Study material

Though I have some idea about these but if you can suggest me good books or online material which I can refer to consolidate my Audit knowledge.

The areas to be audited are as below(in one of the organisations):

• Physical Security
• Device / Data Security
• Human Resource Security
• IT Environment management
• Business Information Processing
• Access to Applications & Network
• Privacy (data)
• Backup / Recovery
• Incident / Problem Management
• Business Continuity
• Vendor & Contract management
• Client contract management

Answer: Considering ISO standards, I suggest you to take a look at the following materials:
- ISO 27001:2013 Internal Auditor Course https://advisera.com/training/iso-27001-internal-auditor-course/
- Book Becoming Resilient: The Definitive Guide to ISO 22301 Implementation https://advisera.com/books/becoming-resilient-the-definitive-guide-to-iso-22301-implementation/
- ISO 27001 Annex A Controls in Plain English https://advisera.com/books/iso-27001-annex-controls-plain-english/
- ISO Internal Audit: A Plain English Guide https://advisera.com/books/iso-internal-audit-plain-english-guide/

These material will provide you a comprehensive view of such diverse subjects in a not-so-large number of sources of information.

You also can consult the articles in our knowledge base (https://advisera.com/27001academy/knowledgebase/). There you can find materials divided in subjects covering the topics you mentioned.
