So, I discovered that it's customary to give an #introduction on #mastodon so here I am.

I'm @shalien , a computer enthusiast as #dev as #network .

Disappointed with Twitter / X , I resurrected my #mastodon instance and here I am.

I hope to discover something else, something healthier and more relaxing than the permanent chaos of Twitter.

Looking forward to seeing you in the #Fediverse!

🔍 This video explores the challenges of using network #monitoring tools like #Suricata in today’s encrypted environments.
In the past, packet sniffing was simpler because most #network traffic was #unencrypted. Tools could easily inspect everything from IP addresses to the full content of communications.

A set of patches from Google engineer Eric Dumazet, merged via the networking pull request for the Linux 6.18 will help servers better cope with distributed denial of service DDoS attacks #Network #Linux https://www.phoronix.com/news/Linux-6.18-DDoS-Improvement

#Tor #browser's great - but for more complete #privacy protection, you need to add this. When you use the Tor Browser, the only #network traffic that's being masked is via the web browser. If you want more traffic anonymized and encrypted, you need to take a different approach.

The #SecretService found & seized an illicit #network of sophisticated equipment in the New York region that was capable of shutting down the #cellular network as foreign leaders prepared to gather nearby for the annual #UNGA, the agency announced on Tuesday.

Officials said the anonymous communications network, which included >100k SIM cards & 300 servers, could interfere with #emergency response services & could be used to conduct encrypted #communication.

One official said the network was capable of sending 30 million text messages per minute, anonymously. The official said the agency had never before seen such an extensive operation.

There is no specific information that the #network, now dismantled, posed a threat to the conference itself, #SecretService officials said, speaking on the condition of anonymity to discuss an ongoing investigation. The agency leads the #security for the #UN meetings this week.
