## Abstract

A method for adapting the security settings of a communication station (12) depending on a security relevant event is disclosed, wherein the communication station (12) comprises a mobile terminal (16) with an identification module (18). In a first step, the security relevant event occurring in said communication station and/or said mobile terminal (16) is identified in an event handler (26, 261, 262, 27) and stored in an event registry (28). In a second step, a security registry (30) in the identification module (18) is updated according to the identified event. In a third step, the security level of the communication station (12) and/or the mobile terminal (16) is adapted according to the security registry (30) of the identification module (18). The invention also relates to a communication station (12) and to an identification module (18).

## Claims

### Claim 1

A communications station associated with an identification module that stores identification information used in a communications network, the identification module comprising at least one security registry for adapting and enforcing a security level of the communications station, wherein:
security settings set in at least the one security registry are used to apply security mechanisms against one or more applications executed by or run in the communications station, with respect to allowing or limiting interactions with applications or information in the identification module; and
the security settings are updated in response to a change in hardware configuration of the communications station.
