Mobile computing refers to the use of small and portable computing devices in wireless enabled networks that provide wireless connections to a central main server. These devices include laptops, notebook PCs, tablet PCs, palmtops, personal digital assistant (PDAs) and other hand held devices. A radio-signaling device is installed inside these devices for receiving and transmitting electronic data.

Wireless networks use Wi-Fi(wireless fidelity) technology for providing network coverage to offices, public places, and other small workplaces. A wireless access point device is used to provide wire free network coverage in the designated area. An access point device that is built on 802.11b and 802.11g IEEE (Institute of Electrical and Electronics Engineers) standards transmits data at 2.4 GHz whereas devices that comply with 802.11a standards transmit at 5 GHz.

WiMax (Wireless Interoperability for Microwave Access) technology represents the next generation of wireless networking and can transmit data up to a distance of forty-eight km. It can provide a maximum networking speed of seventy Mbps. It provides much better facilities than Wi-Fi such as higher bandwidth and high data security by using enhanced encryption schemes. It can provide service in both Line Of Sight (LOS) and Non-Line Of Sight (NLOS) locations, but range may vary accordingly. WiMax supports several communication protocols, and can act as the backbone network for an ISP(Internet service provider) as well as telecom service provider.

Mobile computing devices can use any of these networks to access the Internet or connect to a LAN( local area network) or WAN(wide area network) server. They use networking software for adjusting device settings to suit specific network requirements.

Mobile computing has enabled users to remain connected while on the move. High end users can opt for satellite based networking which provides wireless connectivity anywhere in the world. However, this technology is costly and will take many years to become as affordable as Wi-Fi and WiMax.

Many users have thrown away their popular Pogo Sketch stylus and upgraded to the AluPen. The AluPen is available in six colors and retails for about $25.

Information security provides a pretty well understood set of standard protection measures going back to the NSA’s rainbow series of publications. Where do the new mobile computing operating stems fall in comparison to the older personal computer and server operating systems? In the first place, the degree of integrating/bundling in the newer systems is vastly different than was routine in earlier generations, so any comparison is certainly not oranges to oranges. Security has had a bad reputation for years as hard to understand and being user unfriendly/unacceptable. Mobile computing is very much based on ease of use and user friendliness, the bottom line then becomes security features need a lot of work to be brought up to acceptable standards, it is certainly a truly great opportunity and challenge.

Still, certain capabilities are desirable, including:

User logon, but at least authentication, some means of verifying user identity is highly desirable. The anonymous user is a very difficult idea. A user friendly way to manage authentication data is also needed, equivalent to but hopefully more capable than the old password management subsystems.

Account management, user accounts need tools to enable ease of use and management of account parameters.

Accountability, the ability to make a user responsible for actions requested by and performed on behalf of the user is a baseline need.

Access control. Mediation of access to resources on a prior granted basis needs a lot of thought, although the basic idea is fundamental. Making it user friendly is the problem/challenge.

Encryption for the protection of communications is a baseline need for mobile platforms. Key management is rather like access control, it needs lots of thought to come up with a user friendly solution. VPN and SSL seem to be becoming the standard solution set.

Backup and restore. The ability to make copies of data that can be retrieved if the originals are damaged or lost is a baseline requirement. Cloud based solutions provide one approach.

Encryption for storage is a desirable capability given the risk of data theft accompanying the risk of device theft.

Remote device reset is an interesting risk management idea to mediate/minimize data theft risks.

Privileges and roles. The notion that certain capabilities should be set aside for a small number of trusted individuals is a server concept, Roles are perceived as a nuisance by many, so work needs to go into the implementation to make any solution acceptable

Future needs. It doesn’t take a crystal ball to see risk management related needs that do not justify major investment today but that soon could.

Malware management. The integrity issues associated with malware infections are beyond normal antivirus. As apps are added, risk intensifies, therefore an advanced solution is going to be needed, not today, but some day, probably soon.

Firewalls, some way to manage network connections is going to be needed that is easier to use and more capable than personal firewalls.

Data management, the ability to mark data as especially sensitive and worth special protection is needed. This may simply involve re-bundling sets of protection measures to provide more robust protection.

Intrusion detection/prevention, given hacker activity, a capability to alert to suspicious activity is desirable, false positives have been the historic problem, so real thought needs to go into the solution.

Vulnerability management, identifying and eliminating algorithmic vulnerabilities, particularly in operating system configurations has been possible for years, its time it becomes a routine capability.

With the continued increase in the uptake of Smartphones you should consider the security issues. Smartphones are like mini computers. They have the ability to hold data which is accessible via email, a cloud based web app or some sort of internal or external memory storage.

Smartphones are valuable and you need to consider what would happen should your mobile device fall into the wrong hands. Here are five tips on how you can secure your Smartphone

Tip 1: Use Password Protection

It is easy to set password protection on your phone. It is most likely under your phones security settings. If you cannot find the option check online or your phone’s manual to see how to enable this. Most people password protect their computer but do not feel the need to for a mobile device however this is the first security step you should take.

Tip 2: Remotely Wipe Phone Data

After you have secured your mobile phone with a password or pass code you may still want to further protect the data stored on your phone with remote wipe. Remote wipe will wipe the data on your phone and restore all the factory settings. This is not something you would want to do unless you are certain you have lost your phone.

In order to set up remote wipe if you have an iPhone you will need to sign up for a paid account with MobileMe. Then you must set up your phone to enable the wipe should you need it. Android phones running 2.2 have remote wipe built in, but you will also need Exchange. Because remote wipe using Exchange can only be done by an administrator of Exchange a better option would be to use the Mobile Defense app. It’s a free app from the Android Marketplace which will allow you to perform the wipe from the Mobile Defense website.

If your phones uses Windows 7 phones it can be remote wiped using Outlook Web Access.

Tip 3: Do Not Save Sensitive Data

If you use your phone to access your internet banking or log in to all your favourite sites do not set your Smartphone to auto-remember passwords. Should your phone get lost or be picked up by someone else your account can be easily accessed.

Many people have their home and address stored on their phone this information could be used fraudulently if your phone was lost or stolen. However using a password or remote wipe tools, as described above, you can prevent your details being leaked.

Tip 4: Watch What You Click

Smartphones like computers can be affected by malware, computer viruses and phishing scams. If you receive a suspicious email or SMS do not click on any links, just as like you would on your computer. Phishing scams can be used to steal your passwords and important information and are often very cleverly disguised as being from your bank.

Tip 5: Be Careful What You Install

If you download or install a new app make sure it is from a trusted source. The benefit of Smartphones is that there are thousands of applications and games available to extend their functionality. Only use official app stores otherwise you may find some malicious code injected into your app which will pass a virus onto your phone.
