Validating software applications
This included seminars, workshops and presentations for the US FDA, SFDA, KFDA, HSA, ISPE, PDA, PIC/S and several national health agencies. Ludwig Huber is a frequent presenter at IVT conferences and has been awarded as the ' Presenter of the Year' out of 170 speakers.This photo is from IVT's conference on Network Qualification with Ludwig Huber as plenary speaker. Huber has published several books related to validation and compliance, for example: Validation of Computerized Analytical and Networked Systems.
Otherwise, you are allowing attackers to repeatedly attack your application until they find a vulnerability that you haven't protected against.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.There are four strategies for validating data, and they should be used in this order: This strategy is also known as "whitelist" or "positive" validation.For feedback from attendees of seminars and for other information on Dr. George Smith, FDA's national Part11 expert, at a panel discussion with Ludwig Huber during an IVT conference Smith and Huber discussed and answered questions about computer system validation and e-records.To ensure that the application is robust against all forms of input data, whether obtained from the user, infrastructure, external entities or database systems. This weakness leads to almost all of the major vulnerabilities in applications, such as Interpreter Injection, locale/Unicode attacks, file system attacks and buffer overflows.In many cases, Encoding has the potential to defuse attacks that rely on lack of input validation.For example, if you use HTML entity encoding on user input before it is sent to a browser, it will prevent most XSS attacks.Business rules are known during design, and they influence implementation.However, there are bad, good and "best" approaches.This confusion directly causes continuing financial loss to the organization.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.
