According to the guidelines, who is responsible for establishing mitigations and waivers?

The correct answer highlights that the CA SAPCO, which stands for the Central Access Security and Policy Compliance Office, holds the responsibility for establishing mitigations and waivers. This role includes assessing risks associated with the handling of sensitive information and ensuring that appropriate security measures are in place to safeguard data integrity and confidentiality. The CA SAPCO is typically tasked with providing oversight and establishing policies that govern security practices, thereby evincing their authority in decision-making processes related to mitigations and waivers.

The other options reflect roles that may be involved in security practices but do not carry the same level of authority or responsibility for establishing policy-based mitigations and waivers. Project managers, for example, may implement security measures within a project but typically do not establish overarching policy or guidelines. The facility manager may ensure that physical security is maintained in the facility, yet their role is distinct from the strategic security framework managed by CA SAPCO. Similarly, while the Department of Justice may influence legal aspects of security compliance, they do not have direct responsibility for establishing security mitigations and waivers within this specific context.
