"When the mobile worker returns to his office and connects to
the corporate network, a compromised laptop can spread malware
throughout the organization or cause a company-wide security

"Fifteen years ago the floppy disk was the most common vector
used by malware writers to spread viruses, and in more recent years
email has been the primary vector. But the trend now seems toward
spreading malware and exploiting vulnerabilities using malicious
code on websites which exploit browser vulnerabilities. According
to IBM Internet Security Systems X-Force team 2008 Trend & Risk
Report "the number of vulnerabilities affecting Web applications

Web server applications accounted for 54 percent of all
vulnerability disclosures and were one of the primary factors in
the overall growth of vulnerability disclosures during the
year."
