by Mueller Urs SBB CFF FFS 14 Jul '23

14 Jul '23

Hello Curious about the «best practice» you use for IPv6 gateways in server config / datacenter. Votes for static gateway settings on servers? Or do you use IPv6 nd/ra? Or perhaps DHCPv6?

Sicherheit von SS7 - mit Schweiz-Bezug

(Resend von der richtigen Absender-Adresse) https://www.haaretz.com/israel-news/security-aviation/2023-05-10/ty-article… The Secretive Swiss Dealer Enabling Israeli Spy Firms (…) It leads from the Americas to Africa to South-East Asia, but also to Basel, a mediaeval town on the banks of the Rhine and the unassuming home of Andreas Fink, a Swiss telecom expert whose unusual skills have placed him at the centre of this industry. (…) reveal how Fink's systems have served as a conduit for probing and attacking phone networks across the globe (…) When contacted by this investigation, Fink admitted to working with companies and “legally entitled government agencies” as a provider of surveillance services. (…) Fink's request to Robert was for "SS7 access" and "a bunch of global titles". In other words, he wanted a list of phone numbers, belonging to Robert's phone company, which could be used to send queries to other networks in other countries.

Re: swinog Digest, Vol 219, Issue 11

Hmm, instead of securing their networks and pushing for better security standards they'll cut access to one fish. Is that an ideal strategy? Some other bigger meaner fish will still use those vulnerabilities. I was wondering if the GSMA is or should regularly perform security audits. https://www.gsma.com/security/gsma-mobile-security-research-acknowledgement… Or perhaps award publicly visible badges of honor to those mobile networks that are not vulnerable to similar attacks. I mean how many companies do we know? that publicly stated: Hello our mobile users btw. we fixed those vulnerabilities in our network! You should now be better protected. I never got any such information from any of my providers. Did you?
