User and sysadmin mistakes allow intruder access in most cases

Recent studies from Verizon and Symantec show that malicious hackers almost always gain unauthorized access to computer systems because of misconfigured software and user errors. You don’t have to be a genius hacker to get into a supposedly secure system if a sysadmin left the door wide open, or if you can fool a gullible user into revealing their password.

As a user, you’re probably getting tired of being told to be careful when clicking links on the web and in email. But it’s good advice. If you receive an email message that includes a link, and tells you to click the link, think before you click. If someone asks you for your password, do not give it to them.
