Internet Service Providers to Change IP
by admin on Jan.28, 2012, under Security
Most Internet service providers (ISP) have made it part of their package to change IP. The Internet Protocol address, or the IP address, of a computer is that computer’s unique address in the online network. And in offering online security and privacy to its customers, the Internet service providers have gone on to use dynamic IPs instead of static IPs.
In your quest to choose an Internet service provider for your home computer or your office connection, you should consider the type of IP address that the service is providing. The recommended one of the two would by the dynamic IPs.
Let us first be familiar with the two types of IP addresses. The first is the static IP, which is assigned to the computer by the network. This address does not change whenever we connect to the Internet. The settings of your computer will remain the same and intact, allowing the computer to connect to the Internet and get data faster.
In contrast to the static IP address, the dynamic IP address is allocated by a router, and it uses DHCP, or Dynamic Host Configuration Protocol. The DHCP allows for the allocation of an IP address to your computer when you connect to the Internet. It picks up the allocated IP address from a pool of IP addresses available, and every time you connect to the Internet you will have a different IP address. Most Internet service providers use this for their customers. Not all, though, and we have to know what kind of address system the Internet service providers are running on.
As stated above, dynamic IPs are the preferred one of the two. They were made to change and go to another computer user, giving another user that IP address. Your IP will also will be a different one the next time you log onto the Internet. It’s a change “wheel” going on with dynamic IPs, and it is an advantage for us. The change in IP leads to a hack-proof system, as it will give a hacker or any malicious attacker a hard time to get to your data when your address is always changing.
But, of course, static address is also commonly used. Many businesses prefer to run a static IP because of the data that they want to give to the customers they have visiting their website. There’s also the issue of the business employees working in various locations but needing to connect to the company’s data. This would require static IP. Among businesses and companies, the static IP running system is much more in demand.
When we are browsing the Internet on our personal time and our personal computer, though, changing or hiding our IP address is important. Our personal files and accounts may be at risk if we have a real and static IP as our online address. This is not the right precaution if we want to protect our online privacy. For us personal users, it is better to choose an Internet service provider with a system to change IP.

Bypass your School and Work Filters with an Anonymous Proxy Server
by admin on Jan.18, 2012, under Internet And Businesses Online
With the proliferation of the Internet, many websites promote themselves by sending you spam junk mails, advertisings and even embed spyware that is difficult to remove onto your computer. These things not only keep track of your personal information, but also enable hackers and crackers to infiltrate your system. Anonymous proxy servers act as a wall between your data and the Internet, whereby providing security to your system and data. There are however, other reasons to use an anonymous proxy server.
If your work or school has any type of filtering in place to prevent people from visiting certain websites, an anonymous proxy server is a great way to get around such restrictions. Anonymous proxy servers work by acting as a “middle man”; they download the requested pages to their proxy server and in turn you download the page, all images and other such objects from the proxy server to your browser, thus bypassing any filters or annoying firewalls. Not only is this a viable alternative for students to bypass their school’s filter to access such popular student sites such as Myspace or Xanga but can be used if your workplace has strict limitations on which websites you can access. Most anonymous proxy bypass servers use one of two program, PHProxy or CGIProxy, both of which are excellent proxy software packages.
After you have discovered the benefits of using anonymous proxy servers, you will probably want to try it out. There are numerous free proxy services out there, one of the most popular is SpySurfing ( http://www.spysurfing.com/ ) and is a really fast proxy server that is popular among both students look to bypass their school filters and adults looking to bypass their work place firewalls.

I Need A Proxy, Everybody Wants A Proxy!
by admin on Jan.14, 2012, under Internet And Businesses Online
I guess I’m not going to be very popular after publishing this article, but this is really a big problem and one that needs to be addressed very quickly before it grows into another digital snowball like spam and malware. IT departments spend a lot of time and money on network security. Restrictions are put into place, not only to protect corporate data, but also for the safety of everyone working on the corporate network. However, network restrictions are not only for the corporate world, these restrictions are also present at schools and even in our homes. But what is the use of protecting your data and privacy if you constantly have to deal with cyber rats eating their way through your defences from the inside?
A proxy is often blocked as soon as the network administrator becomes aware of the fact that it is used to gain unauthorised access to websites and other networks. That’s the reason why people are constantly in search of brand new proxies and what scares me the most, is the rate at which these new proxies become available, it is so bad you can even regard it as another form of spam. The sad reality however, is that the people who use these proxies, either do not know a thing about PC security, or they don’t give a damn about it. Browsing restricted sites via an illegal proxy exposes your computer to malware and hackers, putting the whole network at risk. Confidential and sensitive corporate information can easily be leaked and the privacy of every employee using the corporate network could be compromised due to the selfish acts of employees who can’t walk between the lines. So you are not only putting your colleagues in a tight spot, your compromising your own security as well.
The most popular reason for a proxy is to gain access to social networking sites like MySpace, Facebook, Orkut or Twitter. Social networking sites are time and money wasters in terms of productivity, bandwidth and company resources. Instead of doing their jobs, people waste hours and hours of productivity during the day, by hanging out on social community sites. To add insult to injury, they don’t use their own bandwidth to chill on these sites, they use company bandwidth, company computers and company printers to do what they should be doing after work. Kids browse these social communities instead of attending to their schoolwork, wasting their parents’s money, or the money of the taxpayer if the government funds the school. Speaking of the government, what about government workers? Instead of delivering the services we pay for, they browse MySpace, Facebook, Orkut or Twitter with our tax money. (Some governments do not even have any network security to speak of, so they can access any site without the use of a proxy).
Don’t get me wrong, I’m not against the use of social networking sites, but there is a time and place for everything and social networking sites do not have a place at the office or at school (unless you are the PR manager of the company maintaining the company profile on MySpace). Before everyone starts to call me a party pooper, accusing me of taking the fun out of the office, think about this: If everyone spent more time on their job and less time on social networking sites during working hours, we will get a lot more work done and will therefore have plenty of time to hang out with friends and family on our favourite social networking sites. Don’t be mad at your boss for limiting your Internet access, the fact that you are using a proxy to bypass Internet filters and other limitations imposed by your employer, already tells me that you can’t use the Internet responsibly. If you really need to use these sites, visit them after work or after school and if you don’t have a computer at home, use a friend’s computer or visit an Internet café. It has to be mentioned though, that 3rd party proxies are not only used to access social networking sites, but they are also popular for **** surfing and the downloading of pirated software, music and movies. These sites are far worse than social networking sites, because they do not only waste valuable man-hours, they are often loaded with nasty malware, a direct threat to the safety of everyone working on the network.
The bottom line is, companies invest a lot in computer security, computer labs at schools do their best to keep their networks safe and clean and parents invest in parental control software to keep their young ones from accessing harmful content on the Web. Still you get people who want to break down all these barriers, ignoring the damage they cause and the risks they create during this process. Bypassing the parental control software on the family computer can easily lead to a prohibited site where a sneaky rootkit finds its way into your system. It may log a credit card number here and a password there and before your folks know what’s going on, they could be staring bankruptcy in the face. The same can happen at work or at school, your infected PC can cause a lot of problems for other people using the same network. Do you want something like this on your conscience? Proxies may have their uses, but they should not be used to cross digital borders illegally. If you are not allowed to visit a specific site at work or at school, then there’s most likely a pretty good reason why you shouldn’t visit it. If you choose to visit prohibited sites without proper authorisation, you risk loosing your job, getting suspended or even harsher network restrictions may be implemented. Think about it, is it really worth all that?
People are so touchy about this subject that when they ask for new proxies in forums or Q&A communities, they often warn you in advance not to ***** about why they shouldn’t be using one. So next time when you run across someone asking for a proxy to bypass firewalls and Internet filters, don’t waste your time explaining why they shouldn’t be using one, don’t expose yourself to insults and swearing, just refer them to this article.

How Can I Secure My Wireless Network?
by admin on Jan.10, 2012, under Security
Wireless Internet connections are certainly convenient, especially in terms of reducing the clutter of all those wires.
They are also convenient for other reasons too but you may not like those.
Hackers love wireless networks – they can break into many with relative ease and they don’t even need to be in your home to do so – they can access them from the street outside with a wireless laptop.
Fortunately, however, it isn’t difficult to protect yourself.
Wireless networks can be particularly vulnerable to digital intruders which means any sensitive or private data on them can be at risk.
However, you can protect yourself in many ways, including using WEP or WPA encryption, both of which require users to enter a password before they are allowed to access your wireless network.
Here are some additional tips on how you can protect your wireless network -
* Reduce the broadcasting range of your network – doing so can keep nosy neighbours from intruding on your connection. You can do this by moving your wireless router away from external wall in your home and by decreasing it’s power settings.
* Change your router’s default password – hackers and crackers know what they are!
* Disable SSID broadcasting as most wireless routers broadcast the names of the network which could aid a hacker.
* Disable your wireless connection when you are not using it.
* Always use a strong firewall that will go a long way to protecting your computer from outside interferance.
* Think twice before sharing files over your home network as other users may not be as security conscious as you.
* When connecting to a network be sure to connect to your own and not any others that may be in range – who knows what security risks other people’s networks may pose to your own?

What is a Virtual Private Network (VPN)?
by admin on Jan.04, 2012, under Internet And Businesses Online
A virtual private network (VPN) can either be a remote access or site-to-site network – whatever the case, you’ll need specific software and hardware to build a VPN. For instance, you may need a desktop software client for each remote user, dedicated hardware (a concentrator or secure PIX firewall), a dedicated server for dial-up, a network access server for use by a service provider for remote users to access VPN, and a network and policy management center.
There is no single way to put together a VPN, which is why most companies come up with a solution for their own needs. Most VPNs, however, make use of Cisco VPN technology simply because it is the most widely used equipment for networking in the world.
So what are some of the hardware components you will need, in addition to VPN software? One component is called a concentrator. This piece of equipment is good for remote access, with encryption and authentication techniques that are quite advanced. With high availability, performance, and scalability, this piece of hardware also includes SEP modules that let you increase capacity and throughput. VPN concentrators sold work in small business situations, as well as in larger businesses, with up to 10,000 remote users.
A VPN optimized router is used for scalability, routing, security, and quality of service. This piece of equipment is usually based on the Cisco IOS VPN software – you can find routers for many different networking needs. Small offices make use of them, as well as larger businesses.
If you’re setting up a virtual private network, you’re also going to need a secure PIX firewall. A PIX (private Internet exchange) firewall comes with dynamic network address translation, proxy server, packet filtration, firewall and VPN capabilities all in one. A Cisco VPN always makes use of this type of hardware to set up an SSL VPN, although a PIX usually doesn’t use the Cisco IOS software, but an efficient operating system that is designed to perform exceptionally well.
VPNs are used to connect offices and workstations together over a private network for various purposes. The type of software you implement depends on the type of network you are building. Most Cisco networks use a Cisco VPN client and software, for compatibility reasons. No matter what VPN client you use, an SSL should be set up to work as efficiently as possible, and have the proper security measures put in place to protect the dissemination of data.
Things have really changed in the past few years, with companies being forced to deal with worldwide markets and offices in different locations across the globe. With segments of modern businesses often spread out across different locations, the most important technology is the virtual private network. VPNs allow companies to maintain internal communications that are fast, safe, and reliable. Modern VPN technology and equipment give businesses the opportunity to do this inexpensively. Without the reliable communication capabilities of a VPN, companies wouldn’t run so well.
