The countermeasures to a buffer overflow are as follows:
* Perform manual auditing of the code.
* Stack execution should be disabled.
* Take the support of the functions which are not the cause of the buffer overflow.
*
* Take compiler support. For example, Java automatically checks if an array index is within the proper bounds. Use compilers such as Java instead of C to avoid buffer overflow attacks. Use tools such as StackGuard and Immunix System to avoid buffer overflows.
Hackers’ motivations vary. For some, it’s economic. They earn a living through cyber crime. Some have a political or social agenda—their aim is to vandalize high-profile computers to make a
Every virus cannot be detected by a signature-based antivirus largely for the following reasons: * If an attacker has changed the signature of a virus, any signature-based antivirus will not
