Responsible for designing appropriate technical and organizational measures in order to ensure the confidentiality, integrity, security, and availability of an organization's assets, information, data, and services. Below are the objectives and short descriptions of those sub-processes, followed by a diagram illustrating the ITIL Information Security Management Process Flow: 1) Design of Security Controls: ITIL Information Security Management Sub-Process:Īccording to ITIL V3, ISM has four sub-process. These are continuous and cyclic activities, as shown in the following diagram. Things to remember that, these above phases are NOT one-time activity. This phase takes the security evaluation results and suggests improvements on security implementation, and on security agreements as specified in, for example, SLAs and OLAs. It also checks the compliance of security implementation with IT security policy and security requirements defined in SLAs and OLAs. For doing this it carries out regular technical security audits of IT systems. This phase is responsible for measuring the success of the security implementation. It also ensures that the security measures are implemented according to the defined plan. This key element ensures that appropriate procedures, tools, and controls are in place to support the ITIL Information Security Management Policy. In this stage, information security management coordinates with service level management to understand the security requirements defined under SLA. The objective of this activity is to devise and recommend the appropriate security measures, based on an understanding of the organization’s requirement.
