Buffer overflow countermeasures

“

- Buffer overflow attacks are common, and therefore there exist relatively well-developed countermeasures against them. The first option is to use a programming language that supports automatic bounds checking of buffers. These languages include Java and Python. A better solution is architectural and to use a built in language specific library module that implements info validation in the form of safe buffer handling. To check if there are any missed opportunities for properly managing the buffers, it is recommended to use a code scanning tool to detect the presence of any buffer overflow vulnerabilities. Compilers can also alert the programmers when an unsafe function call is made. In more advance compilers can compile a program so that protection against buffer overflow attacks can automatically be compiled in with the program. Finally, your Operating System can also be written to make buffer overflow attacks more difficult to launch. For example, the Operating System can enforce…
