The biggest disadvantages of BGP and possible risks Message acceptance and trust by individual BGP routers that communicate with each other during transmission is a default property of the BGP protocol. After receiving the message, an IP prefix will be installed and the given autonomous system will start announcing this prefix to other networks using BGP. The problem is that any autonomous system that has gained access to a BGP router can announce any prefix. The BGP protocol was created in times when the world network consisted of only a few autonomous systems with good mutual relations.
Therefore, no one even thought that they should verify the USA Phone Number List credibility or perhaps the source of the reported prefix. Fake IP prefixes can lead to DoS attacks . In addition, unintentional errors in the configuration are also common , which can cause not only the unavailability of one's own network, but can also negatively affect other networks or even a significant part of the Internet. How BGP works and why hijacking happens. Typical BGP abuse cases Prefix Hijacking – This is the process of intentionally or unintentionally taking control over a group of IP prefixes of another network.
This is achieved by changing the route that is used to transmit information. the more specific prefix always wins , and therefore to carry out prefix hijacking it is enough to announce to the BGP router a longer prefix than the prefix of the potential victim therefore it is the second prefix preferred and the second route is selected for transmission). There are also cases of partial hijacking of the prefix. In such a case, two autonomous systems announce the same IP prefix of the same length. Route manipulation.
