Minimum Standards
for Connecting Microsoft Windows-based Desktop Computers and Servers
to the UCOP Network
Issued:
January 26, 2005
The following
requirements bring MS Windows-based computers into conformance with
UCOP IT security requirements. The requirements apply to all MS Windows
computers intending to connect to the UCOP network, including those
owned by UCOP as well as other MS Windows computers used for University
business purposes.
.
Please contact
the Technology Service Desk if you are uncertain how to implement these requirements.
These requirements may change; updates will be documented in the UCOP
Electronic Information Security Policy, section IV, "Revision History."
.
In addition,
Microsoft has extensive security
recommendations for its products.

Windows-based
Desktop Computers
Devices that
fit the following criteria are subject to the minimum standards for
connecting desktop and laptop computers to the UCOP network. (See the
section below, Windows Servers, for additional requirements for servers.)
--a single user device, such as a laptop or desktop computer, that does
not perform file serving functions
--a device that operates
with software that can be configured or modified from elsewhere on the
network
--a device that does not contain
any "restricted" data
--a device that does not provide
an "essential" service
- IR&C may specify which version of the Windows operating
system UCOP computers must utilize. Older versions may be vulnerable
to attacks which cannot be mitigated. As of Fall 2004, Windows XP
Professional with Service Pack 2 is highly recommended.
- All security related software updates that are prescribed
by IR&C, including but not limited to Windows Critical Updates
and Service Packs (all applications with available security updates
to known vulnerabilities, such as Microsoft Office), must be applied
immediately upon release.
- Antivirus software, e.g., Symantec AntiVirus, must be installed
and active, and the virus definitions must be kept up-to-date. Antivirus
software must either be configured to be managed by the central antivirus
server or be configured for immediate virus definition update.
- All computers must be configured to require a login upon
booting or restart and before exiting "sleep" or screen-saver modes.
- The built-in local administrator account name must be renamed
(it cannot be "Administrator"), and its password and all
other passwords changed to meet or exceed the requirements of UCOP's
password policy.
- The built-in local administrator account shall not be
used as the primary user account. Normal user accounts, e.g., the
accounts used to log into the computer for normal operation, shall
not be a member of the local host's administrator group.
- The Guest account must be disabled.
- Generic or anonymous access must be disabled.
- All
computers must be registered with the Technology Service Desk including their location, the MAC address of the NIC(s),
and the names of the primary users. The computer name must follow
the standard convention of department ID followed by first initial
plus full last name of the primary user up to 8 characters (or a similar
format that facilitates the identification of the computer's primary
user). If the naming of the computer must deviate from the convention
as dictated by the specific business use of the machine, it
must be registered with the appropriate IT personnel along with the
contact information of the primary user.
- Any server-type applications and services running on the
computer must be inspected by the appropriate IT personnel for appropriate
configuration with respect to security compliance prior to the computer's
deployment.
- All software must be installed with prior approval of departmental
IT personnel. IT personnel reserve the right to remove all unapproved
software on UCOP-owned computers.
- E-mail, telnet, and/or FTP software shall be configured
to use only encrypted transmission for authentication.
Windows
Servers
Servers,
including any computers performing file serving functions, running the
Windows operating system can only be connected to the UCOP network if
they meet both the requirements listed above for desktop and
laptop computers and the following conditions:
- Servers must be registered with IR&C using the UCOP server registration
form available from the IR&C Technology Service Desk. IR&C will verify compliance with these requirements.
- Any server running critical services or on which sensitive data
resides must be in a physically secure location, e.g., in a locked
room or facility with restricted authorized access. See B&FB
IS-3 for definitions of criticality or sensitivity.
- Dell
OpenManage (or equivalent) must be installed.
- All unnecessary or unused services must be disabled.
- Server configuration must be fully documented.
- Servers must be configured with NTFS.
- All NTFS file permissions must be changed to ensure that only authorized
access is allowed for all files. In particular, the Everyone group
must be carefully managed to prevent unauthorized access to restricted
data.
- Any change to a registered server affecting compliance with these
requirements must be reported to IR&C prior to implementation.
