Why does ThreatLocker recommend adding Ringfencing restrictions to elevated applications?

Adding Ringfencing restrictions to elevated applications is advisable because it effectively prevents application hopping. This refers to the scenario where a malicious actor leverages one application to access or control another within the same elevated environment. Elevated applications often possess higher permissions, which makes them prime targets for exploitation. By implementing Ringfencing, organizations can enforce strict boundaries around what an elevated application is allowed to do, significantly reducing the risk of unauthorized access to other applications and sensitive data.

This approach not only protects the integrity of the elevated application but also mitigates the threat posed by potential vulnerabilities in that application being exploited to compromise other applications. Therefore, Ringfencing serves as a critical defense mechanism in a layered security strategy, ensuring that even if one application is compromised, the attack cannot propagate easily to other components in the system.
