Erosion of the traditional network perimeter and the transition to work-from-anywhere have conspired to bring an unprecedented threat level to endpoint devices, users, and applications, Cisco CEO Chuck Robbins told the online audience at the virtual RSA Conference 2021.Such threats are exacerbated by the fact that over 3,500 vendors offer security products and services that many customers patchwork together, creating complexity that makes it hard for many to build an effective security position, Robbins said.Backup lessons from a cloud-storage disaster
Against that backdrop, Cisco announced a number of security moves to further integrate and upgrade its own overarching offerings with new features and services.To read this article in full, please click here READ MORE HERE…

When devics on enterprise LANs need to connect to other devices, they need a standard method for identifying each other to ensure they are communicating with the device they want to, and that’s what 802.1x does. This article tells where it came from and how it works.802.1x defined
IEEE 802.1X is a standard that defines how to provide authentication for devices that connect with other devices on local area networks (LANs).How to deploy 802.1x for Wi-Fi using WPA3 enterprise
It provides a mechanism by which network switches and access points can hand off authentication duties to a specialized authentication server, like a RADIUS server, so that device authentication on a network can be managed and updated centrally, rather than distributed across multiple pieces of networking hardware.To read this article in full, please click here READ MORE HERE…

April 19, 2021 TH Author Internet of Things, Network Monitoring, Network Security, Network Switch

The Albuquerque water authority says recent network upgrades give it greater visibility and control over its remote sites and makes for faster responses to leaks and other problems.The Albuquerque Bernalillo County Water Utility Authority manages more than 3,000 miles of water-supply pipeline covering more than 650,000 users. The authority manages 135 remote locations, which include well sites, tanks, and pump stations, all of which have programmable logic controllers (PLC) connected to a dedicated, fixed-wireless network running at 900MHz back to the core network.[Get regularly scheduled insights by signing up for Network World newsletters.]
“The [main treatment] plant was built [about] 15 years ago,” said Kristen Sanders, the authority’s chief information security officer. “So if a piece of equipment went out, replacing it would be about shopping on eBay.” Also the authority’s fiber backbone that connects the sites with the main plant was past it’s service life and had to be replaced.To read this article in full, please click here READ MORE HERE…

TCP/IP stack vulnerabilities threaten IoT devices

April 16, 2021 TH Author Internet of Things, Network Security

A set of vulnerabilities in TCP/IP stacks used by FreeBSD and three popular real-time operating systems designed for the IoT was revealed this week by security vendor Forescout and JSOF Research. The nine vulnerabilities could potentially affect 100 million devices in the wild.Nucleus NET, IPNet and NetX are the other operating systems affected by the vulnerabilities, which a joint report issued by Forescout and JSOF dubbed Name:Wreck.In a report on the vulnerabilities, Forescout writes that TCP/IP stacks are particularly vulnerable for several reasons, including widespread use, the fact that many such stacks were created a long time ago, and the fact that they make an attractive attack surface, thanks to unauthenticated functionality and protocols that cross network perimeters.To read this article in full, please click here READ MORE HERE…
