ላለፉት በርካታ ዓመታት ውስጥ ይህንን ብዙ ጊዜ ሰምቻለሁ: አንድ ሰው በድር ጣቢያቸው ላይ ከባድ ዲዲኦ ጥቃቶች እያጋጠመው ነው. When I ask them what type of attack they are experiencing, the answer is usually that the bad guys are sending them thousands or even millions of POST requests. When I…

For many years, I zealously have used Suhosin with any implementations of PHP5 on Apache2 or PHP-FPM Nginx webservers to defend against SQL injection and other common web attacks. In fact, PHP5 was so disastrous, both in terms of its core security, and its functions and modules that I could have never conceived using it…
