Water-authority network upgrade spots problems faster

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

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…

Report: 5G network slicing could leave flaws for bad actors to exploit

5G networks that incorporate legacy technology could be vulnerable to compromise via a lack of mapping between transport and application layers, according to a report by Ireland-based AdaptiveMobile Security.
5G resources

What is 5G? Fast wireless technology for enterprises and phones
How 5G frequency affects range and speed
Private 5G can solve some problems that Wi-Fi can’t
Private 5G keeps Whirlpool driverless vehicles rolling
5G can make for cost-effective private backhaul
CBRS can bring private 5G to enterprises

Network slicing is central to realizing many of 5G’s more ambitious capabilities because it enables individual access points or base stations to subdivide networks into multiple logical sections—slices—effectively providing entirely separate networks for multiple uses. The slices can be used for different purposes—say, mobile broadband for end-users and massive IoT connectivity—at the same time, without interfering with each other.To read this article in full, please click here READ MORE HERE…

5 free network-vulnerability scanners

Though you may know and follow basic security measures on your own when installing and managing your network and websites, you’ll never be able to keep up with and catch all the vulnerabilities by yourself.Vulnerability scanners can help you automate security auditing and can play a crucial part in your IT security. They can scan your network and websites for up to thousands of different security risks, producing a prioritized list of those you should patch, describe the vulnerabilities, and give steps on how to remediate them. Some can even automate the patching process.Though vulnerability scanners and security auditing tools can cost a fortune, there are free options as well. Some only look at specific vulnerabilities or limit how many hosts can be scanned but there are also those that offer broad IT security scanning.To read this article in full, please click here READ MORE HERE…
