One of the major shared resources of the University is its data network. The University's ability to conduct its business is dependent on reliable, stable access to the network and through the network to the Internet. University network and Internet connectivity can be jeopardized by computers/workstations, servers, and other devices that are not adequately protected from attack. Protection is optimized only when principal users maintain the operating systems of their devices, install, continuously run and regularly update antivirus software - when applicable, and apply patches that close known security breaches as soon as they become available.
Compromised or vulnerable devices connected to the University network present potential harm to the network, to other devices on the network, to other networks and the devices attached to them, and to the overall standing of the University's information technology enterprise. Delays in responding to compromised devices could result in losses of data and productivity, other operational problems, legal consequences, and harm to the University's reputation. Consequently, it is imperative that a compromised device be secured in order to eliminate the risk it poses. If a compromised device is being actively used in a way that threatens the integrity of the University network or other devices on the University network, it may be necessary to disconnect it temporarily from the network and secure it before it is reconnected. Because vulnerable devices may at any time be compromised, they must be remediated expeditiously.
A principal user who connects a device to the University network is responsible for working with appropriate staff to secure the device against compromise. Specifically, any device connected to the University network must (when applicable):
Further, it is highly recommended that firewalls be installed and run continuously on devices whenever possible and practicable.
Principal users who fail to fulfill the foregoing responsibilities are subject to the actions described in the following sections.
This policy applies to all University data regardless of its medium and/or form, and to all those who handle University information (faculty, staff, students, third party contractors, and any others).
A principal user who connects a device to the University network is responsible for working with appropriate staff to secure the device against compromise as soon as actions to address known vulnerabilities are identified. If a device is compromised, the principal user is responsible for working with appropriate staff to ensure that collateral risks or damage to the information technology infrastructure of the University, other devices on the University network, and other Internet-connected devices and networks around the world are prevented or minimized.
A compromised device, as specified in definition 3 below, should be immediately secured, shut down, or disconnected from the University network by the principal user. The principal user is responsible for initiating or cooperating with efforts to secure the device. The principal user is also responsible for initiating or cooperating with efforts to identify and notify other principal users whose devices may have been affected. Principal users who reconnect disconnected devices that they know are compromised and have not yet been secured are in violation of University policies and are subject to further actions and, possibly, sanctions.
As a last resort, in the cases of compromised devices connected to the University network as specified in definitions 5.i. and 5.ii. below, when time constraints permit no other course of action or when a principal user is unavailable or uncooperative, it may be necessary to suspend temporarily the network connection of the compromised device. This action should be taken, preferably, by the IT service organization responsible for supporting the principal user in question.
When a campus computer is actively attempting to compromise the integrity and or availability of UB's IT infrastructure, it will be disconnected from the network immediately and the owner and/or IT support staff will be notified of the problem and the protective actions taken.
As a last resort in the cases of compromised devices connected to the University network as specified in 5.iii., 5.iv., 5.v., and 5.vi. below, when time constraints permit no other course of action or when a principal user is unavailable or uncooperative, it may be necessary for CIT to suspend temporarily the principal user's UBIT account. This action should be taken, preferably, only after the principal user and (when applicable) the IT service organization responsible for supporting the principal user in question have been notified. When a principal user who is a faculty or staff member cannot be notified prior to this action or is unresponsive or uncooperative, every reasonable effort will be made to communicate with (in ascending order): the affected department chair or head, the affected Dean or Vice President, or the CIO. In such an event, the parties who would normally be consulted should be notified of the suspension as soon as possible after the action is taken.
Such temporary disconnections and suspensions should be imposed only until such time as the precipitating problem has been redressed. When a principal user who is a faculty or staff member cannot be notified prior to this action or is unresponsive or uncooperative, every reasonable effort will be made to communicate with (in ascending order): the affected department chair or head, the affected Dean or Vice President, or the CIO. In such an event, the parties who would normally be consulted should be notified of the disconnection or suspension as soon as possible after the action is taken.
Principal users are strongly encouraged to seek the advice of an IT support professional before reconnecting a previously disconnected or suspended device. If such a device is reconnected to the network and has not been secured, further action may be necessary to ensure that the device is properly secured.
Disconnection or suspension is considered a course of action to be avoided whenever possible and to be taken only when deemed necessary in the measured professional opinion of responsible parties in the Office of the CIO, CIT, or the IT service organization responsible for supporting the principal user in question. Within a reasonable time after the disconnection or suspension is imposed, a post-mortem analysis of the sequence of events leading to the suspension should be conducted. All affected or interested parties should be invited to participate in the post-mortem. The primary purpose of the post-mortem should be to determine - without recrimination - whether the suspension was justified by the facts and whether alternative, equally effective actions could have been taken.
The Chief Information Officer or his designee will periodically
review and update this policy as needed. Questions concerning this
policy should be directed to the Office of the Associate VP for
Violations of this policy will result in appropriate
disciplinary measures in accordance with University policies,
applicable collective bargaining agreements, and state and federal
