Background for this topic.
Telcos provide mobile, fixed-line, broadband, messaging, and data-transmission services. Their assets include radio access networks, fiber and transport links, core network functions, subscriber and billing systems, customer portals, and management platforms. They depend on power, data centers, timing, interconnection and roaming partners, and complex signaling between networks. Availability and integrity matter for ordinary connectivity and, where supported, emergency calling and other public-safety services.
Security concerns include unauthorized access to network-management systems, weaknesses in signaling such as SS7 or Diameter, compromised subscriber identities or SIM/eSIM processes, and vulnerabilities in virtualized or cloud-hosted network functions. These could enable message interception, fraud, location exposure, or service disruption, but are not inherent to every provider. Useful controls include strict separation of management access, strong authentication, signaling validation and monitoring, timely patching of network equipment and software, supplier assurance, and tested failover. Privacy programs must also protect subscriber data and communications metadata, while incident response should account for dependencies on interconnects and other operators.
Proposal pushes stricter infosec safeguards after Chinese state baddies expose vulns The head of America's Federal Communications Commission (FCC) wants to force telecoms operators to tighten network security in the wake of the Salt Typhoon revelations, and to submit an annual report detailing measures taken.…
Security chief talks to El Reg as Feds urge everyone to use encrypted chat interview While Chinese-government-backed spies maintained access to US telecommunications providers' networks for months – and in some cases still haven't been booted out – T-Mobile US thwarted successful attacks on its systems "within a single-digit number of days," according to the carrier's security boss Jeff Simon.…
Chinese state hackers, known as Salt Typhoon, have breached telecommunications companies in dozens of countries, President Biden's deputy national security adviser Anne Neuberger said today. [...]
The politics of cybersecurity are too important to be left to the politicians Opinion Here's a front-page headline you won't see these days: CHINA'S SPIES ARE TAPPING OUR PHONES. Not that they're not – they are – but, like the environment, there's so much cybersecurity horror in the media that, yes, of course they are. And?…
