2019/07/16:Several major Internet outages affected millions of users around the world during the month of June. A massive Google Cloud outage took outservice for most on the U.S. east coast, affecting third-party siteslike Discord, Snap, Vimeo and several of Google's own services.
Cloudflare suffered 2 outages, affecting Amazon, Linode and other
major companies reliant on Cloudflare's infrastructure. Also Facebook,
Twitter and Apple suffered from an outage leading to restricted user
This made evident, that Internet providers need to have better routing
filters. A secure Internet Architecture like SCION could prevent such
Internet-related outages. Its path-aware networking ensures that
packets arrive at the targeted destination, by enabling circumvention
of unavailable areas. Read the full article here.
2019/06/21:A research group at the University of Tennessee under Prof. Max Schuchard has devised a new form of DDoS attack, which they call the Maestro attack.
In their attack, the BGP protocol is exploited to focus botnet attack traffic onto a target link in the Internet, creating congestion on the link. The Maestro attack further strengthens the Crossfire attack, which is highly effective to conduct DDoS on today's Internet.
According to the researchers, although upgrades such as peer locking could help to prevent this specific attack, replacing BGP with an entirely new, next-generation system (e.g., SCION) would be the most effective solution.
2019/06/15:Security continues to be an important topic in today's Internet. With the Border Gateway Protocol (BGP) as its weakest link, many loopholes are exploited for attacks (e.g. prefix hijacking), calling for a secure Internet architecture.
An alternative to BGP is the SCION protocol which has a high level of security and can be verified by network operators, so that attacks can be prevented. Trust can be restored and hijacking completely avoided due to the fact that sender and receiver can define which path a packet takes (path-aware networking). Cryptographic verification of paths is also interesting for the financial sector, as described by an article published by NZZ (in German)
2019/06/07:The SCION secure Internet architecture could have prevented the outage on Thursday last week, when for two hours, a large chunk of European mobile traffic was rerouted through China.
The incident happened, because of a BGP route leak. The Boarder Gateway Protocol (BGP), that is used to reroute traffic at the ISP level, has been known to be problematic and BGP route leaks happen on a daily basis (https://bgpstream.com). This time however, instead of ignoring the erroneous BGP announcement, China Telecom re-announced Safe Host's information, resulting in a rerouting of European mobile networks trough China Telecom's network.
SCION makes the Internet more secure through path-aware networking and preventing BGP route leaks and prefix hijacking attacks. Read the full article here.
2019/04/25:The R&D team of SIDN (the registry for .nl) recently launched 2STiC, a joint research program to develop and experiment with mechanisms to increase the security, stability, and transparency of internet communications.
