Testing Your SSL Server for CRIME
We still have to wait for later this week when Juliano Rizzo and Thai Duong will present their CRIME SSL/TLS attack at Ekoparty Security Conference. Regardless, we now know that the attack is based on the implementation of TLS compression or SPDY (pronounced “speedy”). CRIME uses the vulnerability that there is information leakage when data [Read More...]
Stopping CRIME Attacks
This article by Dan Goodin appears to cover the most facts about the CRIME attack on SSL/TLS. It answers my first question about what the acronym means; CRIME is short for “Compression Ratio Info-Leak Made Easy.” It also confirms the attack is performed when the communication uses TLS compression. My understanding is that TLS compression [Read More...]
Speculation on CRIME
The SSL industry is waiting for the Ekoparty Security Conference next week to find out more details on the CRIME SSL/TLS attack. Speculation by SSL/TLS experts? The attack is based on TLS compression. Thomas Pornin made this post on IT Security of his guesses on how compression could be used in an attack. This also [Read More...]
CRIME Attack on SSL/TLS
The security researchers who brought us BEAST now have a new SSL/TLS attack: CRIME. I would like to know what the acronym CRIME stands for, but we’ll probably have to wait until Juliano Rizzo and Thai Duong present their work at Ekoparty Security Conference later this month. Little information about the attack has been published. [Read More...]
SSL News from Black Hat and DEF CON
I like to follow up each year with the SSL news from Black Hat USA and DEF CON 20. I was just looking for my 2011 follow-up and found out that I never released it. Unfortunately, I started the write up just before the DigiNotar fiasco and never finished it. So what SSL presentations occurred [Read More...]
SSL/TLS Deployment Best Practices
SSL Labs has created an SSL/TLS Deployment Best Practices guide. The guide contains valuable information on how to deploy SSL in your environment. The data from SSL Pulse shows us there are plenty of SSL implementations that could be executed more securely. These problems are not from the CA, the certificate, the browser or the [Read More...]
