Top Tips for Internet Security at Work


Defend your computer

Strengthen your computer’s defences. Keep all software (including your web browser) current with automatic updating (or follow the directions of IT staff). Install legitimate antivirus and anti-spyware software. Never turn off your firewall.

Don’t be tricked into downloading malicious software. Stop and think before you open attachments or click links in unusual email, text, or instant messages (IM), on social networks, or in random pop-up windows. If you’re unsure if a message is legitimate—even from a co-worker—contact the sender to confirm using a different device and another account.

Protect company data and financial assets

Don’t put confidential information in email, instant, or text messages; they may not be secure.

Beware of scams. Never give information like an account number or password in response to a phone call, or email or other online request.

For the most sensitive transactions—Automated Clearing House (ACH) payments, payroll, and the like—consider a dedicated computer not used for email or web browsing.

Create strong passwords and keep them private

Lock devices, company routers, and online accounts with strong passwords or PINs. Strong passwords are long phrases or sentences and mix capital and lowercase letters, numbers, and symbols.

Don’t disclose passwords or PINs to co-workers.

Use a unique password on each account or device containing personal or business data, and change them regularly.

Guard company data when you’re on the go

Treat all public Wi-Fi networks as a security risk.

Choose the most secure option—it could include password-protection or encryption—even if you have to pay for it.

Confirm the exact spelling of the wireless network you’re connecting to— beware of clever (slightly misspelled) fakes, such as www.micrsoft.com.

Encrypt all confidential data on smartphones, laptops, flash drives, and other portable devices in case they’re lost or stolen.

Never make financial and other sensitive transactions on any device over public wireless networks.

Use flash drives carefully. Minimize the chance that you’ll infect your company network with malware:

Don’t put any unknown flash (or USB) drive into your computer.

On your flash drive, don’t open files that are not familiar
