What is email security?
How secure is email?
Email was designed to be as open and accessible as possible. It allows people in organizations to communicate both internally and externally. The problem is that email security on its own is not reliable. Whether through spam campaigns, malware and phishing attacks, sophisticated targeted attacks, or business email compromise (BEC), attackers try to take advantage of this lack of security to carry out their actions. Since most organizations rely on email to do business, attackers exploit email to steal sensitive information.
Because email is an open format, it can be viewed by anyone who can intercept it. This is an issue when organizations send confidential or sensitive information through email. Attackers can easily read the contents of an email by intercepting it. Over the years, organizations have been increasing email security measures to make it harder for attackers to access sensitive or confidential information.
Email security best practices
1 - Implementing a secure email gateway:
An email gateway scans and processes all incoming and outgoing email. It ensures that threats are not allowed in. As attacks are increasingly sophisticated, standard security measures such as blocking known malicious attachments are no longer effective. The current solution is to deploy a secure email gateway that uses a multi-layered approach.
Mailscreen is the #1 service for this purpose.
2 - Automated email encryption:
This solution should be able to analyse all outbound email traffic to determine whether material is sensitive. If content is sensitive, it needs to be encrypted before it is emailed to the intended recipient. This will prevent attackers from viewing emails, even if they were to intercept them.
3 - Implementing a DMARC policy for your domains
Ensuring that your domains are protected from abuse for outbound emails as well as increasing the email deliverability for your trusted sending sources. Without the implementation of DMARC policy you have no insight into how your domain names are used and potentially abused for outbound email purposes.
4 - Display your logo for email sent to from you
With the implementation of BIMI together with DMARC and VMC you increase the email security by clearly showing the recipients that emails originate from you. As the recipient sees your logo in their email before they have opened it, they can be confident that the email is not fraudulent.
