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

TH Author ,

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…

Ransomware: How to make sure backups are ready for a real attack

TH Author , ,

The best way to avoid paying ransom to attackers who have infected your systems with ransomware is to have those systems adequately backed up so you can wipe them and restore them from safe backups. Here are several options for making sure those backups are up to the task.In this article, backup refers to any system that you’re going to use to respond to a ransomware attack, including old-school backup systems, replication systems, and modern hybrid systems that support backup and disaster recover. For simplicity’s sake, they’ll all be referred to as backup here.

5 free network-vulnerability scanners

TH Author , ,

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

TH Author ,

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…

How COVID-19 is shaping enterprise networking

TH Author , ,

The COVID-19 pandemic has influenced the networking arena in a number of ways, including the rise of fully automated remote offices, the need to support a “branch of one,” and the growth of new communications software tools.”One of the biggest trends we are seeing is business agility. That is, IT looking at the tech they have deployed and evaluating it not just in terms of speeds and feeds, but how agile it is to handle whatever’s coming next,” said Todd Nightingale, Cisco’s Enterprise Networking & Cloud business chief. “Software APIs are a huge part of that trend, because it is amazingly easier to handle changes through APIs and software that make it possible to change things in a day rather than months.”To read this article in full, please click here READ MORE HERE…
