Study Notes
Secure Software Development Lifecycle
- Secure software development is a process, not a product.
- The key is to have proper documentation.
- There are five phases in the secure software development lifecycle:
- Requirements Phase: This phase is about defining the security requirements for the software.
- Design Phase: This phase translates the security requirements into a secure design.
- Implementation Phase: This phase is where the actual software is built.
- Testing Phase: This phase involves testing the software to ensure that it meets the security requirements.
- Maintenance Phase: This phase involves ensuring that the software remains secure over time, including responding to newly discovered vulnerabilities.
- Secure software development is challenging because of software complexity. Larger software with many components can make it hard to find and fix security bugs.
- Extensibility is another challenge. It can be hard to evaluate code which has not arrived yet.
- Miscommunication within large development teams is another challenge.
- More than 81% of software projects do not coordinate security practices across development phases.
- Network Attacks: The rise of network access to applications has made it easier to launch attacks on applications from remote locations.
- Vulnerability Database reveals that many serious application security problems are due to programming errors.
The Implementation Phase
- Security designs and coding standards are used to write secure code.
- Programmers must be aware of known vulnerabilities in coding.
- Security vulnerabilities pose a great risk to organizations.
The Testing Phase
- The primary objective is to ensure the final product meets both functional and non-functional requirements.
- The software needs to meet all security requirements and function as intended.
