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

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

WAN challenges steer auto-rental firm to SASE

Latency and reliability concerns set car rental company Sixt on a path to rearchitect its WAN. That led the global company, which has locations in more than 100 countries, to become an early adopter of the network-security architecture dubbed secure access service edge (SASE) by research firm Gartner. Tech Spotlight: Security 4 ways to keep the cybersecurity conversation going after the crisis (CSO) Mitigating the hidden risks of digital transformation (CIO) WFH security lessons from the pandemic (Computerworld) WAN challenges steer Sixt to cloud-native SASE deployment (Network World) 6 security risks in software development — and how to address them (InfoWorld) SASE, pronounced "sassy," blends SD-WAN's network optimization features with security capabilities such as zero-trust authentication, data loss prevention, threat detection, and encryption. Driven by demand for a more efficient, scalable network-security architecture, SASE can enable greater network reliability, more flexible deployment options, and pervasive security. The technology is in its infancy but projected to grow quickly. Gartner estimates at least 40% of enterprises will have explicit strategies to adopt SASE by 2024, up from less than 1% at the end of 2018.To read this article in full, please click here
