ANTICLICK: INCREASING DESKTOP SECURITY Jason Petrey Computer Electronic Networking Dept. of Technology Eastern Kentucky University

OUTLINE Basic Idea Motivation Password Security Problem Statement Solution Conclusion Future Work 2

3 SECURITY GAP Windows user passwords are not secure enough There is a need for a security application to protect a user after the log on process, so I developed one

4 MOTIVATION During my studies at EKU I was shocked at how unsecure the windows user password is. I remembered a security program that I had started in high school. Now had the knowledge and skills needed to complete the program I had started in high school.

5 PASSWORD SECURITY In 2003 a Swiss researcher reduced the time it takes to crack a password like a windows users password from little less than 2 minutes to 13.6 seconds. (Lemos, 2003)

7 PROBLEM STATEMENT With the lack of security in windows user passwords a program is needed to protect a user account after the user logs on.

8 PROPOSED SOLUTION Anticlick: Screen Lock Clear form covering the entire screen. Blocks key combinations that could normally bypass the program. Requires pressing two keys, defined by the user, to bring up password entry, settings, or change password screens

9 PROPOSED SOLUTION Anticlick: Screen Lock (cont.) Ability to run on startup/log on and text message warnings on a user defined number of failed attempts at the password All information protected with 3DES encryption (a three-step data encryption algorithm )

10 PROPOSED SOLUTION Anticlick: Administrator Control Panel Provide administrator override password that will work for any user Allows an administrator to edit anticlick settings on all local users who have already ran Anticlick: Screen Lock All information protected with 3DES encryption

KNOWN VULNERABILITIES Operating system that boot from removable media Safe Mode An occasional bug that places the start bar above the for that blocks mouse key strokes. 16

17 CONCLUSIONS When run on startup Anticlick is an effective invisible layer of protection for a user. When ran manually it makes an effective screen lock. When working with Visual Basic always start research on MSDN (Microsoft Developer Network)

CONCLUSIONS It is surprisingly easy to integrate functions from external Dynamic-link libraries and windows API (application programming interfaces) functions into programs using Visual Studio, which helps a programmer create programs. 18

19 FUTURE WORK Multiple monitor support Windows service integration Remove the assumptions about the host system that are hard coded to increase compatibility

20 FUTURE WORK Administrator Control Panel to establish settings for users who have not yet ran the Anticlick: Screen Lock Sell for profit or distribute as freeware /shareware Permanent
