  • 7 Layers: MWC Barcelona 2023 Review

    7 Layers: MWC Barcelona 2023 Review
    Mar 8 2023
    Industry trade group GSMA stated that more than 88,000 people attended its recent MWC Barcelona 2023 event, a number that might be hard to verify but seems legitimate considering the masses of people spread throughout the multiple halls of Barcelona’s cavernous Gran Via. While attendance might not have matched the 109,000 people GSMA said had attended the last pre-Covid event in 2019, many in attendance were still amazed by the strong turnout for the mobile telecommunication industry’s largest annual event. On this week’s SDxCentral 7 Layers podcast, I am joined by Reporter Julia King to take a look back at the MWC Barcelona 2023 event, highlighting some of the bigger news and trends to emerge from the show. This includes: • The network API push highlighted by GSMA’s Open Gateway initiative that has so far attracted nearly two-dozen operators and vendors attempting to squeeze more revenue from 5G networks. • The differing dynamics between vendor heavyweights Ericsson, Huawei, and Nokia. Ericsson’s event splash was somewhat subdued due to ongoing operational challenges; Huawei looked to counter ongoing geopolitical struggles with sheer mass; and Nokia deconstructed its logo to emphasis its operating momentum. • There was considerable open radio access network (RAN) news from the event, especially from European-based operators that have been aggressively trialing different open RAN solutions and have staked out deployment benchmarks. • And what would a telecom focused event be without looking toward the future. In this case, it was expected benefits from soon-to-be-available 5G-Advanced specifications and further-down-the-road 6G technology. We are still at least a year away from the former, and at least five years away from the latter, but what fun is a trade show if you can’t dream a little. We hope you enjoy this audio look back at the MWC Barcelona 2023 event, and make sure to check out all of our coverage of the show on our dedicated event page. Learn more about your ad choices.

  • 7 Layers: Open RAN Security Stance a Sensitive Situation

    7 Layers: Open RAN Security Stance a Sensitive Situation
    Mar 1 2023
    The open radio access network (RAN) market recently gained significant U.S. government support when Federal Communications Commission (FCC) Chairwoman Jessica Rosenworcel touted open RAN as a way for operators to circumvent network equipment from China-based vendors like Huawei and ZTE. Specifically, Rosenworcel noted the ability for open RAN technology to provide operators with greater access to more secure networking equipment. “In the long run, these systems can help diversify the technology in our networks and grow the market for more secure 5G equipment,” she stated during a speech at a Center for Strategic and International Studies event earlier this year. The U.S. has earmarked billions of dollars to be used to help rip-and-replace existing network infrastructure from China-based vendors, including RAN equipment. The FCC had previously reported America’s wireless network infrastructure included at least 24,000 pieces of Huawei or ZTE equipment spanning about 8,400 locations. Most of this work toward open RAN has been under the guidance of the O-RAN Alliance, which is an industry trade group working on technical specifications that foster greater adoption of open RAN equipment. However, that organization has been questioned for its inclusion of some members linked to organizations included on the U.S. Entity List that tracks organizations and individuals considered to support “activities contrary to U.S. national security and/or foreign policy interests.” This issue at one point resulted in Nokia pausing activities with the O-RAN Alliance over concerns about Chinese members’ blacklisted status with the U.S. government. The O-RAN Alliance quickly adopted changes to its participation documents and procedures that brought Nokia back into the fold. John Strand, CEO of Strand Consult, stated that this connection should raise concerns over the security structure of open RAN equipment. “What I dislike is that open RAN has been marketed as an alternative to Chinese infrastructure,” Strand said. “Open RAN is just as Chinese as anything else. There’s 11 or 12 working committees in [O-RAN Alliance] and China Mobile is either the chair or the vice-chair of nine or 10 of them. China Mobile and 43 other Chinese companies on the U.S. Entity List are key stake holders in [O-RAN Alliance]. … That’s an issue.” On this episode of the SDxCentral 7 Layers podcast, Strand provides more insight into those potential concerns and areas where other security challenges could impact the adoption of open RAN architectures.

  • 7 Layers: Check Point VP Unpacks the Latest in Cloud Security, AI, ChatGPT

    7 Layers: Check Point VP Unpacks the Latest in Cloud Security, AI, ChatGPT
    Feb 22 2023
    In this episode of the 7 Layers podcast, TJ Gonen, VP of Cloud Security at Check Point sat down with SDxCentral Editor Nancy Liu to delve into the ever-changing world of cloud security – specifically emerging trends in the evolution of the cloud threat landscape. Furthermore, we will explore how advanced artificial intelligence (AI) and machine learning (ML) technologies, such as ChatGPT, are being utilized to enhance cloud security, and discuss the most promising AI and ML-based cloud security solutions. Check Point Research recently reported a 48% year-over-year increase in cloud-based cyberattacks for 2022, as organizations increasingly move operations to the cloud. “There are just way more cloud assets, so it's very natural for more attacks to happen on such a large estate,” Gonen told SDxCentral. “Another thing that's happening more and more, it's already a reality … is that more critical assets are moving to the cloud.” “That speed of change and scale of cloud is the number one reason for this increase in cybersecurity attacks,” he added. “So, operationalizing cloud security at speed and scale and keeping up is going to continue to be the biggest challenge.” AI and ML technologies can help address this issue as “[what] they are actually very good at is to move fast, is to automate stuff.” The Check Point Research team recently published several studies into OpenAI’s ChatGPT and Codex. “[What] Codex and ChatGPT show to all of us is what AI can do now,” Gonen said. “It just showed what impact it can have on almost everything we do in life, not just the technology nerds.” He noted Check Point has been using AI across the board for four years. “When you connect the security solution, you might find yourself with thousands of alerts, and sometimes thousands of alerts is a bigger problem than no alerts,” Gonen said. “One of the ways that we're using, for example, machine learning and AI, is to take these alerts and instead of just throwing them at the user, we actually use machine learning and AI to prioritize and talk about or focus only on the risks that matter. ” He also expects AI and ML technologies to replace some of the security layers that today are driven by humans. “For example, I think that we are maybe a year away from replacing, what's called in the security world, the tier-one analyst — the people who take alerts from a bunch of places and sit in a SOC and try to correlate them to understand what happens on the first tier.” “That's perfect because you can focus more on the higher-skilled individuals,” Gonen added.
