Keystore

Purpose

A Keystore object is representing a location where a collection of login credential information such as Active Directory, Kerberos or a local directory of private keys. The essence of the Keystore object is that if an attacker manages to read it, it will give access to login information/credentials (UserAccounts) or encryption keys needed to decrypt Dataflow and Datastore when needed.

Connections

 

Object	Connection	Description	Function
Host	Keystore Execution	A connection to a Host object denotes that the Keystore is hosted by the Host.	A missing connection to a Host prevents Read access through Hosts.
Client	Keystore Execution	A connection to a Client object denotes that the Keystore is hosted by the Client.	A missing connection to a Client prevents Read access through Clients.
Service	Keystore Execution	A connection to a Service object denotes that the Keystore is hosted by the Service.	A missing connection to a Service prevents Read access through Services.
WebApplication	Keystore Execution	A connection to a WebApplication object denotes that the Keystore is hosted by the WebApplication.	A missing connection to a WebApplication prevents Read access through WebApplications.
Dataflow	Authentication	A connection to a Dataflow object denotes that the key to decrypt the Dataflow is stored in the Keystore.	A missing connection to a Dataflow prevents the Attacker from bypassing the encryption and authentication on the Dataflow through a Keystore.
Datastore	Authentication	A connection to a Datastore object denotes that the key to decrypt the Datastore is stored in the Keystore.	A missing connection to a Datastore prevents Read access to an encrypted Datastore through a Keystore.
UserAccount	Authentication	A connection to a UserAccount object denotes that the credentials to the UserAccount is stored in the Keystore.	A missing connection to a UserAccount prevents compromise to a UserAccount through a Keystore.

Applicability

Since a keystore is defining where encryption/access keys are located, connecting a keystore to a datastore is only applicable when the datastore is encrypted. If not, you will not need any keys to read it once you reach it.

Attack Steps and Defenses

 

Attack Step	Description	Leads to
Read	Reading the contents of the Keystore.	Dataflow: Eavesdrop Dataflow: ManInTheMiddle Datastore: Read Datastore: Write UserAccount: Compromise
Delete	Deleting the contents of the Keystore.	Dataflow: DenialOfService Datastore: Delete Datastore: Dataflow.DenialOfService

Defense	Description	Impact	Default
Encrypted	Whether the data in the Keystore is encrypted or not.	An Encrypted Keystore can help prevents Read.	Off
