Cybersecurity Event Mauritius: Firewalls: back, now, then

Have you missed one of the most important cybersecurity event which recently took place in Mauritius ? I wrote a blog post to announce the event. Well, in case you miss it, you might be interested in this article to catch up with the event. It was publicly announced on the hackers.mu Facebook group as well on hackers.mu Twitter account. It was held on the 10th of September 2017 at Voila hotel conference room at Bagatelle, Mauritius. Several students from University of Mauritius, professionals and members of MOSS - Mauritius Open Source Society were also present on that day.

The hackers.mu team which is the first group of Linux and BSD developers in Mauritius invited Philipp Buehler, an international cybersecurity expert. He spoke about his experience in cybersecurity and gave recommendations for people interested by the the field or just want to learn new skills in that area. He also emphasised heavily on Network and Security infrastructure, Firewalls, IPS, IDS and several other components. You can view the slide here :

It was an open talk. Several topics such as Fragmentations and Protocol issues were tossed from the audience. One of the interesting topic was on IPS - Intrusion Prevent System. Philipp explain how most of the time if wrongly configured the system does not prevent any attack but instead legitimate packets. Typically, since it is an automated system and usually we have Crons which run at night and based upon some patterns by the IPS, same is interpreted as an attack and finally several IPs are banned and finally we land in a debug session. He pointed out about putting it back to an IDS - Intrusion Detection System. Support of IPV6 to several IDS were proposed as one example for University projects. It was amazing how Philipp re-drew the OSI diagram in a practical way and mentioned the "8th layer". Another interesting diagram explaining how the Kernel interacts with the CPU, Memory and Disk to illustrate the Userland, the Kernel and the hardwares.

In case you are looking forward for more security events in Mauritius, please keep in touch on our Twitter Page and Facebook group. The hackers.mu also credits the PHP User Group of Mauritius for its kind sponsorship of the event and credits to Akasha Lilith for the nice pictures taken during the event  🙂
