When a denial-of-service happens, the malicious programs often occupies too much computing resources. A defending schema proposed in this paper can use virtual machine monitor to detect such attack by adapting threshold of available resources. If the defending system assures existence of attack, it will live duplicates the operating system together with the tagged applications to reserved isolated...
Auditable file system is used to track the usage of the file system including the operations like read and write. Auditable file system keeps the trails of userspsila action and the trails are kept faithfully for future auditing.
