What is DISA?

DISA stands for Defense Information Systems Agency, an agency of the United States Department of Defense (DoD). DISA’s mission is to plan, develop, deploy, and operate secure and reliable IT and communication systems and services to enable the military to accomplish its missions.

What are DISA STIGS?

DISA maintains Security Technical Implementation Guides (STIGs) to ensure compliance with DoD security policies. The guides provide configuration instructions for specific products and versions of various software, operating systems, and network devices. STIGs serve as standardized instructions for those within or serving the DoD, and as general best practices for other organizations outside of the DoD.

DISA regularly updates and creates new STIGS based on evolving threats, new technology and revised DOD security policy. Each STIG has an overview section that with its creation date, version, findings severity summary, and a short description. This is further broken down into findings. Each STIG focuses on the configuration of a single piece of software or hardware, and each finding focuses on securing a particular vulnerability.

Each finding is given a unique identifier and a severity category I-III corresponding to High, Medium, and Low. They also provide a detailed rationale for the finding with background information and other relevant documentation. The body of the finding is reproduction and mitigation instructions so that the person working to comply with the STIG can determine their vulnerability and follow the steps to prevent it from being exploited. The findings should be addressed in order of severity and generally more severe findings are more difficult to implement.

Who uses DISA STIGs?

Compliance with STIGs is typically mandatory for all DoD information systems, both within the DoD and for contractors and vendors. Non-DoD organizations often look to STIGs as a benchmark for cybersecurity best practices due to their completeness in identifying and addressing security concerns. However, they may need to adapt STIGs to fit specific security requirements.

What are DISA STIG checklists?

STIG documentation is commonly known as STIG Checklists. These outline the hardening criteria for hardware, software, or network systems, detailing the steps necessary to secure each component effectively. They will likely vary in accordance with the security standards of an organization and the technologies integrated into their development procedures.

What is a DISA STIG framework?

The DISA STIG framework, or Defense Information Systems Agency Security Technical Implementation Guide framework, is a set of cybersecurity guidelines and standards developed by the DISA. It consists of a structured collection of documents that provide detailed instructions and recommendations for securing various information systems and software used within the DoD.

What is the Application Security and Development (AppSecDev) STIG?

The Application Security and Development STIG provides security requirements for DOD applications from development to deployment. It is comprised of nearly 300 findings, 32 of which are category I. They describe secure coding practices, necessary features, and configuration and operational requirements intended to reduce risk and the applications cybersecurity footprint.

Where does the AppSecDev STIG fit within the DISA STIG framework?

The Application Development STIG complements other STIGs within the DISA framework, such as those for operating systems, databases, and web servers. By following the recommendations outlined in the Application Development STIG, developers and system administrators can help ensure that DoD applications are developed and deployed in a secure manner, thereby reducing the risk of security breaches and data compromises.

What are the key components of the AppSecDev STIG?

Key components covered in the Application Development STIG include:

Secure coding practices: Guidelines for writing secure code to prevent common vulnerabilities such as injection attacks (e.g., SQL injection, cross-site scripting), buffer overflows, and improper input validation.

Application security testing: Requirements for conducting thorough security testing throughout the software development lifecycle (SDLC), including static code analysis, dynamic application security testing (DAST), and penetration testing.

Secure configuration management: Recommendations for securely configuring application servers, databases, web servers, and other components to minimize attack surfaces and vulnerabilities.

Authentication and authorization: Requirements for implementing strong authentication mechanisms, access controls, and authorization policies to protect sensitive data and resources.

Secure communication: Guidelines for securely transmitting data between application components and external systems using encryption, secure protocols (e.g., HTTPS), and secure network configurations.

Secure deployment practices: Recommendations for securely deploying and configuring applications in production environments, including secure update and patch management and retirement processes.

Compliance and documentation: Requirements for documenting security controls, configurations, and test results to demonstrate compliance with applicable security standards and regulations.

What might be included in a STIG Checklist for the AppSecDev STIG?

The specific items included in an Application Development STIG checklist will be designed to cover the different components outlined in the STIG. Generally, these checklists are meant to note the compliance of a certain product, process, or service in reference to the guides set by the DISA. They will therefore vary depending on an organization’s security requirements and the technologies used in their development process.

How can LDRA support the AppSecDev DISA STIGs?

LDRA provides a suite of tools aimed at ensuring the safety, security, and reliability of software development. The LDRA tool suite and LDRA point products can be used to support compliance with the Application Development STIG by using automation to help developers adhere to secure coding practices. It enables the developer to conduct thorough code analysis and reviews, security testing, and document compliance with security requirements. Here’s how LDRA tools can be utilized to support various aspects of the Application Development STIG:

Static code analysis: The TBvision component of the LDRA tool suite and the LDRArules point product can each perform static code analysis to identify security vulnerabilities and coding errors early in the development process, allowing the fixes to “shift left” and reducing the time required to fix the errors. This includes detecting potential issues such as memory leaks, buffer overflows, injection vulnerabilities, and improper input validation. By analysing the source code statically, security weaknesses can be addressed when they are written, long before they manifest as vulnerabilities in the final product.

Dynamic analysis: The dynamic analysis capabilities of LDRA tools enable developers to assess their applications during runtime. This involves testing the application’s behaviour under various conditions to identify security vulnerabilities such as runtime errors, dead or infeasible code, and authentication weaknesses. Dynamic analysis helps ensure that applications are resilient to attack vectors and perform as expected in real-world scenarios.

Structural coverage analysis: (also known as code coverage analysis) is used to measure the effectiveness of test cases and in exercising different parts of the codebase. By assessing coverage, developers can identify areas of the application that require additional testing to comply with structural coverage requirements. This ensures that security-critical components of the application are thoroughly tested to uncover potential vulnerabilities.

The TBvision and TBrun components of the LDRA tool suite provide system and unit test capabilities respectively. The LDRAcover and LDRAunit point products fulfil similar roles on a “stand alone” basis.

Compliance documentation: The LDRA tool suite generates comprehensive reports that demonstrate compliance with security standards. Developers can use these reports to track security testing activities, document security control requirements implemented in the codebase, and provide evidence of compliance with the Application Development STIG requirements.

Integration with development workflows: LDRA tools integrate into existing software development workflows, enabling seamless incorporation of security testing and regression activities into the development process. Integration with IDEs and version control systems allows developers to conduct security testing iteratively throughout the software development lifecycle.

These tools facilitate secure coding practices, thorough testing, and documentation of security controls, ultimately reducing the complexity of achieving DoD security standard compliance and enhance the security posture of their applications. By utilizing LDRA for static and dynamic analysis, code coverage, and the artifacts generated in the processes, developers can effectively meet the requirements outlined in the Application Security and Development STIG.
