8. Methodology/2
●
●
●
3 methodologies & the detailed process varies
○ Basic Forensic Methodology
○ Cyber Tool Online Search For Evidence (CTOSE)
○ Data Recovery UK (DRUK)
the recommended methodology combines the practice from 3 standards
there are more than dozen DF frameworks

12. Challenges/3
●
●
●
●
●
Evidence-oriented design influences today’s DF research
○ find evidence instead of assisting investigation
○ not think of cyber-crime, i.e tools are not for hacking cases
○ not possible to perform short-time analysis
○ not capable of generating data from residual file
Visibility,Filter,Report Model
○ data recover before making analysis
○ not possible to do parallel processing
no standard for reverse engineering
‘application instead of tools’ concept by vendors
lost academic research

●
●
●
2013 survey takes part in 4 categories:
○ Demographics, Forensic Capabilities, Future Challenge, Legislative Concerns
more than 50%: 3 years of DF experience
Current DF tools & Capabilities:
○ Importance: more than 98% ranks as 4 out of 5
○ Key Limitations: Data Volume, TIme,Tool Capability
○ Tool Capability: not clear result
Technology that least concerns: malware, steganography
2013, Challenges to Digital Forensic

14. Future Research
●
Challenge: Investigation & Analysis Time
●
Mobile and Network Forensic will be trending
●
anticipated future challenge: Cloud Computing, Anti-forensic, Encryption,Social Networking
●
Should adopt standards for case data, data abstractions and composable models
●
more data abstractions should create
●
should standardise development diversity
●
alternative analysis model: parallel processing, stochastic analysis ...
●
doesn’t work in small-scale dataset
●
standardized test data
