Here is an overview of how security can be embedded into each phase of the SSDLC:
During the planning phase, it is important to identify the security requirements for the software and incorporate them into the project plan. This may include conducting a risk assessment to identify potential security threats and vulnerabilities and determining the appropriate controls to mitigate them.
Requirements and Analysis
In this phase, it is important to clearly define the security requirements for the software and ensure that they are understood and included in the software design. This may include developing a threat model to identify potential attacks and determining how the software will protect against them.
Design and Prototyping
During the design and prototyping phase, it is important to design the software with security in mind. This may include using secure design patterns, implementing appropriate controls, and conducting a security review of the design.
In the development phase, it is important to follow secure coding practices to ensure that the software is developed with security in mind. This may include using static analysis tools to identify potential vulnerabilities, following secure coding standards, and conducting regular code reviews.
During the deployment phase, it is important to follow secure deployment practices to ensure that the software is deployed securely. This may include conducting a security assessment of the deployment environment, implementing appropriate controls, and following best practices for securing the software in production.
In the maintenance phase, it is important to continue to prioritize security. This may include regularly patching the software to fix vulnerabilities, monitoring the software for security issues, and conducting regular security reviews to ensure that the software remains secure over time.
