Cisco IOS XR vulnerability lets attackers crash BGP on routers
Cisco has patched a denial of service (DoS) vulnerability that lets attackers crash the Border Gateway Protocol (BGP) process on IOS XR routers with a single BGP update message. IOS XR runs on the company’s carrier-grade, Network Convergence System (NCS), and Carrier Routing System (CRS) series of routers, such as the ASR 9000, NCS 5500, and 8000 series. This high-severity flaw (tracked as CVE-2025-20115) was found…

BGP Security Enhancements Guide & 7 Best Tools for 2025
Border Gateway Protocol (BGP) is the fundamental standard that enables communication between different Autonomous Systems (AS) on the internet. It is a path vector protocol used to exchange routing information between internet service providers (ISPs) and large enterprise networks. BGP has some inherent vulnerabilities that make it susceptible to attacks, such as route hijacking, route leaks, and other types of…

5 Best BGP Monitoring & Anomaly Detection Tools for 2025
Border Gateway Protocol (BGP) is the only routing methodology that operates on the Internet. It is central to the routing decision-making implemented by routers. Thus, it enables data to traverse networks across different Autonomous Systems (ASes). Given its foundational importance to internet traffic flow, BGP has unfortunately become a prime target for malicious actors. The nature of BGP’s design, which…

BGP Route Hijacking Prevention & 5 Best Tools for 2025
Border Gateway Protocol (BGP) is a critical component of the Internet’s routing infrastructure, enabling communication between various Autonomous Systems (ASes) and ensuring the reliable delivery of data across the Internet. However, its design has several vulnerabilities that make it susceptible to attacks. One of the most dangerous is BGP route hijacking. BGP route hijacking occurs when an AS maliciously advertises…
