App Integrity Protection

Security for Microsoft .NET Mobile Applications

.Net Software Security

Microsoft .NET offers an efficient framework for developing and deploying Windows applications, including Web 2.0 server and client-side applications. However, it also uses Microsoft intermediate language (MSIL) or Common Intermediate language (CIL), which contains highly detailed metadata that makes compiled applications easy to reverse engineer, tamper and pirate. Once Microsoft .NET applications are deployed, hackers and competitors have easy access to the source code and the embedded IP within the applications themselves.

GuardIT for .NET protects managed code in mixed-mode and pure managed-code assemblies. It can be used for protecting Microsoft .NET managed code in pure managed-code or with GuardIT for Windows in mixed mode assemblies. GuardIT for .NET provides various Guards for obfuscating and encrypting character strings in managed code. The obfuscation Guards in GuardIT for .NET transform program instructions into code that is difficult to understand, for instance by inserting garbage code. These transformations do not affect the functionality of the protected application. The checksum guard in GuardIT for Microsoft .NET Framework provides strong anti-tamper capability by detecting whether a program has been modified by computing a checksum within a specified range.
