FlexxGuard protects Windows-based Internet and intranet clients against suspicious applets by regulating Java applet access to Windows system resources. Rather than quarantining all applets from client resources, FlexxGuard defends against malicious attacks by alerting Java clients to the presence of suspicious applets. With FlexxGuard, security policies for downloaded applets are configured on the client. When an applet is downloaded, FlexxGuard compares the applet's list of required system resources, the creator's identity (also called a "stamp"), its download type (e.g. financial report), and its origins (e.g. IBM) with the user- and administrator-defined security policies. Conflicts are presented to the user for resolution through a graphical user interface. FlexxGuard's dynamic security enforcer uses the resulting "capability list" to determine whether to grant access to a particular system resource. System administrators can set general network-wide policies. FlexxGuard also offers encryption and decryption of Java downloads for further protection. |
