    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.
