Which security method should be included in a defense-in-depth, when examined from the perspective of a content security policy?

The inclusion of technological controls in a defense-in-depth strategy is essential when examining a content security policy. This approach emphasizes the use of various technical measures to protect data and systems from threats. Technological controls can include mechanisms such as firewalls, intrusion detection systems, encryption, and secure coding practices, which are crucial for implementing and enforcing security policies effectively.

In the context of a content security policy, technological controls specifically enable organizations to define and enforce how content is handled by web applications, protect against cross-site scripting (XSS), and mitigate other vulnerabilities that could be exploited by attackers. By deploying these controls, an organization adds multiple layers of protection that work together to defend against the potential threats to its content and data, thus enhancing the overall security posture.

While other methods such as contractual enforcement of policies, training programs, and strong access controls are also valuable components of comprehensive security management, they typically serve to complement technological measures rather than fulfill the core technical requirements of a defense-in-depth strategy focused on a content security policy.
