System.Security.Policy Namespace

Contains code groups, membership conditions, and evidence. These three types of classes are used to create the rules applied by the common language runtime security policy system. Evidence classes are the input to security policy and membership conditions are the switches; together these create policy statements and determine the granted permission set. Policy levels and code groups are the structure of the policy hierarchy. Code groups are the encapsulation of a rule and are arranged hierarchically in a policy level.

Classes

AllMembershipCondition	Represents a membership condition that matches all code. This class cannot be inherited.
ApplicationDirectory	Provides the application directory as evidence for policy evaluation. This class cannot be inherited.
ApplicationDirectoryMembershipCondition	Determines whether an assembly belongs to a code group by testing its application directory. This class cannot be inherited.
ApplicationTrust	Encapsulates security decisions about an application. This class cannot be inherited.
ApplicationTrustCollection	Represents a collection of ApplicationTrust objects. This class cannot be inherited.
ApplicationTrustEnumerator	Represents the enumerator for ApplicationTrust objects in the ApplicationTrustCollection collection.
CodeConnectAccess	Specifies the network resource access that is granted to code.
CodeGroup	Represents the abstract base class from which all implementations of code groups must derive.
Evidence	Defines the set of information that constitutes input to security policy decisions. This class cannot be inherited.
EvidenceBase	Provides a base class from which all objects to be used as evidence must derive.
FileCodeGroup	Grants permission to manipulate files located in the code assemblies to code assemblies that match the membership condition. This class cannot be inherited.
FirstMatchCodeGroup	Allows security policy to be defined by the union of the policy statement of a code group and that of the first child code group that matches. This class cannot be inherited.
GacInstalled	Confirms that a code assembly originates in the global assembly cache (GAC) as evidence for policy evaluation. This class cannot be inherited.
GacMembershipCondition	Determines whether an assembly belongs to a code group by testing its global assembly cache membership. This class cannot be inherited.
Hash	Provides evidence about the hash value for an assembly. This class cannot be inherited.
HashMembershipCondition	Determines whether an assembly belongs to a code group by testing its hash value. This class cannot be inherited.
NetCodeGroup	Grants Web permission to the site from which the assembly was downloaded. This class cannot be inherited.
PermissionRequestEvidence	Defines evidence that represents permission requests. This class cannot be inherited.
PolicyException	The exception that is thrown when policy forbids code to run.
PolicyLevel	Represents the security policy levels for the common language runtime. This class cannot be inherited.
PolicyStatement	Represents the statement of a CodeGroup describing the permissions and other information that apply to code with a particular set of evidence. This class cannot be inherited.
Publisher	Provides the Authenticode X.509v3 digital signature of a code assembly as evidence for policy evaluation. This class cannot be inherited.
PublisherMembershipCondition	Determines whether an assembly belongs to a code group by testing its software publisher's Authenticode X.509v3 certificate. This class cannot be inherited.
Site	Provides the Web site from which a code assembly originates as evidence for policy evaluation. This class cannot be inherited.
SiteMembershipCondition	Determines whether an assembly belongs to a code group by testing the site from which it originated. This class cannot be inherited.
StrongName	Provides the strong name of a code assembly as evidence for policy evaluation. This class cannot be inherited.
StrongNameMembershipCondition	Determines whether an assembly belongs to a code group by testing its strong name. This class cannot be inherited.
TrustManagerContext	Represents the context for the trust manager to consider when making the decision to run an application, and when setting up the security on a new AppDomain in which to run an application.
UnionCodeGroup	Represents a code group whose policy statement is the union of the current code group's policy statement and the policy statement of all its matching child code groups. This class cannot be inherited.
Url	Provides the URL from which a code assembly originates as evidence for policy evaluation. This class cannot be inherited.
UrlMembershipCondition	Determines whether an assembly belongs to a code group by testing its URL. This class cannot be inherited.
Zone	Provides the security zone of a code assembly as evidence for policy evaluation. This class cannot be inherited.
ZoneMembershipCondition	Determines whether an assembly belongs to a code group by testing its zone of origin. This class cannot be inherited.

Interfaces

IIdentityPermissionFactory	Defines the method that creates a new identity permission.
IMembershipCondition	Defines the test to determine whether a code assembly is a member of a code group.

Enums

ApplicationVersionMatch	Specifies how to match versions when locating application trusts in a collection.
PolicyStatementAttribute	Defines special attribute flags for security policy on code groups.
TrustManagerUIContext	Specifies the type of user interface (UI) the trust manager should use for trust decisions.
