The danger in using a wiki as a collaboration tool is that other people will edit it.

Some Questions / Notes from BJ

I added to the existing outline below. We only get 15 pages max, so we might have to limit ourselves to 2 pages (3 tops) per EFS, so there might be too many items for each EFS listed, but I think it would be good for us to be consistent and have the same items in each EFS.

I think we should start filling out what we can in the outline during this week, so that we can "refine as we go".

Please make sure and add your citations, also. Do not worry about format; we will do that later; but make sure all the information is there.

Suggestion of outline :

  • Introduction (BJ)
    • Definition of an Encrypting File System
    • Purpose/Goal of an EFS
      • Purpose: to add an additional layer of security, controlled by the user, over that user's data
      • Goal: to allow users to feel confident the data placed in the EFS cannot be compromised.
    • Overview of General Workings
      • (description of common functionality and common processes to all or most EFS)
      • You have data in memory, you want to save it to disk, you only want "authorized" people to see it; not even system administrators and/or backup operators
      • You control access by "owning" the key
      • Key is generated (somehow)
      • There is overhead in the process of encrypting/decrypting (unavoidable)
    • Overview of Common Usage
      • Maybe some categories of users and what they are looking for:
      • "business critical applications" like databases, etc. where business relies on data being available and secure
      • "business users" like managers who want to secure employee reviews, HR people wanting to secure salary information, etc.
      • "casual users" people who just want to make sure their data is secure.
    • The currently available systems (market share?)
    • Why we choose CFS TCFS and Network Applicances
  • Study of 4 systems in depth, including why this system is selected for study.
    • CFS (LENA)
      • Overview
        • When Developed
        • Platform(s)
        • Current Version
      • Key Management
      • Ease of Use for End Users
      • Legal Issues
      • Failure Modes
      • Challenges in Installation/Use by System Administrator
      • Performance
      • Cost
      • Conclusion (?? what would that be??)
    • TCFS (SAM)
      • Overview
        • When Developed
        • Platform(s)
        • Current Version
      • Key Management
      • Ease of Use for End Users
      • Legal Issues
      • Failure Modes
      • Challenges in Installation/Use by System Administrator
      • Performance
      • Cost
      • Conclusion (?? what would that be??)
    • Network Appliance DataForte and Seagate (ERIC)
      • Overview
        • When Developed
        • Platform(s)
        • Current Version
      • Key Management
      • Ease of Use for End Users
      • Legal Issues
      • Failure Modes
      • Challenges in Installation/Use by System Administrator
      • Performance
      • Cost
      • Conclusion (?? what would that be??)
    • Windows EFS (BJ)
      • Overview
        • When Developed
        • Platform(s)
        • Current Version
      • Key Management
      • Ease of Use for End Users
      • Legal Issues
      • Failure Modes
      • Challenges in Installation/Use by System Administrator
      • Performance
      • Cost
      • Conclusion (?? what would that be??)
  • Common Issues/Problems (ALL)
    • Impact on computer forensics
    • Impact on end-users (i.e. what if you are away on a business trip and you have to go to the hospital and all of your files are encrypted on your laptop?) (or even worse, what if you die and all your financial information is encrypted?)
    • Impact on business owners (e.g. what if an employee quits and all that person's data files, contact info, etc. are encrypted)
  • Future (ALL)
    • What would be useful to add or remove
    • How we would accomplish the changes we suggest
  • Conclusion. (ALL)

some thoughts/comments on the updated outline
  • We are examining 3 cyptographical file system - why do we choose the 3 we choose ?
    • Freeware is popular CFS, TCFS is free.
    • CFS is quite often referenced. It is one of the early most widely used system.
    • Net Applicance is a commercial system. Possibly an end-to-end solution (?)
    • Scope of this project: multi-user file systems, as oppose to a single disk drive system.
    • What are some of the existing system ?
  • Betty, it was previously agreed that there are 3 EFS. Sam prefers 3 EFS to 4.
    • I too prefer 3 to 4. As the TA joe has suggested, we should write 3 deep analysis.

Lenageraghty 23:32, 14 November 2005 (EST)

Questions :

  • What systems are currently available ?

Lenageraghty 08:48, 11 November 2005 (EST)

Suggestions/Questions/Outline ?:

  • Solutions from other storage vendors.
  • Desirable features for a cryptographical file system.
  • cost
    • performance
    • total solution for end-users
    • Key management for cryptographical file system
    • Ease of use by end-users
    • Failure modes
    • Challenges in using/installing

comment from TA (Joe)

That looks like some of the right inroads. Remember that the paper is not very long, so you may want to focus on the three systems and do a deep analysis. Certainly some things to think about:

      Simson's lecture where he talked about it
      Failure modes of such systems
      Challenges in using/installing

comment from teacher: Please remember that this Wiki is publically accessible on the Internet. It's great if you can improve the resource for everbody. But do try to do that, rather than just creating your own space...

Uploading pieces of our writeup

File:HelixCFS.doc Lena's writeup on CFS Devaition from outline:

  • Did not mention current release, which is not really relevant. (It is 1.4.1 if anyone is interested)
  • Describe the security provided by CFS.
  • No legal issue.
