FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Risk is defined as the potential for loss or damage when a threat exploits a vulnerability.

Detailed explanation-2: -Risk is the likelihood of a threat agent taking advantage of vulnerability and the corresponding business impact. Reducing vulnerability and/or threat reduces the risk. E.g.: If a firewall has several ports open, there is a higher likelihood that an intruder will use one to access the network in an unauthorized method.

Detailed explanation-3: -A vulnerability is a weakness that can be exploited by cybercriminals to gain unauthorized access to a computer system. After exploiting a vulnerability, a cyberattack can run malicious code, install malware, and even steal sensitive data.

Detailed explanation-4: -In computer security a threat is a possible danger that might exploit a vulnerability to breach security and thus cause possible harm. A vulnerability is a weakness which allows an attacker to reduce a system’s information assurance.

Detailed explanation-5: -An exploit is a code that takes advantage of a software vulnerability or security flaw. It is written either by security researchers as a proof-of-concept threat or by malicious actors for use in their operations.
