It's that time of the year again. The flood of email alerts showcasing online holiday shopping deals fill the inbox at your office PC, laptops and wireless devices as merchants attempt to lure online shoppers to "click and save" while supplies last. In fact, reports show that this year's "holiday shopping" deals have already started as retailers attempt to stretch the holiday shopping season - to begin even earlier than Black Friday.
According to a recent report in Time, Booz & Co. chief retail strategist, Thom Blischok states. "We're not going to see a huge increase in sales growth for Black Friday this year....What we do expect is a lot of ‘showcasing' on Black Friday. Shoppers will check things out in stores, electronics especially, but then purchase online on the Monday after. Cyber Monday sales will explode this year."
While this is good news for merchants, it can become a virtual nightmare for corporate network administrators. With millions of online shoppers turning their office PCs, laptops, and wireless devices into online shopping carts, they hog valuable network bandwidth meant for corporate applications such as e-mail, SAP, Salesforce, and other business-critical applications.
The onslaught of personal smartphones and tablets connecting to corporate networks fully capable of performing browser-based shopping are further affecting normal business operations. According to ABI Research, more than 36 percent of consumers own at least three wireless devices. eCommerce merchants now alert wired consumers with daily deals almost instantly via mobile marketing. This surge has placed greater demands on network monitoring solutions as the mobile device market continues to grow at an astounding rate of five billion subscribers worldwide.
Most organizations allowing employee-owned devices onto their corporate networks (73% according to Aberdeen) find it not only drains their bandwidth, but also opens up severe internal security threats to proprietary information stored on the network. Employers assume this as increased productivity for employees armed with mobile devices and cost savings for hardware not purchased by the corporate office as most employees (54 percent, according to Yankee Group) demand to use their own devices at work.
According to IDC Research, however, 30-40 percent of Internet use in the workplace is non-business related. Vault.com found 37 percent of workers admit to surfing the Web constantly at work for personal interests. This underscores the need for mobile device traffic monitoring. How can network admins monitor employee internet usage and take corrective action?
Companies can easily set guidelines for network traffic monitoring to safeguard against employees armed with BYOD - especially during high traffic holiday shopping/sale months - in a few easy steps.
MAC Addresses and Mobile Devices
The old and sort of cumbersome way is to monitor the unique MAC addresses that are used by each smart mobile device that accesses an Ethernet network. The 6 byte (i.e., 48 bit) MAC address is generally in two parts: The first 3 bytes are the MAC Address vendor ID generally shared by hundreds or even tens of thousands of devices produced by the manufacturer; the second set of three bytes are unique to the device.
A 48-bit Ethernet MAC address has two components, each of which is 24 bits:
*24-bit Organizational Unique Identifier (OUIIEEE regulates the assignment of OUI numbers. Within the OUI, the two following bits have meaning only when used in the destination address:
- Broadcast or multicast bit - indicates to the receiving interface the frame is destined a group of end stations on the LAN segment.
- Locally administered address bit - normally combines OUI and a 24-bit station address. This is universally unique; however, if the address is modified locally, this bit should be set. Some vendors like Apple set this bit automatically.
Generally, the MAC address is not changed by the end user, thus dynamic IP addresses are often not used to track or report on mobile phone devices. Organizations using NetFlow and IPIX can in fact track these MAC addresses.
MAC Addresses and NetFlow
Traditional flow data (e.g., NetFlow v5) exports IP addresses, but not MAC addresses. NetFlow v9 and IPFIX introduce the ability to export any information on the router including MAC address.
A reliable Network Traffic Analyzer can be used to report to report on NetFlow and IPFIX. The NetFlow Analyzer should offer a filtering architecture to allow traffic analysts to include or exclude portions of MAC addresses. If the administrator wants to narrow a particular vendor (e.g., 00.00.0c) or the iPhone (e.g., 60:33:4b, 64.b9.38, etc.), a reporting tool can filter on these vendor IDs. Once vendor IDs are added to the report, the type can be changed to view different reports. For example, the top domains these mobile devices are visiting can be obtained if the router, switch, or firewall exporting the NetFlow or IPFIX includes URL information. The IT manager can often click on the domain (e.g. facebook.com) and look at URLs visited with mobile device.
By forcing users to authenticate all devices onto the network and agreeing to an operating system scan, network administrators can maintain an active inventory of who (i.e., username) authenticated onto the network and with what type of device. Detailed reports can be run on the volume of iPhones, Androids, Blackberries, iPads, etc. that have authenticated onto the network. Since the MAC address is obtained from every authenticated device, it can be cross referenced with the NetFlow and IPFIX received to look at traffic patterns. This is a much more scalable solution and less error prone approach than the traditional track-down-all-the-mac-addresses approach.
Smartphones: Network Security Challenge
Allowing smartphone access to corporate resources often requires adapting new corporate mobile strategies and policies. Many companies provide VPN access to the corporate network from computers when working remotely. While VPNs offer a secure connection by encapsulating data, many smartphones don't support them (e.g., iPhone). This is partly because the hardware doesn't have the processing power to keep up with encryption processes on-the-fly. Due to pressure from management and remote users, VPN enforcement is often lax. Most employees obtain corporate access from any public network, which includes public places like local coffee shops. This opens Pandora's Box when it comes to security threats.
Smartphones are an ideal tool for cybercriminals to push their malware, viruses, worms and other threats onto corporate networks. With many important titles, email addresses and phone numbers sitting on just about every network-capable mobile phone, stealing confidential emails or pushing botnets onto the company network is easier with traditional security measures put aside in favor of easy remote access. With smartphone synchronization, infection can easily migrate onto a PC - a Trojan horse method that infects the PC could provide access to the corporate network. On the other hand, the data carried on smartphones can be targeted through malware on PCs.
Direct Attacks on the Mobile Phone
Some employees try to increase the security of their phone with special anti-theft software or by encrypting their memory card. These solutions are aimed at making data protected from physical attacks. However, those are done by pickpockets, who are less interested in the mobile phone content than reusing or reselling the device.
Cybercriminals do care about sensitive information stored on smartphones, but they don't need physical access to the phone to retrieve it. Rather, they will exploit any vulnerability - for instance in the phone's Web browser (such as the WebKit vulnerabilities on Android phones) - or use social engineering tricks to install malware on the phone. Once the phone is infected, it's easy for the cybercriminal to access any data on the device. In those cases, the locks are useless and the memory card is dynamically decrypted when used.
Businesses must add employees to the corporate network easily and cost-effectively while maintaining desired security levels and remote management capabilities. Traditionally, the RIM BlackBerry Enterprise Server (BES) has been the gold standard among organizations with corporate-liable policies, providing sophisticated security and management capabilities.
However, smartphones like Androids and iPhones are becoming more popular, and some organizations feel obligated to embrace these as part of the employee-owned smartphone strategy. These are also supporting minimum security requirements, like timed-lock and remote wipe in the case of a lost or stolen handset. Some mobile apps, like Touchdown for Android, provide Exchange ActiveSync capabilities that support security policies to ensure security of the corporate data on the smartphone. Clearly, organizations need to rethink their mobile Smartphone strategies and take into account the proliferation of employee-owned smartphones.
Setting up single sign-on is another strategy that could be implemented on corporate networks. However, as of today, it's not supported on the iPhone. Whatever the decision, a careful evaluation of mobile devices accessing the network needs to be executed.
Ultimately, the question is: Do employees really need access to the corporate network via their smartphones? If they are provided access, then IT must secure the network to make sure the onslaught of online holiday shopping and sales offerings don't turn the season to "nightmare" before Christmas for the network bandwidth.
So, this holiday season, stay safe out there and don't forget to drive safe - on the road and in cyberspace.

The essence of data analysis involves setting up data pipelines that consist of several operations that are chained together – starting from data collection, data quality checks, data integration, data analysis and data visualization (including the setting up of interaction paths in that visualization). In our opinion, the challenges stem from the technology diversity at each stage of the data pipeline as well as the lack of process around the analysis.
