ISO 27001 is the international standard for an information security management system (ISMS). It sets requirements and control objectives organisations use to manage information risk and protect assets.
Operationally it requires asset inventories, risk assessments, documented controls and regular review. It affects technical controls such as access management, logging, encryption and backups and can increase operational overhead for engineering and ops teams.
Defines access restrictions, privileged account controls, authentication and authorisation to support ISO 27001 compliance.
Gather and retain logs, reports and records that demonstrate controls and support ISO 27001 audit evidence.
Requirements and controls for protecting, classifying, transferring, retaining and otherwise controlling data in line with ISO 27001.
Specifies accountability, required policies and controls, and the evidence needed to demonstrate ISO 27001 compliance.
ISO 27001 touches systems across the IT estate. It links to identity, endpoint, network, storage and observability tools and relies on those systems for control enforcement and evidence.
Consider it when selecting products, defining access and retention policies, and managing suppliers. Teams should be clear who owns controls, how they are evidenced, and how controls operate across cloud and on-prem systems.
