It's been quite some time since my last entry, my bad. Job has taken so much time from me. Anyways, i promised to talk about the Unicage method, and should do it soon. The last great thing related to OpenBSD i've done lately was to create a chroot directory bounded to a ssh user which becomes unable to use any commands upon authentication, very cool.
Today i have gone to a close Educational Institute from "Instituto Janela Para o Mundo" I was there to support a network engineer on installing a new Network Switch. It was fun. This is the first time in my life i ever put my hands in an actual Switch, but it took quite long to install the new hardware.Btw, i need to talk about the Unicage Method, on the next entry i'll be talking about it.
Lately i've been quite interested on BSD systems. On the last weeks, quite some LPE vulnerabilities have been found on the Linux Kernel: Copy Fail, Dirty Frag, Pedit COW, Dirty Clone, Ghostlock. I honestly think this is bad. So, i decided to give a try to BSD systems, mostly OpenBSD and FreeBSD. Reading about OpenBSD i found about pledge, unveil, secure levels, W^X, KARL and many other interesting features!
Well, i guess this is the first of many of my notes
