All validation for security purposes must be carried out within the server side script and not thorough client side authentication - such as JavaScript - as it can easily be bypassed by the user disabling JavaScript in their browser.

When dealing with a numeric input, such as age, telephone number or credit/debit card number the value of the variable should be processed through a specially constructed function to ensure that the data only comprises of numeric characters (and possibly spaces). Similar functions can be constructed to handle other data types such as Dates, Integers and Floats. Alternatively, for some numeric fields such as integers or dates the input method could be through the use of a drop-down selection box. If the input is selected from a dropdown box it would be generated by the source code and no validation will be necessary.

When dealing with string inputs it may be necessary on some occasions to allow the use of specific meta-characters. As an example, the tick should be allowed to be used in the surname filed so names such as O’Conner are accepted. In this case it would be advisable to accept the name and replace the apostrophe with two apostrophes before running it through the query or entering it in the database.

When dealing with all user inputs through text boxes, it is important to restrict the length of the input. All textbox fields should be as short as possible and must be an appropriate length for the data to be entered. By keeping each field as short as possible, the number of characters that an attacker could use to launch a SQL injection is restricted.

One line of defence include the Restriction of Error Messages. Error messages are normally generated in HTML which an attacker will be able to view. The details of all error messages should be logged in database or file on the server and displayed through a dynamically produced error page.

For each query executed within the code of the application, the most limited access rights possible should be attributed to the query itself. As an example, the data from a username and password text box on a login page should be only used in a query configured with code that ensures ‘read only’ permissions are given. This will prevent the attacker from inserting data into the database from the text box.

Stored procedures are an advanced feature provided by various SQL servers. In addition to providing some protection from SQL injection the use of stored procedures also increases the performance of the website by allowing the web application to compile and run SQL statements in the server itself. When stored procedures are used a number of conditions must be met by the injected code to be effective; the malicious SQL must be in specified structured format, with the correct number of parameters to be successful. The structure and number of parameters can vary greatly upon depending upon programming decisions made by the web developer.

In order to test a web site against an attack it is not necessary to be an expert at SQL injection as there are several software based automated tools available - such as the Web Vulnerability Scanner by Acunetix and SOAtest by Parasoft - which can be used to systematically carry out a range of attacks against including SQL Injection. Automated testing should be carried out on a regular basis and after any major changes to the web-site or server.

SQL Injection attacks present a serious threat to the security of dynamic web-sites and it is essential that adequate countermeasures are taken to prevent such an attack from being successful. In theory, if meta-characters were handled 100 percent effectively the risk of this type of attack through web-browser forms would be eliminated. In reality - if this was the only line of defence - it would be extremely easy for a programming mistake to be made leaving the system vulnerable. The best approach is to take as many precautions as possible, this is known as the ‘defence in depth’ principle. A combination of security measures such as; validation, neutralising or meta-characters, restricting error messages and limiting access rights to the web server can be used to comprehensively protect a web base application against a SQL injection attack. This approach in conjunction with thorough testing as one of the final stages of web development, together with regular testing and security reviews should be sufficient to protect against this SQL injection.

Today, the need for consumers to locate and engage local service providers continues to grow. Surveys of consumers indicate that that their jobs require them to work longer hours (88%). Many (75%) said they take care of personal responsibilities while on the job and 36% say they do this daily. Most importantly, it takes an employee nearly two hours to take care of personal business on company time. Consumers are looking for alternate ways to get their personal business handled.

At the same time, small businesses continue to grow in the U.S. In 2002, there were approximately 22.9 million small businesses in the U.S. Of these, there was an estimated 550,100 new employer businesses, a 0.9 percent increase over the previous year.

As consumers and daily workers continue to lead busier and busier lives, they are looking for ways to streamline their opportunities. Some online services, such as Angieslist.com, yellowpages.com, kudzu.com, etc. have attempted to fulfill this need. However, among other shortcomings, these and other sites receive their fees either from the consumer or in the form of monthly or annual listing fees charged to the business itself.

As the number of small business service providers grows, these businesses are seeking a way to reach their customers more economically. For the small business owner it is fundamentally a marketing problem - how do they reach their customers in a manner that provides them the greatest return on investment of their marketing dollars.

The historical and traditional marketing channels (Radio, Newspaper, Magazines, Flyers, Internet, etc.) are so numerous that they represent a problem for a local service provider. The service provider cannot effectively engage all of them. Furthermore, customers are constantly surfing channels and are able to block content at will and thus are able to avoid exposure to marketing messages.

A further need of a local service provider is the ability to reach the exact demographic/geographic market they are targeting. Many marketing opportunities are too broad and hence very inefficient. Since it is too costly to use all marketing channels, the service provider must cherry pick the best options (or what turns out to be the least costly options) and usually experiences poor ROI as a result. A limited marketing budget is not effective in a local market since using traditional channels since the local service provider will have to pay for a larger market and waste ad dollars.

Therefore, most businesses start with a website. However, there’s an incredible mis-conception about having what I’d call an “effective” web presence. A lot of businesses have a web page but most think it ends there. They’re wrong! Heck, after they’ve spent the $500-$1000 (a reasonable looking site with no features) to have their website built (not mentioning maintenance costs for updating), paid the $300/year for hosting - not to mention trying to get a .com URL that matches their name (good luck for Joes Plumbing) - you haven’t even touched the tip of the iceberg in terms of cost to get your site noticed on the web. Without costly internet marketing campaigns that cost upwards of $15-$25k a month (for more competitive search terms it can be more costly than that) companies that have their own website quickly find out that it’s like having a billboard in the middle of the desert. Sure a business can do a little organic SEO (Search Engine Optimization), however there’s still a lot to learn about doing that well and it takes a long time to create meaningful results.

Enter online directories such as yellowpages.com, angieslist.com, yahoo local, kudzu.com and merchantcircle.com to name a few. However, the most popular online directories are charging businesses as much as $750 per year for little more than obscure placement on their site and a promise to land them on the first page of each search engine. Once they get your money, however, it seems they completely forget about your business and owners are left crossing their fingers - wondering if they’ll ever see new customers from the directory.

Those days are gone! As of today, subscription based online directories are slowly giving way to “pay-for-performance” based directories like an interesting newcomer to the online directory, ServiceOmni.com is positioning itself to be.

Pay for Performance is here! The new breed of PFP directories are not charging a penny for your business to list (see Craigslist success). Rather than pay up front, the premise is simple: list your business for free and If no one clicks on your site, you don’t get charged. Period! Another feature of these sites is they market on a larger scale for the businesses themselves. They drive new eyeballs to their site to find plumbers, dog walkers, auto detailers and more - and in the process, the smaller business has a better chance of being seen - and hired.

The bottom line is businesses now have a choice in online directories that don’t charge up front fees. The climate is changing for micro-businesses and its time for every business to have the opportunity to get more online exposure and only pay for customers that click on their information in the directory. These PFP directories are the wave of the future and small local businesses will be well served by this new online strategy to capture new customers.

Peer to Peer (P2P) file sharing is a sure way of getting your computer infected with spyware. You may
think you’re getting the latest Red Hot Chili Pepper song for free, but you may be getting a little something extra
you didn’t expect.

Browser vulnerabilities or unpatched security holes in Windows can let spyware in your system without you knowing. This is
especially true with Internet Explorer, many hackers target IE because it’s the most used browser, I would recommend using
Firefox instead, much more secure. If you were using a unsecured browser and you went to a bad website (porn sites are
famous for this) that took advantage of the security flaw you could get infected automatically without even clicking or downloading
anything. This is why it is so important to update Window’s and your web browser right away when there is an update.

Email is another way of getting infected with spyware or viruses. Never click on links or open attachments, even if it’s from your
Uncle in Mississippi. Often these programs will look in the address book and send everyone of them the same email.
So before you go clicking on that link or opening up that funny picture Aunt Milgrid sent you double check with them first.

So follow those easy things and you should stay out of trouble, and get yourself a good anti-spyware program in fact get
several because no one spyware program can detect every single spyware/adware.

Tyler Lang is a security enthusiast. Get more information on how to get rid of spyware and get some free security tools.

Step #1 Make a Plan

Before you start your web page you need to have a plan. You want to know the focus of your site and what kind of information you will put on your site, as well as how you want to design it. Having a plan and a strong sense of what you want to do will make finding a webhost and actually designing your site a lot easier.

Step #2 URL

You will need to register a URL if you want to make up your own, but this step will cost you a few dollars. Not much, but it

Fair enough indeed. All was well in my chaotic world when the next morning I received an email from eBay stating they had suspended this gentleman’s account due to the fact that they were unable to verify his contact information. Uh-Oh!

Warning number one…

I then received an email from O the day after that acknowledging that his account was suspended, but that it was by his own actions, and that he had called eBay and it was straightened out and the account was back. Furthermore, he registered that account the very day he did the buy it now…

It was, and is still suspended nearly a week later… Warning number two…

He further proceeds to tell me his shipper is in the UK and that the car would be going there.

Wow, I thought to myself. This car spent it’s entire existence in Mountain Home, Arkansas and Daleville, AL and now it’s going to London! Cool!

When I finished that thought came warning number three… Why would the man be in NY but have his shipper and the car be going to London? Especially a 1974 Cadillac?

The song “The wheels on the bus go ’round and ’round” echoed through my head as I finally got it.

My revelation was cemented when I received the following email yesterday:

This is to let you know that the payment has been sent to you via regular mail, It will be delivered to you soon. As soon as you receive it, take it to your bank and cash it immediately, deduct your fund and the balance should be sent to my shipper through W U Money Transfer:

Shipper’s Information:

First Name: Robin

Last Name: Wheelan

Address: 1 Canal Walk, SE26 5EG, London, United Kingdom

I am aware that you would be charged to have the money sent through w u, whatever that would amount to, is to be deducted from the balance of the funds after you must have deducted your fund.

After sending it through w u, a number will be given to you called CONTROL NUMBER (MTCN) send the control number to me through my mail. I will await you reply containing the MTCN number and the amount sent.

Thank you.

Friends, this is the old cashiers check scam. Someone abroad “buys” an item with the promise of a cashiers check. We all know those are good immediately, right? Guess again. The world has changed. The seller is instructed to immediately deposit or cash the check and wire the shipping charges via W U or some such similar venue. The banks will usually immediately cash a cashiers check, or hold it for just 1-2 days before cashing it. By the time the bank and the seller realize the check was worthless, the cash is long gone and the seller is actually responsible for the money the bank gave them.

Thankfully I smelled a rat, and I still have the car. The check, however, is in the mail on the way to me. I fully intend to take it to the bank… but I will not cash it nor deposit it. I intend to have the bank confirm the check is not real and then follow up with my complaint to the FBI’s Internet Complaint Department and we’ll see what happens from there.

But if I have anything to say about it, O will be caught and do some time. Highly unlikely, but I can sure try to take one scammer off the streets.

And that, you can take to the bank!
