What application interaction does ThreatLocker recommend preventing with Ringfencing?

ThreatLocker recommends preventing specific application interactions using Ringfencing to enhance security, particularly concerning PowerShell. PowerShell is a powerful scripting language and shell used for task automation and configuration management in Windows environments. Its capabilities allow users to execute scripts and commands that can interact with various system components and applications.

Because of PowerShell's extensive permissions and potential for abuse, limiting its interaction with other applications helps mitigate risks associated with malicious scripts or unauthorized activities. By implementing Ringfencing, organizations can enforce strict controls over what PowerShell can access and which applications it can interact with, thereby reducing vulnerabilities and the surface area for potential attacks.

In contrast, while SQL databases, file storage applications, and web browsers are also integral components of many IT environments, they do not present the same level of risk due to their normal operational usage as PowerShell does. Therefore, the emphasis on restricting PowerShell interactions through Ringfencing is particularly relevant for maintaining a secure environment.
