When you look at the most damaging network security invasions over the last year, you see a recurring pattern: leaked government cyber tools being repurposed by cybercriminals. The compromised NSA toolset leaked by Shadow Brokers was devastating in many respects. These were highly targeted tools that many nation states wish they had the operational capacity to deploy.
As intranet networks grow and evolve over time, often duplicate, or even multiple, paths are created to reach a destination. As these paths evolve and get more complex, they can result in failed links. Interior Gateway Protocols provide fast re-routing around these failed links using link-state algorithms, such as Open Shortest Path First (OSPF) and Intermediate System to Intermediate System (IS-IS).
