Network-Security-Policy Analysis
Computer network security is the first line of defence to accomplish information assurance. The computer network is at risk without a well-designed and flawless implemented network security policy. The main problem is that network administrators are not able to verify the network security policy. Although further research has been carried out, it mainly concerns small specific parts of the over...
متن کاملNetwork Security Policy Verification
We present a unified theory for verifying network security policies. A security policy is represented as directed graph. To check high-level security goals, security invariants over the policy are expressed. We cover monotonic security invariants, i.e. prohibiting more does not harm security. We provide the following contributions for the security invariant theory. (i) Secure auto-completion of...
متن کاملTransparent Network Security Policy Enforcement
Recent work in the area of network security, such as IPsec, provides mechanisms for securing the traÆc between any two interconnected hosts. However, it is not always possible, economical, or even practical from an administration and operational point of view to upgrade the software and con guration of all the nodes in a network to support such security protocols. One apparent solution to this ...
متن کاملNetwork Security: Vulnerabilities and Disclosure Policy
Software security is a major concern for vendors, consumers, and regulators since attackers that exploit vulnerabilities can cause substantial damages. When vulnerabilities are discovered after the software has been sold to consumers, the firms face a dilemma. A policy of disclosing vulnerabilities and issuing updates protects only the consumers who install updates, while the disclosure itself ...
متن کاملAutomatic Management of Network Security Policy
This paper describes work in our project funded by DARPA Dynamic Coalitions program to design, develop, and demonstrate a system for automatically managing security policies in dynamic networks.. Specifically, we aim to reduce human involvement in network management by building a practical network reconfiguration system so that simple security policies stated as positive and negative invariants...
