It's hard to believe email wasn't even a concept 20 years ago. Now, it's beginning to replace physical interactions in the business world. However, this means that it's extremely important to keep your email protection measures updated.

Here are some tips for keeping email services secure in a company setting:

1. Be smart about the information shared
McAfee recommended being aware of what information is sent through email. The source emphasized that even if there's top security on one person's machine, if data from there is sent to an insecure computer, it's still at risk of being compromised. Sensitive information such as credit card data or any other private material should not be sent through email. Email encryption between two computers can protect this kind of information, but only if both parties have encryption.

2. Don't click links or open attachments
Makeuseof discussed ways to protect electronic data through email, and pointed out that many people are tempted to click links within emails. This is a bad idea, as the links may be malware or viruses. Unless a worker is expecting a specific email that would include a link, such as a website registration, messages with links should be approach with caution. This also goes for unsolicited attachments. An expected attachment from a colleague is probably safe, but if it's from an unknown sender, the email should be deleted.

3. Avoid public Internet
Open Wi-Fi is a difficult temptation to avoid, but everyone should try to not check their email on it. Public Wi-Fi is becoming more common, but it has proven to be very insecure, according to Makeuseof. The source discussed "network sniffers," which are programs that run on hackers' devices and monitor wireless data within a network. They're capable of discovering usernames and passwords to things like your online bank account or email.

4. Keep it complex
McAfee recommended creating strong passwords and complex usernames. It's becoming easier for hackers to generate automated spam and other attacks due to weaknesses in this regard. No matter how smart a password is, it should always be updated regularly, so making this a company policy is a good idea. Passwords should have a mixture of numbers, special characters and capital and lowercase letters.

These tips are great to give to employees who are new to the various threats in the cyberworld. Using email daily can be a risky action if not done right, which is why workers of any company need to be sure to keep updated on email security basics.
