Multi-Path TCP: revolutionizing connectivity, one path at a time

CloudFaire

The Internet is designed to provide multiple paths between two endpoints. Attempts to exploit multi-path opportunities are almost as old as the Internet, culminating in RFCs documenting some of the challenges. As a result, Internet devices usually use a single path and let the routers handle the path selection.

Post-quantum readiness for TLS at Meta

Engineering at Meta

Today, the internet (like most digital infrastructure in general) relies heavily on the security offered by public-key cryptosystems such as RSA, Diffie-Hellman (DH), and elliptic curve cryptography (ECC). But the advent of quantum computers has raised real questions about the long-term privacy of data exchanged over the internet.

BGP Anycast Best Practices & Configurations

Noction

Anycast is tightly coupled with the BGP protocol, which ensures that the anycast route is advertised among autonomous systems (ASes) on the Internet. Packets to the anycast IP are routed through the shortest path to the server, reducing latency and improving service resiliency.

Where Web-Environment-Integrity came from

SysAdmin1138 Explains

In a company context, you can reasonably expect the company to own both the server and the machine employees are accessing internal resources from. Again, in a corporate context where the company reasonably owns both the client and server sides of the conversation. What does Web-Environment-Integrity allow server operators to do?

For example, look at the RFCs that describe the Internet. In that scenario, the client knows more about the structure of the server, but has less valuable information. Without it, the message is meaningless. The protocol might be implicit, but typically, the more users a protocol has, the more it needs to be formally described.

AWS Route 53 BGP Hijack: What Kentik Saw

Kentik

In simple terms, Border Gateway Protocol (BGP) is the protocol that routes traffic on the Internet. Each BGP speaking organization is assigned an Autonomous System Number (ASN) that identifies them on the Internet. During a BGP route hijack, an attacker advertises IP prefixes from an ASN that is not the normal originator.
