Greetings! First post. I am being asked to make sure that a DR plan, where they are really asking for a BCP with a DR plan (BCP being my specialty), is ISO 27001 compliant. If I raise them to NIST 800-53 compliant, using a crosswalk document that I found, can anyone here confirm that 800-53 is a good equivalency? I believe it is, but I am asking in a few online groups. Many, many thanks in advance for your comments!
