President Joe Biden reconfigured the leadership and membership of his National Security Telecommunications Advisory Committee (NSTAC), and said he plans to add more than a dozen new members to the public-private partnership.

NSTAC runs under the government’s Cybersecurity and Infrastructure Security Agency (CISA). It’s tasked with providing the government with advice for securing and maintaining the operational integrity of the nation’s telecommunications networks.

President Biden late last week stated Microsoft executive Scott Charney would take over as NSTAC committee chair, replacing previous chair and former AT&T executive John Donovan, who had served in that role for nearly four years. Charney, who is VP of security policy at Microsoft, previously served as vice chair of the committee under Donovan.

The President also named 13 new members to NSTAC’s committee, including:

• Jeffrey Storey, senior advisor to Lumen’s board and its CEO
• Johnathon Caldwell, VP and GM of Lockheed Martin’s military space operations
• Mark Dankberg, chairman, CEO, and co-founder of satellite communications provider Viasat
• Noopur Davis, corporate EVP and chief information security and product privacy officer at Comcast
• Barbara Humpton, president and CEO at Siemens
• Kimberly Keever, chief information security officer (CISO) at Cox Communications
• Kyle Malady, president of global networks and technology at Verizon
• Kevin Mandia, CEO of Google Cloud’s Mandiant division
• Maria Martinez, COO at Cisco
• Jeff McElfresh, COO at AT&T
• Bryan Palma, CEO at Trellix
• Neville Ray, president of technology at T-Mobile US
• Corey Thomas, CEO at Rapid7

Previous members included Intel CEO Pat Gelsinger, Amazon Chief Security Officer Stephen Schmidt, Qualcomm Chairman Mark McLaughlin, and Broadcom President and CEO Hock Tan.

The update comes as the federal government continues to work through the hardening of the country’s telecommunications and information infrastructure.

Some of that works includes the recent push of the Federal Communications Commission (FCC) adopting rules to ban the domestic use of telecommunications and network gear from Huawei, ZTE, and a handful of China-based telecommunication vendors deemed to pose a security threat to the nation’s communications network.

More recently, FCC Chairwoman Jessica Rosenworcel touted the use of open radio access network (RAN) standards as a way for U.S. operators to circumvent network equipment from Chinese vendors.

“This effort is now underway, though completion by carriers depends, in part, on further funds from Congress for the reimbursement program – and that is key,” Rosenworcel said during a speech at the recent Center for Strategic and International Studies event. “When we set up this reimbursement program, we also made clear this was an opportunity for carriers to transition to open radio access network systems. In the long run, these systems can help diversify the technology in our networks and grow the market for more secure 5G equipment.”
