• the availability,
• the confidentiality,
• the integrity, and
• the traceability of information and data.

These four pillars constitute the foundations for the security requirements in the Federal Administration, together with

• the Federal ICT Strategy
• the misson statement of ICT security
• the Federal IT Ordinance (BinfV)
• the Federal Act on Data Protection
• and the Information Protection Ordinance (ISchV).

The most important requirements are set out in the Directive of the Federal Council on ICT Security in the Federal Administration (WisB).
