The sophistication and the borderless nature of the intrusion techniques used during a cyber security incident, have triggered the need for designing new active cyber defense solutions, and developing efficient incident response plans. In this context, digital forensics has emerged as a disciplined science allowing to note and collect evidences left on the compromised system prior to the incident occurrence, and carry out an analysis to: (a) understand what occurred; (b) determine the set of exploited security weaknesses; (c) trace attackers to their source; (d) study the attackers trends and motives; and (e) propose a set of optimal countermeasures to stop and mitigate the effect of the attacks.

The fourth edition of the international workshop on Security and Forensics in Cyber Space (SFCS 2016) will be held in conjunction with the 17th International Conference on Distributed Computing and Networking (ICDCN 2016). The workshop promotes research and innovative ideas in the realm of cyber security and digital forensics. It provides a prominent venue for researchers, scientists, engineers and practitioners to share their thoughts, exchange ideas, and prospect future and potential axes of collaboration. Papers focusing on any aspect of the theory and practice of cyber security, defense, and digital forensics are solicited. A large spectrum of advanced topics are covered, ranging from anti-forensics detection and recovery, cyber security and forensic in wireless and mobile communication systems, multimedia security and forensic content processing, development of novel theories and techniques of cyber security and forensics analysis and validation, and forensics in cloud computing and social networks.
