Objectives:
The article aims to provide an overview of the functioning of the Polish information security system and its vulnerability to intelligence threats from foreign secret services. The author identified and discussed what state information security is in the context of protecting strategic information resources from unauthorised disclosure. Furthermore, another objective of the work was to indicate the scope of criminal liability for the unlawful disclosure of information through participation in intelligence activities.

Methods:
The work analyses the acts of Polish law regulating information security issues and describes the system of state institutions responsible for safeguarding information security. The thesis also uses the methods of exegesis of legal texts and induction and deduction.

Results:
The considerations presented show that maintaining an appropriate level of information security in the Republic of Poland is very important in the context of growing intelligence threats from foreign countries. It should be noted here that under the current Criminal Code, the disclosure of information to foreign intelligence services may result in increasingly severe penalties for certain behaviours identified as participation in or activity on behalf of foreign intelligence.

Conclusions:
An analysis of the Polish information security system and the offence defined in Article 130 of the Criminal Code has shown that the scale of sanctions for unlawful conduct related to the information security system and exhausting the provisions of the aforementioned legal norm is multidimensional from the point of view of the Republic of Poland's information security and is treated seriously by the Polish legal system.
