Body
Summary
This article contains information regarding Tenable Nessus agent hosts, including an outline of data elements collected by Tenable Nessus agents, and serves as a privacy policy and justification for deployment. This article is for users and administrators of servers or endpoints that store, process, or transmit sensitive or restricted information.
Content
USNH systems regularly store, process, or transmit sensitive information. This information is necessary for the institution to identify and enroll students, keep track of their health records, accept payment for services, and conduct research for both private and public entities. It is the responsibility of all USNH employees to act as stewards for the information entrusted to them. The USNH Networking and Cybersecurity department provides cybersecurity services for all USNH institutions with the goal to protect the data, systems, and services that USNH provides.
In computing, a software vulnerability is a weakness that can be exploited by a malicious party to gain access to data, systems, or privileges to which that malicious party is not entitled. This unlawful access to computing systems or data can lead to severe consequences for USNH. The consequences can be monetary, in the form of fines from regulating bodies. USNH might also face additional legal and monetary risk from litigation from damaged parties. Consequences can also be reputational, where the reputation of USNH as a responsible steward of research data, personally identifiable information (PII), health care information, or other sensitive information is damaged.
Given the amount and nature of the data stored, processed, or transmitted at USNH, it is necessary for USNH to maintain a vulnerability management program. This program is designed to limit the risk of software vulnerabilities by detecting and reporting on them so that appropriate mitigation can occur.
