Critical infrastructures are complex operating environments that often require special protection and security. A successful security strategy design should adhere to the principles of durability, integrity, and regularity. In the European Union, there is a strong interest in the security of critical infrastructures, especially those with interdependence. Given the fact that critical infrastructures play an essential role in a country's economy, it makes them even more vulnerable. The main aim of this article is to analyze the critical infrastructures' cyber security policy. The creation of a security strategy requires identification of the needs for equipment, mode of operation, and required security level. It has to establish rules for precise operation and handling of situations. The article tackles the issues of security strategy for critical infrastructures to protect sensitive areas and sectors. In addition, a cybersecurity policy as a countermeasure is discussed.

Smart phone surveillance is a sensitive issue, so topical and important, which is about everyday life of all of us, I am talking about the smart phones, small smart phones, these small but powerful computers that everybody use them every day by doing more internet browsing rather than doing calls. The questions that arise about the security of smart phones are many, for example: may someone watch us? may the government hear what we saying and what messages we send? may they know our location? How much important meta-data is and to what extent it can reveal important information about the subscriber’s identity and how it relates to privacy and personal data. Finally, it is worth mentioning the participation of mobile phone providers in various government monitoring projects of the citizens either with targeted software which is not detectable, or with the direct access to the Servers of the providers for copying sensitive information without of course the consent of the subscribers. Such projects are the Carnivore, Prism, and other projects, and the countries involved in information exchange programs are behind lists identified as 5 Eyes, 9 Eyes, and 14 Eyes.

Industrial control systems (ICS) are critical, as in these systems, cyber threats have the potential to affect, disorganize, change their mode of operation, act as an information extraction vehicle, and ultimately turn against itself. Creating risks to the system itself, infrastructure, downtime, leakage of sensitive data, and even loss of human life. Industrial control systems (ICS) are vital to the operation of all the modern automated infrastructure in the western world, such as power plant and power stations. Industrial control systems (ICS) differ from the traditional information systems and infrastructures of organizations and companies, a standard cyber security strategy cannot be implemented but part of it adapting to the real facts and needs of each country, legislation and infrastructure
