It is well known that virtual private network (VPN) and intrusion prevention system (IPS) are all important network security schemes. Traditionally, both VPN and IPS need a clear network margin. However, now the rapid proliferation of wireless networks and mobile computing applications has changed the landscape of network security. It is a noteworthy problem how to display wireless IPS (WIPS). Because...
Traditional static RBAC have not could satisfy the open dynamic information environment. Dynamic RBAC is researched more and more. In this paper, the dynamic of RBAC will be considered from a new perspective. A novel FRBAC (flexible role-based access control) model is discussed and analyzed. By bringing forward the concepts of role skeleton and role instance, a role can grow along with environment...
Now more and more organizations connect to the Internet, accepting the risks along with the benefits. In order to provide sufficient protection against increasingly sophisticated cyber-attacks, survivability technology is explored. For a terminal user, it is very important to construct a survivable workstation. A fine survivable workstation should sense multiple environment factors. To address this...
Traditionally access control models focus on access decisions by the static attributes such as identities, group names, memberships, and so on. Some dynamic outside environment factors are ignored. In this paper, we introduce the EAAC model which extends traditional RBAC to include the notion of both environments and behaviors by introducing a new conception that embodies the dynamic environmental...
