An Information Security Management System (ISMS) is a set of actions that an organization needs to perform in order to: Identify partners and their expectations from the organization in the matters of information security. Identify which dangers exist for the information security. Define controls (shields) and other relief strategies to handle dangers. Set clear goals on what should be accomplished with information security. Implement all the controls and other hazard mitigation strategies. Continuously monitor if the realized system is in tandem with the set standards. Make constant improvements to make the entire ISMS work better. ISO 27001 Certification helps in retaining the required strategies for your own ISMS.
