Interested in doing research in computer forensics? Looking for a master's topic, or just some ideas for a research paper? Here is my list. Please feel free to add your own ideas.

Stored Data Forensics

Flash Forensics

  • Access the physical layer of SD cards and/or USB flash devices. Reverse-engineer the Flash Translation Layer to find deleted data and files.

SleuthKit Enhancements

  • Add support for a new file system:
    • YAFFS2 flash file system. (YAFFS2 is currently used on the Google G1 phone.)
    • JFFS2 flash file system. (JFFS2 is currently used on the One Laptop Per Child laptop.)
    • XFAT
  • Enhance support for an existing file system:
    • EXT4
    • Add support for NTFS encrypted files.
    • Report the physical location on disk of compressed files.
  • Write a FUSE-based mounter for SleuthKit, so that disk images can be forensically mounted using TSK. (I've already started on this if you want the code.)

fiwalk Enhancements

  • Rewrite the metadata extraction system.

Stream Forensics

  • Process the entire disk with one pass, or at most two, to minimize seek time.

Evidence Falsification

  • Automatically detect falsified digital evidence.

Sanitization

  • Detect and diagnose sanitization attempts.


Timeline Analysis

Write a new timeline viewer that supports:

  • Logfile fusion (with offsets)
  • Logfile correlation
  • View logfiles in the frequency domain.

Cell Phone Exploitation

Imaging

  • Image the contents of a cell phone physical memory using the JTAG interface.

Interpretation

  • Develop a tool for reassembling information in a cell phone memory


Corpora Development

Realistic Disk Corpora

There is need for realistic corpora that can be freely redistributed but do not contain any confidential personally identifiable information (PII).

These disk images may be either of an external drive or of a system boot drive. The drive images should have signs of wear --- that is, they should have resident files, deleted files, partially overwritten files, contiguous files, and fragmented files.

Realistic Network Traffic

Generating realistic network traffic requires constructing a test network and either recording interactions within the network or with an external network.
