Libros de seguridad informática con licencia GPL FDL

Dos libros de seguridad informática con licencia GPL FDL, en ingles claro:

• Attack simulation and threat modeling: A book that explores the abundant resources available in advanced security data collection, classification, processing and mining. It attempts to give insight into a number of alternative methods of security and attack analytics that leverage methodologies adopted from various other disciplines in extracting valuable data to support security research work and chart a course for enterprise security decision making.

• Security analysis and data visualization: This is not a book on information security assessment methodologies, neither is it on penetration testing techniques: it is however, about a subtle combination of the core elements of both, but this time employed in the process of interactive security analysis and statistical graphics.
