A system and method is provided for managing security on a server that receives code for execution. A security manager resides on a server and determines whether to permit the execution of a servlet based on a characteristic of the servlet. The security manager makes this determination by performing a number of security checks implemented as a security policy that is configured based on the servlet's network source.

System and method for securing a program's execution in a network environment

A system and method for securing a program's execution in a network environment is presented. A first server is configured to permit execution of a program from a second server based on a configurable security characteristic of the program. The first server receives the program transferred from the second server. Subsequently, the program is checked for the configurable security characteristic. The program is executed on the first server if permitted by the configurable security characteristic.

A system and method for establishing a peer-to-peer communication connection between computer programs from the same security domain, but executing in first and second computers, is disclosed. A first computer program, while executing in the first computer, sends a communication a message to the second computer, requesting a peer-to-peer communication connection. Upon receiving the message at said second computer, the second computer determines whether a second computer program meeting predefined criteria for establishing a peer-to-peer communication connection is executing in the second computer. If so, the second computer sends to the first computer a reply message accepting the request. After receipt of the reply message by the first computer, the requested peer-to-peer communication connection between the first and second computer programs is established. In a preferred embodiment, the predefined criteria for establishing a peer-to-peer communication connection is that the first and second computer programs be from the same server computer.
