How to buy Wi-Fi 6 access points

November 29, 2021 TH Author Network Security, Networking, Wi-fi

Wi-Fi 6 has some impressive improvements over its predecessor Wi-Fi 5 including lower latency, faster speeds, higher throughput, and increased range that can make it a better fit to serve both dense clusters of clients and clients running high-bandwidth applications.As Wi-Fi in general replaces wired networks in some enterprises and with the increased use of tablets, laptops, and mobile phones within enterprises, wireless-network responsiveness and versatility are becoming more desirable. Wi-Fi 6 (802.11 ax) can help. It can also improve the efficiency of IoT Wi-Fi networks by letting sensors lie idle more of the time so their batteries last longer.To read this article in full, please click here READ MORE HERE…

‘FragAttack’ flaws threaten Wi-Fi, but not too seriously

May 14, 2021 TH Author Networking, Security, Wi-fi

Almost all Wi-Fi is potentially vulnerable to flaws that date back to 1997 when it became commercially available, but even the person who discovered the weaknesses says some of them are difficult to exploit.

Mathy Vanhoef, a post-doctoral student at NYU Abu Dhabi, has created attacks—FragAttacks—that take advantage of the vulnerabilities, but in an academic paper about them, says the most widespread vulnerabilities can be exploited only under specific, rare conditions, and require either user interaction or highly unusual configurations to succeed.To read this article in full, please click here READ MORE HERE…

802.1X: What you need to know about this LAN-authentication standard

April 28, 2021 TH Author access control, Network Security, Networking, Wi-fi

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…

Wi-Fi in 2025: It could be watching your every move

April 26, 2021 TH Author Networking, Security, Wi-fi

I consider myself a techno-optimist. Technology has improved life for humanity in countless ways, like the wheel, the printing press, selfie sticks—these marvels have enriched us all.So too has Wi-Fi. If not for Wi-Fi, no one could idly stream YouTube videos on company laptops through rogue hotspots at a busy-but-socially-distanced coffeeshop when we’re supposed to be doing our jobs. Which is to say none of us could fully leverage the remote network-connectivity tools that allow enterprise employees to be productive any time and from anywhere.To read this article in full, please click here READ MORE HERE…

Wi-Fi: How to deploy 802.1x authentication using WPA3-Enterprise

December 28, 2020 TH Author Networking, Security, Wi-fi

Wi-Fi Protected Access 3 (WPA3) has brought significant security improvements to Wi-Fi networks, particularly WPA-3Enterprise, which includes tweaks to make authenticating to the network more secure. One of these is has to do with 802.1x authentication that is used to determine whether Wi-Fi clients will be granted access to the enterprise network.
Wi-Fi resources

The enterprise mode of WPA has always allowed you to give each user a unique username/password to login to the Wi-Fi or to utilize unique digital certificates for each user to install on devices for even more security. Now with WPA3-Enterprise, the security is increased as clients are now required to make sure it’s communicating with the real authentication server before sending login credentials. That verification was optional with the earlier two versions of WPA.To read this article in full, please click here READ MORE HERE…

When it comes to the IoT, Wi-Fi has the best security

July 24, 2019 TH Author Internet of Things, Networking, Security, Wi-fi

When it comes to connecting internet of things (IoT) devices, there is a wide variety of networks to choose from, each with its own set of capabilities, advantages and disadvantages, and ideal use cases. Good ol’ Wi-Fi is often seen as a default networking choice, available in many places, but of limited range and not particularly suited for IoT implementations.According to Aerohive Networks, however, Wi-Fi is “evolving to help IT address security complexities and challenges associated with IoT devices.” Aerohive sells cloud-managed networking solutions and was acquired recently by software-defined networking company Extreme Networks for some $272 million. And Aerohive’s director of product marketing, Mathew Edwards, told me via email that Wi-Fi brings a number of security advantages compared to other IoT networking choices.To read this article in full, please click here READ MORE HERE…

Cisco warns WLAN controller, 9000 series router and IOS/XE users to patch urgent security holes

April 18, 2019 TH Author router, Security, Wi-fi

Cisco this week issued 31 security advisories but directed customer attention to “critical” patches for its IOS and IOS XE Software Cluster Management and IOS software for Cisco ASR 9000 Series routers. A number of other vulnerabilities also need attention if customers are running Cisco Wireless LAN Controllers.The first critical patch has to do with a vulnerability in the Cisco Cluster Management Protocol (CMP) processing code in Cisco IOS and Cisco IOS XE Software that could allow an unauthenticated, remote attacker to send malformed CMP-specific Telnet options while establishing a Telnet session with an affected Cisco device configured to accept Telnet connections. An exploit could allow an attacker to execute arbitrary code and obtain full control of the device or cause a reload of the affected device, Cisco said.To read this article in full, please click here READ MORE HERE…

How to hack your own Wi-Fi network

March 26, 2019 TH Author MDM, Open Source, Security, Wi-fi

One way to bolster your understanding of Wi-Fi security is to do some hacking yourself. That doesn’t mean you should infiltrate a company’s network or snoop on a neighbor’s setup. Rather, ethical hacking and legitimate Wi-Fi penetration testing – done in cooperation with the network owner – can help you learn more about the strengths and limitations of wireless security. Understanding potential Wi-Fi vulnerabilities can help you to better protect the networks you manage and ensure safer connections when you access other wireless networks.Start with a Wi-Fi stumbler
General purpose Wi-Fi stumblers are the simplest and most innocent tools to add to your pen testing kit. Though typically passive tools, they serve an important purpose. They allow you to see what access points (AP) are nearby and their details, such as the signal level, security/encryption type, and media access control (MAC) address. It’s a tool even a hacker would utilize to find the next victim.To read this article in full, please click here READ MORE HERE…

What is WPA3? Wi-Fi security protocol strengthens connections

November 2, 2018 TH Author Mobile&Wireless, Security, Wi-fi

The Wi-Fi Alliance has introduced the first major security improvement to Wi-Fi in about 14 years: WPA3. The most significant additions to the new security protocol are greater protection for simple passwords, individualized encryption for personal and open networks, and even more secure encryption for enterprise networks.The original Wi-Fi Protected Access (WPA) standard was released back in 2003 to replace WEP, and the second edition of WPA came the year after. The third edition of WPA is a long-awaited and much-welcomed update that will benefit Wi-Fi industry, businesses, and the millions of average Wi-Fi users around the world—even though they might not know it.To read this article in full, please click here READ MORE HERE…
