It is deniable that our works and lives are more convenient and easier when using wireless. We can work anywhere and that is why wireless networks are becoming so popular. Especially if you have broadband Internet access, a wireless router can give you instant communication with the world.

Imagine you are sitting by the pool and enjoying chatting through the Internet. Or lounging in the Jacuzzi listening to your MP3 collection is appealing to us all. Unfortunately, many, or even most, wireless units don’t come with security features already functioning. This may not seem like a big issue to someone who is simply setting up a home network, but there are a number of potential problems you should consider.

Identity theft seems to be the most serious problem. If your network is unsecured, the personal data on your wireless electronic equipment is also unsecured. The order you just placed for a book at Amazon may have given your contact and payment information to an unscrupulous hacker! Nearly every town in which “WiFi” is common will have “War Drivers” and “War Chalkers” at work. These are people who walk or drive around town with wireless equipment, searching for unsecured networks. The “Chalkers” then live up their name, marking curbs and other public items with chalk so that others can more easily find and exploit your network.

In fact, not all “War Drivers” are hackers, of course. Many just want to use your network for free, but the risk is high if you don’t learn how to protect yourself. You can usually find quite a bit of free information as to how to secure your network at the website of your router’s manufacturer, or by doing a search in a search engine for a phrase like “secure home wireless.”

In addition, there are also your neighbors who may find your network by accident and enjoy nosing into your activities and using your Internet access at will, slowing down your network speed in the process.

Even many businesses use cheap, home-use quality equipment for their company networks. With the poor security often found on small business networks, anyone with a basic knowledge of wireless can access sensitive company and customer data.

It is highly recommended that you hire service companies to secure your network for you, or else you will have to bear with a risk of being exploited. A search of your local yellow pages or an inquiry at your neighborhood computer store should yield professional help and get your private data private again.

People have more flexible time due to wireless network. Thanks to the invention of wireless. People can now work from home while taking care of their kids or doing house works. No more stress from traffic jam anymore. Is this great?

Well, there is something you should realize. Working from home while using a wireless local area network (WLAN) may lead to theft of sensitive information and hacker or virus infiltration unless proper measures are taken. As WLANs send information over radio waves, someone with a receiver in your area could be picking up the transmission, thus gaining access to your computer. They could load viruses on to your laptop which could be transferred to the company’s network when you go back to work.

Believe it or not! Up to 75 per cent of WLAN users do not have standard security features installed, while 20 per cent are left completely open as default configurations are not secured, but made for the users to have their network up and running ASAP. It is recommended that wireless router/access point setup be always done though a wired client.

You can setup your security by follow these steps:

1. Change default administrative password on wireless router/access point to a secured password.

2. Enable at least 128-bit WEP encryption on both card and access point. Change your WEP keys periodically. If equipment does not support at least 128-bit WEP encryption, consider replacing it. Although there are security issues with WEP, it represents minimum level of security, and it should be enabled.

3. Change the default SSID on your router/access point to a hard to guess name. Setup your computer device to connect to this SSID by default.

4. Setup router/access point not to broadcast the SSID. The same SSID needs to be setup on the client side manually. This feature may not be available on all equipment.

5. Block anonymous Internet requests or pings. On each computer having wireless network card, network connection properties should be configured to allow connection to Access Point Networks Only. Computer to Computer (peer to peer) Connection should not be allowed.

Enable MAC filtering. Deny association to wireless network for unspecified MAC addresses. Mac or Physical addresses are available through your computer device network connection setup and they are physically written on network cards. When adding new wireless cards / computer to the network, their MAC addresses should be registered with the router /access point. Network router should have firewall features enabled and demilitarized zone (DMZ) feature disabled.

All computers should have a properly configured personal firewall in addition to a hardware firewall. You should also update router/access point firmware when new versions become available. Locating router/access point away from strangers is also helpful so they cannot reset the router/access point to default settings. You can even try to locate router/access point in the middle of the building rather than near windows to limit signal coverage outside the building.

There is no guarantee of a full protection of your wireless network, but following these suggested tips can definitely lessen your risk of exposing to attackers aiming at insecure networks.

An intranet is basically a private web based network. It uses all of the technology of the internet but is safe and protected behind a firewall that keeps unauthorized personnel out. Companies have been using them for years as a method of streamlining their internal communications.

Because a web browser can run on any type of computer, the need to maintain multiple paper copies of documents that are constantly changing can be eliminated. Documents like training manuals, internal phone books, procedure manuals, benefits information, employee handbooks, requisition forms, etc. can be maintained as electronic documents and updated at almost no cost. The savings in paper and other material costs can be significant

But the most powerful aspect of an intranet is its ability to display information in the same format to every computer being used. That allows all of the different software and databases a company uses to be available to all employees without any special equipment or software being installed on their systems.

This universal availability of information is sparking an era of collaboration unlike anything ever seen before. The departmental barriers that exist in many companies are slowing breaking down because now colleagues can share information readily using the company intranet.

Options for implementing an intranet

There are a variety of options for setting up an intranet. They include building your own intranet technology, purchasing and installing third-party software, or purchasing access through an extranet ASP. Here is a quick summary of the advantages and disadvantages of each approach:

1. Building it yourself
Advantages: Complete control of user interface design; ability to customize level of functionality; integration into internal systems, and direct access to user activity.

Disadvantages: High up-front development cost; requires staff expertise in the development of extranets, commitment of internal staff for 6 months to a year for planning, execution, review and implementation; and an ongoing commitment of internal staff for internal and client support, hosting, maintenance and upgrades.

2. Purchasing/installing third-party software
Advantages: Proven track-record of packaged solution; ability to choose functions and to
customize user interface, more rapid implementation compared to building it yourself.

Disadvantages: High up-front purchase cost; commitment of internal staff for customization and implementation; on-going commitment of internal staff for internal and client support, hosting, maintenance and upgrades; and extensive internal and client training

3. Using a Service Provider (ASP)
Advantages: Proven track-record of the application; low cost of entry and predictable cost over time; virtually immediate implementation; no commitment of internal staff for internal support, hosting, or maintenance; and upgrades at no cost by extranet experts, and savings on internal server use.

Disadvantages: Less freedom in user interface design, and fixed functionality.

In the final analysis…
The approach you choose depends on how you work, the technical and financial resources at your disposal, and how rapidly you need to move forward.

Do you own or manage a computer consulting company? Are you having trouble growing your computer consulting company’s profits?

If so, then you must learn how to focus on your computer consulting firm’s profit and bottom line.

In this article, we’ll look at 7 profit secrets and strategies you can use in your computer consulting business, to ensure that you are able to balance your clients’ small business IT needs against your own computer consulting company’s profitability challenges.

Origins of the Problem

While focusing on your computer consulting profits may sound simple enough at first glance, this business-focused discipline often eludes many a computer consulting firm.

This usually happens because many computer consulting business owners fall in love the technology gadgetry, and get seduced by seemingly attractive reseller channel programs, at the expense of their business’ profit.

At the end of the day however, your computer consulting company is a business… not a charity and not a hobby. And your computer consulting company must be run like a business.

Profit Secret #1: Show motivation with your small business computer consulting clients.
To avoid being labeled as just another clueless geek, you need to position your computer consulting services to be more in line with those of a virtual CIO for hire. So always be on the look out for new ways to enhance your clients’ businesses… not just fix broken desktops and servers.

Profit Secret #2: Be dedicated to the task and relentless in your pursuit to improve the status quo.
Because it takes a lot of work to land the best computer consulting clients, you need to focus on lifetime customer value… not just one-shot-deal sales. So always remember that your proposed or recently implemented computer consulting technology solution isn’t a one-shot deal. This kind of long-term vision and planning requires tremendous staying power and perseverance… which often escapes many computer consulting business owners.

Profit Secret #3: Don’t be afraid to be creative with your client engagements.
Small business technology solutions often need to stay within relatively modest budgets. And your computer consulting solutions must work without the need for in-house IT staff. To satisfy these challenges, don’t be afraid to think outside of the box when appropriate.

Profit Secret #4: Evaluate how your clients’ systems, both paper- and computer-based, function today.
As part of your virtual CIO role, look at how these existing clients systems are meeting or not meeting present and future needs. Most of this work will be done during IT audits… another key computer consulting profit secret that can really help to separate you from the pack of mediocrity.

Profit Secret #5: Put yourself in your clients’ shoes and think about what THEIR clients need from them.
Yes, as a computer consulting business owner, you need to have good people skills and a certain degree of empathy for your clients’ business problems. But an even more advanced computer consulting business owner doesn’t just stop at understanding their clients’ business problems. The virtual CIO really digs in and learns about their clients’ customers’ business problems… one layer down on the value chain.

Profit Secret #6: Keep up with advances and new versions.
As virtual CIO for your computer consulting clients, your clients depend on your firm to advise them on what tools can better help their businesses grow. So while you can’t allow this R&D and training to consume and devour all of your scarce weekly schedule, you do need to stay a few steps ahead of your clients’ IT needs at all times.

Profit Secret #7: Summarize and share that information with your clients.
The essence of your R&D and training should focus on one major objective: will this new platform or tool add value to your computer consulting clients’ existing or future installations? And how you can best summarize this information, in layperson language that non-technical clients can understand?

The Bottom Line
Your computer consulting firm’s needs to be your client’s virtual IT department can often be at odds with your computer consulting firm’s need to be profitable. A big part of this problem happens because computer consulting business owners fall in love with technology, at the expense of their marketing and sales activities.

To make sure you don’t fall into this same strap, which can kill your computer consulting profits, don’t go overboard with your training and R&D activities. Be sure to keep business development activities in your weekly schedule… EVERY week. If you want to keep your computer consulting profits as healthy as possible, make sure that you’re proactive in your marketing and sales activities… dig the well for computer consulting profits BEFORE you’re thirsty.

Web and FTP Servers

Every network that has an internet connection is at risk of being compromised. Whilst there are several steps that you can take to secure your LAN, the only real solution is to close your LAN to incoming traffic, and restrict outgoing traffic

However some services such as web or FTP servers require incoming connections. If you require these services you will need to consider whether it is essential that these servers are part of the LAN, or whether they can be placed in a physically separate network known as a DMZ (or demilitarised zone if you prefer its proper name). Ideally all servers in the DMZ will be stand alone servers, with unique logons and passwords for each server. If you require a backup server for machines within the DMZ then you should acquire a dedicated machine and keep the backup solution separate from the LAN backup solution.

The DMZ will come directly off the firewall, which means that there are two routes in and out of the DMZ, traffic to and from the internet, and traffic to and from the LAN. Traffic between the DMZ and your LAN would be treated totally separately to traffic between your DMZ and the Internet. Incoming traffic from the internet would be routed directly to your DMZ.
Therefore if any hacker where to compromise a machine within the DMZ, then the only network they would have access to would be the DMZ. The hacker would have little or no access to the LAN. It would also be the case that any virus infection or other security compromise within the LAN would not be able to migrate to the DMZ.

In order for the DMZ to be effective, you will have to keep the traffic between the LAN and the DMZ to a minimum. In the majority of cases, the only traffic required between the LAN and the DMZ is FTP. If you do not have physical access to the servers, you will also need some sort of remote management protocol such as terminal services or VNC.

Database servers

If your web servers require access to a database server, then you will need to consider where to place your database. The most secure place to locate a database server is to create yet another physically separate network called the secure zone, and to place the database server there.
The Secure zone is also a physically separate network connected directly to the firewall. The Secure zone is by definition the most secure place on the network. The only access to or from the secure zone would be the database connection from the DMZ (and LAN if required).

Exceptions to the rule

The dilemma faced by network engineers is where to put the email server. It requires SMTP connection to the internet, yet it also requires domain access from the LAN. If you where to place this server in the DMZ, the domain traffic would compromise the integrity of the DMZ, making it simply an extension of the LAN. Therefore in our opinion, the only place you can put an email server is on the LAN and allow SMTP traffic into this server. However we would recommend against allowing any form of HTTP access into this server. If your users require access to their mail from outside the network, it would be far more secure to look at some form of VPN solution. (with the firewall handling the VPN connections. LAN based VPN servers allow the VPN traffic onto the network before it is authenticated, which is never a good thing.)

Do you own or manage a computer consulting company? Would you like to achieve greater small business success? If so, then get ready to learn why most computer consulting companies get IT (Information Technology) wrong and what you can do about IT.

The Problem: Why Most Computer Consulting Companies Get IT Wrong

Most owners of computer consulting companies make their jobs much harder than need be. Why? Because these computer consulting business owners fall in love with the technology… and view their small business clients as a distant second priority.

However, if you get this part of “IT” wrong, you will doom your computer consulting company to “clueless geek” status. It’s crucial that you understand one extremely important principle here: Recruiting and retaining small business clients is your #1 computer consulting priority. Keeping up with IT should never get in the way of the mission of your computer consulting company.

In other words, don’t get seduced by the hardware, operating systems or applications. Fall-in-love with the business opportunities surrounding how you solve your clients’ biggest business problems with your recommended IT solutions. That’s the real mission of a computer consulting company.

The Solution: Blend Computer Consulting and Virtual IT

To put this all in perspective with your computer consulting company, you need to understand and embrace the concept of virtual IT.

Virtual IT is what allows your computer consulting company to function as an extension of your small business clients’ companies. Your computer consulting company essentially becomes the outsourced IT department for your small business clients.

As owner or manager of a computer consulting company in this role, you will most likely become the de facto CIO (chief information officer), CTO (chief technology officer), or IT manager for your small business clients.

And just like any well-rounded internal IT department, your virtual IT computer consulting business will need to provide, or arrange for, a complete soup-to-nuts solution that includes services like help desk, desktop support, network administration, engineering, security, training, procurement, and asset management… because anything short of the complete virtual IT solution will leave valuable computer consulting money on the table.

The Bottom Line

Most computer consulting companies are making a huge mistake when it comes to their small business engagements… because these computer consulting business owners fall-in-love with the technology, at the expense of the business opportunities. In order for your computer consulting company to flourish, make sure that you understand the concept of virtual IT and build virtual IT into every major business decision for your computer consulting company.

Link Load Balancing evens out critical resources on data networks with unpredictable requests issued to a server. For example, a web site with heavy traffic may employ two, three or more servers in a link load balancing program. The link load balancing routines enable a network to “juggle” more traffic that otherwise possible If one server is overwhelmed, the link load balancing scheme forwards them to a different server with extra capacity.

Another aspect to link load balancing concerns the communications channels themselves. In this case the “juggling act” is meant to better distribute processing and communications demands more equitably across the network so that no single a computer is overwhelmed by the demand.

Link Load Balancing – Key Features & Benefits
First and foremost is “availability” – 24/7 Application Availability for complete IP Application access. Local and Global Service providers rely on redundancy and link load balancing between servers, WSD units and distributed sites for complete server continuity across global networks

Network Bottlenecks – Link Load Balancing
Network managers are constantly seeking new solutions for eliminating bottlenecks and latencies for the fastest performance of all networked applications and web-enabled transactions. The idea link load balancing technology combines both unlimited application scalability with flexible traffic distribution management of data centers and server farms.

Network Security – Link Load Balancing
Link load balancing is a key element in the overall network Intrusion Prevention effort. Expert Link Load Balancing guards the network against internal and external attacks such as viruses, worms, Trojans, anti-scanning and protocol anomalies. Above all hovers the ultimate link load balancing challenge and network threat – DOS – Denial of Service.

Remember the song, “Take a load off Annie” Just listening to it makes you feel nice and relaxed… For maximum performance and 100 percent uptime, networks use link load balancing to even out resource use throughout the network.

Top 3 Ways to Maximize Your Small Business Server Consulting Profits

Over the past 7 years, Microsoft Small Business Server (SBS) has gained traction as a widely-respected Small Business Server networking suite.

As a result, many small business computer consultants, systems integrators, and value-added resellers have jumped on-board the Microsoft Small Business Server bandwagon.

However, before you go ahead and bet YOUR company on Microsoft Small Business Server, consider the following three Small Business Server Business Tips… so you can maximize your Small Business Server consulting profits.

(1) Most small businesses in your area have never heard of Microsoft Small Business Server.

Although there may be hundreds, if not thousands, of small businesses in your area that would be excellent candidates for Microsoft Small Business Server, don’t make the ultra-common mistake of assuming that the typical non-technical small business owner even knows what Microsoft Small Business Server is.

If you want to maximize your consulting profits and avoid commodity price wars, you’re much better off leading off with a pitch for something that’s more universally recognized… such as getting rid of computer viruses, stopping SPAM, or preventing computer security breaches.

(2) Sell your small business prospects on YOUR company first.

The real money in Small Business Server is NOT in reselling the Microsoft Small Business Server software. The real money comes from selling the RELATIONSHIP with the small business. So your company essentially becomes your clients’ outsourced IT department.

Remember, no small business owner is going to wake up in the middle of the night, in a cold sweat, craving Small Business Server. However, small business owners DO constantly lose sleep over what will happen to their companies if their computer systems fail them. Become the solution to the more primal, survival instinct and you’ll get plenty of opportunities to sell Small Business Server, once you’ve established a solid client/consultant relationship.

(3) Microsoft doesn’t value computer consultants as much as they sometimes say.

Little known fact: the first version of Microsoft Small Business Server, planned in 1996 and released in 1997, was code-named “SAM”… because Microsoft’s goal was for Small Business Server to completely bypass their reseller channel and be sold at “Sam’s Club” warehouse clubs.

So the product team had the mandate to make the Small Business Server product SO simple that a non-technical small business end user could buy Small Business Server at the warehouse club and have the Small Business Server suite running in their office that same day.

Shortly after the first-version shipped, Microsoft realized that the most cost-effective way to reach small businesses with Small Business Server was through their reseller channel. And since then, Small Business Server resources have flowed toward the channel.

However, even today, you can often find 5-user versions of Microsoft Small Business Server in retail stores.

So the point: Microsoft isn’t putting all its Small Business Server “eggs” in one basket, so why should you?!? Which brings us back to points one and two: Small business owners aren’t actively shopping for a “Small Business Server”. So instead of “selling” Small Business Server per se, you’re much better off selling a small business on YOUR company, BEFORE you sell Microsoft Small Business Server.

The Bottom Line

In this article, we looked at three Small Business Server business tips that every computer consultant, systems integrator and value added reseller needs to be aware when selling Microsoft Small Business Server.

Buyer Beware – Ignorance can be a financial waste and a lot of hassals. Before you buy any wireless equipment, you need to be sure about what you’re doing. There’s nothing worse than having everything there and finding that it doesn’t work in your house, or with your computers, or over the distances you need. Here’s a handy checklist of the things that you really ought to do before you go out and spend any of your hard-earned cash on wireless networking equipment.

Interference Checks

While it won’t stop a wireless network from working altogether, interference in its frequency range can slow it down significantly, as well as reducing its range. If something is causing interference, the first thing you’ll know about it is when your connection stops working — unless you know what to look for.

There are two very common causes of wireless interference: wireless phones and microwave ovens. 2.4Ghz, the most common wireless networking frequency, is also a commonly-used wireless phone frequency. It is possible, though, to find phones that use other frequencies. Microwave ovens, on the other hand, operate at around 2.4Ghz by definition. It should be alright to have devices like these in your house, but certainly not in the same room as any computer that you plan to use a wireless connection with.

Wall Construction

Wireless can, in theory, pass through walls and other partitions easily. In practice, though, some walls are more solid than others, which means that they are more likely to block some of the signal. Note that it’s only your interior partitions that matter, not the exterior ones. This does, however, include your floors, if you want the connection to work between levels.

Wireless does well with partitions made from: drywall, plywood, other wood (including doors), glass.

Wireless has trouble with: brick, plaster, cement, metal, stone, double-glazed glass.

Basically, it’s all to do with how porous the materials are — ones that let more of other things through also let more of your wireless signal through.

If you have a wall made of one of the ‘bad’ materials, it’s not the end of the world. It just means that your wireless connection might have a slower speed or a shorter range. You may want to spend more than you otherwise would to get better equipment and overcome this problem.

Decide Your Budget.

You need to stand back, take a look at your needs, and decide how much you’re going to spend. Do you have long distances to cover? Do you want your connection to go through stone walls? Each factor will help you decide how much you should be looking to spend — remember that the more problems you have, the more power you will need. On the other hand, if you live in a small wooden house, you can probably just go for the cheapest thing you can find.

Read Reviews.

It’s well worth searching a site like amazon.com for wireless equipment, and taking a look at people’s reviews to see what the different brands out there are like, and what you can get for your money. It is always a very bad idea to buy something without getting a second, third and fourth opinion, especially if you’re buying it online. If you can, try to get to a computer shop and see some wireless networking equipment in action before you commit yourself.

Install and Update Windows XP.

Finally, your wireless life will really be improved if you have the latest version of Windows. Because wireless is such a new technology, it wasn’t really around in any significant way back when Windows 98, ME and 2000 were released, and support for them wasn’t built in to the system. You’ll have a lot more trouble getting wireless to work on systems like these than you would on Windows XP.

Even if you’ve got Windows XP, though, that doesn’t solve the problem entirely. Windows XP Service Pack 2 (an updated version of Windows XP) contains much easier-to-use tools for configuring and using wireless than the un-updated versions do. If you’ve been using your copy of Windows for a while without updating it, you should really make sure you’ve got all the latest updates from http://windowsupdate.microsoft.com before you go any further.
