It's easy to imagine the hackers attacking your network as a team of computer masterminds. But in reality, the vast majority of data breaches don't occur from some genius hacking into the mainframe. According to Trace Security, a full 81% of breaches happen as a result of poorly constructed passwords.

Luckily, avoiding this is pretty simple. Ensure every member of your team uses strong passwords, over eight characters in length and comprised of letters, numbers and symbols. Keep the numbers and symbols away from each other, and definitely avoid the common, obvious passwords like "123456789" or "password." You also might consider implementing two-factor authentication in your system, which is several degrees of magnitude more secure than ordinary passwords, but it can be a headache to set up without an expert on your team.
