Screen reading: Electromagnetic information leakage from the computer monitor

Introduction/purpose: The security of systems can be jeopardized by compromising emanations. This paper provides an overview computer screen attacks. New technologies used to exfiltrate sensitive data from screens. Emission is the prevention electromagnetic signal attacks that are conducted or radiated. Methods: examines impact a side-channel attack intercepts compromised information screen. leakage also explained. Software-defined radios described explain malicious on monitors. Results: source determines nature they carry. most well-known issue associated with revealing emissions possibility intercepting visual displayed Conclusion: Visual monitors could intercepted software-defined radio which digitize desired frequency spectrum directly antenna, present it digital processor, and output application for data.
