What are the key principles of information security, and how can they be applied to protect sensitive data and information systems from threats and vulnerabilities?
The following is a list of basic information security principles:
1. Data Ownership - Information should not flow freely across organizational boundaries without proper authorization or consent.
2. Confidentiality - Information should only be shared with those who need it for their job functions. This includes keeping sensitive data secure in storage and transmission.
3. Integrity - All actions taken on behalf of an organization must follow established procedures and maintain accuracy at all times.
4. Availability - Systems and data must always be available when needed by authorized users. Failures should be minimized through redundant hardware and backup strategies.
5. Privacy - Sensitive personal information should never be shared indiscriminately outside organizations. Personal identifiers should be properly redacted before being made public.
