Other
| Goal | Task | Reasoning | Implemented? | Notes |
|---|---|---|---|---|
| Erasure Environment | Setup Alpine Linux Environment with SquashFS/No Persistence | Lightweight Linux Distro that can be loaded into RAM and be edited. Avoids wiping USB but also can be used on any machine and customized. |
Yes | |
| Scripted Erase Tool | Write a script to guide the erase process | Allows for ease of use, and ensures consistent workflow Can also tie in user auth, logging, etc |
Yes | Done via bash scripting in erase_drive.sh |
| User Authentication | Implement user authentication | For Auditing, Logging, connection to network shares, etc. | Testing | Probably kerb auth via krb5 |
| Logging | Implement logging | For auditing purposes | Testing | Record user, drive serial, grab user list (if windows/unix drive), grab hostname, record script inputs |
| Ticket Notes | Add ticket note through script | To keep keyword searchable records associated with a ticket | No | Send email to Otobo with small details such as level, hostname, serial, etc Might involve policy changes for when a ticket should be created. |
