Back Door Magazine Issue 7
Cybersecurity is one of the leading topics of our day. Developments are progressing at a dizzying pace. I don't have time to follow all the events, do you wish someone would follow up on our behalf and provide a summary? Tayfun Özkara has been following the events for you with his Cyberspace column since the 7th issue and reporting from the scene. Hacker, journalist and digital rights activist Julian Assange was forcibly removed from the Ecuadorian Embassy where he had been staying for 7 years with refugee status. Although everyone knows him with Wikileaks, Assange is both a digital sage and a talented hacker behind his journalist identity. Would you like to read about Assange from Cansu Topukçu's pen? Passwords are the key to the empire. We protect our most important data, our digital assets, with passwords. We have been recommending some precautions regarding passwords since the first issue. Our most important warning is to use different passwords on different platforms and enable two-step verification. Using different passwords on each platform? So how will you remember these passwords? Of course, by using a password manager! Huriye Özdemir examined the pros and cons of password managers for you. Today, almost all services use end-to-end encryption. Therefore, even if they store this data on their servers, they cannot read it and cannot share it meaningfully with official institutions upon request.

In today's world where everything has a digital face, asking "can ships be hacked?" by excluding the magnificent vehicles of the waters, ships, must be one of the most up-to-date examples of the art of clairvoyance.

Mithat Göğebakan shares a roadmap on client-side code analysis in web applications. Finding the treasure, of course, depends on the sharpness of the readers' attention.
