  • 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.
