Digital threats are ever-evolving, a good practice is to start by followin a security framework. The International Organization for Standardization (ISO) sets the gold standard in this realm, with ISO 27001 playing a pivotal role in safeguarding information security.

Adhering to ISO 27001, particularly Annex A.12, is not just about meeting regulatory requirements; it’s about building a resilient, trustworthy business. In a world where data breaches and cyber-attacks are commonplace, implementing these standards without cutting corners will help you maintain your organization secure.

ISO 27001, Annex A.12, Operational Security

ISO 27001 encompasses 114 controls across 14 groups and 35 categories, it is a comprehensive framework but a complex one, it is designed to guide businesses on the cybersecurity journey. Annex A.12 focuses specifically on Operational Security, addressing critical elements such as operational procedures, malware protection, information backups, and more. Let’s delve into its main components:

1. Operational Procedures and Responsibilities (12.1): This control mandates the establishment of documented operating procedures to ensure that the organization’s operations are conducted correctly and securely. The focus is on establishing clear accountability across all levels of the organization. These documented procedures should provide guidance on various operational scenarios, such as: engagement with suppliers, employee onboarding and offboarding. The aim is to create a transparent and accountable environment where every stakeholder knows their responsibilities and the correct procedures to follow in various operational contexts.

2. Malware Protection (12.2): This control is about implementing appropriate measures to protect against malware/ransomware, you need it to protect your data, your IT systems and your employees. You should implement logical controls (sophisticated way to say technological solutions) such as EDR (Endpoint Detection and Response) email security solution, as well as user awareness training, to engage users and foster a cyber culture in your organization.

3. Backups (12.3): Backups should be your top priority when it comes to cyber resilience. They are essential for recovering from a cyber attack, ensuring that your data remains intact and accessible. A well-defined backup strategy is crucial, including regular testing of these backups to verify data integrity and availability.

By routinely checking your backup processes, you can confirm that your data can be restored quickly and accurately, minimizing downtime and reducing the impact of potential security breaches. Implementing a comprehensive backup plan not only safeguards your information but also fortifies your overall cyber defense strategy.

4. Logging and Monitoring (12.4): Essential for tracking activities and protecting information, encompassing event logging, operator logs, and synchronization. This includes controls for event logging, recording user activities, exceptions, and information security framework events, and the protection of log information. It’s recommended to have a SIEM SOC that collects, monitors and analyzes the thousands of logs generated daily from Active directory, firewalls, servers, IDS, Operating systems, and more.

5. Software Control (12.5): This control involves the management and validation of software on operational systems to prevent unauthorized software from being installed and potentially harming the system. Think of this as a digital gatekeeper that decides what software can go into your computers. It includes solutions such IAM (Identity and Access Management) et Secure Network Access.

6. Vulnerability Management (12.6): A proactive approach to identifying and mitigating technical weaknesses. It involves regularly scanning for technical vulnerabilities, assessing the risk they pose, and taking appropriate measures to address significant issues.

7. Information Systems Auditing (12.7): Implement a strategy for auditing your operational infrastructure and your cyber security posture.
