How Does A Web Proxy Work?

Surely you have heard many times the term proxy, but you didn’t know what it really is and what it does. If you are accessing the Internet from a computer located in a network or an office environment, almost certainly your communications passed through the proxy. But, what is a proxy? Simply: proxy is a layer of software that does the job for a network client. Network client creates the request, and the server responds to the request. For example, your web browser requires web content from a web server: depending on the proxy there are several ways of how proxy might work for the client, and they can be different: reverse proxy, arp proxy, transparent etc. We can understand this when we are visiting a particular website. For instance “www.google.com”. At the bottom, browser displays a message: “Waiting for www.google.com”. That means our web reader connects directly with the specified web server. But if it shows something like “Connecting to 192.171.1.1…” then our communication goes through a proxy.

What are the advantages of using a proxy?

Firstly, the only computer on the network that must have a public IP address is the one on which the proxy is located. In the same time, that means that whole network can have access to the Internet (and it gains safety on the network also). The proxy also improves the flow of information retaining in its cache memory requests of earlier readers. For example, if a user has requested some sort of page, the proxy will copy the contents of its cache. When the next request for that same page arrives to proxy, it shall content from its cache instead of going back to the Internet to download the requested web page. It is important to note that protected content will not be copied into the cache memory. For example, if you give information about your credit card on the site with URL which starts with “https://”, this information will not be stored in the cache of the proxy. Another way in which proxy works “for the sake of” client is as a “transparent” proxy. But, let’s say something about third term: reverse proxy. When user requests information on the Internet by a web server protected by reverse proxy, reverse proxy intercepts the request and checks whether the information contained in the application are acceptable data (such as malicious HTTP commands), and that means: the most common use of reverse proxy is to protect web server.

Free VPN solutions are a good alternative to proxies. They work in a different way but are often as effective, if not more. There are also paid but affordable VPN providers like HideMyAss that are fast, reliable and secure. Watch this HideMyAss review to learn more about this VPN solution.

Top 7 Home Security Tips

When it comes to owning a home, feeling safe and secure is one thing we strive for. No matter how safe we think we are, unfortunate events like robberies are bound to happen. There are very simple safety tips for keeping your home safe.

You should never leave notes for friends, family members, or the lawn service on your front door. This gives robbers the idea that it’s a great time to break in and ransack your home. Instead, you should send a text or call to whoever you are planning on coming to your house.

Hide your valuables in non conspicuous places. The three main places robbers are bound to look are in the master bedroom, your kitchen, and even your living room. Instead, hide your most important items in places such as your basement or attic, or, if you have a den or kids, hide them around the children’s bedrooms and your guest bedroom or den.

If you have an alarm system, never have it installed near windows. When you install your alarm system keypad near a window, robbers can easily look inside, see if it is armed or unarmed, and break the window to get in and unarm the system before escaping out any doors. It is safest to put the alarm somewhere in the living room, near a back wall, or in your kitchen.

Always keep your cars locked up. Whether you have a garage or you don’t, robbers can easily try to steal your car. Always make sure your car is locked up and the windows are rolled up, and, for extra precaution, buy a steering wheel lock so robbers can’t hotwire your car if they are able to get in to the car via broken windows.

Have a cell backup for your alarm system. If your alarm is hooked up to a phone line, it can easily be disarmed by having the phone line cut. You can have additional home security by having a cell unit installed to the alarm system, which also won’t tip off the robber.

Arm the second floor of your home. Some robbers tend to go through the second floor of a home, which also tends to have more valuables. Have an alarm system in the master bedroom of the second floor.

Always check and double check your locks after any visitors leave the house. You never know who could try to break in after visiting your home.

Keeping your home safe doesn’t have to be stressful. These seven simple tips can keep you and your family feeling safe and secure in your home easily and inexpensively. For more tips, visit HomeSecuritech.com

Top 3 Tips To Surf The Web Anonymously

There are different reasons why one would prefer to surf the web anonymously. Now that many are using the web for malicious purposes, and that other sites are getting more difficult to access, the ability to hide your identity when using the Internet can be very important. But what are the best ways to surf the web without exposing your identity?

Understanding Anonymous Surfing?

When you surf the Internet, your IP address, location and other identification of your computer are obtained by the server. But most of the above information is masked when you do anonymous surfing. This then allows you to access a restricted website, and to browse the World Wide Web in private. However, the level of anonymity depends on the type of service you will use.

Anonymous proxy server – A proxy server is the system that connects you to a source. For instance, when you need to access a website or download a file, your request will be sent by the proxy server to the source of the said information. It is called anonymous proxy server because it will hide your identity from the source by showing a temporary IP address. To use a proxy server, you just have to go to the website that provides the service, and type in the URL of the site you want to visit anonymously. It is a pretty simple process, but is not 100% safe.

P2P services – These are most applicable if your purpose is to download and upload files anonymously. Peer to peer (P2P) networks consist of anonymous participants, which means that their identity is hidden from one another. These are sites that do not wish to be recognized as the sender or receiver of information. For a small fee, you can use a P2P-friendly site to hide your IP address and be able to share or receive files without being identified by the other servers.

Virtual private network (VPN) – VPN is a secured connection between registered users in a network. This allows you to send and receive information in private through the Internet. A VPN will not only hide your IP address but also use other methods to maintain your security. It encrypts transmitted information so that it is only readable to the intended recipient. A VPN can make it seem like you are from another location, which is very useful if you want to access Facebook in China for example. VPN is normally a paid service, unless you use your own VPN client.

Conclusion

Anonymous surfing has many benefits. But to ensure complete privacy, you have to carefully select the type of service you will use. If you use the Internet for transmitting sensitive information, then you will be better off with a paid service. Free services have limitations, and therefore your security is not guaranteed.
