This policy applies to all University workforce, faculty and student members (including, but not limited to: faculty, staff, students, temps, trainees, volunteers, and other persons as deemed appropriate) while conducting/performing work, teaching, research or study activity using University resources and includes all facilities, property, data and equipment owned, leased and/or maintained by the University or affiliates
July 23, 2007
The Information Technology division is responsible for the provision and management of enterprise-wide local area network services, including wireless networks. All connections to the network must be via university-approved mechanisms. Only authorized Information Technology staff may access, install, manage or make changes to network infrastructure equipment including but not limited to enterprise servers, routers, switches or telecommunications equipment.
REASON FOR POLICY
The university will provide the required infrastructure for enterprise-wide local area network services, (including wireless) and connections to the internet, internet-2 and other external networks. This policy sets forth standards and requirements for configuring and connecting to the university’ network in order to maintain security, integrity and availability of resources.
Information Technology provides all network address assignments.
Unauthorized university network installations or modifications will be denied IP addresses for computing devices on the unauthorized network. Such devices will be physically disconnected from the university network and the device's IP and/or MAC addresses will be blocked from university network access. Note: This includes wireless networks not connected to the university's enterprise network and/or private network devices operating within university facilities or university campuses.
All internal network devices including but not limited to routers, firewalls and access control servers, have unique passwords and other appropriate access control mechanisms. The internal network will be secured from external channels.
All perimeter network devices within the university network are configured to meet hardening guidelines and to deny unnecessary services, connections and untrusted networks.
An inventory of all connections to external voice and data networks and direct connectivity to all non-university entities or untrusted networks is maintained.
Internal information system addresses, configurations, products and design information is restricted so that it is not accessible to unauthorized internal or external users.
Implementation of non-standard, business required modification to network perimeter devices is the responsibility of university IT and must include a risk assessment and implementation of mitigating controls.
Connecting to university and affiliated computing resources from outside the university network
All connections to these resources (servers, personal computing devices, networking equipment, etc.) must, except as noted, follow these standards:
Be via a secure and/or encrypted connection such as a VPN, secure HTTP, secure FTP, SSH, or other secure and/or encrypted method.
Pass through a university standard access control point (e.g., firewall, gateway, etc.) that includes an approved user authentication.
VPN/Remote connections will be configured: Remote connections will be configured:
To time out after a period of inactivity
So that after a specified amount of consecutive failed log-on attempts an account will be suspended for a period of time.
So that aaccounts are deactivated if not used within a specified period.
If the connection is by a vendor or other third party (not faculty, staff or students) an Acceptable Use Agreement must be completed. The original completed Acceptable Use Agreement must be received by the IT Security and Accounts Management team before the connection is allowed. Note: The "Acceptable Use Agreement" documents the vendor or partner's agreement to abide by the ISO-007 User Accounts and Acceptable Use Policy and to maintain their systems and practices to at least the applicable university policies and standards.
Remote access services used for occasional connections should be disabled except when required for authorized remote access.
Exception: If the connection does not allow access to sensitive information then a properly configured and administered connection method is acceptable and no log-on is required. Example: A web site providing information intended for public availability could use standard HTTP access.
Faculty, staff and administrators with university Active Directory accounts may request secure personal drive space accessed via the network shared drives for individual use (commonly called the "H" drive).
The university enterprise network drives also include a shared storage area (commonly called the "I" drive). Space in this area is used by departments to store shared data and is allocated by academic or administrative unit. Account holders have read/write access to sub directories as appropriate.
Monitoring/Altering Network Traffic
Users are expected to utilize end user systems and applications such as network drive access, email and similar programs, for their intended use on the university network. Scanning of the network, "packet sniffing", packet interception/copying/decryption and any other means of reading, altering, spoofing or otherwise monitoring and/or altering network communications is forbidden without specific approval in writing from both the Information Security Officer and Information Technology.
The university reserves the right to analyze network traffic at any time deemed necessary by either manual or automated means. For example, the university may specifically monitor network traffic if instructed by legal authorities; for assessing system integrity, performance, or management; or for possible policy violations. Network audit logs may record the following: packet origination, date/time, source and destination, path, protocol and port and/or other packet monitoring for suspicious activity.
The use of utility programs capable of overriding system and application controls is restricted to authorized technical support personnel.
Guest/Temporary Network Use
Limited guest (visitor) access via wired or wireless connection can be provided. Faculty, staff or administrator account sponsorship may be required. See ISO-007 User Accounts and Acceptable Use for more details.
The university's voice networking (Voice Over Internet Protocol - VoIP) provided by Information Technology is based on FCC standards and specifications. This consists of the telecommunications services, dial tones, telecommunications equipment, and specialized circuitry. All VoIP connections are maintained and provisioned by the IT Division.

ISO-012 Workstation and Computing Devices
ISO-013 Server Computing Devices
Information of a confidential or proprietary nature and other information that would not be routinely published for unrestricted public access or where disclosure is prohibited by laws, regulations, contractual agreements or University policy. This includes (but is not limited to) full name or first initial and last name and employee ID (in combination), identifiable medical and health records, grades and other enrollment information, credit card, bank account and other personal financial information, social security numbers, grant reviews, dates of birth (when combined with name, address and/or phone numbers), user IDs when combined with a password, etc. Sensitive information does not include personal information of a particular individual which that individual elects to reveal (such as via opt-in or opt-out mechanisms) (see Information Management and Classification Standard)
The use of software or other techniques to appear on the network as something other than reality (masquerading as something you are not). Example: The hacker tricked the system into allowing him onto the trusted network by spoofing the identity of a trusted server.
Policy Authority/Enforcement: The University's Information Security Officer (ISO) is responsible for the development, publication, modification and oversight of these policies and standards. The ISO works in conjunction with University Leadership, Information Technology, Audit Services and others for development, monitoring and enforcement of these policies and standards.
Policy Compliance: Failure to comply with these policies and standards and/or any related information security and/or information technology policy, standard or procedure may result in disciplinary action up to and including termination of employment, services or relationship with the University and/or action in accordance with local ordinances, state or federal laws.
This policy is subject to change or termination by the University at any time. This policy SUPERSEDES all prior policies, procedures or advisories pertaining to the same subject.
This policy will be reviewed annually to determine if the policy addresses University risk exposure and is in compliance with the applicable security regulations and University direction. In the event that significant regulatory changes occur, this policy will be reviewed and updated as needed per the Policy Management process.
