Digital Forensic is the preservation, identification, recovery, documentation, analysis, and interpretation of digital evidence. Digital evidences are electronically stored records, facts, signs, information of probative value that shows clearly that an event occurred or that a crime has been committed. Preservation of Digital Evidence is the crux of Digital Forensics. As such, it must be handled in a way to ensure that it is promptly identified, preserved, collected, examined, analyzed and documented appropriately so that it is evidently weighty, authentic, reliable, believable, complete and that it passes the test of legal admissibility. Evidence Preservation is being constantly plagued with issues needed to be technically, administratively and legally resolved. Of which is, the rate of standardization of Digital Forensics Processes, particularly evidence preservation, by International standardizing bodies is slower than the challenges and continuously evolving digital technology. Consequently, Proactive, Sustained and Non-fragmented Research and Practitioner Communities must be established, where they do not exist and also supported by national and regional standardization organizations, to see to faster and up-to-date solutions. Such communities have greatly helped to sustain continuous growth and standardization in other fields such as software engineering, web frameworks, and mobile technology. A consolidated framework, the Enhanced Generic Digital Forensic Investigation Model (EGDFIM), is proposed in this work.

Megacity Stakeholders prioritise to protect these cities from threats rather than just reactively responding to them, however the success of managing these cities hinges on the availability of evidences (data) to justify decisions. The challenge is that the sources of evidences are very diverse and dynamic in these cities. Using the proposed model (MEDFORM), we seek how evidences can be aggregated and integrated from the diverse sources, model future events and threats using the evidences, to plan, build and manage such mega cities. Lagos State University, a megacity University community in an emerging megacity like Lagos, is used as a test case study for the model.

As  megacities  emerge  in  splendor, so  also do  threats  to  security  and sustainability of these cities. Earlier research found out that the leading threat amongst several security and safety threats in megacities are organized crimes. Since technology is involved in all facets of megacities, including the threats therein, this paper seeks to stimulate scientific curiosity in finding out effective and sustainable ways of harnessing technology  in  readiness,  to  protect  these  cities  from  threats  rather  than  reactively responding to them.

A  Megacity  Digital  Forensic  Readiness  Model  (MEDFORM)  is proposed in this presentation.
