Well, when I first thought of posting about this topic, a friend of mine suggested..

“Celia, forget about security. Once you put your application on the web, no matter what you do, it is always vulnerable.”

Another one said, “Gosh! Remember that we are from the service industry. Lets not overdo on that security aspect. The client will take care of it when he deploys it. Also, remember, we can do only what they ask for.. ”

As I pondered about this, I was wondering how I could strike a balance between these two people. Agreed, security is an ongoing thing. It seems like a race between the hackers and the crackers.. Today, we find a vulnerability and fix it. Tomorrow, there comes another issue.

Likewise, clients come in all flavors. There are some who really know a lot about what they want. These people are a delight to work with as their requirements are very clear. Also, they are quick to understand and know that building efficient security applications do take some royal effort. And there are some who think that application development shouldn’t take more than a week. There was this manager who once asked me, “After all, its just adding, editing, deleting and viewing. You are not doing rocket science. Why is it taking more time?”.

Yeah.. I agree to it. It would just take me one single query on the database to let an administrator login to a system. But it would take me atleast 10 other policy checks to prevent other users from manipulating this query. Wouldn’t this take some solid effort?

I hope people are atleast nodding a little now. Let me say one thing now. Even popular websites like gmail, facebook, youtube and msn have vulnerabilities. So, its not just because of a poor programmer’s pathetic code. Even experienced experts find it difficult to take care of all vulnerability issues when all their attention is focused on business logic.

In this case, what can be done? First thing:

Client: Client has to know that building secure web application takes some time. And some real effort.

Developer: The programmer needs to know how to secure their code and need to follow some security standard.

PM: The one who takes the real pressure. Needs to coordinate between the above two.

Security Consultant: The one who tells us what we already know ๐Ÿ™‚ .. well, jokes apart.. This is the person who makes our lives simpler. Who tells us what needs to be done to make our code secure and who reviews it before the app gets deployed in the production environment.

Now, just like how we have a separate team for application design, BI development and testing, we do need a separate group of security experts who concentrate just on the security aspect of the application. How a security expert will add value to the application, will be discussed in PART 2 of this article… ๐Ÿ™‚
