Looking Back at 2013

Protocol Attacks

The year started with a couple of SSL/TLS protocol attacks: Lucky Thirteen and RC4 attack. Lucky Thirteen allows the decryption of sensitive information, such as passwords and cookies, when using the CBC-mode cipher suite. Lucky Thirteen can be mitigated by implementing software patches or preferring the cipher suite RC4.

Encryption Still Works – It’s About How You Implement It
September 13, 2013 by Ben Wilson ECC Encryption Malware RSA SHA1 SHA2 SSL/TLS TLS 1.1 Vulnerability

The September 5th joint article by the New York Times and Guardian newspapers on NSA’s and GCHQ’s efforts to circumvent encryption implementation have left many people speculating on the security of the data they are transmitting over the Internet. Hopefully, this blog post will provide some guidance and help understand SSL in light of these recent articles. Importantly, the articles point out that the primary means of attacking SSL/TLS do not exploit a vulnerability in the protocol itself but instead aim to exploit poor implementations of the protocol, insecure servers, and weak cryptography.

Getting the Most Out of SSL Part 2: Configuration

They say the most complicated skill is to be simple; despite SSL and HTTPS having been around for a long time, they still are not as simple as they could be.

One of the reasons for this is that the security industry is constantly learning more about how to design and build secure systems; as a result, the protocols and software used to secure online services need to continuously evolve to keep up with the latest risks.

Getting the Most Out of SSL Part 1: Choose the Right Certificate
May 25, 2013 by Wayne Thayer CSR ECC Microsoft RSA SHA2 SSL/TLS

SSL and HTTPS are two of the most common security technologies on the internet today, but at the same time their use can be complex and challenging to get right. Over the next few weeks, we’ll be publishing a series of articles aimed at identifying some of the decisions that need to be made when buying, installing, and using SSL certificates. In this first installment, I’ll discuss some of the issues to consider when buying and requesting a certificate.

All You Need to Know About the RC4 Encryption Scheme
March 14, 2013 by Rick Andrews Attack CASC Encryption RC4 RSA SSL/TLS Vulnerability

The latest published attacks target specific algorithms used within SSL/TLS. Those algorithms are used when a client connects to a server via SSL/TLS; they’re not used when a Certificate Authority signs a certificate. The attacks demonstrate potential weaknesses in the use of the algorithms.

While interesting, the attacks don’t represent an immediate practical threat to users of SSL/TLS (including online banking, e-commerce, social networking, etc.). Such attacks require an attacker to run malicious software on a user’s computer which would connect to a particular web site and send the same message over and over again many times. In fact, if the attacker’s software could send the same message over and over 10 times per second, it would still take more than 3 years for the attack to succeed.

RSA Recap – Securing Your Site

At RSA last week a few of us participated in panel discussions that focused on SSL/TLS. During the panel that I moderated on Friday, one theme we addressed was secure server configuration. One of CASC’s goals is to help harden existing SSL/TLS implementations against vulnerabilities—because most SSL/TLS exploits arise from suboptimal website configurations. These vulnerabilities and attacks can be mitigated or even eliminated with proper server configuration and good website design.

CASC Happenings at RSA

We are excited to have members of the CASC attending and speaking at this year’s RSA Conference. The events and panels will cover various topics that revolve around the security of the Internet and CAs as a whole. You can follow the CASC on Twitter for more information and news at @CertCouncil, as well as see some of the presentations after the events on our SlideShare page. Please join us for the following CASC member events:
