Corporate Mail Security. Tips and Guidelines

Corporate or business email has become an indispensable tool for communication in any company or administration, both within the organisation itself and with customers and partners. Security in corporate or personal email must also be a priority.

Cyber criminals have also detected that business mail is a strategic working solution that is fast, accessible, does not require large investments, increases availability and presence, is configurable and allows documents to be sent to multiple recipients. For this reason, it did not take long for different breaches or cyber-attacks to be carried out on companies, organisations and administrations through corporate mail.

Unitel- Sistemas de Telecomunicaciones shares a series of security tips and guidelines to take into account when using corporate mail. The aim is to protect us from possible fraud, malware, viruses, spam, phishing attacks, chain messages, password theft, scams or computer infections.

Corporate Email Security Guidelines Beware of opening emails from unknown senders or untrusted addresses. Be wary of emails and attractive messages that arrive in your inbox with gifts, offers, promotions or urgent messages. Remember that banks do not ask for personal or confidential information by sending e-mails. If in doubt, always check with your bank. Do not execute or download the attached documents. It is possible that the file that accompanies the email hides malware and could infect your computer equipment. We advise you to use your antivirus to scan any attachments you receive from unknown or unsafe e-mails beforehand. Forget about automatic downloading of images accompanying the email and avoid clicking on internal links in the body of the message without confirming that the URL matches the proper address. Spammers nowadays use images attached to the body of the message to bypass spam filters. Don't fall into the trap of replying to spam or clicking the 'unsubscribe' option. This is the spammer's way of confirming that your corporate email account is active. Learn to recognise phishing. An increasingly common malpractice that affects corporate email security. This is crimeware that impersonates and falsifies a website to obtain personal data, bank details or passwords for financial gain. Don't forget to delete cached data, browsing history, cookies or temporary files on a regular basis. Especially if you have accessed corporate email from computers outside the company. Avoid automatically saving passwords and never share passwords. In addition, use complex, strong and secure passwords and change them regularly. A strong password is considered to be one that is made up of more than 8 characters with upper and lower case letters and numbers. Use different corporate email accounts for the different services of your company, with different passwords for each of them. We also advise you to have alternative or even temporary email accounts for registration or for browsing less secure sites. The aim is to protect and ensure the security of your corporate email. Do not access your corporate email on other people's or public computers. Of course, avoid accessing corporate email through public wifi connections and networks, as you may be more exposed to password and personal data capture. Join corporate email when you are connected to a trusted network and always log off. One of the benefits of corporate email is being able to send emails and documents to many recipients. Don't forget to use the Bcc option. It's a way to ensure the security of corporate email from other companies and customers and to protect recipients' addresses from being spammed. Opting for an encrypted corporate email solution would allow you to control the sending of all your confidential information and improve your company's image in terms of information security. You can also opt to send compressed and encrypted documents, preventing mail from travelling 'in the clear', i.e. confidential content can be easily read. You can check with your service provider about the availability of these products. Don't forget to update your computer operating system and software, as security improvements are included in the updates. Install anti-malware applications and enable spam filtering. This is a basic necessity for personal email use. However, for any company or administration, it is essential to have an anti-malware solution and anti-spam filtering, which allows employees to scan incoming mail and reject and block junk mail. It is possible that this option is included directly in your installed antivirus. Limit the use of corporate email to business purposes. With this action we avoid coming into contact with possible spammers, being victims of cyber-attacks or putting the security of our corporate account at risk. Many workers forget that corporate email is a work tool and use the business email account for personal purposes.
