Operating System Hardening is an essential security strategy positioned between the network and application. One of popular server OS - Unix is a multi-user system, which could support over hundreds of users with different directories and database applications. Unix is less secure than other proprietary operating systems as its public-domain variants are particularly vulnerable. That's is why hardening Unix is becoming essential parts of each organization. HiTRUST provides UNIX Hardening service to minimize servers' exposure to current and future threats on this computer platform by fully configuring the operating system, removing unnecessary applications and apply security-related patches offered by your vendor.

Hardening Unix server raises the bar on the level of skill and effort needed to crack into system, thus discourages joyride attackers looking for an easy target. HiTRUST also helps to log all network-access hacking attempts to the Unix server, both successful and unsuccessful. By logging suspicious network activity, an organization can stop would-be attackers from breaking into the system; more importantly, the organization can trace (and sometimes identify) successful attackers.

Common hardening task aims to protect system against:

	Denial-of-service attacks
	Brute-force attacks
	Social-engineering attacks
	Passive attacks
	Malicious local users
	Legitimate users' clumsiness
	Software bugs, etc.
