Immunity El Jefe

Immunity's open source project, El Jefe (pronounced 'ell-HEFF-ay') is a Windows based process monitoring solution. El Jefe produces a unique view into how processes are created, what privileges they possess and what child processes they spawn. All of this information is stored, and categorized into a central logging server, which allows a user to quickly see any suspicious behavior that could indicate compromise or malware proliferation.
