The CISO leads and oversees information security
The CISO’s role is based on good practice in the security industry and in governance. The role ensures that information security is managed at the senior executive level. Without a CISO, your organisation is unlikely to be able to effectively manage information security.
The CISO’s high-level responsibilities
Your CISO, if you have one, has the following high-level responsibilities.
Ensuring the flow of communication supports security objectives
Your CISO facilitates communication between security, ICT, and business personnel to ensure your organisation's security objectives are aligned.
This communication responsibility includes:
- interpreting information security concepts and language into business concepts and language
- ensuring that business teams consult with information security teams to determine appropriate security measures when planning new business projects.
Providing strategic guidance
Your CISO provides strategic guidance on information security. They’re responsible for:
- developing your organisation's information security programme at the strategic level
- overall management of information security within your organisation.
Ensuring your organisation complies with requirements
Your CISO ensures that your organisation complies with:
- national policy, standards, regulations, and legislation for information security
- internal policies and standards for information security.
Making sure training is implemented
Your CISO makes sure that an information security awareness and training programme is developed and maintained.
Lead information security personnel
- Oversee the management of information security personnel within your organisation.
Advising and coordinating
Your CISO is best placed to:
- advise ICT project leaders on the strategic direction of information security within your organisation
- provide a recommendation to the accreditation authority on whether to accept residual risks associated with the operation of your organisation’s systems
- coordinate the use of external information security resources to ensure that a consistent approach is applied across your organisation.
Your organisation’s responsibilities with the CISO role
Control your information security budget to ensure that your CISO has enough funding to support information security projects and initiatives.
Do not expect your CISO to necessarily be a technical expert on information security matters. Rather, expect they will use their knowledge of national and international standards and good practice to communicate with technical experts in your organisation.
Appointing a CISO
Your organisation should appoint a CISO or assign the role to someone who already works for your organisation.
The person you appoint to the CISO role should:
- be a member of your senior executive team or an equivalent management position (you don’t need to create a new dedicated position)
- be qualified and experienced enough to bring accountability and credibility to information security management
- report directly to the agency head on matters of information security within the organisation.
Before your CISO begins their role, your organisation must:
- clear them for access to all classified information processed in your organisation’s systems
- be able to brief them on any compartmented information in your organisation’s systems.
Managing conflicts of interest
If your CISO holds another role, such as also being your chief information officer (CIO) or a manager of a business unit, conflicts of interest might arise when operational imperatives conflict with security requirements. Good practice separates these roles.
When your CISO holds multiple roles, you should:
- clearly identify potential conflicts of interest
- implement a mechanism to allow independent decision making in areas where conflict may occur.
If your organisation outsources the CISO function, you should identify and carefully manage conflicts of interest, availability, and response times, so that your organisation is not disadvantaged. Be alert to possible conflicts of interest when the CISO deals with other vendors.
