1. Change the default passwords as most network devices have a pre-configured default password and these are easily found online.

2. Install a firewall directly onto your wireless devices (a host-based firewall). Attackers who directly intercept your wireless network may be able to by-pass your network firewall and so this does not offer sufficient protection.

3. Restrict access — only allow authorised users to access your network. Each piece of hardware connected to a network has a MAC (media access control) address. Restrict or allow access to your network by filtering MAC addresses. The MAC address is a unique identifier for networking hardware such as wireless network adapters. A hacker can capture details about a MAC address from your network and pretend to be that device to connect to your network. MAC filtering will still protect you from majority of the hackers. Find the MAC address for your network adapters on your devices by following these steps:

1. Go to Start > Run

2. Type command and press [Enter]

3. Type ipconfig /all in the command prompt window and press [Enter]

4. You can view the physical access address in the information displayed.

4. Check the user documentation to get specific information about the MAC Filtering process if you have any more queries.

5. Encrypt the data on your network. Encrypting the data would prevent anyone who might somehow be able to access your network from viewing your data.

6. Protect your SSID (Service Set Identifier — An SSID is the name of a WLAN). The SSID on wireless clients can be set either manually, by entering the SSID into the client network settings, or automatically, by leaving the SSID unspecified or blank. A network administrator often uses a public SSID that is set on the access point and broadcast to all wireless devices in range. You can disable the automatic SSID broadcast feature to improve network security.

Sites like Digg, Del.icio.us, and Backflip allow registered users to store all of their bookmarks in one location online, which allows them to access their bookmarks from any place that has Internet access, regardless of the web browser they use. These sites also add customization and interactivity to this feature where users can post and make comments about popular links on the site. These sites are popular because users can customize and control their online experience by storing any of the many websites they see in a day, all in one place. Users also love this technology because they can share their bookmarks with others.

Websites can cater to this market by making linking to various articles easy to do. For example, if a user were to read an interesting article on the New York Times website, he or she can easily save the link to the social bookmarking site of choice. The more people who bookmark the same link, the more popular the link becomes. An article’s popularity can bring in significant traffic to a site. If a website includes articles and other updated content, learning the ins and outs of social bookmarking sites can add value to the quest for website visitors. Catering to these sites is free and can potentially bring in a lot of traffic.

Some Web marketers will use social bookmarking to increase visibility within search engines, but also within the social bookmarking site itself. Imagine that a webmaster posted an interesting article on his site. People visit this article frequently and mark the link to that article in their social bookmarking accounts. Now search engines will know that his website is well linked and well respected.

Also, because of the popularity of that article, people who visit that social bookmarking site will also come across the article while using the social bookmarking site, making the link even more popular. Social bookmarking can have a profound snowball effect on traffic, which is why social bookmarking is a marketing favorite. Unfortunately, marketers have very little control over this process. They can’t make people mark a site, they can only entice them. This is why being mindful of having good, useable content is still important.

When it comes to smartphones, which is the best OS? Is it the open source Android? Is it the newcomer WebOS? Or is it the old stalwart Windows Mobile? Let’s take a look.

HTC HD2

At a huge 4.3 inches, the screen on the HTC HD2 truly is immense, and the high, 800×480 resolution makes it genuinely easy to use things like scrollbars in menus. However, the HTC HD2 actually does a very good job of making it so you don’t have to go into standard Windows menus that often, as on top of the operating system, the interface is HTC’s patented TouchFLO 3D setup, where everything is achieved through various finger swipes and sweeping gestures. It is truly intuitive, and it (along with the truly awesome 1GHz Snapdragon processor) is the reason why the HTC HD2 is such an unmitigated joy to use. Of course, it’s not all about being pretty, a phone needs to have decent features and the HTC HD2 has them in spades, from the 5 megapixel camera, through GPS, to incredibly fast HSDPA internet access (not to mention the superb Opera Mobile web browser).

HTC Hero

The HTC Hero is comparable to the HD2, sharing a similar keyboard-less design. Again, it’s with the software that the HTC Hero shines, with Android living up to the title some have given it, that of ‘game changer’. Its completely open source nature makes adapting the OS very easy, and the interface itself is once again a finger-friendly, sleek, and polished affair, with gesture controls the order of the day. The tight integration of the full Google suite (including Apps and Gmail), makes it a real force to be reckoned with, and it has to be said that the HTC Hero is a truly stunning phone.

Palm Pre

So, there’s the HTC Touch Diamond2, which takes Windows Mobile to new heights. And then, there’s the HTC Hero, which gives Android a new interface. What does the Palm Pre offer that’s different? Well, one could talk about the WebOS interface it uses, as it’s unique in the annals of phone history. And indeed, there’s one feature of WebOS, directly related to the keyboard, that makes the Palm Pre so cool. Universal search. Now, many phones do that, but the Palm Pre does it so much more cleverly. Just start typing what you want to know about, from the front screen, and the Palm Pre will search your contacts, apps, music, pictures, and even the internet, to interpret and find what you’re looking for. That really is a cool feature, and it may well make the Palm Pre the coolest QWERTY phone out there. If you value the interface above all else, the Palm Pre is the phone for you.

 

With the rapidly improving and expanding technology of today, people tend to replace their personal computers on a regular basis in order to keep up with the latest advancements. It’s extremely important to dispose of old IT equipment securely and properly not only to protect your sensitive information, but to protect the precious environment as well.

In early 2007 the Waste Electrical and Electronic Equipment (WEEE) regulations came into effect in an attempt to minimise the millions of tonnes of electronic waste, or e-waste as it’s often called, that is disposed of each year in just the UK alone. You can read about those laws at the Environment Agency’s website.

All computer equipment contains hazardous materials and keeping e-waste out of landfills should be high on the list of priorities of government officials and private citizens everywhere.

Mercury, lead, cadmium and hexavalent chromium, not to mention glass and plastic, all of which have a negative impact on the environment, are just some of what’s found lurking inside our computers, monitors, hard drives, circuit boards, printers, scanners, fax machines, and telephones.

Many areas now have recyclers who will take old IT equipment as well as organisations who specialise in disposing of computers and other hardware in an environmentally responsible way. Other places like not-for-profit organisations will dismantle the computers and salvage whatever parts possible or perhaps make repairs and then resell the equipment. Before donating a computer, make it a point to call in advance, especially if the equipment is obsolete or in disrepair, to see if there’s a need first.

You can find a list of computer recyclers and refurbishers in the UK through a website called ‘Waste Online’

Before using an e-waste disposal service check to see that the company complies with the WEEE regulations and file your written proof that your IT equipment was indeed disposed of securely and properly. And, if you’re donating to a charitable organisation, see that the appropriate security measures will be taken with your equipment to prevent unauthorised access, now a legal requirement thanks to the Data Protection Act of 1998.

Also, some computer manufacturers now offer recycling programs at low or no cost and information about these services, if available, can be found on their respective websites. Some computer makers offer credits toward the purchase of new equipment while others provide the service free of charge.

Erasing the Hard Drive Before Getting Rid of Your Computer

Most of us have done banking or ordered something online using our bank accounts or credit cards and many of us keep track of our finances with files saved on our home computers. Be aware that reformatting the computer’s hard drive is not enough to ensure that all of your data will really be removed from the machine.

There are software programs available designed specifically for this purpose and there’s always the alternative of physically destroying the computer’s hard drive making it unreadable, which of course, won’t be an option if you’re donating the computer to an organisation for some purpose.

However you ultimately decide to dispose of your useless IT equipment it is imperative to be absolutely certain that none of your information will wind up in the hands of a criminal.
