As the first truly cloud-native core network, 5G Core (5GC) will play a pivotal role in the transformation of the mobile ecosystem to enable multi-access edge computing (MEC) and low-latency, high-value services it makes possible. Operators will be able to handle vastly more traffic at higher bandwidth, deliver new types of applications for enterprise, vertical, and consumer markets, reduce operating costs, and meet the high expectations of the modern digital economy.

“But isn’t OpenStack dead?”, asked my engineering manager when we discussed the industry trends and roadmap deliverables.

Allowing important systems to auto-update and connect to the internet at all is a large problem. The customer has to think long and hard about the trust that they put into any software vendor. Implicit trust is a mistake in today’s hyperconnected world, and this incident shows a need to employ an expanded shared responsibility mindset to verify trust.

DDoS attacks impair availability of network and services, crowding out legitimate traffic with spurious and malicious traffic or slowing down response times. Large volumetric DDoS attacks as large as 2.3 Tbps can cause entire service provider networks to crash, denying service to large numbers of consumers and businesses. The more common, smaller and targeted DDoS attacks (<5 Gbps) are large enough to put a small hospital network out of service or provide a distraction for planting ransomware. Most of these smaller attacks, 75 percent, according to Neustar, are undetected. DDoS attacks are increasingly sophisticated and multi-vector, often building slowly to escape easy detection. For service providers, handling terabits of traffic every second, these smaller, slower attacks are especially difficult to detect and mitigate.

According to the Department of Health and Human Services there has been an almost 50 percent increase in healthcare cybersecurity data breaches between February and May 2020 compared to 2019. This is thought be a result of the COVID-19 pandemic distracting the industry due to the sweeping changes required, putting extra pressure on already inadequate healthcare cybersecurity measures. According to Natali Tshuva, CEO and cofounder of Sternum, an IoT cybersecurity company, “Hackers know that the healthcare industry is a mess right now in terms of cybersecurity and this gives them even more motivation to create more and more attacks.”

The industry trends accelerate public cloud adoption and many organizations nowadays operate application delivery services in multi-cloud or hybrid-cloud deployments using on-premises data centers, private clouds and/or public clouds. While bringing benefits for services in many ways, this increases complexity for managing and operating application delivery as services and resources are distributed globally across multiple clouds and data centers. That motivates IT operators to move towards software-defined data center (SDDC) architectures, using DevOps tools and automation approaches.

Until recently, online technology was just one area of a larger set of teaching tools and methods. While 63 percent of K-12 educators used technology in the classroom daily, primarily laptops and computers, it was still entirely possible to give lessons with nothing more than a strong voice and an engaging manner. The shift to remote learning has transformed this picture toward the digitalization. Connectivity is no longer an option—it’s now the platform through which the entire school experience is going to be delivered for millions of students nationwide. This has made network performance and application availability absolutely critical for schools and districts. There are a couple of ways to keep up using application delivery techniques including load balancing and application security.

But the worst thing about DDoS attacks is that just when you’ve built up your DDoS protection against known attacks, along comes yet another new attack. Such has been the case with NXNSAttack, a DNS DDoS attack that relies on a built-in weakness of the Domain Name System (DNS).
