The internet is being used extensively by businesses. To connect with different networks organizations use BGP for routing web traffic and communicating with different networks. But many times, businesses also face issues with BGP, and we will address such issues here, and how they can be countered (Networks against BGP route).
How to find your local and external address?
Firstly, what is BGP?
BGP stands for Border Gateway Protocol. It is the routing protocol used to find communication paths to connect with different networks. However, the BGP security is nil and that is why BGP is prone to security vulnerabilities that criminal individuals and governments can use to exploit and misuse sensitive information (Networks against BGP route).
What is BGP used for?
BGP is a standard gateway protocol that allows routing of information among ASes (Autonomous Systems) on the internet.
There are two types of BGP:
1. The standard BGP which is an Exterior Gateway Protocol between different Ases.
2. The iBGP is an Interior Border Gateway Protocol where routing happens within an autonomous system.

Problems with BGP?
One major problem many corporations are facing is BGP hijacks, BGP manipulation, BGP denial of service (DoS), and BGP leaks. A device is used to maliciously reroute the internet traffic is malicious to another router, and the actual information does not reach the original destination. When BGP is hacked or leaked or manipulated, the internet traffic is assessed by someone else who could then launch a series of spam campaigns, IP blacklist bypass, etc.
How does BGP routing work?
BGP is the internet protocol that allows Autonomous systems or independently operated networks to inform each other about their reachability and paths. In simple language, BGP is the language that routers use to communicate. Every time a BGP router advertises its reachability or IP prefix to its neighbor network, the new IP prefix is compared against the router’s stored information. If this new advertisement or IP prefix shows a better path and reachability to a certain network, the new IP prefix information is updated in the local router and this information is shared with all immediate network neighbors. This way new networks or autonomous systems emerge or disappear every day. This kind of protocol is based entirely on trust among the networks and if the new advertisement or IP prefixes are shared with other routers, there is no verification on the origin or if the router is genuine or malicious. The advertisements or IP prefixes are usually unencrypted and could reach any routers around the globe.

How to protect networks against BGP route attacks?
The Internet Society launched the Mutually Agreed Norms for Routing Security (MANRS) initiative in 2014. Under this initiative networks can follow the following four methods to secure their BGP route:
Global validation – Documentation and validation of routing policies are publicly shared by the service provider.
Filtering – The documentation and filtering of routing policy will ensure that valid routes are announced.
Anti-Spoofing – Anti-spoofing filtering is used to only allow entry in the networks of the correct source IPs.
Coordination – There must be easy accessibility of Service providers’ up to date contact information.
Hence, when you purchase IP blocks or IP addresses for your organization, overlooking the BGP routing attacks could cost your networks a lot.
