  Analyzing the unintended security implications of AS-Path Prepending towards a more secure Internet routing ecosystem, Descrição: Coordinating how trac ingresses an Autonomous System (AS) has never been more crucial for network operators. Today, most ASes receive much more trac than they produce and are increasingly connected to other ASes and peering infrastructures. Among the techniques for Inbound Trac Engineering (ITE), ASPP is one of the most deployed as it has no operational requirements, is easy to use, and is one of the rst ITE solutions in routing manuals. By preliminarily analyzing BGP data from Route Views, RIPE RIS, and Isolario, we identied that more than 30% of the ASes use ASPP, with these prepending more than 25% of all IPv4 prexes at the origin today. Besides its advantages, ASPP has unintended implications for routing security. By making paths longer with ASPP, ASes amplify the risks of existing routing attacks (e.g., BGP prex hijackings) and the impacts of route leaks. For example, if an AS originates prepended routes, another AS can more easily originate a shorter route that will be partially able to attract the trac. Another possibility is for an AS to (partially) remove prepends that were added by another AS, also resulting in the possibility of trac attraction. ASes can remove prepends to attract trac to perform trac inspection or to earn more revenue by increasing the 95th-percentile of the trac of (some) of its customers. Also, ASes that originate their routes with ASPP are more likely to be impacted by route leaks if one of the non-prepended alternatives leaks. While RPKI would be able to prevent some prex hijackings, our preliminary investigation shows that less than half of the prepended prexes have ROAs. Also, for ROAs to work, other ASes must perform ROV, which is still under deployment on the Internet. We note that RPKI is neither capable of preventing attacks involving the removal of prepends nor reducing the impacts of route leaks or of prex hijacking attacks that manipulate the path instead of the origin. To identify the practicality of these unintended implications, as part of our ongoing research, we performed two active measurement campaigns using the PEERING testbed. In one, we spotted at least three ASes consistently removing the prepends of our prex announcements. While the number in this limited evaluation is not high, it indicates that ASes are tampering with prepended routes. In the second experiment, we analyzed how much the use of ASPP impacts the adoption of hijacked routes. We announced our prex from one of our PoPs and attempted to hijack this same prex from another PoP using a dierent ASN as the originator. We conrmed the expectation that ASPP increases the chances of success of prex hijackings: in all cases with three extra prepends, more than 90% of the BGP monitors from Route Views, RIPE RIS, and Isolario, adopted the hijacked route. By preliminarily analyzing the available BGP data, we identied many cases of ASes announcing prexes with prepending congurations that seem to achieve no goal other than increasing security risks. For example, more than 30,000 prexes are being advertised with the same number of prepends to all neighbors, resulting in no indication of which neighbor the AS prefers for the inbound trac. Other 8,000 prexes are announced with at least two prepend sizes, but with no visible route without prepending (e.g., 2 and 4 prepends only). If instead, the AS announces a non-prepend route, and another with two prepends, it would achieve the same goal while reducing security risks. This project aims to analyze the deployment of ASPP on the Internet, especially in the LACNIC region, oering to network operators a better understanding of ASPP benets and its unintended implications and contributing to improve the security of the Inter. , Situação: Em andamento; Natureza: Pesquisa. , Integrantes: Pedro de Botelho Marcos - Coordenador / Marinho Barcellos - Integrante / DAINOTTI, ALBERTO - Integrante / FELDMANN, ANJA - Integrante., Financiador(es): Registro de Direcciones de Internet de América Latina y Caribe - Cooperação.
