TESTED AND CONFIRMED A+ ANSWERS

3DES - CORRECT ANSWER: DES used to encrypt each block three times , each with

a different key

Access Control List - CORRECT ANSWER: info about what kind of access certain

parties are allowed to have to a given system Read , write , execute

Access Control Models - CORRECT ANSWER: Discretionary ( DAC )

Mandatory ( MAC ) Rule - based Role - based ( RBAC ) Attribute - based ( ABAC )

Accountability - CORRECT ANSWER: Refers to making sure that a person is

responsible for their actions .-It provides us with the means to trace activities in our environment back to their source .-Depends on identification , authentication , and access control being present so that we can know who a given transaction is associated with , and what permissions were used to allow them to carry it out .

Acess Control - CORRECT ANSWER: Allowing - lets us give a particular party access to a given source Denying - opposite of gaining access Limiting - allowing some access to our resource , only up to a certain point Revoking - takes access away from former user

AES - CORRECT ANSWER: uses three different ciphers : one with a 128 - bit key , one with a 192 - bit key , and one with a 256 - bit key , all having a block length of 128 bits

Asymmetric cryptography - CORRECT ANSWER: a public key and a private key . The

public key is used to encrypt data sent from the sender to the receiver and is shared with everyone . Private keys are used to decrypt data that arrives at the receiving end and are very carefully guarded by the receive ( aka the public key cryptography )

Asymmetric Key Algorithms - CORRECT ANSWER: Secure Sockets Layer ( RSA )

Elliptic Curve Cryptography ( ECC ) Pretty Good Privacy ( PGP ) Transport Layer Security ( TLS )

Attack Types - CORRECT ANSWER: Interception

Interruption Modification Fabrication

Attack types and their effect - CORRECT ANSWER: Interception is the ONLY attack

that affects on confidentiality. Interruption, modification, and fabrication affects integrity and availability because most of the time they're impacting data.

Attribute - based ( ABAC ) - CORRECT ANSWER: based on attributes , such as of a

person , resource , or an environment

Auditing - CORRECT ANSWER: the examination and review of an organization's

records to ensure accountability through technical means .

Authentication - CORRECT ANSWER: verifying that a person is who they claim to be

Authorization - CORRECT ANSWER: what the user can access , modify , and delete

Availability - CORRECT ANSWER: For one's AUTHORIZED to ACCESS data when

needed

BinScope Binary Analyzer - CORRECT ANSWER: a tool developed by Microsoft to

examine source code for general good practices

Block Cipher - CORRECT ANSWER: takes a predetermined number of bits , known as

a block , in the plaintext message and encrypts that block

Brute Force - CORRECT ANSWER: an attack by submitting password attempts until

eventually guessed correctly

Buffer overflows - CORRECT ANSWER: a vulnerability that occurs when we do not

properly store the size of the data input into our applications , causing the program to crash and an attacker to take advantage

Certificates - CORRECT ANSWER: link a public key to a particular individual and are often used as a form of electronic identification for that particular person

Childrens ' Online Privacy Protection Act (COPPA) - CORRECT ANSWER: sets rules

on data collection for children under 13 to protect their online privacy

traffic that is flowing through them

Defense in-Depth - CORRECT ANSWER: using a variety of security measures that will still achieve a successful defense should one or more of the defensive measures fail

DES - CORRECT ANSWER: a block cipher based on symmetric key cryptography and

uses a 56 - bit key . Not that secured any more .

Detection and Analysis (Identification) - CORRECT ANSWER: detect the occurrence of an issue and decide whether or not it is actually an incident so that we can respond appropriately to it .

Digital Signatures - CORRECT ANSWER: ensure that the message was legitimately
