All other IT Policies can be found at https://elpaso.ttuhsc.edu/it/policies/

POLICY/PROCEDURE:

Access is the physical or logical capability to view, interact with, or otherwise make use of information resources. 1

Access Point is a device that allows computers or workstations to access the wired network by using radio transmissions. An access point contains transmit and receive antennas instead of ports for access by multiple wireless clients. Similar to standard wired “hubs.” Access points are shared bandwidth devices.

Authentication is a mechanism employed to properly identify system users, processes acting on behalf of users, or devices, to validate the identities of those users, processes, or devices. The process of securing the identity of an individual based on a user account name and password.

Authorization is the process of assigning individuals the permission to read, write, or modify system objects or execute transactions based on their identity.

Availability is the security objective of ensuring timely and reliable access to and use of information.

Broadcast Messages are messages that are simultaneously sent out to multiple recipients.

Cable (also referred to as cable modem) is a type of Internet connection provided by the local cable company, used to transfer data at high speeds when compared to a dial-up modem.

Encryption (encrypt or encipher) – the conversion of plaintext information into a code or cipher text using a variable called a “key” and processing those items through a fixed algorithm to create the encrypted text that conceals the data’s original meaning.2

Enterprise Security Analyst (ESA) is an individual designated by the Information Technology Security Officer. ESA’s work alongside the TTUHSC El Paso Information Security Officer to implement security procedures, maintain locally administered security products, respond to security incidents, and coordinate the installation of patches on servers and workstations to correct security vulnerabilities.

Federal Educational Rights and Protection Act (FERPA) is a federal law that protects the privacy and confidentiality of student educational records.3 Firewalls are security systems which control and restrict both network connectivity and network services.

Firewalls establish a perimeter where access controls are enforced. Connectivity reflects which systems can exchange information. A service, sometimes called an application, refers to the way information flows through a firewall. Examples of services include FTP (file transfer protocol) and HTTP (web services).

Guideline is a recommended, non-mandatory control that helps support standards or serve as a reference when no applicable standard is in place.4

Information Owner is a person with statutory or operational authority for specified information or information resources.6

Information Security Officer (ISO) is the individual appointed by the president or their designee and is responsible for administering the Institutional information security program. Under the direction of the CIO, the Information Security Officer is TTUHSC El Paso’s primary internal and external point of contact for all Information Technology security matters.

Information Security Program consists of policies, standards, procedures, elements, structure, strategies, objectives, plans, metrics, reports, services, and resources that establish an information resources security function within an institution of higher education or state agency.7

Interference is the degradation of a communication signal, whether wired or wireless in origin, caused by electromagnetic radiation from another source. Such interference can distort, slow down, or completely eliminate the transmission of a communication signal, depending on the strength of the interference.
