Information security programmes rarely fail because policies are missing.
They fail because management behaviour does not match stated intent.
Annex A 5.4 exists to close that gap.
This control focuses on ensuring that management actively supports, enforces, and demonstrates commitment to information security, rather than delegating it entirely to technical teams or treating it as a compliance exercise.
Security culture starts with leadership behaviour.
Annex A 5.4 makes that explicit.

Annex A 5.4 of ISO 27001:2022 addresses management responsibilities for information security.
At a practical level, this means:
The control is not about micromanaging security or turning managers into security specialists. It is about visible ownership and support.
When management treats security seriously, the organisation tends to follow. When it doesn’t, controls are bypassed quietly.
Annex A 5.4 ensures that information security is embedded into how the organisation is managed, not bolted on.
Management influence behaviour in ways policies cannot. People take cues from:
If management bypasses security controls, others will follow. If management treats security as optional or inconvenient, security becomes optional.
This control reinforces that information security is a management responsibility, not just a technical one.
A pragmatic approach to Annex A 5.4 usually includes the following elements.
Managers should have a clear understanding of:
This does not require deep technical knowledge, but it does require awareness and accountability.
People should understand their security responsibilities before they are given access to systems or information.
This typically includes:
Setting expectations early reduces friction later.
Management behaviour sets the tone.
Examples include:
These actions carry far more weight than policy statements.
Security often fails when it competes with delivery without management support.
This control recognises the need for:
Without this support, security becomes a shortcut casualty.
People need to feel able to raise security concerns without fear of negative consequences.
Management support for:
is a critical part of maintaining a healthy security culture.
These challenges are usually governance issues, not technical ones.
Annex A 5.4 is about leadership, not control frameworks.
When management:
security becomes part of normal operations.
If management disengages, no amount of documentation will compensate.
Strong security culture starts at the top — Annex A 5.4 exists to make that unavoidable.
