QUESTIONS WITH CORRECT
ANSWERS GRADED A+
◍ Triple Data Encryption Standard (3DES).
Answer: _____ has a block size of 64 bits, key size of 112 bits, and 48
rounds of substitution & transposition.A. DESB. RSAC. 3DES
◍ Character Representation.
Answer: ASCII and Unicode
◍ The Counter (CTR) block cipher mode converts the block cipher into a
stream cipher..
Answer: True
◍ asymmetric key pair.
Answer: An entity seeking to obtain a digital certificate must first generate a
_____ for themselves.A. secret keyB. asymmetric key pairC. registration
authority
◍ Digital Millennium Copyright Act (DMCA).
Answer: A United States copyright law created to prosecute the production
and dissemination of technology, devices, or services that control access to
copyrighted works.
◍ Cold Site.
Answer: Physical location like a shell that can be used for operations should
the need arise; not equipped with hardware, servers, etc.; cheaper to have
◍ SOX (Sarbanes-Oxley Act).
Answer: this law regulates the financial practice and governance of
corporations
,◍ Brute Force.
Answer: The process of using all possible combinations of letters and
numbers to crack a password.
◍ RC5.
Answer: _____ is a symmetric block cipher that uses block sizes of 32, 64,
or 128 bits and boasts a variable key size up to 2048 bits.A. RC2B. RC4C.
RC5
◍ Packet Switched Data Networks (PSDN).
Answer: The standard for current telecommunication networks.
◍ How many rounds does AES use?.
Answer: 10, 12, or 14
◍ Polyalphabetic cipher that involves using a different mapping, based on a
keyword, for each character of the cipher. An advantage of this type of
cipher is that the same plaintext character is likely to be coded to different
mappings, depending on the position of the keyword, making guessing more
difficult..
Answer: VIGENERE
◍ OTP.
Answer: _____ allow for a new unique passcode to be created for each
instance based on an initial seed.A. One Time Passwords (OTP)B. Hashed
One Time Passwords (HOTP)C. Timed One Time Password (TOTP)
◍ system bus.
Answer: connection between the CPU, memory, storage, expansion slots,
and other motherboard components
◍ Bus.
Answer: Permits information to move between each component; electrical
channels that enable communication among the electronic components
◍ Unicode.
Answer: Defines the internal text coding system in nearly all operating
, systems; assigns each character a unique number.
◍ RBAC (Role Based Access Control).
Answer: access is based on the role the individual is performing - similar to
MAC in that access controls are set by an authority responsible for doing so,
rather than by the owner of the resource
◍ Where the intruder inserts or modifies messages..
Answer: Active attack.
◍ Direct Move.
Answer: Data that does not need to be transformed being transferred to a
data warehouse.
◍ Preliminary investigation.
Answer: Assesses the feasibility of the proposed project and selects a
development methodology
◍ CLEFIA.
Answer: Block size 128 key size 128, 192, 256LIGHTWEIGHT
SYMMETRIC BLOCK
◍ rewards.
Answer: Regarding blockchain, miners receive _____ for successful mining
efforts.A. penaltiesB. rewardsC. contracts
◍ pretexting.
Answer: A technique involving a fake identity & a believable scenario that
elicits the target to give out sensitive information or perform some action
which they would not normally do for a stranger
◍ circumvention.
Answer: Describes the ease with which a system can be tricked by a falsified
biometric identifier
◍ 5 steps of the operations security process.
Answer: 1.Identification of critical information2.Analysis of
threats3.Analysis of vulnerabilities4.Assessment of risks5.Application of
