Security: Secure Sensitive Data Management
SSD Rules

- (Higher) Plaintext Only—Users are permitted to access sensitive data in 
plaintext only. Users will also have read and write permission to SSD 
parameters as well.
- (Highest) Both—Users have both encrypted and plaintext permissions 
and are permitted to access sensitive data as encrypted and in 
plaintext. Users will also have read and write permission to SSD 
parameters as well.
Each management channel allows specific read permissions. The following 
summarizes these.
• Default Read Mode—All default read modes are subjected to the read 
permission of the rule. The following options exist, but some might be 
rejected, depending on the read permission. If the user-defined read 
permission for a user is Exclude (for example), and the default read mode is 
Encrypted, the user-defined read permission prevails.
- Exclude—Do not allow reading sensitive data. 
- Encrypted—Sensitive data is presented in encrypted form. 
- Plaintext—Sensitive data is presented in plaintext form. 
Each management channel allows specific read presumptions. The 
following summarizes these.
* The Read mode of a session can be temporarily changed in the SSD 
Properties page if the new read mode does not violate the read permission.
