Searching for personal information

• Data focus: credit card numbers and Social Security numbers

• UCD supported products: Cornell Spider and PowerGREP

6

Mitigating Risk of Exposure of Personal Information

• Higher cost (time, tools) for administering a system containing personal information.

• IET supports the Cyber-safety program and a number of tools that assist in protecting personal information, including Tripwire, Spider/PowerGREP, self-directed Nessus scans, and Pointsec.

7

Maintain a list of systems containing sensitive data

• Catalog the system name, IP, owner, type of service running on the system, type of sensitive data residing on the system

• Share this information with the technical support staff and the unit administrative managers

• Confirm and update this information on a regular basis

8

Monitor when the data is accessed or modified

• Use Tripwire to identify file and directory changes.

• Write logs to a central logging server (syslogng, snare, MOM).

• Turn on auditing of successful and unsuccessful logins.

• Read your logs on a regular basis.

9

Restrict access to the system and its sensitive data

• No group accounts (cannot audit access)• Access system and data using encrypted

protocols such as ssh (sftp, scp), ssl (https), rdp, ipsec

• Evaluate physical security• Use host-based and hardware firewalls

10

Use, share, or transfer restricted data in a safe manner

• Do not use email to send unencrypted restricted data.

• Do not use restricted data as a key in a database.

• Do not use restricted data on a test or development system.

• When sharing restricted data, ensure that users are aware that the data should be handled carefully and in compliance with policies.
