By Christoph Kern, Anita Kesavan, Neil Daswani

Foundations of defense: What each Programmer must Know teaches new and present software program execs state of the art software program protection layout ideas, method, and urban programming strategies they should construct safe software program platforms. as soon as you're enabled with the concepts lined during this publication, you can begin to relieve a few of the inherent vulnerabilities that make today's software program so liable to assault. The ebook makes use of internet servers and internet purposes as working examples through the book.

For the earlier few years, the net has had a "wild, wild west" taste to it. bank card numbers are stolen in great numbers. advertisement websites were close down by way of web worms. terrible privateness practices come to gentle and reason nice embarrassment to the companies in the back of them. some of these security-related matters give a contribution not less than to an absence of belief and lack of goodwill. usually there's a financial rate to boot, as businesses scramble to wash up the mess once they get spotlighted by way of bad protection practices.

It takes time to construct belief with clients, and belief is difficult to win again. safeguard vulnerabilities get within the approach of that belief. Foundations of defense: What each Programmer must Know is helping you deal with possibility as a result of insecure code and construct belief with clients through displaying easy methods to write code to avoid, notice, and include attacks.

The CFO should have the ability to transfer money from the company account to other accounts because the company may have certain financial commitments to creditors, vendors, or investors, and part of the CFO’s job may involve satisfying those commitments. Yet, the CFO could abuse that capability. Suppose the CFO, after logging into the system, decides to transfer some money from the company’s bank account to her own personal account, and then leave the country. When the missing funds are discovered, the system log can help you ascertain whether or not it was the CFO who abused her privileges.

Web browsers download and interpret data from web sites on the Internet. Sometimes web browsers do not interpret data in a robust fashion, and can be directed to download data from malicious web sites. A malicious web site can make available a file that exploits a vulnerability in web browser code that can give the attacker control of the machine that the web browser is running on. As a result of poor coding, web browser code needs to be regularly “patched” to eliminate such vulnerabilities, such as buffer overflows (as discussed in Chapter 6).

You need to ensure that no user can modify timestamps recorded in the log. The operating system, together with all the other computers on the network, must be in agreement on the current time. Otherwise, an attacker can log into a computer whose clock is ahead or behind the real time to cause confusion about when certain actions actually occurred. A protocol such as Network Time Protocol (NTP) can be used to keep the clocks of multiple computers synchronized. One problem with many of today’s systems is that logging facilities do not have secure timestamping and integrity checking facilities.
