Enum InterNodeCommunicationAuthenticationService.Role

java.lang.Enum<InterNodeCommunicationAuthenticationService.Role>

com.aquenos.cassandra.pvarchiver.server.internode.InterNodeCommunicationAuthenticationService.Role

All Implemented Interfaces:

Serializable, Comparable<InterNodeCommunicationAuthenticationService.Role>

Enclosing class:

InterNodeCommunicationAuthenticationService

public static enum InterNodeCommunicationAuthenticationService.Role
extends Enum<InterNodeCommunicationAuthenticationService.Role>

Role for which a client authenticated. The role defines the kind of resources the client may access.

In general, the PRIVILEGED role is used for inter-node communication. However, this role depends on an authentication token that involves a time stamp. Therefore, authentication on this level might not work if there is a significant clock skew between servers. For applications where communication should still be possible under such circumstances, the UNPRIVILEGED role can be used. This role uses a fixed token. Obviously, this role should never be used for sensitive services because an attacker gaining access to the shared secret once (e.g. by listening on the network wire) will be able to authenticate with this role indefinitely.

Enum Constant Detail

NOT_AUTHENTICATED

public static final InterNodeCommunicationAuthenticationService.Role NOT_AUTHENTICATED

Authentication was not successful.

UNPRIVILEGED

public static final InterNodeCommunicationAuthenticationService.Role UNPRIVILEGED

Authentication for unprivileged access. Unprivileged access means that only resources that do not affect the operation may be accessed (e.g. read-only access to insensitive data).

PRIVILEGED

public static final InterNodeCommunicationAuthenticationService.Role PRIVILEGED

Authentication for privileged access. Privileged access means that sensitive resources may be accessed.

Method Detail

values

public static InterNodeCommunicationAuthenticationService.Role[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (InterNodeCommunicationAuthenticationService.Role c : InterNodeCommunicationAuthenticationService.Role.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static InterNodeCommunicationAuthenticationService.Role valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
