HiddenWall is a Linux kernel module generator used to create hidden kernel modules to protect your server from attackers. It supports custom rules with netfilter (block ports, hidden mode, rootkit functions etc). The motivation is basically another layer of protection, much like a hidden firewall – setting securelevel to 2 on BSD would have a […]
Windows kernel (is) (, compared to Linux kernel) Image by Nguyen Vu Hung (vuhung) 1. (Frankly) Windows kernel is slowser Especially when running complex workloads that push network/disk/CPU scheduling 2. It seems that Microsoft have ost innovation 3. New algorithm implementation 4. Microsoft never tested I/O schedulers, process schedulers, filesystem optimization, TCP/IP stack tweaks, wireless […]
