Hardly a day goes by without news of yet another major data breach. Every day–every hour–your computers are under attack. Don’t believe me? I run a website, Practical Technology, which is just an archive for my published stories. It’s been attacked so far today, according to WordFence, a top WordPress security program, 29 times today. That’s just my WordPress site. Snort, the open-source intrusion detection system (IDS) tells me my Linux server has been attacked 127 times so far. That’s a lighter than average day.
