Abstract
According to an example aspect of the present invention, there is provided an apparatus comprising memory configured to store information characterizing at least one run-time behavioural pattern, at least one processing core configured to perform a behavioural determination based at least partly on the stored information, concerning a network node, and to verify, as a response to a result of the behavioural determination, whether the network node is comprised on a list of valid network nodes.
Claims26
An apparatus comprising:
- memory configured to store information characterizing at least one run-time behavioural pattern;
- and
- at least one processing core configured to:
- perform a behavioural determination based at least partly on the stored information, concerning a network node, and
- verify, as a response to a result of the behavioural determination, whether the network node is comprised on a list of valid network nodes, wherein:
- the network node is a virtualized network function or component of a virtualized network function that comprises a software implementation of a logical network node of a communication network;
- and
- the run-time behavioural pattern comprises at least one of the following patterns:
- an increase in CPU load combined with a decrease in capability of the network node;
- an increase in memory usage with no concurrent increase in communications throughput;
- an increase in outgoing traffic from the network node with no corresponding increase in ingoing traffic;
- and
- the network node is instantiated and active without being comprised in the list;
- and
- determine, based on the behavioural determination, whether the network node is a legal but hidden node or a spurious node.
