If you're using the computer at work, you probably think it's safe, with firewalls, email filters, anti-virus software, and malware scanners, you're protected, right? Wrong! Because the one thing IT can't protect you from, is yourself. Human error is the biggest cause of cyber intrusions. People clicking on fake links, being taken in by scam emails and using lax security, are all ways hackers get into your machine. And once they're inside your company's network they can do all kinds of damage. Like lock up the server with ransomware or harvest sensitive information. It's up to you to practice good security and help keep your company network safe. Here's how. First, use a passphrase on your machine. A selection of random words like "butterfly, branch, sky, balloon." The usual one-word passwords with numbers and symbols are difficult to remember and easy to hack. A passphrase is easy to remember. You remember "butterfly, branch, sky, balloon," right? And much, much harder to hack. Secondly, use a password manager to handle your online passwords. Using the same password on different sites multiplies the damage a hacker can do. And a password manager remembers different passwords for you. If possible, set up two-factor authentication, too, where you have to use a password and enter a code sent to you by text or email. Always set your computer to lock if it's idle for more than a few minutes If you use a laptop, never leave it unattended in public. And only connect to wifi networks you trust. Hackers use unsecured networks to hijack information. Next, beware of emails. One of the most common ways hackers get into systems is through links or attachments that download and install software when you click on them. Check the email address of the sender. Look out for poor spelling and grammar. And hover over any links before clicking on them to see where they're actually going. It might not match the text. Don't open any attachments you're not expecting. Viruses and malware are often hidden inside attachments. If an email asks for money or any financial information, confirm with the sender by text or phone before replying, to make sure it's legit. Finally, back up your work regularly, ideally in a secure cloud service. This way, if all else fails and your system is infected with ransomware, you can revert to the backup. So, remember, use a passphrase on your machine and a password manager online. Set your machine to autolock and don't leave it accessible in public. Be smart about emails, especially links and attachments. And back up your work. Keep yourself safe, and your network secure. © 2022 Mind Tools by Emerald Works Limited.
