Application layer security for the APIs is similar to what is used by the Primavera client/server products. Global and project security profiles apply when using the APIs, so if a user attempts to perform an action that is restricted by a security profile, an exception will be thrown.
Network layer security is achievable by using SSL.
Note: If you are using the P6 Integration API, see the section entitled "Java Security Manager" in the P6 EPPM Integration API Configuration Guide for information on how to enable additional security through the use of a custom security policy.
