Write well thought out code. Learn about common bugs such as bad 'system()' placement or buffer overruns.Btw, on the topic of java! Has there been published any research upon buffert overruns in java? I assume the class String is more or less secure, but are there security concerns related to usage of e.g. arrays?Java automatically performs bound checking on arrays. For example, if you try and add more elements to an array than you should:
Agreed. The buffer overrun issue for Java is that the JVM is often a C program, and *it* may contain buffer overrun vulnerabilities that enable the attacker to write bytecode that exploits a buffer overrun in the JVM to obtain privilege.
