Information security is an essential aspect of information technology. It ensures that information is protected and that information systems are secure from threats such as unauthorized access, destruction, disruption, or modification. Information security responsibilities can be assigned to different people in the organization depending on their role and expertise.
– The chief information officer (CIO) has overall responsibility for information security at an organization. This person typically oversees all IT operations, including developing policies related to information protection and specific activities like information system monitoring, training staff in data protection procedures, managing risk assessments, audits, etc.
A senior executive may be responsible for developing a strategy to comply with legislative requirements relating to information safety, including assessing risks associated with new technologies entering the organization.
– One information security responsibility is to implement appropriate information technology controls in data systems, software applications, and networks across the business units of an organization. This will involve developing policies for access control lists (ACLs), configuration settings on servers, etc., performing risk assessments using available methodologies like information system mapping tools to identify potential vulnerabilities, assessing information security policies and procedures, etc.
– Another responsibility is to investigate incidents that have been reported by other departments or business units of the organization, determine root cause(s) for a given incident, propose corrective actions and communicate these back within an appropriate time frame.
Information security professionals are essential to an organization because they help protect information assets.
