Universal zero trust network access (UZTNA) is the use of ZTNA for on-premises and remote users, with no distinction made as to the user’s location. With universal ZTNA users are granted secure access based on the principle of least privilege whether they’re working in the office, at home, or on the road. UZTNA can serve as a conduit for digital transformation, giving organizations the best possible framework for zero trust initiatives.
5G security is an area of wireless network security focused on fifth-generation (5G) wireless networks. 5G security technologies help protect 5G infrastructure and 5G-enabled devices against data loss, cyberattacks, hackers, malware, and other threats. Compared to previous generations, 5G makes greater use of virtualization, network slicing, and software-defined networking (SDN), making it vulnerable to new kinds of attacks.
The difference between SD-WAN and MPLS is that SD-WAN is a virtualized network overlay that can combine multiple types of connections, whereas MPLS is a dedicated, hardware-based private network. Furthermore, SD-WAN creates encrypted tunnels over the internet, while MPLS doesn’t directly support encryption but is partitioned from the internet. Today, it’s widely agreed that SD-WAN is more cost-effective, flexible, and secure than MPLS.
The SolarWinds cyberattack was a software supply chain attack involving the SolarWinds Orion platform, wherein a Russian nation-state adversary gained access to SolarWinds systems and deployed trojanized updates to the Orion software. This, in turn, allowed threat actors to install stealthy malware on SolarWinds customers’ networks. The SolarWinds hack was disclosed by multiple cybersecurity companies in conjunction with the US Cybersecurity and Infrastructure Security Agency (CISA) in December 2020.
