ITSS 4370 FINAL EXAM PART 2 QUESTIONS AND ANSWERS
What is a virus in the context of cybersecurity? - CORRECT ANSWER✅✅A piece of code capable of
copying itself, typically causing damage such as corrupting the system or destroying data.
What is a Boot Sector virus? - CORRECT ANSWER✅✅A virus that damages or controls the boot sector
on the drive, rendering the machine unusable.
What does a Browser Hijacker do? - CORRECT ANSWER✅✅It hijacks browser favorites, home page URL,
and search preferences, redirecting to a malicious site.
What is a Resident virus? - CORRECT ANSWER✅✅A virus that accesses computer memory and remains
dormant until a payload is delivered.
What is a Direct Action virus? - CORRECT ANSWER✅✅A seemingly harmless file attached with malicious
code that delivers a payload immediately.
What is a Polymorphic virus? - CORRECT ANSWER✅✅A self-encrypted virus designed to avoid detection
by a scanner.
What is a File Infector virus? - CORRECT ANSWER✅✅A virus used to inject malicious code into critical
files that run the operating system or important programs.
What is a Multipartite virus? - CORRECT ANSWER✅✅A virus that propagates over a network by copying
itself or injecting code into critical computer resources.
What is a Macro virus? - CORRECT ANSWER✅✅A virus that delivers a payload when a file is opened and
a macro runs.
What are forces of nature in cybersecurity? - CORRECT ANSWER✅✅Natural events that disrupt data
storage, transmission, and use of information, such as tornadoes, floods, earthquakes, and fires.
, What is a safeguard against forces of nature? - CORRECT ANSWER✅✅Disaster Recovery (DR) and
Business Continuity (BC) planning along with redundant facilities.
What are common causes of human error in data security? - CORRECT ANSWER✅✅Inexperience,
improper training, and incorrect assumptions.
What are potential consequences of human error? - CORRECT ANSWER✅✅Release of confidential data,
entry of erroneous data, accidental data deletion or modification, and failure to protect information.
What is multifactor authentication (MFA)? - CORRECT ANSWER✅✅An electronic authentication
method requiring two or more pieces of evidence to grant access to a website or application.
What are the three factors of MFA? - CORRECT ANSWER✅✅Knowledge (something the user knows),
Possession (something the user has), and Inherence (something the user is).
What is encryption? - CORRECT ANSWER✅✅The process of converting human-readable plaintext into
incomprehensible ciphertext.
Block Cipher - CORRECT ANSWER✅✅A method of encrypting data in fixed-size chunks (blocks) of bits,
rather than bit by bit, consists of two algorithms, one for encryption and the other for decryption. The
decryption algorithm is defined as the inverse function of encryption.
Block ciphers use a combination of - CORRECT ANSWER✅✅- substitution = substitute one character or
value for another
- permutation = a reversible transposition of characters or values
What is the difference between symmetric and asymmetric encryption? - CORRECT
ANSWER✅✅Symmetric encryption uses a single secret key, while asymmetric encryption uses a public
key for encryption and a private key for decryption.
Data encrypted at rest - CORRECT ANSWER✅✅a stored file is encrypted
