Study Notes

System Development Life Cycle (SDLC)

  • Planning phase includes reviewing project requests, prioritizing them, allocating resources, and forming a project development team.
  • Analysis phase involves detailed activities such as studying the current system, determining user requirements, and recommending solutions.
  • Design phase focuses on acquiring necessary hardware and software, and developing system specifications in detail.
  • Implementation phase includes developing the program, testing the new system, and training users on its operation.
  • Support phase revolves around identifying errors and enhancements, monitoring system performance, and making updates as required.

Security System Development Life Cycle (SecSDLC)

  • SecSDLC mirrors the phases of traditional SDLC but emphasizes security throughout each step of the system development process.
  • Includes managing cybersecurity risks to protect the Confidentiality, Integrity, and Availability (C.I.A) of organizational information assets.

Planning and Analysis in SecSDLC

  • Define potential impacts on the organization or individuals due to security breaches.
  • Conduct preliminary risk assessments to describe initial security requirements.

Design in SecSDLC

  • Perform comprehensive risk assessments and analyze security functional and assurance requirements.
  • Develop a complete security plan that details the information system (IS) characteristics and its security needs.

Implementation in SecSDLC

  • Involves inspection of the system, acceptance testing, and systematic integration of security controls.

Support in SecSDLC

  • Monitors ongoing security levels, making updates as changes occur in the environment to maintain system integrity.
  • Emphasizes continuous monitoring to adapt to new security challenges.

Comparison of SDLC and SecSDLC

  • SecSDLC adheres to the same phases as standard SDLC but specifically identifies and addresses potential security threats.
  • Effective planning within SecSDLC requires addressing all conceivable threats to ensure a robust information system.
