WIPS complements MDM security by blocking personal smart devices

May 27th, 2011

With the explosive growth of smart devices in the enterprise, Mobile Device Management (MDM) is a hot topic among IT departments these days.  In order to secure the network and protect sensitive data on mobile endpoints, many organizations are deploying tools to secure, monitor, and manage smart devices accessing their networks.  Installing an MDM agent on mobile assets gives the IT department the ability to enforce VPNs, remotely wipe data off stolen/lost devices, and ensure that devices under management by the IT staff are running the most current and secure applications.

But is this really enough to protect you?

No.  In today’s “BYOD” (bring your own device) culture, the reality is that personal smart devices will continue to attach to your network. These devices may not have your favorite MDM agents running on them, thus exposing your network and data to security threats again.  Enterprises need a “gatekeeper” control to ensure that only approved devices with an installed MDM agent can attach to the corporate network. By adding a strong WIPS solution to your enterprise security portfolio, you will have the ability to enforce such control and complete your mobile security strategy.

A robust wireless IPS solution (WIPS) will detect, identify and locate unauthorized smart devices connecting to the network, generate a real time alert or even better – block those unmanaged devices from connecting in the first place.  Better yet, a good WIPS will allow you to define your security policy by device type, VLAN, and location.  For example, iPhones could be allowed to connect to the guest network for Internet access, but could still be blocked from accessing the internal network.

Android found vulnerable to sidejacking!

May 18th, 2011

Last Friday, a vulnerability in Google’s ClientLogin Protocol was disclosed that makes most Android users vulnerable to ”sidejacking.” All services (Calender, Contacts, Picasa, Stock Quotes, etc.) that use the Google’s ClientLogin API for “Auto Sync” are vulnerable. 

Sidejacking (aka session hijacking) is not new to Wi-Fi. Firesheep that caused a stir last October is a recent example of a tool demonstrating sidejacking attack against Twitter and Facebook. The latest vulnerability though holds significance given the huge userbase of Android smartphones commonly using their smartphones at Open Wi-Fi hotspots.

AirTight demos PCI and WiFi cloud solutions at NACStech conference

May 12th, 2011

AirTight Networks will be demonstrating cloud-based PCI compliance and Wi-Fi access solutions at the NACStech conference in Las Vegas, May 16-18.

AirTight Cloud Services provides scanning for, detection of, and prevention against rogue access points (APs) and other wireless vulnerabilities to satisfy PCI compliance requirements, while laying the foundation for strategic wireless initiatives in the future.

With AirTight, convenience store operators can deploy secure Wi-Fi access, wireless PCI compliance scanning, and wireless IPS capabilities in a singe device managed from anywhere on the Internet.

AirTight’s combination wireless AP/security sensor provides an affordable, easy-to-deploy and use, scalable Wi-Fi access solutions that can meet their Wi-Fi  needs while maintaining PCI compliance and network security.  This seamless transition gives IT complete control and maximum flexibility to roll out WiFi with no additional equipment to purchase, no additional deployment costs, and without compromising security or PCI compliance.

Offered as a monthly service, costs are kept to a minimum.  Subscription fees include all equipment, support and maintenance, as well as device replacement and upgrades during the term of the contract.

For more information and a live demo of AirTight’s award winning products, please visit AirTight Networks at booth #324 at the NACStech Conference in Las Vegas, May 16-18.

Are Smartphones the New Platform for “Mobile Hacktivism”

May 9th, 2011

There’s been a lot of news in recent weeks surrounding the Sony PlayStation Network breaches.  One of the questions that I have received multiple times since this started is whether or not this was a wireless breach or if wireless was  in any way part of the Sony vulnerability.

From what we understand, no.  It sounds like web servers were compromised.  But could these types of attacks happen over Wi-Fi?  You bet.

“Hacktivists” essentially volunteer to participate in these coordinated attacks. The tools used are often easy to use and freely available.  They just need people willing to join the cause to create the distributed denial of service.   Firewalls are supposed to keep the “bad guys” out, but there is nothing stopping anyone from putting these same tools on a smartphone and carrying out these same attacks from INSIDE an organization, not just remotely from the Internet.

These same techniques used against Sony, MasterCard, and Visa as well as the type of attack that breached TJX can now be launched from personal smart devices (Iphones, Ipads, Androids, etc.) inside your network.   In fact, Gopinath K.N., Director of Engineering at AirTight Networks has demonstrated just this type of scenario at various security conferences and on-line presentations.  See his demo here.

Additionally, smartphone malware can be distributed in the form of an application easily downloaded from the Internet (think of all the gaming and social media apps available for iPhones and Androids). Its really no different than how PCs become infected with worms, viruses and malware by visiting untrusted sites and downloading insecure applications.

Once the malware is installed, if that compromised smart device attaches to the corporate network, the malware can be used to launch a stealthy attack from inside the corporate network – with or without the knowledge or consent of the smart device owner .  Sensitive data could even be sent off-site via the device’s own Wi-Fi or 3G radio.

Considering that smart devices and tablets now outnumber PCs in new sales, this may not be so far fetched.  A major difference between PC security and smart devices is that the tools to detect and defend PCs from these vulnerabilities is significantly more mature and widely deployed then smartphone security in practice today.  Organizations need to determine whether or not unauthorized smartphones are allowed to attach to their Wi-Fi  networks (guest and corporate), and how they will enforce wireless security policies to keep themselves secure.

SMBs, WEP still a target for War Drivers

May 9th, 2011

After the TJX breach, the PCI security council strengthened their wireless security standard in an attempt to prevent such catastrophic incidents from reoccurring.  While some of the largest retailers strengthened their wireless security, small and medium businesses need to take a look at their own security practices because they are just as susceptible, maybe more.  In its annual Data Breach Investigations Report earlier this week, Verizon said “criminals are increasingly hitting smaller businesses as it becomes harder to steal financial data from big companies.”

War-driving is still more common than most people probably think, but the number of incidents reported by small and medium businesses is very low.  In most cases, WEP encryption is still the target.  In a recent Network World article reported that Seattle police are investigating a group of criminals attacking local businesses via Wi-Fi access points encrypted with the flawed WEP protocol.  Does this appear to be an isolated incident? No.  According to the Seattle police, this group of criminals has been suspected of these types wireless attacks for as many as *5 years*.

What is troubling is the number of retailers that continue to opt for a “compensating control” to address their wireless security requirements.  Even PCI’s “approved” methods including quarterly wireless scans and visual inspections are insufficient to protect your business.   Wi-Fi is everywhere, its easy to find an unencrypted (or poorly encrypted) signal.

Until companies understand the risk of properly secured Wi-Fi, they will remain susceptible.    Just ask the guys in Seattle.
