How to Secure a Wireless Network from Hackers?

The reason we secure a wireless network is to stop people from using the services of our network who don’t have permission to utilize them. It is harder to secure a wireless network from hackers as compared to a classic wired network. This is due to the fact that a wireless network can be accessed anywhere inside the range of its antenna.

In order to secure a wireless network from hackers, we should take proper steps to save ourselves against security issues. If you don’t secure a wireless network from hackers, you might end up without its service. The consequence might also include the utilization of our network to attack further networks. To secure a wireless network from hackers, you should follow these simple wireless networking tips:

1. Strategic antenna placement:

The first thing you have to do is to position the access point's antenna in a place which restricts the range of its signal to go further than the required area. You should not put the antenna close to a window because glass can’t obstruct its signals. Place it in a central location of the building.

2. Use WEP:

WEP stands for Wireless encryption protocol. It's a customary technique for encrypting traffic on a wireless network. You should never skip it as that will allow hackers to get instant access to the traffic over a wireless network.

3. Change the SSID, disable the broadcast of SSID:

SSID stands for service set identifier. It is the recognition thread utilized by the wireless access point due to which the customers are capable of starting connections. For every wireless access point arranged, select an exclusive as well as unique SSID. Also, if it’s attainable, hold back the broadcast of the SSID out over the antenna. It won’t appear in the listing of offered networks, while being able to provide services as usual.

4. Disable DHCP:

By doing this, the hackers will have to decode the TCP/IP parameters, subnet mask as well as the IP address in order to hack your wireless network.

5. Disable or modify SNMP settings:

Change the private as well as public community settings of SNMP. You can also just disable it. Otherwise the hackers will be able to utilize SNMP to get significant info regarding your wireless network.

6. Utilize access lists:
For additional security of your wireless network, and if your access point support this feature, employ an access list. An access list lets us determine precisely which machinery is permitted to attach to an access point. The access points which include the access list can employ trivial file transfer protocol (TFTP) now and then in order to download modernized lists to steer clear of hackers.

Paint Shop Picture Tubes

One of the features that I really like about Paint Shop Pro is called Picture Tubes. What this clever invention allows you to do is define an object with one or more graphic images, all the same size. You can then select that tube and click it anywhere in a graphic, depositing one of the pictures at the location where you click. It's a great way to get some random images on a similar theme added to your graphic.
For example, you could create a "butterfly" tube with a hundred images of different butterflies. Now if you want to create a graphic with butterflies you only need select the tube and click around, adding a different butterfly each time.
You can do things like add flowers to a scene or place a few spiders around a picture. You can also fill a pond with frogs, an aquarium with fish or a mountain with animals.
A picture tube contains a set of related objects. For example, a "stars" picture tube might contain a dozen stars, each different, or a "spiders" tube might contain 30 spider pictures.
You can create picture tubes easily using Paint Shop Pro 6.
Using picture tubes is easy also. You simply choose the picture tube tool from the toolbar, set a few options if you want and click on your picture. An image from the picture tube will be placed wherever you click.
An example of the "Tool Options" which you can select for picture tubes is shown above. As you can see, you can select the scale (size) and step (which determines how far apart images are placed when you click and hold).
For an example of using picture tubes, lets suppose you created a blank graphic 400 X 400 pixels in size. You want to populate the image with Easter eggs, so you choose the "PaintedEggs" tube from the "Tool Options" menu. Now, just click around the blank image that you created until you have the desired number of Easter eggs.

Perhaps the really cool thing about picture tubes is that many other people have spent large amounts of time creating wonderful tube collections. Use some of these and you will be able to easily create some incredible graphics with virtually no effort
