Secure Bill of Materials (SBoM) as adeterrance for supply chain attacks

The recent SolarWinds assault, in which hackers entered the software supply chain of a prominent cybersecurity company, demonstrates the importance of a Secure Bill of Materials (SBoM) in DevSecOps. A Bill of Materials is a list of all the components, libraries, and dependencies used to construct a software application. It is a vital component of DevSecOps since it enables developers to identify and trace the origin and versions of all application components.

By introducing malicious code into a software update, hackers were able to acquire access to the software supply chain during the SolarWinds attack. By utilizing a secure BoM, developers can verify that they only use validated, trustworthy components and can swiftly discover and eliminate any malicious code.

DevSecOps implementation of a secure BoM begins with the usage of a software composition analysis (SCA) tool. These tools analyze the codebase and identify all of the application's components, libraries, and dependencies. The developers are then able to discover and eliminate any potential hazards by comparing this list to a known list of vulnerabilities and security issues.

In addition to using a SCA tool, it is essential to have a mechanism in place for frequently updating the Bill of Materials (BoM). This should contain a method for checking the authenticity of new components and a method for deleting components that are no longer in use or have been identified as a security risk.

Utilizing a centralized management system for tracking and storing the Bill of Materials is another crucial feature of a secure Bill of Materials. This enables developers to immediately access and see the Bill of Materials and to discover and remove any harmful code that may have been added to the software supply chain.

It is also essential that all stakeholders, including the development, security, and operations teams, have access to and are taught on how to use the Bill of Materials. This ensures that everyone is on the same page regarding the identification and mitigation of security issues.

Using a secure Bill of Materials in DevSecOps is a vital step in preventing supply chain attacks such as the SolarWinds incident, as a conclusion. By utilizing a software composition analysis tool, adopting a method for periodically updating the Bill of Materials, and implementing a centralized management system, application developers can verify that they only use trustworthy components.
