Hey there, I’m not Dead Yet “Port Knocking” !!!
By Ali Hadi, Information Security Researcher
For a glance people might think ”hey, what’s this guy talking about; Port-Knocking is dead!”. Even though new security solutions have arised, the Port Knocking concept has not died or become extinct. In my opinion, Port Knocking is an amazing concept which can still be used to secure our public services. Port Knocking not only can add security to poor written or unsecured services, but add another layer of security to services that were already built with security ideas in mind.

Deeper Inside the Network
By Yehia Mamdouh, CCNA, CEH
When hackers attack a certain network for information leakage or certain damage, the main target for them is usually a network server. Essential for the attacker is network mapping and a sound plan of how what and when to attack. Problem is that Network servers cannot be attacked directly. You should rather attack a vulnerable client in the network and then from there attack the server. This technique is commonly called Pivoting and we are going to show you how to use that technique which can be done for example with Metasploit.

The Importance of Cryptography and Security Experts in Society
By Rafael Fontes, Co-Founder at Grey Hat and member of “French Backtrack Team”
The hacker culture and resulting philosophy is a dynamic one and changing over the decades, an everlasting ongoing evolution. It’s true that hackers/security researchers not only contribute to a safer digital presence but also stand at the beginning of the newest technological developments. The true pioneers. The security industry versus crackers (cyber criminals) ratrace is just a spin off. The term hacker has more to it than the avarage public opinion reveals. The whole hacker landscape (blackhat, greyhat, whitehat, bughunter, researchers, academics..) and any mix is of imminent importance. And not only the Brazilian corporations appreciate their involvement for the good or worse.
