What belongs in the information security policy for software development?
An information security policy for software development is the document in which you set out how your organization handles the security of information, systems and code. For a software company, this covers two things at once: the security of what you build, and the security of the environment in which you build it. Both belong in the same document, even though they are substantively different subjects.
In practice, this means the policy usually addresses the scope (which systems and which development projects fall under it), responsibilities (who decides, who manages, who monitors), the way access to source code and development environments is regulated, how vulnerabilities in your own code are identified and resolved, how test environments are treated differently from production environments, how incidents are recorded and how the policy itself is maintained and reviewed. A questionnaire from a customer often asks for precisely this type of document as evidence, not for a technical description of your source code.
Two layers: the product and the development environment
The first layer concerns the product: the software you deliver to customers. This includes a description of how you handle vulnerabilities discovered after delivery, how updates and patches reach customers, and who within the organization is responsible for following up on reports of security issues in the product.
The second layer concerns the development environment: the environment in which your team works. This includes the version control environment, the build and test pipeline, and the separation between test and production environments. Here it is about questions such as who may access the source code, how changes are checked before they go live, and how access is revoked when someone leaves the team. Both layers can appear in the same document, but are often described separately because the risks and their owners differ.
Why a customer asks for this
Organizations that themselves fall under the duty of care are obliged to assess the risks posed by their suppliers. A software company that develops for such an organization thus receives questions that do not stem from their own obligation, but from the supply chain. An information security policy is then often the first piece requested, because it shows in a single document how security has been addressed systematically. If it is missing, you must explain each point separately in a questionnaire, which takes more time and is less convincing than an existing document.
Whether your organization itself falls under the duty of care, is affected through the supply chain, or neither, is not immediately apparent. in a few questions, see where your organization stands provides a first indication of this, with an explanation of why.
How this policy relates to individual measures
An information security policy does not stand alone. It describes in broad terms how you approach security, while the individual measures — access control, backups, incident recording, supplier assessment — are the concrete implementation of it. If you write the policy without having the underlying measures in place, you have a document that does not match practice. Conversely, it is also difficult: individual measures without an overarching policy look fragmented to those asking for it. the overview of all topics by situation shows how these components relate to each other.
What is often missing in practice
In many first versions of such a policy, a clear owner for each component is missing: who is responsible for keeping the access policy up to date, who for the patch policy. A fixed evaluation date is also often lacking, which means a policy from two years ago is still presented as current while the development pipeline has changed in the meantime. And a third point that is often missing: an explicit link between the policy and the evidence that demonstrates it is actually being implemented, such as access rights logs or a list of applied patches.
Assess your own situation
Which components are exactly expected depends on the role of your organization in the supply chain and on what a specific customer asks for. This article describes the common structure, not a mandatory template, and the statutory text itself does not prescribe a fixed layout. For an assessment of your specific situation, a lawyer or the competent authority is the appropriate party. frequently asked questions about these types of documents provides an additional overview of what is often asked.
Would you like to see how such a policy, together with the underlying measures and evidence, is maintained in an ongoing dossier instead of as a standalone document? how secria.eu builds and maintains the information shows that.
