Encoding - correct answer purpose is to transform data so that it can be represented in various formats and consumed by end systems. The goal is not to keep data secret, it's to ensure that it can be properly represented Encryption - correct answer Data transformation with the sole purpose of keeping the data secret. Number Systems (Base) - correct answer ...

Data - correct answer ---- can be any character, number, text, word, or binary representation but is lacking context. ----- that is given context and meaning then becomes information Information - correct answer Any communication or representation of knowledge.Such as facts, data, or opinions In any medium or form including but not limited to: textual, numerical, graphic, cartographic, narrative audi...

A technique that is based on how frequently certain letters appear in English versus others. Frequency Analysis 8-bit values, up to 256 characters ASCII 16-bit values, up to 65,536 UTF-16 ECB, CBC, CFB, OFB, and CTR. Common block cipher modes include: -Most basic, weak , and unsecure -Each block is processed separately -No Salt or IV is used and the same key will be used to encrypt each block. This means if a given plaintext is encrypted in ECB and results in a given ciphertext, th...

Which of the following are NOT operating modes of the DES encryption algorithm? A) CBC B) ECB C) CFB D) OFB E) CBE - Answer- e. DES has four modes of operations: CBC - Cipher Block Chaining. In CBC mode, each plaintext block is XORed with the previous cipher text block and then encrypted. ECB - Electronic Code Book. In ECB mode, each plaintext block is encrypted independently with the block cipher. CFB - Cipher Feedback. In CFB mode, the previous ciphe...

CISSP - EXAM PRACTICE/STUDY What is the most effective defense against cross-site scripting attacks? a) Limiting account privileges b)User Authentication c) Input validation d) Encryption - ANSWER c) Input validation prevents cross-site scripting attacks by limiting user input to a predefined range. This prevents the attacker from including the HTML ˂SCRIPT˃ tag in the input. What phase of the Electronic Discovery Reference Model puts evidence in a format that may be shared with...

Which attack is used to understand the type of network topology implemented at the target? - ANSWER Scanning The primary goal of a security awareness program is: - ANSWER To make everyone aware of potential risk and exposure Fault tolerance safeguards help us to combat threats to - ANSWER Data Reliability What is the term used to describe a component, which in case of failure automatically responds in way that causes no or minimum harm? - ANSWER Fail Safe Which one of the following i...
