Define declarative and imperative security.Security checks can be applied imperatively or declaratively. Declarative security is applied by associating attribute declarations that specify a security action with classes or methods. Imperative security is applied by calling the appropriate methods of a Permission object that represents the Principal (for role-based security) or system resource (for code access security).
What are the differences between declarative and imperative security.Declarative and imperative are the different syntax schemes used to implement security declarations in .NET Framework. In declarative security, attribute syntax is used. The security constraints are stored in the assembly at compile time. The disadvantage of declarative security is that there are tools which extract security requirements from the metadata in the assembly.
In imperative implementation, the attribute syntax is not used. It is implemented by writing the regular code to provide restrictions
