Timmy: You said how you belong to a large corporation. Could that possibly affect the policies on how your company run's it's security measures/practices?

Compliance = Meeting the requirements as defined by a relevant standard, guideline, procedure, or policy.
Security = Totally vague. Typically "security" is related to the reduction of risk. If risk has been reduced to an acceptable level, something may be said to be "secure" (enough).
Co-sign. Security can mean anything and typically does.. it varies. Compliance means that the requirements to the standard thats set is being met (or like catch said, the procedure/policy). Now aslong as those standards, procedures, etc is being met and covers the important aspects of the policy on how things are run, then there shouldn't be much to worry about.

EDIT:
End answer... compliance is a component of security.
Agreed again, that's the bare answer IMHO.
