Chrome 17 beta brings speed and security improvements

Google has pushed a new version of Chrome into the beta channel that's designed around improving two of the browser's key aspects: speed and security. The first major change in version 17 is the ability for pages to start loading in the background before a user has even finished typing a URL into the Omnibox address and search bar."If the URL auto-completes to a site you're very likely to visit, Chrome will begin to prerender the page," explained Dominic Hamon, a software engineer at Google, while announcing the browser update. The pre-rendering makes the full site show up almost instantly, according to Google.Chrome 17 Beta: Windows | Mac OS X | LinuxChrome 16 Stable: Windows | Mac OS X | LinuxGoogle also introduced an extension to its Safe Browsing technology that protects users against malicious downloads by analysing executable files, including Windows .exe and .msi files, for known malware. Chrome will issue a warning if a certain file appears to be malicious and will also alert the user if a file is downloaded from a website with a poor reputation for hosting malware-infected files.This protection targets the "social engineering" type of threat, such as the common fake anti-virus product being offered online, but it's still up to the user to proceed with the download or discard it. The database of known malware is relatively small for now but should grow rapidly as the feature moves into the stable release.A number of other  minor changes and the usual slew of bug fixes are also included in Chrome 17 beta. Additionally, Google updated the browser's Stable channel to version 16.0.912.75, closing three high risk security holes.

GSM security vulnerability affects 80 percent of mobile phones worldwide

A new flaw in the GSM (Global System for Mobile Communications) cellular network technology could potentially allow a hacker to gain control of a phone and force the device to send text messages or place phone calls. Criminals could use the exploit to send messages or make the calls to expensive premium phone services, lining their pockets with cash and leaving phone owners to foot the bill.
GSM technology is used by billions of people worldwide and is said to represent about 80 percent of the global mobile market according to Reuters. The latest vulnerability was discovered by Karsten Nohl, head of Germany’s Security Research Labs. Nohl says that his team can perform the attack on hundreds of thousands of phones in a short timeframe.
Nohl will be speaking at a hacking convention in Berlin on Tuesday. Although he isn’t planning to present details of the attack at the show, he notes that the code will likely be replicated within a few weeks.
Similar attacks have been waged on landline phone systems in the past. Hackers will set up bogus 900-type numbers in Africa, Asia and Easter Europe then force thousands of phones to call the numbers, charging ridiculous fees to the phone provider who then passes them on to the owner of the line. Users usually don’t even notice any fraudulent activity until they receive their bill. By that time, the hacker has shut down shop and set up a new operation somewhere else.

Review: Kensington SecureBack Security Case

Kensington is well known for creating laptop locks that can anchor your portable PC to something sturdy to keep it from getting lost or nicked. Its locks have been so successful, in fact, that if you own a laptop it's very likely that it has a small rectangular slot for attaching a Kensington lock to it.

This level of success is certainly impressive - after all not every company has provisions for its products built into most computers. However, this success hasn't translated to the popular tablet, the Apple iPad 2.

Apple's uncompromising focus on streamlining features on its flagship tablet has meant there's no room for a Kensington lock slot. With tablets being just as easy to lose or steal - if not more so - than laptops, Kensington has been keen to come up with a solution. Of course, it also wants to capitalise on the iPad's popularity.

Its solution, the Kensington SecureBack Security Case, isn't that great, unfortunately. It involves a rather unattractive case that clips on to your iPad. With it installed, the once sleek and attractive Apple tablet looks bulky and a bit ugly. Who knows, maybe making the iPad a less attractive gadget is part of Kensington's plan to deter thieves.

But if it keeps your iPad safe, who cares about looks? Well, how well it keeps your iPad protected is a concern. The case itself is rather flimsy and a tiny bit cheap feeling. A determined enough thief wouldn't have much trouble breaking the iPad free.

Verdict

We wouldn't feel completely safe leaving an iPad in a busy café with just the Kensington SecureBack Security Case for security, which makes it pretty much redundant. It may dissuade someone from quickly snatching it, but not much more.

It also doesn't come with the ClickSafe Lock to secure it - essential really for securing the iPad. You need to buy it separately, which is an extra expense.

Use a Webcam As a Remote Security Camera

type="html">

You will need to wirelessly connect the webcam to your computer. A USB wireless transmission kit can join together the webcam to the computer at distances that are not possible using a USB cable. You can get the kit from an electronics store or from a computer store. Neither the webcam nor the computer will be physically modified to work with the USB wireless transmission kit. 

1). Decide where you want to place the webcam; typical locations would be facing a door or window in a part of a home where someone could enter without being seen. Place the webcam on a flat surface. For example, use a table so that the lens on the front of the webcam faces toward the area to be watched.

2). Place the USB wireless transmitter next to the webcam. Plug the transmitter power supply power cord into an outlet. Plug the power port of the power supply into the transmitter power port. Plug the end of the USB cable that is attached to the webcam into the USB input, or one of the USB inputs, on the transmitter.

3). Angle the antenna on the transmitter, if there is one, so that it faces in the general direction of where the computer is located.

4). Place the USB wireless receiver next to the computer. Plug the receiver power supply power cord into an outlet. Plug the power port of the power supply into the receiver power port. Insert one end of a USB cable into the USB receiver USB output. Insert the other end of the USB cable into a USB port on the computer.

5). Angle the antenna on the receiver, if there is one, so that it faces in the general direction of where the transmitter is located. You can now use the software that worked with the webcam when it was directly connected to the computer to view the video from your remote security camera.
