Consider this: If you or an employee is using free Wi-Fi in some local café, in a matter of seconds a hacker can manipulate your machine into a "man-in-the-middle" scenario, where the device is now a conduit that sends data right to the bad guy. Once a device is compromised, login credentials (corporate mail server, bank accounts, LinkedIn.com, Facebook.com, etc.) can be harvested by using SSL Stripping.
People sign up for cruise ships to get away from it all. But not quite all: Passengers still want Wi-Fi access for the growing number of mobile devices they lug with them on vacation for staying in touch, web surfing, music, photos and video. Cruise line Royal Caribbean is turning to 802.11ac to optimize their Wi-Fi connectivity for this mobile data deluge.
Georgia Tech researchers have developed a proof-of-concept attack called Jekyll that involves using Trojan Horse-style apps to sneak malware past Apple's app review process and onto iOS devices such as the iPhone and iPad.
Underneath the mobile technology buzz at Mobile World Congress 2013 about expanding LTE deployments, and phasing in even faster LTE-Advanced networks later this year, is the strengthening market in operator-based Wi-Fi services.
Using non-secured public Wi-Fi hotspots can leave you vulnerable to identity theft, data theft, snooping, impersonation and malware infection. That's why so many people rely on public virtual private network services, but VPNs are no panacea. Here are five potential gotchas.
Wi-Fi is inherently susceptible to hacking and eavesdropping, but it can be secure if you use the right <a href="http://www.networkworld.com/topics/security.html">security</a> measures. Unfortunately, the Web is full of outdated advice and myths. But here are some do's and don'ts of Wi-Fi security, addressing some of these myths.
<a href="http://www.vtnews.vt.edu/articles/2011/10/101711-outreach-cybersecurephones.html">Virginia Tech researchers</a> for the past month and a half have been working to customize Google’s Android software to lock down smartphones so that sensitive data isn’t exposed once a user leaves approved locations. They’re hopeful the technology – part of a project dubbed GhostBox -- will be production-ready by year-end.
New research conducted on behalf of the Wi-Fi Alliance shows that while wireless users are making strides on the security front, they’re still leaving their Wi-Fi networks too open to intruders.
A research team at North Carolina State University has proposed a way of measuring the impact of wireless denial-of-service attacks on Wi-Fi networks. It's a step toward building focused counter-measures that can make such attacks costly to pull off.
Cisco is beefing up wireless transaction security with new software features for its Wi-Fi access points. The vendor says the changes add needed protection over and above that mandated by the Payment Card Industry (PCI) standard.
The 802.11n standard was ratified in 2009 and WiFi really took off in 2010, with support showing up in an array of consumer electronic devices. Unfortunately security related issues escalated right along with growing acceptance. Here’s a look back at the WiFi security issues that emerged this year.
Beginning Sept. 30, Visa will require merchants and related businesses to conduct wireless security scans to prove compliance with version 1.2 of the PCI Data Security Standard (PCI DSS) which is designed to safeguard cardholder data from wireless threats.
Apple has done enough security-wise with its iPhone and iPad to make many CSOs comfortable with the mobile devices connecting to corporate networks, but Google's Android still has a ways to go.
Wi-Fi support has made its way into all kinds of consumer devices -- from smartphones to gaming consoles, cameras, DVD players and televisions -- and it is often implemented with native connection sharing capabilities. While great for consumers, this creates security and performance issues when any of these devices end up at work.
