Email Encryption Tactics to Keep Messages Safe

Protect Your Communication With Email Encryption

Email encryption is paramount in today’s online heavy-transaction based world. Now more than ever, we are sending sensitive information over the internet to third parties for numerous reasons. The easiest, most convenient way to do this is over email. What most people do not understand is that malicious actors have the ability to capture this email communication and extract the contents (very easily).

A great example is, let’s say you’re using the guest WiFi at a local coffee shop. You construct an email to send an updated copy of your company bank statements to your accountant. Meanwhile, on the other side of the coffee shop, a hacker is sitting there sniffing the WiFi track with free, open source software that is used to capture all the contents of your email. Five minutes later, the hacker is now attempting to brute force login to your bank account because he has your account number. All this can happen within a matter of minutes, without you even knowing. This is why email encryption is vital to both personal and business use cases alike.

To combat this common means of data breach, IND Corporation specializes in data and email encryption techniques. Email encryption encapsulates your email in a package and uses an encryption key to jumble up all the contents so it is unreadable, unless you have the key.

Common Email Encryption Techniques

There are several different ways to handle key exchanges between you and your intended party as well as several ways to encrypt the data. The key is to implement a system that allows both the sender and the recipient to easily encrypt and decrypt emails to keep disruptions to a minimum.

PGP: Pretty Good Privacy

PGP is a hybrid approach. This technique compresses the text, saving disk space and increasing security. Compressed information is much harder for a hacker to read. This tactic also uses a session key, a one-time use secret key. The recipient of the email uses the private key to retrieve the session key, and then PGP decrypts the code to the verified reader.

S/MIME: Secure Multi-Purpose Internet Mail Extension

S/MIME utilizes a digital signature along with the encrypted code to secure emails. With each sending email, a digital signature is added based on the sender’s unique information. When someone attempts to read the message, the signature on the message must be compared to the signature on the receipt before verification is granted.

TLS: Transport Layer Security

Transport Layer Security is focused around privacy and data integrity. TLS is successful by utilizing a shared secret that is agreed upon during a phase called the TLS handshake. Think of this as an agreement to how the client and web server plan to communicate. To add even more security to TLS, a message authentication code can be inserted and used as an integrity checker to ensure the message has not been altered in any way.

At the end of the day, let the professionals at IND Corporation help implement the best type of email encryption for your specific, unique business situation.
