Based on the given certificate properties:
* SuperTrust RSA 2018 is an intermediate certificate authority (CA) because it is issued by BudgetCert Global Root CA, which is the top-level certificate authority.
* BudgetCert is the top-level CA (root CA) in this public key infrastructure (PKI) hierarchy, as it issues certificates to SuperTrust RSA 2018 and has no issuer of its own.
Therefore, SuperTrust RSA 2018 is the intermediate CA, and BudgetCert is the top-level (root) CA in this PKI chain of trust. The www.budgetcert.com certificate is the leaf or end-entity certificate, which is used for the website itself.

Implementing MFA can add an extra layer of security to protect against unauthorized access if the vulnerability is exploited. Reviewing the application logs can help identify if any attempts have been made to exploit the vulnerability, and deploying a WAF can help block any attempts to exploit the vulnerability. While the other options may provide some level of security, they may not directly address the vulnerability and may not reduce the risk to an acceptable level.

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analyze the open-source and third-party components used in software development to identify known vulnerabilities, outdated dependencies, or licensing issues.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 ARO (annualized rate of occurrence) for successful breaches is the number of times an event is expected to occur in a year. To calculate the ARO for successful breaches, the engineer can divide the number of breaches by the number of years. In this case, the company's data has been breached two times in four years, so the ARO is 2 / 4 = 0.5. The other options are incorrect calculations.
