Security Library Recommendations
I would like to know what books are in your SAP Security library and why they are useful. As with most things, I am always searching for new insight/knowledge to better develop my understanding of subject areas I would like to specialize in. I noticed that besides ADM940 (which I took several years ago), there doesn't seem to be a whole lot of SAP Security books on hand, particularly on the newer topics of security such as addressing the Java stack, BI/SRM/CRM security, modern design methodologies, etc. Most either regurgitate the basics of ABAP security (i.e. plug random transaction codes to roles in PFCG) or aim to be "cookbooks" of Security Q/A, which are very limited in their usefulness and varies in their accuracy.
What, if any, books would you recommend that any modern-day Security consultant shouldn't be without? Very interested in any recommendations people might be able to bring up!
