Hinweise

Üblichen Formen von Beweisen Signaturen und Speicherort der Ursprung des Codes enthalten möglicherweise handeln können.Common forms of evidence include signatures and location of origin of code, but can potentially be anything. Objekte eines beliebigen Typs, die durch die Sicherheitsrichtlinien erkannt werden, stellen Beweis dar.Objects of any type that are recognized by security policy represent evidence.

Security-Richtlinie besteht aus Codegruppen; eine bestimmte Assembly (die grundlegende Einheit von Code zum Gewähren von Berechtigungen für die Codezugriffssicherheit) ist ein Mitglied einer Codegruppe an, wenn er die mitgliedschaftsbedingung der Codegruppe erfüllt.Security policy is composed of code groups; a particular assembly (the basic unit of code for granting security permissions) is a member of a code group if it satisfies the code group's membership condition. Beweise sind die verschiedenen Eingaben für die Richtlinie, die mitgliedschaftsbedingungen verwenden, um zu bestimmen, zu welchen Codegruppen eine Assembly gehört.Evidence is the set of inputs to policy that membership conditions use to determine to which code groups an assembly belongs.

Die Evidence -Klasse ist eine Auflistung (finden Sie unter ICollection), enthält einen Satz von Objekten, die Beweise darstellen.The Evidence class is a collection (see ICollection) that holds a set of objects that represent evidence. Diese Klasse enthält zwei Sätze, die entsprechen, an die Quelle des Beweises: Hosten und Assemblybeweise.This class holds two sets that correspond to the source of the evidence: host evidence and assembly evidence.

Richtlinien kann Beweise aus zwei verschiedenen Quellen abrufen, bei der Auswertung von Berechtigungen für den Code.Policy can get evidence from two different sources when evaluating permissions for code.

  • Host evidence wird vom Host bereitgestellt und kann nur bereitgestellt werden, indem Hosts, die gewährt wurden die ControlEvidence Berechtigung.Host evidence is provided by the host, and can only be provided by hosts that have been granted the ControlEvidence permission. In der Regel ist dies die Beweise für den Ursprung des Codes und der digitalen Signaturen in der Assembly.Typically, this is evidence of the origin of the code and digital signatures on the assembly. Beweise Ursprung in der Regel enthält Url, Site, und Zone Beweise.Evidence about origin typically includes Url, Site, and Zone evidence. Signaturen finden Sie in der Softwareherausgeber (AuthentiCode x. 509v3-Signatur) und Identitäten für starke Namen.Signatures refer to software publisher (AuthentiCode X.509v3 signature) and strong name identities. Beide Arten von digitalen Signatur basierende Identitätsanbieter müssen werden in die Assembly integriert, jedoch überprüft und Richtlinie durch den Host übergeben werden; Beim Laden, überprüft das Sicherheitssystem die Signatur an.Both kinds of digital signature-based identity are built into the assembly, but must be validated and passed to policy by the host; when loaded, the security system verifies the signature. Das System wird dann erstellt den entsprechenden Nachweis und nur dann, wenn die entsprechende Signatur gültig ist, an die Richtlinie übergeben.The system then creates the appropriate evidence and passes it to policy only if the corresponding signature is valid.

  • Assembly evidence ist Teil der Assembly selbst.Assembly evidence is part of the assembly itself. Entwickler oder Administratoren können benutzerdefinierten Beweise zu der Assembly, die das Erweitern der Beweis für die Richtlinie anfügen.Developers or administrators can attach custom evidence to the assembly to extend the set of evidence for policy. Assemblybeweis kann nur zum Zeitpunkt der Generierung der Zielassembly, hinzugefügt werden, das auftritt, bevor die Assembly signiert ist.Assembly evidence can only be added at the time of assembly generation, which occurs before the assembly is signed. Die Standardrichtlinie des Sicherheitssystems ignoriert Assembly bereitgestellten Beweise, aber die Richtlinie kann erweitert werden, um sie anzunehmen.The default policy of the security system ignores assembly-provided evidence, but policy can be extended to accept it.
