22 Auditing a service provider after a cyber attack Forensic investigative and analytical skills and abilities are needed Technical skills Building a digital audit trail Understand computer fraud techniques Understand information collected from various computer logs Understand the inner workings of web servers, firewalls, attack methodology, security procedures & penetration testing 22

23 Auditing a service provider after a cyber attack Forensic investigative and analytical skills and abilities are needed Review: Computer Incident Response Plan and its performance after the cyber attack Chain-of-custody process Information Security Policies and Procedures Organizational and legal protocols for incident handling 23
