ISO/IEC 27001 is an international standard that outlines a framework for managing sensitive information. In the context of software development, it is important to ensure that the software being developed is secure and that sensitive information is handled properly. To handle ISO 27001 in software development, you should:

Conduct a risk assessment

One of the first steps in handling ISO 27001 in software development is to conduct a risk assessment. This assessment should identify the potential threats and vulnerabilities that could affect the software development process and the information it handles. Once these risks have been identified, the organization should implement controls to mitigate or eliminate them. These controls can include technical measures, such as encryption and access controls, as well as organizational measures, such as employee training and incident response planning.

Establish a set of policies 

Another aspect of handling ISO 27001 in software development is to establish and maintain a set of policies and procedures. They should outline the organization’s approach to information security, including how it will identify, assess, and manage risks. They should also specify the roles and responsibilities of employees, contractors, and third-party vendors in relation to information security. Additionally, they should detail the procedures for incident management, including how to detect, respond, and recover from security breaches.

The software development process itself should also be designed to align with ISO 27001 requirements including

  • implementing secure coding practices ( input validation and error handling, to prevent common vulnerabilities. 

The development process should be designed to ensure that the software is tested and validated before it is released to production including

  • penetration testing and vulnerability scanning to identify and remediate any security issues.

ISO 27001 also requires organizations to implement a continual improvement process to ensure that their ISMS is kept up-to-date. This includes regular reviews of the ISMS, such as internal and external audits, to identify any areas for improvement. Additionally, organizations should be prepared to respond to changes in the threat landscape, such as new vulnerabilities or emerging threats, and update their ISMS accordingly.


Handling ISO 27001 in software development requires a comprehensive approach to information security. Organizations should conduct a risk assessment to identify potential threats and vulnerabilities, implement controls to mitigate or eliminate them, establish and maintain policies and procedures, and align the software development process with ISO 27001 requirements. They should also be prepared to review and update their ISMS regularly to ensure it remains up-to-date and effective in protecting sensitive information. With the right approach, organizations can ensure that their software development process is compliant with ISO 27001 and that their sensitive information is secure.
