Honeypot vs Deception using Xello as an example

Posted on

There are already several articles on Habr about Honeypot and Deception technologies (1 article, 2 articles). However, we still encounter a lack of understanding regarding the difference between these classes of protection tools. For this reason, our colleagues from Xello Deception (the first Russian developer of Deception platforms) decided to thoroughly describe the distinctions, advantages, and architectural features of these solutions.

A Hole as a Security Tool – 2, or How to Catch APT 'Live'

Posted on

(Thanks to Sergey G. Brester for the title idea) Colleagues, the goal of this article is to share our experience from a year of testing a new class of IDS solutions based on Deception technologies. To maintain the logical coherence of the material, I believe it's necessary to start with the premises.

Immensely attractive: how we created a honeypot that can't be exposed

Posted on

Antivirus companies, cybersecurity experts, and simply enthusiasts post honeypot systems online to 'catch' fresh strains of viruses or detect unusual hacking tactics. Honeypots are so common that cybercriminals have developed a kind of immunity: they quickly recognize that they are faced with a trap and simply ignore it. To study the tactics of modern hackers, we created a realistic honeypot that […]

Why don't the letters in EBCDIC appear consecutively?

Posted on

The ASCII standard was adopted in 1963, and it is unlikely that anyone still uses a character encoding where the first 128 characters differ from ASCII. Nonetheless, until the end of the last century, EBCDIC was actively used—the standard encoding for IBM mainframes and their Soviet clones ES EVM. EBCDIC remains the primary encoding in z/OS, the standard OS for modern mainframes […]
