  • Tarleton State University (Tarleton) protects and monitors against the effects of denial-of-service events and employs the following controls to achieve the denial-of-service objective by: 
    • Having all Tarleton networks reside behind layers of network defense systems; 
    • Utilizing redundant internet connections to minimize the risk of denial-of-service attacks; 
    • Enabling network security systems (i.e., firewalls) that block inbound traffic requests that exceed a reasonable threshold within a given amount of time that provide alerts to network administration personnel of the incident; 
    • Designing locally hosted mission critical information resources that are accessible only from within the Tarleton network during periods of degraded network connectivity; and 
    • Having cloud-based mission-critical information resources served by redundant data centers to provide continuous access during degraded network connectivity.
