When creating a security program, which approach would be used if senior management is supporting and enforcing the security policy?

A bottom-up approach is the opposite model, where IT or technical staff try to establish security practices without formal senior management mandate or organizational authority.

In a top-down security approach, executive or senior management drives the creation and formal enforcement of security policies, supplying the budget, authority, and consequences necessary for organization-wide compliance. This is the preferred model because management commitment ensures policies carry weight across all departments, not just IT. It stands in direct contrast to a bottom-up approach, where technical staff attempt to enforce security without formal executive backing.

'Senior creation approach' is not a recognized term in any security program management framework or certification domain.

'IT assurance approach' is not a standard security governance term and does not describe a management-driven enforcement model.
