What is Telecommunications?

Understanding Telecommunications

Electronic systems used in the transmission or reception of information between two or more locations. Electronic systems may include voice video data or other information transmitted over physical media or wireless technologies. Telecommunications encompasses the technology infrastructure and systems that enable the transmission of voice data and other information between locations using various transmission media and protocols. Security for telecommunications is essential as these systems often carry sensitive information across potentially vulnerable channels. Telecommunications security is addressed in standards like NIST SP 800-53 SC controls ISO 27001 and various regulatory frameworks. Organizations secure telecommunications through encryption secure protocols network segmentation monitoring protected transmission media and redundancy. For example a financial institution might secure its telecommunications infrastructure by encrypting all voice and data transmissions using dedicated secure circuits for sensitive communications implementing strict access controls to telecommunications equipment monitoring for anomalous traffic and maintaining redundant communication paths to ensure availability.
