Endpoint security is the security of physical devices which may literally fall into the hands of malicious users. Given the rapid growth of employees who use laptop computers, securing network endpoints has become of paramount concern for security administrators.
Traditional means of securing the endpoint are going by the wayside. A firewall alone is no longer enough to defend your network from the myriad threats that remote users, malicious hackers and the age of easy-access information have wrought. In the summer of 2006, a laptop containing personal data on nearly 30 million military veterans and active duty personnel was stolen from an employee of the U.S. Department of Veterans' Affairs.
