What are the different ways to secure your email and email users?
As well as implementing security packages, good security practices and policies for your staff are also essential in securing your email communications.
Network security systems, that can protect the business as a whole, are also worth considering as these can help to block hackers and identity theft.
What email security settings should you use?
Make sure you use a spam filter, and scan your email attachments. Research has shown that nine out of every ten viruses that infect a computer reach it through an email attachment.
Instant messaging protection and email spyware protection are also available with many security software products, as are personal firewall tools, which come with the operating system and with many security suites.
Identity protection and content blocking can also go some way to help protect the user’s desktop, so ensure that these settings are optimised.
Can I encrypt my emails?
Lawyers and accountants are key users of email encryption software, which often comes as a hosted service or plug in module for Microsoft Outlook.
Email encryption technologies exist to protect individual sensitive emails. Software such as OpenPGP allows you to encrypt emails between the sender and recipient, to boost the security of the emails.
Email encryption uses a public key encoding system which has been termed military grade security because it is so hard to compromise.
What email security policies should I have?
Most businesses have trained their staff in the basic email usage rules and best practises, such as not opening emails from unreliable sources or clicking on web links in emails that you can’t trust for sure.
However, there are also other good usage policies that can help to secure your email and the business as a whole.
These include such things as using the bcc option with integrity, so that spammers do not get hold of large lists of names. Judicious use of the Forward and Reply All buttons are two other practises that can help to secure business communications.
It goes without saying that email and PC logins should be based on strong passwords, rather than ones that are easy to guess. Passwords should be changed regularly to maintain security, and never shared or displayed indiscreetly.
