Title: Network security
Inventor: Gustavo Federico Petri
IPC: H04L41/085
Filed: 2020-08-25
Abstract: A network node coordinator system 110 in a network 150 comprising one or more network nodes 130 receives a global security policy 120 to be applied across the network and processes it to specialise the policy to produce an associated specific local policy 160 for each node which are transmitted to the nodes. Local policies may indicate a security policy for communications between one or more execution environments 180 on the nodes. The coordinator may register new execution environments that start execution on a node and in response provide a specialised local policy to be re-transmitted to the node. Traffic from the new execution environment may be blocked until registration. The coordinator may receive an updated global policy, after which it may update local policies to be distributed. The global policy may comprise rules to be applied to entities in the network having labels, the coordinator assigning the labels dynamically. The policies may indicate allowed traffic flows, and/or required security for communications. Also claimed is a network node comprising encapsulated execution environments and barrier circuitry restricting use of the interface based on a received local policy (fig. 2). Traffic from the execution environments is restricted to flowing via the barrier.
