This class provides a mechanism for specified named permissions
related to the Java security framework. These permissions have no
associated actions list. They are either granted or not granted.
Permission Name | Permission Allows | Risks |
---|
createAccessControlContext |
Allows creation of an AccessControlContext |
The new control context can have a rogue DomainCombiner, leading
to a privacy leak |
getDomainCombiner |
Get a DomainCombiner from an AccessControlContext |
Access to a DomainCombiner can lead to a privacy leak |
getPolicy |
Allows retrieval of the system security policy |
Malicious code can use information from the policy to better plan
an attack |
setPolicy |
Allows the security policy to be changed |
Malicious code can give itself any permission it wants |
getProperty. key |
Retrieve the property specified by the key |
Malicious code can use information from the property to better plan
an attack |
setProperty. key |
Allows changing of the value of all properties implied by key |
Malicious code can insert rogue classes to steal keys or recreate
the security policy with whatever permissions it desires |
insertProvider. key |
Allows the named provider to be added |
Malicious code can insert rogue providers that steal data |
removeProvider. key |
Allows the named provider to be removed |
A missing provider can cripple code that relies on it |
setSystemScope |
Allows the system identity scope to be set |
Malicious code can add certificates not available in the original
identity scope, to gain more permissions |
setIdentityPublicKey |
Allows the public key of an Identity to be set |
Malicious code can install its own key to gain permissions not
allowed by the original identity scope |
SetIdentityInfo |
Allows the description of an Identity to be set |
Malicious code can spoof users into trusting a fake identity |
addIdentityCertificate |
Allows a certificate to be set for the public key of an identity |
The public key can become trusted to a wider audience than originally
intended |
removeIdentityCertificate |
Allows removal of a certificate from an identity's public key |
The public key can become less trusted than it should be |
printIdentity |
View the name of the identity and scope, and whether they are
trusted |
The scope may include a filename, which provides an entry point for
further security breaches |
clearProviderProperties. key |
Allows the properties of the named provider to be cleared |
This can disable parts of the program which depend on finding the
provider |
putProviderProperty. key |
Allows the properties of the named provider to be changed |
Malicious code can replace the implementation of a provider |
removeProviderProperty. key |
Allows the properties of the named provider to be deleted |
This can disable parts of the program which depend on finding the
provider |
getSignerPrivateKey |
Allows the retrieval of the private key for a signer |
Anyone that can access the private key can claim to be the
Signer |
setSignerKeyPair |
Allows the public and private key of a Signer to be changed |
The replacement might be a weaker encryption, or the attacker
can use knowledge of the replaced key to decrypt an entire
communication session |
There is some degree of security risk in granting any of these
permissions. Some of them can completely compromise system security.
Please exercise extreme caution in granting these permissions.
The list of valid permission names is:
createAccessControlContext
getDomainCombiner
