As you know, I landed this thursday at Coruña and on friday I was teaching at Master on Free Software the last security networking lesson. With this lesson we finished our first security block. This time we finished with a full laboratory covering practical corporative firewalling and a real web hacking session.

We played a dynamics group too where we were talking about security industry and how it impacts our enterprises and organizations. In particular we spoke about adding effective countermeasures in your organization/business, our current security situation, being productive with open security tools, handling vulnerability responsible disclosure or the new vulnerability markets among other topics.

We close this master class answering doubts and sharing our opinions and ideas about effective security.

Now, people attending those classes know about tactics and tools used by blackhats while breaking in real targets. We focused on different topics such as design flaws, protocol weakness, hijacking connections, fragmentation attacks, active/passive fingerprinting, switched sniffing, MITM attacks, advanced scanning and so far.

The next master class, scheduled on the 18th/July, we’ll see advanced and strategic defense for organizations. Among the practices we’re going to analyse real attacks and play dynamics group.

By the way, I’m blogging from Istanbul … see you guys at GUADEC!
