Management Agreement Obtain agreement from appropriate management for any audit access to systems and data. 2. Scope Control Clearly define and agree on the scope of the technical audit tests with relevant management. 3. Read-Only Access Limit audit tests to read-only access to software and data. If read-only access isn’t sufficient, have a qualified administrator with the necessary access rights perform the test on behalf of the auditor. 4. Security Verification If access is granted, ensure that the devices used for accessing the systems (e.g., laptops or tablets) meet security requirements, such as having up-to-date antivirus software and patches. 5. Isolated Access If more than read-only access is required, work with isolated copies of system files. Delete these copies after the audit is complete, or secure them if they must be retained for audit documentation purposes. 6. Special Requests Identify and agree on any special or additional processing needs, such as running specific audit tools. 7. Timing of Tests Schedule audit tests that could impact system availability to occur outside of business hours. 8. Monitoring and Logging Ensure all access during audit and test activities is monitored and logged for security and compliance purposes. ### Additional Information Audit tests and other assurance activities may also take place on development and test systems. These activities can affect the integrity of code or expose sensitive information, so the same care and guidelines should be applied in these environments as well. - [Getting Started](https://knowledge.adoptech.co.uk/getting-started?hsLang=en#main-content) - [Getting Started](https://knowledge.adoptech.co.uk/getting-started?hsLang=en#getting-started) - [Accounts & Billing](https://knowledge.adoptech.co.uk/getting-started?hsLang=en#accounts-billing) - [FAQ's on Adoptech](https://knowledge.adoptech.co.uk/faqs-on-adoptech?hsLang=en#main-content) - [Frameworks](https://knowledge.adoptech.co.uk/faqs-on-adoptech?hsLang=en#frameworks) - [Policies & Documents](https://knowledge.adoptech.co.uk/faqs-on-adoptech?hsLang=en#policies-documents) - [Risk Management](https://knowledge.adoptech.co.uk/faqs-on-adoptech?hsLang=en#risk-management) - [Supplier Management](https://knowledge.adoptech.co.uk/faqs-on-adoptech?hsLang=en#supplier-management) - [Audit Preparation](https://knowledge.adoptech.co.uk/faqs-on-adoptech?hsLang=en#audit-preparation) - [Trust Centre](https://knowledge.adoptech.co.uk/faqs-on-adoptech?hsLang=en#trust-centre) - [User Management](https://knowledge.adoptech.co.uk/faqs-on-adoptech?hsLang=en#user-management) - [Frameworks & Certifications](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#main-content) - [ISO 27001](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#iso-27001) - [ISO 42001](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#iso-42001) - [Cyber Essentials](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#cyber-essentials) - [CAF](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#caf) - [PCI-DSS](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#pci-dss) - [SOC2](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#soc2) - [Data Privacy (GDPR)](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#data-privacy-gdpr) - [DORA](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#dora) - [ISO 9001](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#iso-9001) - [ISO 22301](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#iso-22301) - [ISO 14001](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#iso-14001) - [NIST 800-53](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#nist-800-53) - [NIST-CSF](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#nist-csf) - [NIS2](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#nis2) - [ISO 20000-1](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#iso-20000-1) - [HIPAA](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#hipaa) - [Integrations](https://knowledge.adoptech.co.uk/integrations?hsLang=en#main-content) - [Cloud Infrastructure](https://knowledge.adoptech.co.uk/integrations?hsLang=en#cloud-infrastructure) - [Identity & Access](https://knowledge.adoptech.co.uk/integrations?hsLang=en#identity-access) - [DevOps & Code](https://knowledge.adoptech.co.uk/integrations?hsLang=en#devops-code) - [Project Management](https://knowledge.adoptech.co.uk/integrations?hsLang=en#project-management) - [HR & People Systems](https://knowledge.adoptech.co.uk/integrations?hsLang=en#hr-people-systems) - [Security & Devices](https://knowledge.adoptech.co.uk/integrations?hsLang=en#security-devices) - [Communication & Collaboration](https://knowledge.adoptech.co.uk/integrations?hsLang=en#communication-collaboration) - [Legal & Regulations](https://knowledge.adoptech.co.uk/legal-regulations?hsLang=en) - [Security Guidance](https://knowledge.adoptech.co.uk/security-guidance?hsLang=en) - [Troubleshooting](https://knowledge.adoptech.co.uk/troubleshooting?hsLang=en) [![Chill listening crop-3](https://knowledge.adoptech.co.uk/hs-fs/hubfs/adoptech-logo-1.png?width=209&height=54&name=adoptech-logo-1.png "Chill listening crop-3")](https://adoptech.co.uk/) Copyright © 2026, Adoptech Ltd.
