5.2 Information Security Roles and Responsibilities

Information security roles and responsibilities should be defined and allocated according to the organisation needs.

In the context of information security, roles and responsibilities refer to the specific tasks and duties that individuals or groups within an organisation are assigned in order to ensure the security and protection of information assets. These roles and responsibilities may vary depending on the size and structure of the organisation, as well as the specific security needs and requirements of the organisation.

It is important for an organisation to clearly define and communicate the roles and responsibilities of all individuals and groups involved in maintaining the security of its information assets. This helps to ensure that there is a clear chain of responsibility and that everyone understands their role in protecting sensitive information.Some common information security roles and responsibilities include:

• Chief Information Security Officer (CISO): The CISO is responsible for overall information security strategy, policy, and day-to-day management of the organisation's information security program.
• Information security team: This team is responsible for implementing and maintaining the organisation's information security controls, such as firewalls, intrusion detection systems, and access controls.
• System administrators: These individuals are responsible for maintaining the security of the organisation's systems and networks, including patching and updating systems and applications.
• Network administrators: These individuals are responsible for managing the organisation's network infrastructure, including routers, switches, and other networking equipment.
• End users: All employees within an organisation are responsible for adhering to the organisation's information security policies and practices and reporting any security incidents or concerns to the appropriate personnel.
