* 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.
Snort has the following features: * It detects threats, such as buffer overflows, stealth port scans, CGI attacks, SMB probes and NetBIOS queries, NMAP and other port scanners, well-known backdoors
