RPKI ROA

Resource Public Key Infrastructure Route Origin Authorization is a mechanism within the RPKI framework that allows IP address holders to cryptographically authorize specific ASes to originate their prefixes in BGP announcements.

Security issues

Route Leaks are the propagation of routing announcements beyond their intended scope.

Route leaks

Accepted Route Leak is a route accepted into your routing table and includes a subpath with a route leak.

Accepted leaks

BGP Hijacking is an illegitimate prefix announcement by a malicious or misconfigured Autonomous System (AS).

Hijacks

Bogons are an announcement of prefixes or using ASNs (Autonomous System Numbers) that should not occur in routing tables, such as private networks or reserved ASNs.

Routing loops are network vulnerabilities when a packet is routed in a circle until its time to live exceeds.

Vulnerable Ports show open TCP ports of the network protocols, that are often used by network devices (especially border routers). If these ports are open to everyone, it can be a serious vulnerability.

DDoS amplifiers are network devices or services that can be exploited by attackers to significantly amplify the volume of a Distributed Denial of Service (DDoS) attack. These amplifiers are not inherently malicious but can be misused due to certain characteristics they possess.
