Tips to make your browser secure

Web browsers are the key to the internet. Without them the internet is an impenetrable black box.

Browsers may be among the most commonly used applications, but they also offer the greatest number of attack options for dangerous content on the net. To keep viruses, worms and other malware away from your computer when surfing, it's crucial to configure your browser for security.

The firewall on a DSL router is a good first step for protecting the computer during surfing, says Marco Rinne from the computer portal chip.de. But that doesn't hold true if your browser is out of date: “Internet Explorer 6 and 7 or Firefox 2 no longer satisfy current security standards,” he says. For optimal protection, he therefore urges users to keep their browsers updated.

There are numerous security tools already present in Firefox and Internet Explorer. The pop-up blocker, for example, prevents more than just annoying ads. It also throttles other windows that can be used to sneak malicious software onto PCs. Phishing filters protect personal data against theft.

Firefox offers additional configuration options under the Settings item in the Security tab of the Options dialog box: this includes the ability to block risky or forged websites. It's also a good idea to prohibit websites from installing add-ons on their own. Similar settings are possible under Internet Explorer in the Security tab of the Internet Options dialog box, accessible from the Tools menu.

Computer owners should also activate all options for warning against attacks, advises Markus Linnemann, managing director of the Institute for Internet Security (ifis) at the Polytechnic University of Gelsenkirchen in Germany. This applies in particular to warnings about suspicious content to be displayed using ActiveX, Flash, or JavaScript.

Yet the warning mechanism on most browsers alone isn't usually enough, Linnemann says. Those who wish to be especially careful can, for example, use the Firefox add-on 'No Script,' which blocks all active content of a website by default and allows the user to decide which should be permitted. The problem is that most users are unable to determine which content represents a threat to their computer, Rinnem says.

How to crop an image in photoshop

Cropping is one of the most basic editing techniques that can improve your images. Cropping helps to bring out the most important features in your image and focus the viewers’ attention on these features. Cropping also allows you to make your image a standard photo size.

There are several ways to crop images in Adobe Photoshop:
      1. Cropping with the Crop Tool
      2. Cropping to a specific size
      3. Cropping with the Marquee Tool

CROPPING WITH THE CROP TOOL


The Crop Tool allows you to make a precise selection of an image you wish to edit. To crop with the Crop Tool, follow these steps:

1. Open the image you wish to crop (see Getting Started for detailed instructions).
2. Select the Crop Tool from the Toolbox (see Selection Tools for location and description).
3. Click on your image once and drag the mouse out to make a cropping border.

4. Resize the border by dragging the squares at the sides and corners till you are satisfied with the way your image looks.

NOTE: You can also rotate your cropping border. Move the cursor outside the border, you will see how it turns into a double-headed arrow . Drag the arrows in the directions you wish to rotate your selection.

5. Once you are completely satisfied with your cropped image, press ENTER.

CROPPING TO A SPECIFIC SIZE

If you wish to print your digital photos or other images on standard size photo paper, you will have to crop your images to a specific size, such as 8x10. To crop an image to a specific size, do the following:

1. Open the image you wish to crop.
2. Select the Crop Tool from the Toolbox.
3. In the Options bar, specify the values for Width and Height
4. Click in your image and drag the cropping border. Notice that the border is con strained -you cannot make it wider or longer than the specified values (Figure 4). For example, if you entered 8 for Width and 10 for Height, whatever size you make the border, the area within it will fit on an 8x10 photo.

5. Once you are completely satisfied with your cropped image, press ENTER.

CROPPING WITH THE MARQUEE TOOL

If you are in a hurry and need just a simple crop, you can use the Marquee Tool and a menu command. To crop with the Marquee Tool, follow the steps below:
1. Open the image you wish to crop.
2. Select the Rectangular Marquee Tool from the Toolbox (see Selection Tools).
3. Click in your image and drag the mouse to draw a marquee around the area you wish to crop
4. In the main menu, go to Image > Crop (Fig. 6). The image will be immediately cropped.
