Anti-Spoofing Policy

Version 1.3

For Students, Faculty, Staff, Guests, Alumni


The purpose of this security policy is to ensure that anti-spoofing measures are in place to detect and block forged source IP addresses from entering University networks.


This IT security policy, and all policies referenced herein, shall apply to all members of the University community, including faculty, students, administrators, staff, alumni, authorized guests, delegates, and independent contractors (the "User(s)" or "you") who use, access, or otherwise employ, locally or remotely, the University's IT Resources, whether individually controlled, shared, stand-alone, or networked.

Policy Statement

You must configure network devices to reject packets originating from non-University networks that claim to originate from within Fordham University's owned and managed networks.


IT Resources include computing, networking, communications, application, and telecommunications systems, infrastructure, hardware, software, data, databases, personnel, procedures, physical facilities, cloud-based vendors, Software as a Service (SaaS) vendors, and related materials and services.

Spoofing is a technique used by an intruder to gain unauthorized access to IT Resources. The intruder attempts to infiltrate a network by posing as an internal, trusted source.
