FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Countermeasures (sometimes referred to as measures) is a term used to describe anything in risk management (management standards, revised process, technical means) which is proposed in order to reduce threats and vulnerabilities, and thus reduce future risk.

Detailed explanation-2: -Definition(s): Actions, devices, procedures, techniques, or other measures that reduce the vulnerability of an information system. Protective measures prescribed to meet the security requirements (i.e., confidentiality, integrity, and availability) specified for an information system.

Detailed explanation-3: -Countermeasures can include any process that serves to reduce threats or vulnerabilities. While it may be nice to think that this process must only be done once that is not the case. Risk management should be a continuous process that is repeated when there are changes to the environment or on a periodic basis.

Detailed explanation-4: -Countermeasures target a risk’s threat, vulnerability, or both. Countermeasures also have a level of effectiveness. This effectiveness level determines how much the countermeasure reduces the likelihood of the associated threat, or severity of the associated vulnerability.

Detailed explanation-5: -These three categories are proactive countermeasures, dynamic countermeasures and reactive countermeasures.
