EMSEC, also known as emission security, is the investigation of a system’s susceptibility to unauthorized access due to electromagnetic emanations from hardware. This practice is commonly used in telecom systems, radio networks, cryptographic systems, and other communication facilities. It has become an essential component in protecting sensitive data for both government and company activities.
EMSEC includes the use of high-frequency screening systems for electromagnetic shielding. Our team has significant experience in architectural shielding against microwave and radio-frequency radiation, providing our clients with highly effective and affordable solutions regardless of the project’s size.
The US Department of Defense has developed standards to shield hardware and limit emanations to address concerns about emission security. Almost every piece of technology emits electromagnetic energy, which could result in data being released to unauthorized parties. However, systems that adhere to DoD specifications offer protection against illegal access. While EMSEC procedures are commonly used in military communications, the term TEMPEST is frequently used in civilian contexts to describe emission security efforts.
FAQs
What is EMSEC?
EMSEC, or emission security, is the investigation of a system’s vulnerability to unauthorized access due to electromagnetic emanations from hardware.
Why is EMSEC important?
As almost every piece of technology emits electromagnetic energy, it poses a risk of releasing sensitive data to unauthorized parties. EMSEC provides protection against illegal access and has become an essential component in safeguarding sensitive data for both government and company activities.
What is TEMPEST?
TEMPEST is a codename created by the US government and is frequently used to describe emission security efforts in civilian contexts.
Conclusion
EMSEC is an essential practice in safeguarding sensitive data for both government and company activities. It includes the use of high-frequency screening systems for electromagnetic shielding and adheres to DoD standards to provide protection against illegal access. As technology continues to advance, EMSEC remains a crucial component in maintaining data security.
