  • SysAd and SecuritySystems Administration (SysAd) and Digital Security are two huge categories that are both hugely important in the modern world. SysAd ranges from compiling modules, configuring Apache webserver, updating servers and networking remote computers. Digital security, one of the most interesting aspects of the digital world, will see topics for everything from configuring firewalls, detecting security breaches, handling exploits, calculating risk and detecting threat vectors. I’m hugely interested in SysAd and security, as I see them both as critical aspects of entire businesses. Both SysAd and Security Individuals are in a constant arms race with malicious users and automated bot nets. As new tools to protect servers and systems are produced and rolled out, new ways to circumvent them are developed. As hackers find new ways to breach systems and services, security aficionados and clued up  system administrators patch, program and research their ways back to securer grounds.

A blog from a forensic investigator, ethical hacker and programmer

Category: Fixes & Solutions

One of the reasons for me creating this blog is to write up solutions to computer problems I’ve come across. Some fixes are so complex, or are simply stumbled upon, that they don’t have many results in Google. This causes a tiny bug to become a huge source of stress that can last for days. We’ve all been there, so hopefully these articles really help a few programmers or computer users out.
