FCC and CISA host roundtable on Alerting Security Oct 30 2023
by Sean Donelan 16 Oct '23

16 Oct '23

The Federal Communications Commission’s Public Safety and Homeland Security Bureau (PSHSB), together with the Cybersecurity and Infrastructure Security Agency (CISA)’s Emergency Communications Division, will host a public roundtable on the cybersecurity of the nation’s public alert and warning systems. The roundtable will start at 9:30 a.m. EDT on Monday, October 30, 2023. This event will focus on cybersecurity in alerting, risk management frameworks as well as the cost and benefits of implementing these in incident reporting for alerting. https://www.fcc.gov/document/fcc-and-cisa-host-alerting-security-roundtable…

In previous lives, I've regularly been on the receiving end of assorted audit requests from RIPE, some of which are to do with contact details in the DB (particularly when they find unreachable ones), and some of which are confirming that number resources are still in use by the organisation and for the purpose for which they were issued. I think the original complaint was that RIPE don't act (or less so than ARIN) to block or otherwise deal with people who are mining the DB for contacts, despite that being an incentive to put "real" data in the DB - not than that they don't push for accurate data in the DB. Thanks, Tim.

Since 2005 the number of IPv4 FIB entries per origin AS has increased fropm 8 to 12 in the past 20 years - or a 50% increase. Over ther same period the number of IPv6 prefix advertisements per origin AS has increased from 1.5 to 6, or a fourfold increase. If anything, the IPv6 story appears to me to be a far greater cause for concern, but you may have a different interpretation of this data.

ARIN whois contact abuse from ipv4depot aka Silicon Desert International Inc
by Eric Kuhnke 13 Oct '23

13 Oct '23

Is anyone else receiving spam from this organization? Based on the contents of the cold solicitations they are sending us, and the addresses being sent to, they have scraped ARIN WHOIS data for noc and abuse POC contact info and recent ipv4 block transfers. It's trivially easy to block their entire domain at the mail server level, of course...

No blocks at all. So they don’t use NAT? The internet is a peer-to-peer network. NAT breaks that. But I can’t reach IPv6 devices on the Internet from my IPv4 device without a transition box is no different to I can’t reach IPv4 devices on the Internet from my IPv4 device because PNAT *is* a transition device. It’s a bogus complaint and I’m calling it out. > scott -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: marka(a)isc.org

How about we educate each other to not assume you must deaggregate your prefix especially with IPv6? I see 'some' (it's highly relative) networks on IPv4, they 'believe' they have to advertise every single /24 they have. And when they start with IPv6, they replicate the same mindset with a tons of /48 . You can imagine what will happen of course. A better alternative IMHO is to take advantage to the large prefix range and advertise a sub-aggregate when necessary. But absolutely not each end-node or customer prefix. -- Willy Manga @ongolaboy https://ongola.blogspot.com/

constraining RPKI Trust Anchors
by Job Snijders 12 Oct '23

12 Oct '23

Dear all, Two weeks ago AFRINIC was placed under receivership by the Supreme Court of Mauritius. This event prompted me to rethink the RPKI trust model and associated risk surface. The RPKI technology was designed to be versatile and flexible to accommodate a myriad of real-world deployment scenarios including multiple trust anchors existing, inter-registry transfers, multiple transports, and permissionless innovation for signed objects, for example. All good and well ... but ofcouse there is a fine print. :-) Over the years various people have expressed astonishment about each RIR having issued so-called 'all-resources' (0.0.0.0/0 + ::/0) trust anchor certificates, but this aspect often is misunderstood: the risk is not necessarily in the listing of 'all-resources' itself, it is in the RIR being able to issue an 'all-resources' certificate in the first place. RPKI trust anchor operators indeed can voluntarily reduce the scope of subordinate Internet Number Resources, but just as easily increase the scope of their authority. In other words, a trust anchor cannot truly constrain itself. Upon reconsideration on how exactly RPKI hooks into the real world; I concluded trust anchors do not require unbounded trust in order to provide constructive services in the realm of BGP routing security. Some examples: ARIN does not support inter-RIR IPv6 transfers, so it would not make any sense to see a ROA subordinate to ARIN's trust anchor covering RIPE-managed IPv6 space. Conversely, it wouldn't make sense to observe a ROA covering ARIN-managed IPv6 space under APNIC's, LACNIC's, or RIPE's trust anchor - even if a cryptographically valid certificate path existed. Along these lines AFRINIC doesn't support inter-RIR transfers of any kind; and none of the RIRs have authority over private resources like 10.0.0.0/8 or AS 65535. It seems feasible to paint constraints around RPKI trust anchors in broad strokes. Over the last two weeks I've diligently worked with Theo Buehler to research RIR transfer policies, untangle the history of the IANA->RIR and RIR->RIR allocation spaghetti, design & implement a maintainable constraints mechanism for rpki-client(8), and publicly document the concept of applying operator-defined policy to derived trust arcs. Please take a moment to read https://www.ietf.org/archive/id/draft-snijders-constraining-rpki-trust-anch… Your feedback is appreciated. Kind regards, Job
