Find Resticted Information
What is SENF?
SENF stands for sensitive number finder. It is used to look for social security (SSN) and credit card (CCN) numbers on computer disks and other computer storage, such as network drives. Sometimes colleagues are unaware they might have SSN/CCN data on their computer. Periodically conducting a scan using this program can help protect sensitive data from being compromised.
Do I need to use SENF?
If you know you occasionally, temporarily or regularly store restricted information on your computer - don't run SENF, call the Help Desk and get your computer encrypted. SENF is for people who are confirming they have removed all SSN/CCN numbers from their computer.
How do I use SENF?
- Make sure Java is installed on the computer that will run SENF
(a basic Java test is available on the Java website).
- Download the SENF file to your computer
- XP - downloads will tend to go to your desktop - right-click to save to a specific folder
- Mac - downloads will go to desktop or downloads folder - control-click to save to a specific folder
- Vista/7 - downloads will tend to go to your downloads folder - right-click to save to a specific folder
- Extract those files
NOTE: If you don't extract the files in Windows, SENF will launch but won't run.
- Windows - Right-click the senf-haku-340.zip file and choose "Extract all..." Then click next/finish all the way through the extraction wizard to extract the files. This should then open the folder where the files were extracted.
- Macintosh - Double click senf-haku-340.zip file. Open the folder that is created with a similar name.
- Double-click the senf.jar file to run the program (icon will have a little coffee cup, as with Mac, Vista, XP)
- Uncheck the following options:
- Report err..
- Check max file size
- Check last modified date?
- Change the path in the SENF box labeled "Root scan path:" to the path you want to scan. Suggested paths are:
- Whole Drives
- Windows: C:\ or S:\ (or another drive letter where you store data, e.g. U:)
- Macintosh: /
- User Area of the Drive
(where <userid> is your userid on that computer, e.g. /Users/kcary, etc.)
- Windows: C:\Documents and Settings\<userid>
- Macintosh: /Users/<userid>
- Whole Drives
- To run the program click the Scan button and let SENF run until you see the message: Done. xxx matches found. in the upper pane.
- In the lower pane, click each match and determine if this reported match is really a sensitive number. On the other hand, you may be able to tell from looking at the path to the matched files that they are indeed restricted information.
