The attacker creates a valid session id: He loads the login page of the web application where he wants to fix the session, and takes the session id in the cookie from the response (see number 1 and 2 in the image). He possibly maintains the session. Expiring sessions, for example ever...
presented on the topic of building Systems. One aspect of his presentation that really struck a chord with me was around the competing desires while designing and delivering an application. This blog entry is about summarizing that aspect and what I took away from it.** Stefan noted t...
I relate to your testimonial here, as I do believe it’s the most accurate description of how to achieve proficiency at something. Another fellow programmer gave his opinion on the matter, and I would like to reproduce my comment on his post here: This discussion about “Inate Talent” v...
You want to do quick messaging between hosts, processes, or even threads. You want to use a different transport besides TCP: multicast, in-process, inter-process. The code doesn't change (besides the bind/connect calls). You want to take advantage of other ZeroMQ messaging patterns to...
