Server Protection through Dynamic Patching

Server Protection through Dynamic Patching
Recently, hackers has been developing fast propagating worms exploiting vulnerabilities that had just been disclosed by security experts. Those attacks particularly expose servers: this class of applications is constantly connected to the Internet and must meet uptime constraints. Hence they often run unprotected until the next scheduled update. In this paper, we propose a just-in-time protection for servers based on runtime injection of pre-made patches. The runtime injection permits to deal with uptime constraints and induces only a minimal overhead over the vulnerable code and only when a vulnerability is known to exist. The pre-made patches forbid exploitation of most common vulnerabilities (45% of attacks reported by Debian security in 2005 affecting C softwares) and allows continuous servicing.
