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

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…

IoT security tips and a cautionary tale

You will have more connected devices than ever on your network in 2021, especially if you’re in healthcare, retail, or logistics, industries that are among the early adopters of the Internet of Things (IoT). You’ll have devices on your network edge, in your headquarters, on vehicles, in machinery, in your stores, in employees’ homes, and on public property.And there’s a good chance that some or many of these IoT devices have built-in security vulnerabilities that can endanger your network. In trying to capitalize on the voracious global appetite for connected commercial devices, many IoT manufacturers and developers are shoveling out enterprise IoT devices with, shall we say, varying levels of regard for security.To read this article in full, please click here READ MORE HERE…
