Threats related to the TOE operational environment expressed by enhanced generics.

Prefix, mnemonic	Description
Attacks against sensor network and transmission ability (TOE operational environment)
TEO.CommInterfer	Intruder [Sparam] interferes network communication by sending messages through different protocol layers (e.g., jamming, collisions, flooding), causing that the data [Dparam] are lost (usually inconspicuously for their owner or destination) or the node disappears (“has been stolen”).
TEO.RoutingMisuse	Intruder [Sparam] interferes routing by ignoring all or some messages or network communication.
TEO.Malware	Malicious software designed to infiltrate or damage a sensor node or sensor network.
TEO.BackdoorOpen	Using the wireless access point an intruder [Sparam] creates a backdoor for the network of an organization (corporation) from the sensor node side.
TEO.AttackPropagation	The possibility of attack propagation from a node to other nodes, gateways and external servers.
TEO.UncontrolledArea	Due to uncontrolled pervasiveness of a wireless sensors network, the node works in an uncontrolled network area accessible to potential intruders [Sparam].
Attacks causing safety problems
TEO.SafetyProblem	The manipulation (corrupting, replaying, blocking) by [Sparam] of the data [Dparam] sampled by sensors with the intention to hide or delay the detection of safety-critical faults in the safety-critical equipment to potentially induce hazards.
Attacks exploiting vulnerabilities related to insufficient administration
TEO.SecDataAdmin	Insufficient administration of the network and security related data [Dparam] of the sensor network by [Sparam].
