Explanation of terms
Genera
The term “electromagnetic pulse” (EMP) has been used in the media in recent years to describe many different types of electromagnetic threats to electronic systems.
However, it is necessary to distinguish between the types of electromagnetic threat, namely high altitude electromagnetic pulse (HEMP) and intentional electromagnetic interference. (IEMI)
HEMP is generated by a nuclear detonation in space, but the intense electromagnetic fields generated in space reach the Earth’s surface. In the case of non-nuclear EMP, there are many subcategories of terms that describe this electromagnetic threat. In general, they are intense electromagnetic fields generated by a repeatable high-power generator (without explosives) and directed at a target via an antenna.
The term “High Power Electromagnetic (HPEM)” has been used for many years and generally describes a range of transient EM environments where the peak electric and magnetic fields can be very high. Typical environments include electromagnetic fields emanating from a nearby lightning strike, electromagnetic fields near an electrostatic discharge, electromagnetic fields generated in substations by switching operations and arcing, and electromagnetic fields generated by radar systems. These are natural and accidental electromagnetic threats.
Recently, two new terms have emerged in the field of EMC: electromagnetic terrorism and intentional electromagnetic interference (IEMI). The definition of “IEMI” is therefore the intentional, malicious generation of electromagnetic energy that introduces noise or signals into electrical and electronic systems, thereby disrupting or damaging these systems for terrorist or criminal purposes.
The motives of the attackers may be different, but the consequences for civil society could be the same, as the greatest threat is clearly to civilian infrastructure. The shutdown of control electronics associated with the power grid, the telecommunications network, or other parts of the critical infrastructure could have far-reaching and very serious consequences. Our concern is how to protect our commercial infrastructure from these new mobile threats.
Cyber attacks
A cyber attack is any type of attack directed against information systems, infrastructures, computer networks or computing devices. The damage caused by cyber attacks runs into the billions. According to a study by the digital association Bitkom, this amounts to 223 billion euros per year. In Germany, many companies are affected, especially small and medium-sized enterprises. In 2020 and 2021, almost nine out of ten companies were affected by data theft, espionage or sabotage. According to the study, almost the entire economy is affected by cyber attacks. A common form of cyber attack is eavesdropping. This is a process of intercepting network traffic that allows the attacker to gain access to passwords, credit card numbers and other confidential information.
The spy comes from the air
Cyber criminals are now using drones for their attacks.
While walls and fences with video technology and corresponding doors used to provide reliable outdoor security, these measures have become completely ineffective against the danger from above.
Unmanned flying objects approach the premises, barely visible to the naked eye. In this way, they come close to the company’s internal radio network.
This includes WLAN, wireless connections to peripheral devices such as keyboards, IoT systems that communicate via radio and, of course, wireless systems for building control.
Drones can then, for example, record or manipulate the communication between industrial systems and the Manufacturing Execution System (MES). They can film screens through the office window with a high-resolution camera or record the entry of PIN codes into access systems.
What can companies do against the threat from the air?
Acoustic, optical and electronic methods can be used to detect and identify drones. However, cameras and acoustic sensors only cover relatively short distances, so the time between entering airspace and detecting the flying object is very short to take appropriate countermeasures.
Detection is one aspect of drone defence, interception another. Laser technology or electromagnetic pulses can also be used to directly target drones. The measures vary from country to country. Generally, these measures are reserved for the police and military. The options for defence against drones are therefore limited.
Consequently, it is important for companies to create an appropriate risk awareness and to consider the danger of drones in their security strategy.
Thanks to the products we present, it is possible to protect yourself. If you provide your windows with our window shielding film 75-183.
This film introduces an architectural shielding solution that is becoming increasingly important not only in private buildings to protect against electromagnetic radiation, but also for government organisations, businesses, architects and builders looking for ways to design safer buildings.
Application
The film can be easily adapted to existing designs or integrated into laminated glazing to reduce the intensity of radiation in living and working spaces.
An electrically conductive and optically transparent EMI shield that reduces the exposure of building occupants to electromagnetic radiation from nearby microwave and radio frequency sources. These sources of electrical and magnetic energy include cellular towers (4G, 5G, 6G) and also many other electronic devices, including WLAN.
Our shielding paint in combination with our shielding fleece also offers perfect protection against electrosmog and eavesdropping.
