Ripped from the headlines... UCLA laptop theft exposes ID info Representatives of the University of California, Los Angeles, are warning 145,000 blood donors they could be at risk for identity theft due to a stolen university laptop. June 10, 2004 Boston College reveals alumni data breach Boston College is fighting against an attack on its fund-raising databases, which may have exposed the personal data of more than 100,000 alumni. March 17, 2005 ChoicePoint data loss may be higher than reported ChoicePoint could have leaked information on far more than 145,000 U.S. citizens, the data collector's latest filing to the Securities and Exchange Commission suggests. March 10, 2005 Laptop theft puts data of 98,000 at risk The University of California, Berkeley, is warning more than 98,000 people that the theft of a laptop from its graduate school admissions office has exposed their personal information. March 29, 2005 UCD computer hacked into from Internet The names and Social Security numbers of about 1,100 UC Davis students, faculty, visiting speakers and staff may have been compromised when someone hacked into a main computer in the university’s plant biology section last month. April 5, 2005

To help protect against identity theft, California enacted a new law (SB 1386) requiring businesses and government agencies beginning July 1, 2003, to notify consumers if hackers gain entry to computers that contain unencrypted personal information such as credit card numbers, pass codes needed for use of personal accounts, Social Security numbers or driver’s license numbers.

Policy and Procedure Manual UC Davis Cyber-Safety Program I. Purpose and Scope This policy establishes that devices connected to the UC Davis electronic communications network must meet UC Davis security standards or seek exception authorization. Campus units may develop and implement more rigorous security standards.… • Section 310-022 http://manuals.ucdavis.edu/ppm/310/310-22.htm

Policy and Procedure Manual UC Davis Cyber-Safety Program III. Policy C. Campus units must annually report to their respective Dean, Vice Chancellor or Vice Provost, the extent to which unit operations are consistent with the campus security standards. Where compliance is not complete, the report must document a compliance plan… • Section 310-022

UC Davis Computing Standards • Annual checklist includes14 Standards • 7 Level 1 Practices: “Highest priority” standards that apply to all computers on the network • 7 Level II Practices: “Secondary priority” standards, some of which apply to servers or system administrators YourMission http://manuals.ucdavis.edu/ppm/310/310-22a.htm

Computing Security Standards • I-A. Software Patch Updates Computing hosts connected to the campus network must use an operating system and application software for which the publisher maintains a program to release critical security updates. Campus units must apply all currently available critical security updates within seven calendar days of update release or implement a measure to mitigate the related security vulnerability. Exceptions may be appropriate for patches that compromise the usability of an operating system or application or for patches for which the installation is prohibited by regulation.

Computing Security Standards • I-A. Software Patch Updates

Computing Security Standards • I-B. Anti-virus software Anti-virus software must be running and updates must be applied within no more than 24 hours of update release for computing hosts connected to the campus network. This standard applies to computing hosts connected to the campus network which are subject to virus infection. Networked devices subject to virus infection that are unable to use anti-virus software must be protected from malicious network traffic.

Computing Security Standards • I-B. Anti-virus software

Computing Security Standards • I-C. Insecure Network Services If a computer service/process that provides a computing host access to network services (e.g, Telnet, FTP, POP) is not necessary for the intended purpose or operation of the network-connected device, that service/process shall be disabled. Where inherently insecure network services are needed, their available encrypted equivalents must be used

Computing Security Standards • I-C. Insecure Network Services

Computing Security Standards • I-D. Authentication Campus electronic communications service providers must have a suitable process for authenticating users of shared electronic communications services under their control. 1) No campus electronic communications service user account shall exist without passwords or other secure authentication system, e.g. biometrics, Smart Cards.

Computing Security Standards • I-D. Authentication - Passwords

Computing Security Standards • I-D. Authentication - Passwords 2) Where passwords are used to authenticate users, a password must be configured to enforce password complexity requirements, if such capability exists.

Computing Security Standards I-D-2. Password Complexity Mac OS X 10.4 “Tiger” offers a password assistant when setting or changing passwords that can offer suggestions and rate passwords for complexity and strength.

Computing Security Standards I-D-2. Password Complexity

Computing Security Standards • I-D. Authentication - Passwords 3) All default account passwords for network-accessible devices must be modified upon initial use.

Computing Security Standards • I-D. Authentication - Passwords 4) Passwords used for privileged access must not be the same as those used for non-privileged access.

Computing Security Standards • I-D. Authentication - Passwords 5) All campus devices must use encrypted authentication mechanisms unless an exception has been approved by the appropriate department head or campus administrative official. Unencrypted authentication mechanisms are only as secure as the network upon which they are used. Any network traffic may be surreptitiously monitored, rendering unencrypted authentication mechanisms vulnerable to compromise.

Computing Security Standards • I-E. Personal Information Campus units must identify departmental computing systems and applications that house personal information (personal name along with Social Security number, California driver identification number, or financial account information). Personal information must be removed from all computers for which it is not required. Note from Paul: Use “Secure Empty Trash!”

Computing Security Standards • I-F. Physical Security Unauthorized physical access to an unattended computing device can result in harmful or fraudulent modification of data, fraudulent email use, or any number of other potentially dangerous situations. In light of these risks, where possible and appropriate, devices must be configured to “lock” and require a user to re-authenticate if left unattended for more than 20 minutes. Portable storage devices must also not be left unattended and be protected from data theft or unauthorized data modification or deletion.

Ripped from the headlines... Carjackers swipe biometric Merc, plus owner's finger A Malaysian businessman has lost a finger to car thieves impatient to get around his Mercedes’ fingerprint security system. Accountant K Kumaran, the BBC reports, had at first been forced to start the S-class Merc, but when the carjackers wanted to start it again without having him along, they chopped off the end of his index finger with a machete.

Computing Security Standards • II-A. No Open E-mail Relays Devices connected to the campus network must not provide an active SMTP service that allows unauthorized third parties to relay email messages, i.e., to process an e-mail message where neither the sender nor the recipient is a local user

Computing Security Standards • II-B. Proxy Services An unrestricted proxy server for use from non-university locations is not allowed on the campus network. Use of an unauthenticated proxy server is not permitted on the campus network unless approved as an exception to the campus security standards by the appropriate department head or campus administrative official.

Computing Security Standards • II-C. Audit Logs Campus units must develop and implement a policy defining the use, inspection and retention of audit logs. Audit log inspection may permit the identification of unauthorized access to sensitive electronic communication records. The use of audit logs should be extended to document activities such as account use and the network source of the login, incoming and outgoing network connections, file transfers and transactions.
