ISO 27001:2022 Annex A 8.7 Checklist Guide

ISO 27001 A.8.7 Protection Against Malware Checklist

A.8.7 Protection Against Malware in the ISO/IEC 27001:2022 standard is a critical control requiring comprehensive measures to prevent, detect, and respond to malware threats. Malware, including viruses, ransomware, spyware, and other malicious software, poses significant risks to information security, potentially disrupting business operations, compromising sensitive data, and causing financial losses.

Implementing robust anti-malware strategies involves several key components and addressing specific challenges that a Chief Information Security Officer (CISO) might encounter.

This detailed guide outlines the implementation of A.8.7, identifies common challenges, provides solutions, and describes how ISMS.online can support these efforts. Additionally, a comprehensive compliance checklist is provided to help organisations demonstrate adherence to this control.
