Why is information security awareness important?

Effective security awareness training helps employees understand proper cyber hygiene, the security risks associated with their actions and to identify cyber attacks they may encounter via email and the web.

What are the impacts of data quality safety and encryption?

Whenever data is encrypted, it reduces the potential value of the data. When the value is reduced, the likelihood of a thief taking the data is diminished; that is called risk mitigation.

What is the relationship between information security and physical security?

Information security also includes establishing a thorough, physical security system as well. The goal of a physical security management system, in terms of information management security, is to prevent unauthorised physical access, damage and interference to an organisation’s premises and information.
