Enhanced Security: AES-256 Encryption for SSL and TLS

Tuesday, December 1st, 2020

AES-256 EncryptionSSL and TLS play critical roles in securing data transmission over the internet, and AES-256 is integral in their most secure configurations. The original standard was known as Secure Sockets Layer (SSL). Although it was replaced by Transport Layer Security (TLS), many in the industry still refer to TLS by its predecessor’s acronym. While TLS can be relied on for securing information at a high level—such as US Government TOP SECRET data—improper or outdated implementations of the standard may not provide much security at all.

Variations in which cipher is used in TLS impact how secure TLS ultimately is. Some ciphers are fast but insecure, while others are slower, require a greater amount of computational resources, and can provide a higher degree of security. Weaker ciphers—such as the early export-grade ciphers—still exist, but they should no longer be used.

The Advanced Encryption Standard (AES), is an encryption specification that succeeded the Data Encryption Standard (DES). AES was standardized in 2001 after a 5 year review, and is currently one of the most popular algorithms used in symmetric-key cryptography. It is often seen as the gold standard symmetric-key encryption technique, with many security-conscious organizations requiring their employees to use AES-256 for all communications. It is also used prominently in TLS.

The Case For Email Security

Tuesday, March 31st, 2015

We all know that regular email is insecure; however, it may surprise you to learn just how insecure it really is. For example, did you know that messages which you thought were deleted years ago may be sitting on servers half-way around the world? Or, that your messages can can sometimes be read and modified in transit, even before they reach their destination? Did you know that forging email is very, very easy?  Can you trust what you read in an email?  Email security was never designed in to the internet from the beginning and as a result, many different solutions have evolved to plug the multitude of resulting issues.

This article is designed to teach you about how email really works, what the real email security issues are, what mitigations to these are generally in use, and what else you can to to protect you email.

Case for Email Security

Information security and integrity are centrally important  as we use email for personal and business communication: sending confidential and sensitive information over this medium every day. While you are reading this article, imagine how these security problems could affect your business, your personal life, and your identity…. if they have not already.
