Section: Information Technology
Policy Number: 927
Responsible Office: Information Technology
Effective Date: 5/1/19
Revised: 5/1/19

Policy Statement

This policy sets out guidance for implementing security measures for St. John’s University’s (St. John’s) network systems. The established rules for network protection enable IT Department to create and maintain a secure network for its IT infrastructure.

Scope and Applicability

This policy only applies to St. John's University Information Technology (IT) department. Therefore, all University information systems may not be covered by this policy. Adherence to this policy helps safeguard the confidentiality, integrity and availability of the University’s information assets, and protects the interest of the University, its customers, personnel and business partners.


The use of networks is an essential part of the day to day business of St. John’s. Networks not only connect many of the components of business processes together internally, but they also link the organization with its suppliers, customers, stakeholders and the outside world. But the fact that so much information runs through networks makes them a target for those who would try to steal that information and disrupt our business. Therefore, these networks need to be protected to ensure that the confidentiality, integrity and availability of St. John’s vital information is at all times secure.

St. John’s sets out appropriate security requirements to protect its information assets within its network and implements the following controls:

  • Network segregation
  • Perimeter security
  • Public/Untrusted networks
  • Network configurations
  • Firewalls and routers
  • Intrusion detection system & intrusion prevention system
  • Defined Roles & Responsibilities 
  • File-integrity monitoring
  • System hardening


The following are the definitions relevant to the policy:

  • Computing Resources: All University information processing resources including all University owned, licensed, or managed computing services, hardware, software, and use of the University network via physical or wireless connection regardless of the ownership of the computer or device connected to the network.
  • Institutional Data: All data owned or licensed by the University.
  • University Community: Includes faculty, administrators, staff, student workers, graduate/technical assistants, alumni, interns, guests or agents of the administration, external individuals and organizations accessing University network services, and other authorized users.


The University reserves the right to audit networks and systems on a periodic basis to ensure compliance with this policy. Instances of non-compliance must be presented to and reviewed and approved by the CIO, the Director of Information Security, or the equivalent officer(s).

All breaches of information security, actual or suspected, must be reported to, and investigated by the CIO and the Director of Information Security. 

Those who violate security policies, standards, or security procedures are subject to disciplinary action up to and including loss of computer access and appropriate disciplinary actions as determined by the University.
