Service Summary

ITS is committed to providing a secure platform for Mason computers and users in a dynamic and fluid computing environment.  ITS employs several measures and tools to prevent unauthorized people or applications from accessing the Mason network and computers connected to them, assets, and data, ensuring the integrity, accessibility, and confidentiality of the networks and data.

Service Offerings

Cisco Umbrella

Cisco Umbrella is a cloud-based tool that protects Mason users by blocking them from visiting websites that threaten to compromise Mason’s technology resources or defraud users.

Cisco Umbrella blocks users from accessing malicious websites. It will block users from sites where malware, ransomware, phishing, and botnets are present. Umbrella will redirect users from sites where cyber threats are present to a page explaining to users the site is malicious.

Firewall

The Mason network uses firewalls to protect university systems against unauthorized access and malicious attacks. Firewall security configuration is adjusted to accommodate university business. Firewall changes are generally made in the context of IT projects, but may be independently requested to accommodate the addition, change, or removal of public-facing systems, services, or applications.

All servers or other systems that offer public-facing services or applications connected to the Mason network must be registered with Information Technology Services. Access to secure services and applications is limited to authorized users only.

  • Firewall changes may be requested to accommodate the addition, change, or removal of public-facing systems, services, or applications
  • All servers or other systems that offer public-facing services or applications connected to the Mason network must be registered with ITS

Network Vulnerability Scanning

The network vulnerability scanning application, managed by the IT Security Office (ITSO), is a full-featured solution that allows for scanning of systems by authorized system administrators. Scans can be conducted either from behind or in front of university network firewalls and from networks that appear to be from outside the university LAN. The application provides for delegation of scanning, alerting, and reporting.

System Administrators are given accounts with limited rights that allow them to scan, see alerts, and access reports for their systems. System owners need to approve account requests, which should be accompanied by a list of systems to be scanned.

Report an IT Security Incident

The IT Security Office (ITSO) will assist faculty, staff, students, and alumni with containment, mitigation, and remediation of IT security incidents caused by:

  • an attempted or actual unauthorized use, disclosure, modification, or destruction of information
  • interference with information technology operation
  • a violation of campus policy, laws, or regulations

An IT security incident is considered serious if the entire Mason campus is impacted by one or more of the following:

  • Active threats
  • Potential unauthorized disclosure of sensitive information
  • Serious legal consequences
  • Severe disruption to critical services
  • Widespread and likely to raise public interest

You may have an IT security incident if:

  • the internet or your computer is unusually slow
  • there are signs of obvious tampering with your computer and/or devices
  • you are locked out of your user accounts
  • or, your computer and/or devices were lost or stolen

If a compromised system contains sensitive data:

  • Immediately report the incident
  • Do not attempt to investigate or remediate the compromise yourself
  • Do not power down the machine
  • Instruct any users to stop work on the system immediately
  • Remove the system from the network by unplugging the network cable or disconnecting it from the wireless network
