Defenses against BGP hijacks include IP prefix filtering, meaning IP address announcements are sent and accepted only from a small set of well-defined autonomous systems, and monitoring Internet traffic to identify signs of abnormal traffic flows.

Software composition analysis (SCA) is the most effective method to mitigate third-party risks in a software supply chain. SCA tools analyze the open-source and third-party components used in software development to identify known vulnerabilities, outdated dependencies, or licensing issues. By integrating SCA into the development environment, the company can proactively address risks related to external libraries or codebases that may introduce vulnerabilities into the software supply chain. CASP+ emphasizes the importance of securing the supply chain, particularly by identifying and addressing risks introduced by third-party software components.

The organization is implementing homomorphic encryption. Homomorphic encryption is a type of encryption that allows computations to be performed on encrypted data without decrypting it first. This means that the organization can analyze the customers' data and deliver analysis results without being able to see the raw data, preserving the privacy and confidentiality of the customers. Homomorphic encryption can enable various applications, such as cloud computing, machine learning, and data analytics, that require processing sensitive data without compromising security.
