“Security” In a Digital Interconnected World
This document discusses internet security and resilience. It argues that security is about managing acceptable risks rather than stopping all threats. An open, collaborative approach based on technical standards and cooperation across borders is needed. Voluntary initiatives like MANRS that define best practices for routing security and encourage networks to implement them can help address complex issues in a way that preserves internet values. Pervasive monitoring shifts rather than eliminates surveillance and technical solutions must balance security with privacy and innovation.

Editor's Notes
- #3 The open and global nature of the Internet, built on fundamental principles of open standards, voluntary collaboration, reusable building blocks, integrity, permission-free innovation and global reach, has enabled remarkable social and economic innovation in ways that we could never have imagined. At the same time, using the Internet is not without risk. Malicious actors also see opportunities to gain benefit through fraud, to thwart the activities of others, inflict harm or other damage, and to generally cause mayhem. It is important to appreciate that while malicious actors will exploit any opportunity, the Internet’s key characteristics are neither the origin nor the cause of the malicious activity.
- #4 The Internet is global because any endpoint connected to it can address any other endpoint. The integrity of the Internet means that information received at one endpoint is as what was intended by the sender, wherever the receiver connects to the Internet
- #8 Traditional approaches to security were principally concerned with external and internal threats, and the impact they may have on one’s own assets [in other words, threat-based and self-interested]. There is, however, a growing recognition that a security paradigm for the Internet ecosystem should be premised on protecting opportunities for economic and social prosperity, as opposed to a model that is based simply on preventing perceived harm.
- #9 It’s the Economy… Challenge the idea that “security” has to be a trade-off between that which you want to do and having an acceptable level of security. Reasonably understood risks
- #10 Like a human body that may suffer from viruses, but gets stronger and more resilient as a result, new technologies, solutions and collaborative efforts make the Internet more resilient to malicious activity.
- #11 The Internet, with its high degree of interconnection and dependencies, brings another dimension to the management of risks. Security and resilience of the Internet depends not only on how well risks to you and your assets are managed, but also, importantly, on the management of risks that you (by your action or inaction) present to the Internet ecosystem – the “outward” risks. Additionally, some risks need to be managed by more than one actor. This is the notion of collective and shared risk management – a notion that is well aligned with the “public interest” nature of the Internet. This latter aspect of risk management is not necessarily self-evident, especially since there is often no obviously identifiable immediate harm to the actors or their assets and, therefore, no direct business case that can be immediately associated with such effort. And, it also is human nature to seek outcomes that further our individual “self-interest”. However, such a narrow approach is counter-productive and, in the long-term, harmful to everyone’s interests – not only will it impact the security of the ecosystem, but it will also diminish the overall pool of social and economic potential that the Internet offers.

- #25 Prevent propagation of incorrect routing information Network operator defines a clear routing policy and implements a system that ensures correctness of their own announcements and announcements from their customers to adjacent networks with prefix and AS-path granularity. Network operator is able to communicate to their adjacent networks which announcements are correct. Network operator applies due diligence when checking the correctness of their customer’s announcements, specifically that the customer legitimately holds the ASN and the address space it announces. Prevent traffic with spoofed source IP address Network operator implements a system that enables source address validation for at least single-homed stub customer networks, their own end-users and infrastructure. Network operator implements anti-spoofing filtering to prevent packets with an incorrect source IP address from entering and leaving the network. Facilitate global operational communication and coordination between the network operators Network operators should maintain globally accessible up-to-date contact information. Facilitate validation of routing information on a global scale. Network operator has publicly documented routing policy, ASNs and prefixes that are intended to be advertised to external parties.
