Secure Software Development Framework Rules And Elements

What is SSDF (Secure Software Development Framework)?

For integrating security across the software development life cycle (SDLC), NIST’s Secure Software Development Framework (SSDF) offers best practices and principles in an organised manner.

Teams may detect and address vulnerabilities while safeguarding against possible attacks by using the SSDF’s practical recommendations for integrating security considerations into each step of development. The best practices for safe development, testing, and deployment established by the Software Development Framework improve software quality and foster user confidence.

Core principles of the Software Development Framework

Three guiding principles serve as the foundation for the Secure Software Development Framework, directing its efficacy and implementation:

Security by design

Rather than seeing security as a secondary concern, the Software Development Framework places a strong emphasis on incorporating security features and concerns into the architecture and design of software. This security by design methodology makes it simpler to identify any vulnerabilities early in the development cycle and to adopt mitigation measures.

Continuous improvement

Security is ongoing, according to the Secure Software Development Framework. Security protocols, methods, and policies must be updated and improved due to new threats and technology.

Organisations may maintain a competitive edge and guarantee that their software is resilient to new attacks by regularly evaluating and improving security measures.

Risk control

To manage and lower risks, effective risk management focusses on comprehending possible threats and vulnerabilities, assessing their impact, and putting in place the right controls. By managing risks, you can make sure that security initiatives complement your company’s business plans and risk appetite.

Major components of the SSDF

After reviewing the SSDF’s guiding principles, let’s focus to the six main parts of the framework that deal with system security and integrity:

Governance and policy

Any software system must have security controls and governance frameworks that address its creation, delivery, and use. The following are examples of governance and policy measures:

  • Defining jobs and duties
  • Specifying security objectives
  • following legal requirements

Secure design principles

Security should be included into software architecture and design, according to secure design principles. For software to achieve unmatched resilience, security must be included into architecture and design from the beginning.

Use safe software development techniques to meet secure design requirements, such as defense-in-depth tactics, minimising your attack surface by eliminating superfluous features, services, and code, lowering attacker entry points, and restricting access to vital resources.

Secure coding techniques

Writing code free of common security flaws and in accordance with code security best practices is a difficult task. Yet, methods like input validation, output encoding, and intelligent error handling aid in removing typical software flaws that adversaries may use against you.

Checking and confirming

Software is tested and certified for security and functionality. Code reviews, penetration testing, and static and dynamic analysis help find and repair software security problems before release.

Setting up and maintaining

This Software Development Framework component guarantees the maintenance of security protocols both during and after deployment. It comprises:

  • Software installation and deployment in regulated settings to avoid setup errors and illegal access
  • Making sure that software is robust against new threats by patching and upgrading it often to fix issues
  • Continuous monitoring should be prioritised in order to identify and address emerging security threats.
  • Ensuring software stays safe, compliant, and current as the threat landscape changes requires maintaining comprehensive documentation and change management procedures to monitor all upgrades and configurations.

Awareness and training in security

Training programs and security awareness raise awareness of emerging dangers and effective practices among stakeholders and development teams. To achieve these objectives, make sure that all individuals working on software development are aware of and abide by security procedures by providing frequent training and resources.

The software development lifecycle’s Software Development Framework

The ideas and elements of the Software Development Framework are relevant to every stage of the software development lifecycle, including crucial facets of software supply chain security. The SSDF may be included into each stage in the following ways:

Collection of requirements

Define and document both business-specific and general security needs throughout the requirements collecting stage. Next, include the criteria you have determined for software security into your project plan.

Creating

Incorporate security-related measures into the design phase. This procedure will serve as the foundation for your secure design. Threat modelling and risk assessments are used to identify potential security flaws. Keep in mind: It is best to detect and minimise hazards as early in the design phase as possible.

Advancement

Make sure developers adhere to safe coding procedures in this third stage. Use static code analysis and code reviews to confirm that the code is secure against vulnerabilities.

Testing

Prior to software release, do various security tests, such as dynamic analysis and penetration testing. By conducting thorough testing, you can identify your blind spots and address problems before to launch.

Deployment

Use all the fixes and updates that are available. Make sure new modifications don’t pose any security issues by using the right deployment methodologies and best practices, such as blue/green or red/black deployment.

Maintenance

Maintenance is a continuous procedure. Keep your systems under constant observation for changes and threats. Incorporate regular security audits into your maintenance procedures as well to guarantee ongoing protection and enforce security measures.

Technology and instruments that assist the Software Development Framework

Implementing the Software Development Framework is aided by a number of technologies and solutions that improve security procedures. Below are the top four:

ToolUse
Static analysis toolsThese tools examine source code without needing to execute it. Popular tools that look for weaknesses and problems in source code include SonarQube and Checkmarx.
Dynamic analysis toolsDynamic analysis tools analyze the software at runtime to identify security holes and vulnerabilities. ZAP and Burp Suite are two examples.
Configuration management toolsAs their name implies, these tools manage and protect software configurations and secure environments. Well-known configuration management solutions include Ansible and Chef.
Collaboration platformsPlatforms like Jira and GitHub facilitate communication and collaboration among development teams, enhancing the effectiveness of security practices.
