Otherwise, you are allowing attackers to repeatedly attack your application until they find a vulnerability that you haven't protected against.

All sections should be reviewed The most common web application security weakness is the failure to properly validate input from the client or environment.

Some documentation and references interchangeably use the various meanings, which is very confusing to all concerned.

This confusion directly causes continuing financial loss to the organization.

Note that you should proceed to validate the resulting numbers as well.

As you see, this is not only beneficial for security, but it also allows you to accept and use a wider range of valid user input.

int payee Lst Id = Parameter('payeelstid'); account From = Acct Number By Index(payee Lst Id); Not only is this easier to render in HTML, it makes validation and business rule validation trivial. To provide defense in depth and to prevent attack payloads from trust boundaries, such as backend hosts, which are probably incapable of handling arbitrary input data, business rule validation is to be performed (preferably in workflow or command patterns), even if it is known that the back end code performs business rule validation.

This is not to say that the entire set of business rules need be applied - it means that the fundamentals are performed to prevent unnecessary round trips to the backend and to prevent the backend from receiving most tampered data.This is a dangerous strategy, because the set of possible bad data is potentially infinite.Adopting this strategy means that you will have to maintain the list of "known bad" characters and patterns forever, and you will by definition have incomplete protection.Data from the client should never be trusted for the client has every possibility to tamper with the data.In many cases, Encoding has the potential to defuse attacks that rely on lack of input validation.Integrity checks must be included wherever data passes from a trusted to a less trusted boundary, such as from the application to the user's browser in a hidden field, or to a third party payment gateway, such as a transaction ID used internally upon return.
