Beginners Guide – Secure Network

October 9th, 2009

Secure network is vitally important for most network systems. Whilst email viruses and denial-of-service attacks (DoS attack) may cause us headaches on our home systems, for businesses, these sorts of attacks can cripple a network for days – costing businesses hundreds of millions each year in lost revenue. Not to mention corporate legitimate to clients.

Creating secure network to prevent this type of malicious attack is usually of paramount importance for network administrators, and while most invest heavily in some forms of security measures there is often vulnerabilities inadvertently left exposed. As we always heards that security is as secure as the weakest link.

Firewalls are the best place to begin when you are trying to develop a secure network. A firewall can be implemented in either hardware or software, or most commonly a combination of both. Firewalls are used to prevent unauthorized users from accessing private networks connected to the Internet, especially local intranets. All traffic entering or leaving the intranet pass through the firewall, which examines each message and blocks those that do not meet the specified criteria. If the packet do not meet security criteria then the system will not allowed those packets entering network system.

Anti-virus software works in two ways. Firstly it acts similarly to a firewall by blocking anything that is identified in its database as possibly malicious (viruses, Trojans, spyware etc). Secondly Anti-virus software is used to detect, and remove existing malware on a network systems or workstation.

One of the most over-looked aspects of secure network is time synchronization. Network administrators either fail to realise the importance of synchronization between all devices on a network or the system simply don't work. Failing to synchronize a network is often a common security issue. Not only can malicious users take advantage of computers running at different times but if a network is struck by an attack, identifying and rectifying the problem can be near impossible if every device is running on a different time.

Even when a network administrator is aware of the importance of time synchronization they often make a common security mistake when attempting to synchronize their network. Instead of investing in a dedicated time server that receives a secure source of UTC (Coordinated Universal Time) externally from their network using atomic clock sources like GPS, some network administrators opt to use a shortcut and use a source of Internet time.

There are two major security issues in using the Internet as a time server. Firstly, to allow the time code through the network a UDP port (123) has to be left open in the firewall. This can be taken advantage of by malicious users who can use this open port as an entrance to the network system. Secondly, the inbuilt security measure used by the time protocol NTP, known as authentication, doesn't work across the Internet which means that NTP has no guarantee the time signal is coming from where it is supposed to.

To ensure that you have a secure network, isn't it time you invested in an external dedicated NTP time server?

Secure Wireless Network

Having the ability to go wireless in your home or at the office is a great feature to have. Not only is it the freedom to be mobile, but also leaving your house wired free, and not having to route cables through drilled walls, shows another area where wireless is too good to miss out on. The freedom to roam your house from room to room, or even sit under the palm tree of your garden on a hot sunny day, proves there’s no going back from wireless network. However, because of the nature of the technology, wireless has a number of security issues we must be aware of And you will learn how to secure wireless network.

A neighbour, hacker or someone just by your home can easily detect your wireless network signals and attempt to connect to your wireless access point. This is because wireless network systems uses radio frequency and data travels through the air, though they do not need physical access to your router. This is where the security concern comes from.

So let’s get to the point. How bad could it be not secure wireless network?

The common stressing points we hear everyday regarding wireless security is the ability that an evil doer can easily sniff data, coming and going to your wireless access point. Also they will have the ability to use your router to browse the web just as you do… using your bandwidth.

It doesn’t really sound that bad… Does it?

Well how about if your neighbours or anyone on the street outside your home were using your wireless access point and taking part in illegal downloads, visiting illegal websites and generally using the web for criminal activity. Who do you think would get the blame? When you have the FBI busting through your door, and you’re quick to think your children are not as innocent as they claim to be, it may be a mountain for you to climb out of at this point.

The illegal downloads and criminal activity that was occurring from the next house on, was all under your ID. They were using your access point which from the ISP point of view was coming from your home. This is what happened when you are not securing your wireless network.

To add to this, in a couple of months time when your bank statement arrives through the door showing you spent £3000 on a new TV, as well as purchasing a set of Golf clubs, it may just all be too late by then. A hacker could have easily sat outside your home and sniffed your bank details or any other confidential details you may have used when online, all from the comfort of their car or home.  All they need is a wireless laptop to do this, and sit within a range of your wireless network router, in other words somewhere outside your house!

Now this also goes for businesses with wireless access points as well and not just for home users. In fact it is so much more crucial for businesses because a hacker can break into their network via the access point, hacking into company confidential data!

Therefore secure wireless network today is crucial for all the reasons above. Identity theft today is on the rise, and hackers will go the distance looking for insecure wireless access points. For this reason you should take the time and ensure you have a secure wireless network.

Wireless Network Routers

October 4th, 2009

Wireless networks have become very popular in these day’s market with the continuing increase in technology. A major concern with wireless networks is in fact to secure wireless network. Securing wireless networks has become more and more important with the increase in the number of users of wireless networks. It is now simple for the average individual to set up a wireless network system at home or at the office. These network systems may be within the range of many other potential network intruders with the technology to detect and access the systems.

There are several things you can do towards securing wireless networks. It is common however for many to leave out these steps and just start using the network system. The little time it takes to use these security features is time well spent and can be considered to be great preventative measures in protecting your system. The trouble can be encountered if your network system is not secure can lead to much more expensive and time wastage. e.g data leakage, virus, trojan etc.

One of the first steps in securing wireless networks is the changing of the administrative password for the router. This is important as most default passwords are common standards such as password and can be easily broken into. This password protects your router from unauthorized access and can prevent the unauthorized changing of your settings. The next tip for securing your wireless network is not to broadcast the name of your network systems. The majority of wireless network routers do this and this makes life easier for clients as they can locate the network without having to know the name but this is also an easy way for intruders to detect your network. It is therefore advisable to turn off the service set identifier for your system. And you can limited users accessing your network by registering their devices so you can control who is accessing your network systems.

There are normally two encryption types for the wireless network systems. These are WEP and WPA encryptions. The WEP encryption is not as strong as the WPA system and this means that the WPA is the better choice. This system provides protection that is easier to use and that is harder to crack than the WEP system. The WPA system is now found built in to many operating systems and all modems for wireless systems. This is a great step towards securing wireless networks.

Another action towards securing wireless networks is the reduction of the wireless network routers transmitter power. This has the overall effect of a reduction in the power and range of your signal. It is very difficult to adjust the signal precisely so there is no leakage outside of the required range but with trial and error it is possible to determine approximately how far the signal is leaking and to make adjustments accordingly. This greatly minimizes the opportunity for outsiders to intrude on your network. The disabling of remote administration is also another action that can be taken towards the security of the network.

So, when you setup a wireless network routers, keep in mind who gonna access your wireless network, how to secure your wireless network and don't forget to change the password, setup encryption and registering who can access your wireless network router.

The Broad Categories of Computer Network systems

October 3rd, 2009

Talking about computer network systems could give a heart attack to such people. However, it is not as scary as it may sound. For some people, the computer itself could be a scary topic, considering the fact around how complicated the machine is.

Computer network systems could be understood by separating the two words in the term. A “computer” as we know is a complex machine that helps us to process information. “Network” refers to linking or connecting. Hence computer network would simply mean getting two or more computers connected. When we say the word “connected” in this reference, we mean that one computer could be accessed through the other. This connection can be done by using wire or wireless devices e.g wireless network.

Broadly speaking there are two ways of connecting two or more computers. The first one is called the wired network and the other one is called the wireless network. Both of these are huge subjects to study and understand. However, in layman's language it could be said that when two or more computers are connected through wires it's called the wired network. And when they are connected without the wires through wireless router, it is known as wireless network. As the wired networks are limited to the area wherein the wire web is installed, similarly the wireless has range limitations. For wireless network we should consider how many devices will access the network. The number of machines that are on a network would ensure the speed of the network. More machines in a network would mean a slow network.

The various computer network systems could be – Personal Area Network; Local Area Network; Campus Area Network; Metropolitan Area Network; Wide Area Network; Global Network and most importantly internet, intranet or the extranet. The names are given to the network depending upon the arena they have. Like for example the campus area would mean the machines that are in a given physically limited campus are connected through the computer networking. This could be wired or wireless networking.

Internet could be understood as a global network systems. Since Internet connected many network system all over the world. By using network system we can connected to other people in the other side of the planet.

How to Wireless Network

September 28th, 2009
How to wireless network is something I need to share for all of you. In these days, many people working on the move, wether they are marketing, sales or business owner. for those mobile users wireless device is the only option device they have to do their jobs while away from the office. Sometimes these professional bring their work at home too, so they need network systems of their own.For those who’s not familiar with IT think setup a network installation could be a daunting task as they don’t know where to start and what todo. So for people who don’t know anything about technology could start from making some checklist about their needs. First list all you need from network systems, such as printer sharing, file sharing, gamings for kids and even internet sharing. After your list complete look again to see what is important to your goals. Then you need to create another list of peripheral that you need to connect it to your wireless network.

Now based on the list you make we can look what kind of peripheral you have that compatibel with your network design. From here you can measure how much money you need to spend on building your wireless network. After you create your budget then you may look some brands that suits your needs and off course you need to consider about compatibiliy issue for your hardware since you need to grow your wireless network as you update your devices.

For wireless network installation you can follow instruction on manual that comes with your hardware just look on how to. Wireless network is the simplest network systems to set up by your own. But if you feel confused and need some advice, contacting a network installer professional is your only option as these professionals has the ability to run network installation and also can advice you to choose the best network you need within your budget.

Wireless network
From Wikipedia, the free encyclopedia
Wireless network refers to any type of computer network that is wireless, and is commonly associated with a telecommunications network whose interconnections between nodes is implemented without the use of wires.[1] Wireless telecommunications networks are generally implemented with some type of remote information transmission system that uses electromagnetic waves, such as radio waves, for the carrier and this implementation usually takes place at the physical level or “layer” of the network.
Types
Wireless PAN
Wireless Personal Area Network (WPAN) is a type of wireless network that interconnects devices within a relatively small area, generally within reach of a person. For example, Bluetooth provides a WPAN for interconnecting a headset to a laptop. ZigBee also supports WPAN applications.[3]
Wireless LAN
Wireless Local Area Network (WLAN) is a wireless alternative to a computer Local Area Network (LAN) that uses radio instead of wires to transmit data back and forth between computers in a small area such as a home, office, or school. Wireless LANs are standardized under the IEEE 802.11 series.

Since then, wireless networks have continued to develop and their uses have grown significantly. Cellular phones are part of huge wireless network systems. People use these phones daily to communicate with one another. Sending information overseas is possible through wireless network systems using satellites and other signals to communicate across the world.

Do You Need a Home Network Systems

Wireless gear is about the same price as is cabled network equipment; and a length of Cat 5 Ethernet cable costs no more than does an audio cable. Both wireless and cabled networks have gotten better. The equipment now available has better documentation which makes it easy even for the less than technically skilled to set up a home network. Everybody uses email now and is aware of a few networking terms (HTTP, ping, etc.).

Thousands of pages have been written about fraud and identity theft due to poor computer security, making people better informed about the issue. The biggest problem for many people is simply familiarizing themselves with the technical terms involved in networking; NICs, protocols and so on. So if you’re interested in building a home network, then get going and start connecting all of those computers in your home together. Learn more tips and information about ecommerce web hosting software here.

How to Build a Simple Home Network System

Many people have relatively uncomplicated needs for their home networks. You’re going to need Cat-5 (or Ethernet) cables for a wired network. If you plan to build a wireless network, you can skip the cables.

You’ll also need a switch or a router for all of these cables (or radio waves if it’s a wireless network) to connect to. A router is better and can handle internet connection sharing; it is almost a must for a home network. You’re also going to need Network Interface Cards (or NICs) in each computer, printer or any other device you want to be on the network. If you are building a wired network, you can use Ethernet equipment with 10MB or 100MB speeds. There is also Gigabit Ethernet, but this is prohibitively expensive for many building a home network.

On a home network, your IP addresses will look like 192.168.0.1 or 10.121.0.1.

If the router has the number 192.168.0.1, then computers and other device should be numbered 192.168.0.2, 192.168.0.3. Don’t assign the same address to two devices.

Save Money by Setting Up a Home Network System

A Network Interface Card (NIC) will help you accomplish this.

Installing a network card is as easy as using it. If you are using a wireless system, your network card and router must also be wireless. Today most new computers are equipped with network cards already. There are several manufactures of network card. *3 Com: Producing network cards for the enterprise market. They provide secure type network cards with encryption, remote management, and server features.

*Broadcom: This company’s network cards are usually not visible on retailers shelves because they are already installed in other companies products.

Vital Office Network System Backup Data Recovery

Today’s companies rely almost entirely on their office network system to retain important and irreplaceable data. What happens in the case of a system failure, virus or weather disaster, after which critical data is lost permanently? If the unthinkable happens, companies who have trusted their office network installation company to perform the necessary backup measures can rest assured that their files are able to be recovered after a disaster.

How Common Is System Failure?

The best way to make sure that your company does not have to deal with lost data after an employee, office network or natural disaster is to perform regular file backups.

Office network installation companies recommend backing up data at the end of every workday, as well as performing a full system restore at least once a month to make sure the backup system is working.
