Telegram’s description of DDoS attack is the best

The servers of Telegram, a popular instant messenger, were under a DDoS attack recently. While they were working on the problem, they’ve tweeted a couple of explanations of what’s going on. CNET brings those tweets to our attention, as they explain rather complex things in a very short and simple way.

Internet Trends 2019 (Bond Report)

Internet Trends 2019 report is the most comprehensive, detailed, and research document that I have ever seen on what’s going on with the Internet, web, mobile, social media, marketing, and security.

This year’s report spans 333 pages and is full charts, graphs, statistics, insights, and references. And if you are feeling nostalgic, there is an archive of the annual reports going all the way back to 1995.

It’s difficult to pick a single fact from such a huge document, but if I had to, I’d go with this:

51% of the global population, or 3.8 billion people, were Internet users last year.

Wow. That’s quite a crowd.

Ansible + AWS + GraphViz = aws-securitygroup-grapher

aws-securitygroup-grapher is a handy tool that can generate a variety of graphs visualizing Amazon Security Groups. It is implemented as an Ansible role and uses GraphViz to produce the results.

This is particularly useful when you need to get familiar with a complex VPC setup by someone else, or when you want to review the results of an automated setup. – HTTP/HTTPS troubleshooting and profiling tool is a handy command-line tool for HTTP/HTTPS troubleshooting and profiling. It also integrates with a number of other security tools, like nmap, SSL Labs, subfinder, etc.
