📕📕 (𝐒𝐞𝐥𝐟)𝐋𝐞𝐚𝐫𝐧𝐢𝐧𝐠. 𝐑𝐞𝐬𝐞𝐚𝐫𝐜𝐡, 𝐟𝐚𝐜𝐭𝐬 𝐚𝐧𝐝 𝐛𝐞𝐬𝐭 𝐩𝐫𝐚𝐜𝐭𝐢𝐜𝐞𝐬

Dear friends, I'm pleased to present to you the translation of my author's brochure (e-book), which I completed in December 2023. Initially, the brochure was available only in Russian language. This work is not a commercial project for me, so I don't have proofreaders, professional translators or editors on my staff. The brochure was translated using artificial intelligence with minimal manual correction. So, for this reason minor errors are possible.

However, I hope that the importance of the material will outweigh all the errors and shortcomings of the translation🤝

➡️𝐁𝐫𝐢𝐞𝐟:
The brochure has incorporated modern scientific and empirical research on the topic of learning (acquiring knowledge, skills, assimilation of information, memorization, speed reading, etc.) and self-learning, theories and facts, including the latest discoveries in the field of psychology, neurophysiology, pedagogy, linguistics, the author's own research in understanding human cognitive abilities.

How to Start Your Own Cybersecurity Consulting Business: First-Hand Lessons from a Burned-Out Ex-CISO, Ravi Das (, 2023

How to Start Your Own Cybersecurity Consulting Business: First-Hand Lessons from a Burned-Out Ex-CISO, Ravi Das (, 2023

The burnout rate of a Chief Information Security Officer (CISO) is pegged at about 16 months. In other words, that is what the average tenure of a CISO is at a business. At the end of their stay, many CISOs look for totally different avenues of work, or they try something else – namely starting their own Cybersecurity Consulting business. Although a CISO might have the skill and knowledge set to go it alone, it takes careful planning to launch a successful Cyber Consulting business. This ranges all the way from developing a business plan to choosing the specific area in Cybersecurity that they want to serve.

The book is written by an author who has real-world experience in launching a Cyber Consulting company. It is all-encompassing, with coverage spanning from selecting which legal formation is most suitable to which segment of the Cybersecurity industry should be targeted. The book is geared specifically towards the CISO that is on the verge of a total burnout or career change. It explains how CISOs can market their experience and services to win and retain key customers.

Trinity uses nmap in "The Matrix Reloaded" movie, Wachowski brothers, 2003

That's exactly how the fictional Trinity uses it. In a sequence that flashes on screen for a few scant seconds, the green phosphor text of Trinity's computer clearly shows Nmap being run against the IP address 10.2.2.2, and finding an open port number 22, correctly identified as the SSH service used to log into computers remotely.

"I was definitely pretty excited when I saw it," says "Fyodor," the 25-year-old author of Nmap. "I think compared to previous movies that had any kind of hacking content, you could generally assume it's going to be some kind of stupid 3D graphics show."

Discovered in February, 2001 by security analyst Michal Zalewski, the SSH CRC-32 bug is a very real buffer overflow in a chunk of code designed to guard against cryptographic attacks on SSH version one. Properly exploited, it grants full remote access to the vulnerable machine.
