ISO 27001 Remote Auditing: The Future Of Information Security Audits
Organisations have increasingly shifted to digital and remote work environments, requiring the traditional on-site audit process to evolve. No longer do companies want a suited-and-booted auditor arriving in their office with a checklist. Instead, ISO 27001 Remote Auditing is quickly becoming the standard for assessing an organisation's Information Security Management System (ISMS). At Tempo Audits, we’re at the forefront of this transition, offering comprehensive remote audit services that meet the rigorous demands of ISO 27001 and ISO 27006, which provide the guidelines for auditing companies against ISO 27001, while providing flexibility, efficiency, and cost savings to clients.
Let's explore how remote audits are conducted, the challenges and benefits of this emerging approach, and why adopting ISO 27001 remote auditing can be a game changer in achieving regulatory compliance and robust data risk management.
The Evolution of ISO 27001 Remote Auditing
Remote audits have evolved in response to the increased need for digital connectivity and more agile business operations. Where physical audits were previously the only route, with the onset of the pandemic in 2020, remote audits suddenly became a necessity overnight, with certification bodies and their regulating bodies, the accreditation bodies, swiftly developing processes to ensure that audits could continue to operate in a fully remote world. Whilst many companies have since returned to some form of physical working since the pandemic, the working structure of companies has changed indefinitely, with an increasing emphasis on hybrid and flexible working practices. With this in mind, the most recent updates to the auditing guidelines for ISO 27001, ISO/IEC 27006-1:2024, explicitly incorporated guidelines for remote audits. These changes address the growing trend of virtual operations and provide clear procedures for:
Deploying Remote Audits: New provisions detail how to plan, execute, and document remote audits using secure digital tools.
Risk Assessment: Certification bodies must assess whether a client is suitable for a remote audit, considering factors like the absence of critical on-site infrastructure and the presence of robust digital controls.
Audit Reporting: Audit reports must indicate the extent and effectiveness of remote auditing activities, ensuring transparency and confidence in the audit outcome.
This evolution supports ISO 27001 audits and aligns with broader trends in information security management.
How Is Auditing Done Remotely?
Conducting a remote audit involves leveraging technology to assess an organisation’s ISMS without the need for a physical visit. Here’s a step-by-step breakdown of the process:
Initial Risk Assessment
Before scheduling a remote audit, the certification body performs a risk assessment to determine that a remote audit can be used to deliver a fair and thorough audit. At Tempo Audits, this includes asking questions to verify:
Client Suitability: With questions, such as: Does the organisation have critical on-site infrastructure? Is the organisation’s work primarily administrative and desk-based? Is the team remote or hybrid?
IT Infrastructure: Are there secure and robust systems in place (e.g. encrypted video conferencing, secure document-sharing platforms) to facilitate the audit? Are the auditees confident using video tools?
Security Controls: Can digital evidence provide sufficient assurance that the information security controls are in place?
This initial risk assessment phase is crucial to ensure that remote auditing is viable for the client, thereby maintaining the integrity of the ISO 27001 certification process.
For a tech-focused certification body such as Tempo, the large majority of our clients are suitable for a remote audit given that: 1. they largely use cloud-based tools and therefore have no critical physical infrastructure, 2. their work is administrative and desk-based (rather than having any manufacturing or other physical operations), and 3. they are often remote or hybrid.
The Remote Audit Process
Once suitability is confirmed, the remote audit process follows a very similar process to a physical audit, with audit dates booked, and the auditor gathering evidence from the client over the course of these days. The primary difference is that, instead of the auditor being in a meeting room in your office asking for evidence in person, you’ll be on a video call and using screen-sharing to display evidence.
Key steps for the remote audit process include:
Preparation and Planning:
Scheduling: Aligning audit dates and times
Tool Setup: Ensuring that both the audit team and the client are equipped with secure communication tools such as Google Meets, Zoom, or Microsoft Teams
Execution:
Meetings: these are the bedrock of the audit. They’re the meetings that the auditor conducts with the organisation’s project lead throughout the audit to gather evidence.
For a fully synchronous audit, these meetings are the primary source of evidence for the auditor.
If the organisation wants a more “asynchronous” audit (harnessing “Agile Evidence Review” below) then the nature of these meetings will change, so that they take less time and become a place for the auditor to ask questions raised during Agile Evidence Review and gather further evidence.
Agile Evidence Review: Here, the auditor reviews digital records, policies and procedures and gathers evidence of conformity asynchronously (ie without the organisation’s representative there). This is only possible if the organisation has all their evidence accessible and wants to take this approach - and will typically be done in short blocks of time (e.g. 1 - 2 hour blocks) followed-up by a catchup “Meeting” between the Auditor and the Project Lead, where the Auditor can ask any questions that arose in the Evidence Review.
Virtual Interviews: Conducting interviews with key personnel through video conferencing. The auditor will agree with whom they will interview with the Project Lead.
Site Walkthroughs: Where necessary, clients may provide live video tours of physical facilities to verify physical security controls.
Reporting:
Audit Report: The report includes details on the remote methods used, the extent of evidence reviewed, and any recommendations or non-conformities identified.
Experienced auditors, such as an auditor from Tempo Audits, are adept at managing remote audits, ensuring that our remote audit services are as thorough and reliable as traditional on-site audits.
ISO 27001 Remote Auditing: Overcoming Hurdles & Embracing Opportunities
As with any evolving technology, an ISO 27001 remote auditing process presents challenges and opportunities. Understanding these aspects is critical to maximising the benefits of remote audits while mitigating potential drawbacks.
Challenges of Remote Auditing
Despite its many benefits, remote auditing comes with several hurdles:
1. Technical and Connectivity Issues
Internet Stability: Unreliable connectivity can disrupt video calls, delay document transfers, and impair real-time interactions.
Inadequate IT Infrastructure: Organisations may not always have the latest digital tools required for a seamless remote audit.
Security Risks: There is an inherent risk associated with transmitting sensitive audit data over the internet, making robust cybersecurity measures essential.
2. Verification of Physical Controls
Limited On-Site Observation: Without being physically present, auditors may face challenges verifying certain physical security measures.
Reliance on Digital Evidence: While photos and videos are helpful, they may not always capture the full context of a physical environment.
3. Evidence Collection and Authentication
Document Authenticity: Ensuring the genuineness of digital documents can be difficult without the context provided by an on-site audit.
Potential for Misrepresentation: There is a risk that digital evidence might be manipulated, which requires auditors to employ stringent verification techniques.
4. Communication Barriers
Reduced Informal Interaction: On-site audits often allow for spontaneous conversations that can reveal underlying issues. Remote audits may limit these opportunities.
Scheduling Challenges: Coordinating meetings across different time zones can be challenging, particularly for global organisations.
Benefits of Remote Auditing
On the other side, remote auditing brings several compelling advantages:
1. Flexibility for Clients
Convenience: Remote audits can be scheduled with minimal disruption to the daily operations of an organisation.
Accessibility: Clients can engage in the audit process from any location, facilitating faster and more efficient assessments.
2. Cost Savings
Reduced Travel Expenses: Since auditors do not need to travel, clients save on travel and accommodation costs, which would normally be passed on.
Lower Operational Costs: The streamlined process will lead to lower costs, making ISO 27001 certification more accessible for many organisations.
Environmental Benefits: With fewer auditors travelling, there is a reduction in carbon emissions, contributing to environmental sustainability.
3. Enhanced Audit Efficiency
Faster Turnaround: Remote audits can often be completed more quickly than on-site audits, reducing the time to certification.
Improved Scheduling: The ability to conduct audits virtually allows for more flexible scheduling, accommodating clients’ busy calendars.
4. Maintaining Rigour in Audit Procedures
Effective Evidence Collection: Despite being remote, auditors can still collect comprehensive digital evidence using secure, encrypted platforms.
Clear Communication: Structured virtual meetings and well-planned audit sessions ensure that all key information is thoroughly reviewed.
Risk Assessment Integration: Conducting a preliminary risk assessment ensures that only organisations with robust digital infrastructures undergo remote audits, maintaining the overall quality and reliability of the audit process.
