Hosting Where are you going to host your site?

Options

Host in your own network

Hosting Provider: without a dedicated server

Hosting Provider: with a dedicated server



Hosting In your own network

Pluses You have 100% control Updating and making changes are very easy

Minuses Needs a high bandwidth leased line (>128Kbps) Your ISP’s performance effects your users



Hosting Hosting Provider: without a Dedicated Server

Pluses Cheaper than hosting in your own network Good for small retail store sites with less transactions. Most providers have high bandwidth networks

Minuses Limited control. (eg: limited disc capacity, database support etc) Has to use the update methods they provide (eg: FTP) Provider preferred payment gateways.

Eg: www.verio.com (price ranges from $29 - $175) www.activeservers.com (price ranges from $50 - $200)



Hosting Hosting Provider: with a Dedicated Server

Pluses More control/management power on your server Changes, updates can be done according to your preference (eg: use of tools such as

pcANYWHERE, FTP etc) Most providers have high bandwidth networks

Minuses Expensive than non-dedicated hosting Hardware updates, backup etc will be charged

Eg: www.verio.com (price ranges from $395 - $1700) www.globix.com (price ranges from $695 - $2300)



Hosting- Security

Security For an e-Commerce site (specially with credit card

transactions), strong security is a must.



Hosting- Security

What are security holes Spoofing

Creating bogus sites which would deceive customers and thereby collect CC numbers.

Unauthorized disclosureHackers can intercept transmissions and obtain sensitive data (like CC numbers)

Data AlterationHackers can intercept, alter or even re reroute sensitive data.



Hosting- Security

How to Secure your Site? Install a Secure Server ID

How to obtain one? You have to apply from a trusted Certification

Authority (CA).

eg: www.verisign.com



Hosting- Security

How does a Server ID protect your site? Authenticates your site Encrypts all messages to and from the client

browser with SSL (Secure Socket Layer). This eliminates hackers reading the content.

Checks Message integrity.



Hosting- Security What's Required to obtain a Server ID?

Details about your organization D-U-N-S numbers (Dun and Bradstreet number) Certificate Signing Request (CSR) generated from

“Key Manager” IIS. Price

US$ 349 for 40 bit encryption US$ 895 for 128 bit encryption



Hosting- Security Installing the Server ID



Credit Card Processing

Main Steps. Authorization

Credit Card Processing

Methods of Web based CC Processing Offsite Payment Processors Component Based (with SDK’s)



Credit Card Processing Offsite Payment Systems

Here your credit card processing is done in a separate site. Which means at the point of payment, the user will be transferred from your site to the processors site.E.g.:www.PayPal.com, www.CCBill.com, www.iBill.com

Pluses Very easy to setup. Near “Zero” Coding Cheaper No Merchant Accounts needed. No secure server needed

Minuses Less control over transactions Look of your site will be lost in the payment step. Data entry duplication



Credit Card Processing Component Based

Here the payment gateway that you select will give the necessary server software (SDK) to communicate with the payment gateway. E.g.:www.CyberCash.com, www.SurePay.com

Pluses You have 100% control over transactions. User never goes out of your site in the payment process.

Minuses Needs a Merchant Account Needs Secure Server Needs more programming to set up communication with payment

gateway.

Mind-Reading Your Users

E-Commerce sites can log each move of a user. Its like having surveillance cameras everywhere in your store/office.

Track click paths What the user bought last time Where most users abandon your site Pages most users visit …. and tons of statistics about user behavior



Mind Reading Your Users

How can we use these data?

Personalize the site for the user Use “Cookies” to keep track of user visits Help the user in selecting Find places where your site fails and correct them. Stream line the site for the customers!!!



What we looked at …

Forms of e-Commerce. Microsoft’s range of servers and development

tools to develop and manage e-Commerce sites Hosting methods Securing your site with VeriSign Server ID Credit Card Processing Customizing your site with user behavior

statistics.
