IT security in all phases of software development

Fixing a security problem in existing software after the development phase is many times more expensive than identifying and preventing it during the planning phase. In a Secure Software Development Lifecycle (Secure SDLC), information security is included right from the start and in all phases of development: in this way, agile development and IT security can be combined and costs and effort can be saved at the same time. In a Secure SDLC, DevSecOps processes and tools are used to automate security checks in order to keep the manual workload as low as possible.

One model for implementing a Secure SDLC is the Security Development Lifecycle (Microsoft SDL) developed by Microsoft, which divides the development cycle into the phases of training, requirements, design, implementation, verification, release and response, and provides processes and tools for each phase to ensure the information security of the product. The core idea of the Secure SDL is to focus as much on the security of an application as on its functionality – and to involve all stakeholders in order to guarantee the most holistic security possible.

Security Development Lifecycle

For this purpose, different methods are used in the various phases: for example, a threat analysis in the design phase, regular dynamic analyses, fuzzing or penetration tests in the verification phase, or static code analyses in the implementation phase. In order to implement a successful Secure SDLC, it is essential that all employees develop an awareness of IT security – therefore, for example, an IT security awareness workshop must be conducted in the training phase. Furthermore, ensuring information security is taken into account even after a product has been completed: In the release phase, a security review is conducted and an incident response plan is created. This provides instructions for minimizing damage and thwarting further attacks in the event of a security incident and ensures that you are well prepared for attacks.

Considering these multiple dimensions of IT security in all phases and areas can quickly become overwhelming: That’s why we are glad to support you in integrating information security into your SDLC and help you create the corresponding processes. This way, you can develop secure software faster and more reliably.
