What are the six security services?

The six key security services are: Confidentiality: Ensures that information is accessible only to those authorized to view it, protecting sensitive data from unauthorized access. Integrity: Maintains the accuracy and completeness of data, ensuring it is not altered or tampered with by unauthorized individuals. Authentication: Verifies the identities of users and devices, ensuring that only legitimate parties can access systems and data. Authorization: Grants or denies permissions based on the identity and role of the user, ensuring access control. Non-repudiation: Guarantees that a party cannot deny the authenticity of their signature on a document or a sent message. Availability: Ensures that information and resources are accessible to authorized users when needed, preventing disruptions and downtime.
