White Noise
We tested a preproduction version of the code, and the TeleVPN Call Shield functioned as advertised, securing calls between our labs and an ETM-equipped SecureLogix development site in Texas. The product lets a call connect and pass standard signaling information. The bearer/media portion of the call is encrypted in real time with a maximum 80-ms latency.
The ETM let us repeatedly sync up and conduct encrypted calls without a hitch via a 64-Kbps channel for voice, fax and modem calls. For testing purposes, we used a Telecommunications Techniques T-Berd 107A
(a handheld tool for installing and monitoring T-carrier service) to listen in on our PRI channel by channel. We were able to eavesdrop on speech, fax tones and modem energy during unencrypted communications. During encrypted calls, all we got was an earful of hissing white noise from the scrambled signal.
Security keys are wrapped using 3DES and a chip-specific Key Encrypting Key programmed during chip production that cannot be retrieved from the crypto processor. There is no practical way to hack the system; you'd need physical access to the encryption chip.
To realize the benefits of cloud-native software, an application must actually be cloud-native—designed to run in the cloud, interacting with disaggregated cloud services, fully manageable as code—to deliver the expected benefits.
By combining resources and expertise, the AI-Enabled ICT Workforce Consortium will offer a blueprint for how industries can adapt to an AI-dominated future.
IT leaders should heed the guidance of cybersecurity insurance providers who think businesses should prioritize security education, incident preparedness, regular internal audits, and ongoing vulnerability scanning and patching.
