What if I want more specific guide lines on what to do before getting a SAS 70 Audit?

Groups such as the Information Systems Audit and Control Association (ISACA) and The IT Governance Institute have published many frameworks and guides for information security and auditing. Other standards that companies may be required to adhere to (such as PCI-DSS etc.) may actually have more specific requirements that can easily be used to create policies and procedures that will allow a SAS 70 audit to be performed.
