Methods, nodes and operator network for enabling management of an attack towards an application

Abstract

Methods, a user data node (), a policy node (), an application node () and an operator network () for enabling management of an attack towards an application () hosted by the application node () are disclosed. The policy node () receives () attack information and an identifier of the application () to which the attack information applies. The attack information relates to the management of the attack and the attack information comprises a type of attack, a set of detection conditions relating to detection of attacks of the type of attack, and a mitigation action to be invoked when at least one detection condition of the set of detection conditions is fulfilled. In this manner, degeneration of the application () caused by the attacks of the type of attack is mitigatable. The policy node () generates () at least one rule based on the attack information. Moreover, the operator network () transfers (), from the policy node to the user data node (), said at least one rule. The user data node () detects (), in traffic towards the application (), the attack while utilizing said at least one rule. Corresponding computer programs and computer program carriers are also disclosed.
