidence - ANSWER Information that has been processed and assembled so that it is relevant to an investigation and supports a specific finding or determination.
