System Safety Monitor (SSM) is a ‘Host Based Intrusion Prevention System’ (HIPS) software. The main purpose of this program is to discover and block malicious actions of any application. It keeps your system extremely secure by providing protection against attacks that a traditional firewalls and anti-virus software can by-pass. However SSM is not an anti-virus software.
SSM keeps track of all the activity of applications (started or being started) and allows you to control, such as which application can be started, whether a selected application is allowed to install a driver, whether a selected application is allowed to perform code-injection or DLL-injection, etc.
It provides tracking and blocking of changes in Windows Registry; drivers and services; INI-files; Startup menu group, Internet Explorer settings and application's windows also.
However, SSM is not an easy to understand program for a beginner is concerned. It asks you about every program that is trying to launch either by you or automated by the system. Moreover it does not help the user in anyway by advising which application should or should not be allowed.You can download this free program from developer’s homepage.
