Study Notes
CISSP Domain 8: Software Development Security
Overview
- Focuses on integrating security into the software development lifecycle (SDLC).
- Ensures that applications are secure and protected against vulnerabilities throughout their development and operational phases.
Key Concepts
-
Secure Software Development Life Cycle (SDLC)
- Phases: Planning, Requirements, Design, Development, Testing, Deployment, Maintenance.
- Security should be incorporated at each phase.
-
Security Controls in Software Development
- Preventive Controls: Techniques to prevent security incidents (e.g., code reviews, secure coding standards).
- Detective Controls: Mechanisms to identify security flaws (e.g., static/dynamic code analysis).
- Corrective Controls: Responses to incidents, such as patching vulnerabilities.
-
Common Software Vulnerabilities
- Injection flaws (e.g., SQL Injection)
- Buffer overflows
- Cross-site scripting (XSS)
- Insecure deserialization
-
Security in Software Architecture
- Design for security: threat modeling, data flow diagrams.
- Use of secure frameworks and libraries.
- Implementing security design principles (e.g., least privilege, defense in depth).
-
Secure Coding Practices
- Input validation and output encoding.
- Error handling and logging.
- Authentication and session management.
-
Testing for Security
- Security testing types: static analysis, dynamic analysis, penetration testing.
- Ensuring software is free from known vulnerabilities before deployment.
-
Deployment and Maintenance
- Secure configuration management.
- Regular updates and patch management.
- Vulnerability management processes.
-
Software Development Models
- Agile and DevOps: Incorporating security practices in iterative development.
- Waterfall: Traditional model with defined phases, emphasizing initial security requirements.
-
Third-Party Software Risks
- Evaluating the security of third-party components and libraries.
- Implementing controls for supply chain risk management.
-
Regulatory and Compliance Considerations
- Awareness of legal and industry standards (e.g., OWASP, ISO 27001).
- Compliance implications related to data protection and privacy.
Best Practices
- Educate developers on secure coding techniques.
- Incorporate security training and awareness programs.
- Regularly review and update security policies and procedures.
- Foster a security-first culture within the development team.
Overview of CISSP Domain 8
- Emphasizes integrating security into the Software Development Lifecycle (SDLC).
- Aims to keep applications secure against vulnerabilities across all phases.
Secure Software Development Life Cycle (SDLC)
- Key phases include Planning, Requirements, Design, Development, Testing, Deployment, and Maintenance.
- Security measures should be embedded in each of these phases.
Security Controls in Software Development
- Preventive Controls: Utilize techniques like code reviews and establish secure coding standards to avert security incidents.
- Detective Controls: Employ tools for static and dynamic code analysis to uncover security flaws.
- Corrective Controls: Activate responses to incidents, including patch management for identified vulnerabilities.
Common Software Vulnerabilities
- Injection flaws such as SQL Injection.
- Buffer overflow exploits.
- Cross-site scripting (XSS) vulnerabilities.
- Risks from insecure deserialization processes.
Security in Software Architecture
- Design must incorporate security via threat modeling and data flow diagrams.
- Use secure frameworks and libraries to bolster overall security.
- Adhere to security design principles like least privilege and defense in depth.
Secure Coding Practices
- Focus on input validation and output encoding to safeguard data.
- Implement robust error handling and logging mechanisms.
- Ensure effective authentication and session management techniques.
Testing for Security
- Perform various types of security testing, including static analysis and penetration testing.
- Validate that software is free from known vulnerabilities prior to deployment.
Deployment and Maintenance
- Employ secure configuration management strategies.
- Maintain a routine for updates and patch management.
- Develop processes for vulnerability management to ensure ongoing security.
Software Development Models
- Agile and DevOps methodologies prioritize the incorporation of security in iterative workflows.
- The Waterfall model emphasizes securing initial requirements with a linear approach.
Third-Party Software Risks
- Conduct evaluations of third-party components and libraries for security integrity.
- Establish controls aimed at managing supply chain risks associated with third-party software.
Regulatory and Compliance Considerations
- Maintain awareness of legal standards and industry best practices such as OWASP and ISO 27001.
- Understand the compliance implications surrounding data protection and privacy laws.
Best Practices
- Provide developers with training on secure coding methodologies.
- Establish security training and awareness initiatives for the entire team.
- Regularly review and update security policies and procedures to adapt to emerging threats.
- Cultivate a security-first culture throughout the development organization.
