2.3 Plan Phase: the IT Security Team will review the firewall zone build request and schedule an initial meeting with the University departmental contact provided in the request. A Port Inventory Form—intended to identify both network ports as well as computer systems that will be migrated behind the new firewall zone—will be sent to the departmental contact for listing all computing assets that will be protected by the firewall. The Port Inventory Form must be fully completed by the individual department and returned to the IT Security Team one week prior to the initial meeting. Firewall zone design will not commence until the Port Inventory Form is complete; this is to ensure that information is accurate and that the number of systems can be accurately ascertained in order to assign an appropriate new IP address range for systems moving into the new zone. 2.4 Design Phase: at the initial meeting, the Security Team will review the firewall zone build request, Port Inventory Form, and a preliminary design with the University departmental contact and any other appropriate team members. The IT Security Team will create a firewall zone diagram using CSSD’s firewall zone diagram template prior to the initial meeting. The University department will also identify a primary authorized contact and a secondary authorized contact for handling any issues with the request and its implementation. The final proposed firewall configuration will be reviewed by CSSD’s IT Security Team and Network Engineering Team. Any changes will be communicated to the University departmental contact in writing.

SECURITY PROCEDURE Firewalls 2.5 Build Phase: Upon approval of the final firewall configuration by CSSD and the University department, CSSD will install and configure the firewall zones for the University department. The IT Security Team will submit a Help Desk ticket to request the firewall build be started; this ticket will be escalated to CSSD’s Network Engineering team for them to complete the firewall zone build. The Network Engineering team will also be responsible for creating VLANs, reserving IP address space, and any additional routing or switch work needed to complete the firewall zone build. 2.6 Migrate Phase: Upon completion of the firewall zone build, CSSD will assist the University department with migration of several test workstations behind the firewall. During the test period, firewall rule-sets may be made during business working hours. Once testing has concluded, all firewall ruleset changes must be made in accordance with the CSSD Change Management policy, as the zone is now considered to be production. Departments are responsible for testing systems once they have been migrated to the new firewall zone to ensure network connectivity has been maintained.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
