Email is a vital part of every business but it’s also a prime target for common security threats like viruses and malware attacks. A cyber attack could bring your business to a halt, so the importance of a solid cyber security strategy shouldn’t be underestimated.
If you’re concerned about the security of email services in your company, you may wish to engage a cyber security analyst to advise you on aspects such as how to prevent phishing or malware.
But following email security best practices will help to reduce the risk of a cyber attack.
Using an encryption service is a very effective way to improve email security. Encryption will secure your data so that even if it’s intercepted by a hacker, they won’t be able to read it.
Using encryption to tighten up your email server security won’t completely remove the risk of security breaches, but it makes them much less likely.
Malicious links are one of the main email security risks. So if you receive an unknown link, pop-up window or attachment in an email, don’t click on it – it’s safer to assume that they may be malicious.
If you weren’t expecting a link or attachment or aren’t sure why you’ve received it, either go to your browser and type in the address there or check with the sender before you click.
If you only have a single email account then hackers could access all of your data by compromising that account. Running multiple email accounts means that a security breach will only give access to part of your data.
So consider setting up one personal email account for social media use, one for secure financial data and another for personal correspondence. And be sure to have individual accounts for each person in your company so they are responsible for their own data security.
Weak passwords make it easy for hackers to gain access to your emails. Good email security means using passwords with a mix of upper and lower case letters, numbers and special characters if allowed.
Use a different password for each account and use a password manager like LastPass if you can’t keep track of your passwords. You should also change your passwords regularly, and never write it down and stick it on your monitor!
Two-Factor Authentication (2FA) is another way to increase security for email. With 2FA, you will also be asked to provide an additional PIN or a security token from an authenticator, which makes it much harder for a hacker to gain access to your account.
Using free public WiFi can increase the risk of an email security breach. If you need to use email while you’re out and about, it’s safer to set up a mobile hotspot on your phone and tether your device to that.
And you should also be careful where you share your email address. Posting it to public forums or websites can lead to it being added to spam lists so it’s worth setting up a separate email address for this use.
These simple steps can help to reduce the risk of common security threats like malware attacks. For further advice on cyber security services, contact Median IT for advice on email security solutions for your business.
