Analysis of encrypted traffic without decryption

Posted on

A system for analyzing traffic without decrypting it. This method is simply called 'machine learning.' It turns out that if a very large volume of varied traffic is fed into a special classifier, the system can detect the actions of malicious code within encrypted traffic with a very high degree of probability. Network threats have changed and become 'smarter.' Recently, the very concept of attack and defense has evolved.

Web-HighLoad — how we manage traffic for tens of thousands of domains

Posted on

Legitimate traffic on the DDoS-Guard network has recently exceeded one hundred gigabits per second. Currently, 50% of all our traffic is generated by client web services. This encompasses tens of thousands of domains, which are very diverse and, in most cases, require a personalized approach. Below, we explain how we manage front nodes and issue SSL certificates for hundreds of thousands of sites. Configuring the front for a single site, even one that is very […]

Implementation of the high-security remote access concept

Posted on

Continuing the series of articles on organizing Remote-Access VPN access, I cannot help but share an interesting experience of deploying a highly secure VPN configuration. One client posed a non-trivial challenge (there are quite a few imaginative thinkers in Russian villages), but Challenge Accepted—creatively implemented. The result is an interesting concept with the following characteristics: Several protective factors against device impersonation (strictly tied to the user); […]
