(17)List down security requirements for grid computing?
Answer: The goal of grid computing is to provide secure grid service resources to legal users and therefore the security issue becomes an important consideration of grid computing.
(1)Single Sign On:
(1)Single Sign On:
- It is important mainly for systems where the resources are shared between multiple departments or organizations.
- Concept like Single Sign On where user authenticates once and able to use resources internally further authentication can be considered.
(2)Protection of Credentials:
- Security and protection of user authentication parameters like passwords, private keys, tokens etc. require to be considered.
(3)Interoperability with local security solutions:
- Security policy that provides inter-domain access mechanisms, access to local resources will typically be determined by a local security policy that is enforced by a local security mechanism.
(4)Exportability:
- The exportability issues mean that our security policy cannot directly or indirectly require the use of bulk encryption.
- Grid Computing require that the code be (a) exportable and (b) executable in different scenarios or systems.
(5)Support for secure group communication:
- Inter domain access requires, a common way of expressing the identity of a security principal such as an actual user or a resource. Hence, it is imperative to support for secure group communication.
(6)Support for multiple implementations:
- The grid computing security policy should not dictate a specific implementation technology.
- Further, it should be possible to implement the security policy with a range of security technologies, based on both public and shared key cryptography
