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.

Pointsec for PC

• If a drive is lost or stolen, the encrypted partitions and everything on them are reasonably secure.

• Meets certain legal requirements

19

What it isn’t

• Pointsec for PC is not a complete encryption solution– Currently limited to 2000 and XP– Only encrypts partitions– Does not encrypt network drives

20

Features

• Whole disk encryption• Multiple user access• Configuration options• Recovery tools• Enterprise management

– Logging– Enforceable policies– Permissions

21

Experience

• Login screen at boot• System tray icon• Transparent to OS• Minimal performance impact

• While encrypting:

• Fully encrypted:

How to install

• Available to individuals and departments• Check requirements• Request license from IET Security• Decide on default or custom configuration• Get install media• Return recovery file• After encryption completes return log file

26

Requirements

• Windows 2000, XP and Vista soon• No dual boot• No servers• No fancy disk configurations

• Encryption proceeds at 10-20GB/hr• Depends on disk size not amount of data• System can be used, shut down or

rebooted• After encryption completed grab log file

31

Support

• Remote password reset• Managing users• Uninstall• Updates and upgrades• Recovery disk• Bart’s disk

34

Managing Users

• Types of users– Normal, Service, Temp

• Types of permissions– Privileged and plain permissions
