VoLTE and SRTP
by Michael Thomas 09 Mar '22

09 Mar '22

Hi, I was reading an article on why Russia hasn't taken out Ukraine's mobile networks and one of the premises was that they could use it to eavesdrop on calls. Depending on how old their infrastructure is, that doesn't make sense as I would assume that along with e2e SIP that they'd be using SRTP with the SRTP keys exchanged using DTLS which is my understanding of the way they are secured. My understanding could be wrong though, or either outdated, or not uniformly deployed. The other thing that's weird is that the same article says they want to keep it up so they can use their bandwidth too which strikes me as sort of a crazy assumption in a war, but that's not much of an operational issue. https://www.politico.com/news/2022/03/07/ukraine-phones-internet-still-work… Mike

Fwd: Upwork Suspending Operations in Russia and Belarus
by Callan Banner 08 Mar '22

08 Mar '22

Nanog to suspend work in Belarus and Russia. How do you all feel about this? Senseless antagonization or correctly applied pressure? ---------- Forwarded message --------- From: Hayden Brown, Upwork President & CEO <upwork(a)t.upwork.com> Date: Tue, Mar 8, 2022 at 12:51 PM Subject: Upwork Suspending Operations in Russia and Belarus To: <me(a)callan.im> A message from our CEO [image: Upwork] <https://link.t.upwork.com/ls/click?upn=VqS90m2f8fx8n-2F1K6AZcGXfLgLUteWUSWn…> Dear Callan, As the world’s work marketplace, Upwork’s mission is to create economic opportunities so people have better lives. In our more than 20 years of doing business, we have worked hard to bring our marketplace to more people, with the belief that when people have the ability to innovate their careers and work, they can reach their full potential. Russian President Vladimir Putin’s war against Ukraine has challenged our mission, values, and our operational ability to bring economic empowerment to those who seek it. *Upwork has begun suspending operations in Russia and Belarus and will take full effect by May 1, 2022.* The first step will be shutting down Upwork’s support for new business generation in Russia and Belarus. Over the next few days, freelancers and clients in Russia and Belarus will no longer be able to sign up for new accounts, initiate new contracts, and be visible in search. We honor the relationships that exist between our customers and recognize the swift adjustments that they will need to make as they process this announcement. As such, existing contracts with talent and clients in the region will remain open, with final billing due by May 1, 2022. We made this decision with the utmost consideration. From the beginning of the war, Upwork has been fervently working to support the safety, security, and well-being of our many team members in the region, as well as the business needs of our customers. We fully understand the significant impact this decision has on our Upwork community in Russia and Belarus, and we want these customers to know that if and when they are able to relocate to regions where we operate, we will be eager to support them in continuing their work on our platform. Additionally, should the geopolitical situation in Russia and Belarus change, we hope to be able to resume operations. We are heartbroken and horrified by the invasion of Ukraine. Upwork is concurrently working on measures – both immediate and rolling out soon – to further support Ukrainian freelancers and the Ukrainian community, including: • A $1 million donation to Direct Relief International <https://link.t.upwork.com/ls/click?upn=VqS90m2f8fx8n-2F1K6AZcGWG3CACp-2BoZj…> in support of the Ukrainian population. • Product enhancements to make it easier for Ukrainian freelancers to preserve the careers they have worked so hard to establish, whether or not they are currently able to work. • Programs to make it easier for clients to maintain their existing relationships with and provide financial assistance to talent in Ukraine. • A $100,000 matching program for donations from our own team members to aid in humanitarian relief in Ukraine. While we continue to navigate these crucial decisions and actions, you can view communications via our Community Resources Page <https://link.t.upwork.com/ls/click?upn=VqS90m2f8fx8n-2F1K6AZcGXdU-2Bum2rQJX…>, which we are updating frequently with new developments and FAQs. Our hearts and support go out to all those affected by this senseless aggression against Ukraine. We hope that a path to peace is ahead for Ukraine, and that we are able to bring our mission back to Russia and Belarus in the future.

off-topic: net-sec presentations (routing, DNS, and DoS)
by Amir Herzberg 08 Mar '22

08 Mar '22

Hi NANOGers, I've updated my DoS presentation - will begin teaching this topic tomorrow. It's in my website, together with the other network-security presentations I gave this term, mainly DNS and routing security; there are few more topics I'll cover this term, to be added soon. And, of course, there's also my `applied intro to crypto' and related presentations. Anybody interested and/or willing to provide constructive feedback is always welcome - and feedback (even less constructive :) ) is highly appreciated. However, please send me directly, this is off-topic enough and nanog isn't the forum to discuss. Unless there's something you really think of interest to the entire community, of course. Peace (hopefully, in Ukraine too), Amir -- Amir Herzberg Comcast professor of Security Innovations, Computer Science and Engineering, University of Connecticut Homepage: https://sites.google.com/site/amirherzberg/home `Applied Introduction to Cryptography' textbook and lectures: https://sites.google.com/site/amirherzberg/applied-crypto-textbook <https://sites.google.com/site/amirherzberg/applied-crypto-textbook>
