How can you successfully configure a secure Web server?

Conventional security measures such as firewalls and SSL provide defense to some attacks but you should thoroughly validate your input and use parameterized stored procedures as a minimum defense. Suggest the various actions that must be taken to provide basic information security for the digital information, computers, and networks.

Explain the basic input validation approaches?

Design process is a step-by-step and repetitive procedure where software is simulated according to the requirements. Do you think that design process is required for better quality software. Please explain in detail.

 Digital signatures provide benefits by enabling the replacement of slow and expensive paper-based approval processes with fast, low-cost, and fully digital ones. Do you agree on this statement? Why and also explain some digital signature algorithms.

What is disposable crypto? Because of its facilitation of privacy, and the diminution of privacy attendant on its prohibition, cryptography is also of considerable interest to civil rights supporters. But there have been a lot of controversial legal issues surrounding cryptography. Please throw light on such legal issues.
