ALT Linux powers the Internet, and most webservers, databases, and even super-computing clusters today run on it. This means that our valuable, sensitive, and personal data is likely to be stored on a device running Linux. Unfortunately, our adversaries know this. Attacks against Linux platforms are increasing, so responders need the tools and techniques to combat them.
