1.0 Introduction to Orange County IT Standards

This guide provides a framework for documenting policies, business processes, and internal controls used to effectively support the information technology (IT) resources of the government of Orange County, Florida, Board of County Commissioners (County). It explains the role of the County’s Information Systems and Services (ISS) personnel in approving, ordering, delivering, and maintaining IT services and products (hardware, software, networks, security, and other IT components) for employees throughout the County. It identifies County-approved products and procedures for acquiring IT systems and services. This guide also establishes County IT standards for use by third-party vendors providing externally hosted systems to various County departments.

The goal of ISS is to build an efficient, effective, and cost-efficient operation with an excellent return on investment by delivering new technologies and a state-of-the-art network server infrastructure. ISS provides prompt problem resolution through the customer service of its Help Desk. ISS seeks to maintain a diverse computing environment designed to meet the requirements of all County departments, while minimizing the risk of data loss or downtime. All computer hardware and software must be approved by ISS prior to purchase.

The ISS Department is comprised of 160+ employees, who are committed to its customer relationship-building attitude. ISS provides a business approach to serving all County agencies, which together form a partnership with ISS personnel to enhance productivity and service to the community.

The following standards apply to any device approved for connection to the County IT network or in use by County employees:

ISS personnel are responsible for ordering all new computers, software, servers, telephones, and mobile devices for use by County employees. Hardware and software orders arrive at the ISS Warehouse at 3517 Parkway Center Court, Orlando, FL 32808.

2 Submit orders by opening a ticket to request the new equipment or software using the ISS Support Center’s SupportCenter@ocfl.net email address. All purchase requests require approval in two forms.

Initial request approval is by the customer’s manager as indicated in the Peoplesoft “Reports To” field. Updates and Changes should be submitted through an ECN to HR. The secondary approval must come from a divisional representative with purchasing limit approvals. The emails will include pertinent information about the requested item(s). If sufficient details are not included in the initial email request, ISS staff will reach out to gather necessary information for the order. A list of authorized new products for purchase begins on the following page.

ISS Warehouse personnel are responsible for coordinating with the Comptroller’s Office staff to apply County asset inventory tags on computer components, as necessary, prior to installation of the equipment. No one but the Comptrollers staff an add or remove asset tags.

ISS Support personnel will install all operating systems and software. At the time of installation, ISS Support personnel must receive a copy of all installation software, along with written installation instructions, and licensing documentation. ISS will not install software without proof of licensing.

All installed computers must, at a minimum, have the following:

o ISS-installed anti-virus software o Computer configuration policy control for group management of devices by Active Directory o Remote access only as designated by ISS (ISS prohibits the use of Virtual Network Computing

[VNC] and Remote Desktop computing.)

o ISS-approved remote monitoring and management tools o Only ISS personnel shall have administrative rights.

o Hardware must be a standard supported model

ISS Enterprise Security is responsible for ISS video service; however, deployment of video equipment on the local government network must be discussed with staff members of the Data Network Team prior to purchase to determine compatibility, bandwidth, network equipment requirements, and installation feasibility.

6.0 Network Systems Requirements

6.1 Protocol Node Names and Addresses

The ONLY protocol allowed on the County Data Network is the Internet Protocol referred to as

Internet Protocol (IP) or Transmission Control Protocol/Internet Protocol (TCP/IP) Version4.

There can be only one unique address for each node on the network. Node naming and addressing conventions will conform to the guidelines established here.

The NOC assigns all addresses for all devices connecting to the County Network. All IP addresses must conform to R.F.C. 1918:

10.0.0.0 - 10.255.255.255/8

172.16.0.0 - 172.31.255.255/12

192.168.0.0 - 192.168.255.255/16

The NOC maintains an addressing plan and uses the plan to assign addresses. The Internet Addressing Authority, a private entity, assigned a block of addresses for the County. The NOC will maintain and assign these addresses, as needed.

Use of Registered Internet addresses on the County network is not allowed.

All network numbers for “special function” TCP/IP networks will be assigned by the NOC.

No INTERNET connections are allowed from any node, modem, or communications device on the network without NOC and Enterprise Security approval.

A network-wide, shared-use Internet connection is available to all entities.

TCP/IP DOMAIN NAME SERVERS (DNS) are an alternative to local administration and maintenance of a “hosts” file. Any Divisions, Elected Officials, or agencies wishing to use the DNS may send a list of IP addresses to be included in the DNS to the ISS Support Center, (407-836- 2929 or 6-2929), which will be routed to the NOC staff.

Entities who have dedicated network staff and wish to be assigned their own IP address space will request the assignment from the NOC through the ISS Support Center, (407-836-2929 or 6- 2929). These entities will provision their own DNS and be responsible for administration of their own IP address spaces (as assigned by the NOC for the agency to administer).

Only routed networks with at least 254 IP nodes are eligible for this option. DHCP is provided by the NOC.

No shared device (printer, server) may use a DHCP address. Static IP addresses are available in limited amounts on request.

6.2 Bridges, Routers, and Gateways

Routers are required at points in the network where traffic control and/or broadcast domain segmentation needs exist.

Routers are required on all Wide Area Network connections.

Protocol conversion is not supported on this network, as one common protocol (TCP/IP) is standard for all nodes.

6.3 Network Security

All default accounts on all processors connected to the network will either be disabled or have

P a g e | 13 the default password changed. No accounts are allowed without passwords.

The default “privileged password” on all network electronics will be changed.

All dial-up access must be provided through secure access servers. No direct access via dial-up lines is allowed on any type of device, processor, terminal, server, or PC connected to the network.

The NOC provides and maintains a secure access server for Dial-up use. Contact the ISS Support Center (407-836-2929 or 6-2929) for remote access authorization by the Enterprise Security Team.

The requesting department will provide the hardware & software for the employee’s homeuse, unless the employee provides their own.

Vendor field service will have remote access through NOC provided access servers. VPN access is available for use.

No entity on the network shall make any connection to the Internet, dial-up service, wireless provider, or wireless access-point without written permission from the ISS Enterprise Security Team and Network Operations.

An Internet gateway is provided for all entities on the network to use.

Any entity that directly connects their network to the Internet may not remain connected to the County network, due to security risks. If the Internet connected entity supplies, at their own expense, an acceptable Firewall between their networks and the County networks, the County network connection can resume via the Firewall provided.

Wireless Local Area Network (LAN) (Ethernet) Security All 802.11x wireless LANs must use a DOT1X supplicant for network admissioncontrol.

All 802.11x clients must use VPN triple Data Encryption Standard (DES) or Advanced Encryption Standard (AES) encryption. Client authentication via RADIUS server is required. The RADIUS server is provided and administered by ISS Enterprise Security.

All access points attached to the County network must be Lightweight Access Point (LWAP). (No stand-alone access points are permitted)

Wireless Wide Area Network (WAN) Security The County maintains a contract with a wireless provider. A gateway is available for connecting to the contracted wireless provider. The County prohibits access to the network using any other wireless provider.

6.4 Network Components

Transmission Media Fiber-optic, Category 5, 5e, and 6, and Category 3 Unshielded Twisted Pair (UTP), Shielded

Twisted Pair (STP), and radio (802.11x) are all permitted for IP data communications in the network.

Transmission Methods Optical, metallic cable, leased data circuits (analog, digital), private (analog, digital), and wireless

(802.11x) are all permitted for IP data communications in the network.

Supported LAN Types ETHERNET, 802.3, 10 BASE T, 100 BASE TX, 100 BASE FX, 1000 BASE xx (Gigabit), 802.11x

(wireless Ethernet), 10 GIGABIT.

Etherchannel: The only Etherchannel protocol supported by the County is 802.3ad Link

Aggregation Control Protocol (LACP).

6.5 Network Circuits

The NOC will design all WAN networks and, if required, procure leased data communications circuits from the Carrier.

The NOC will act as the central point of contact between all entities using WANcircuits.

P a g e | 14

The NOC will be notified by the affected entity and/or the ISS Support Center of service affecting WAN outages.

The ISS Support Center (407-836-2929 or 6-2929) and the NOC will be responsible for coordinating successful repair of WAN circuits.

The NOC will be responsible for ordering the disconnection and termination of leased data circuits upon notification by the customer.

Critical LANs and/or WANs may be designed with duplicate, automatic, redundant circuits and electronics to provide automatic recovery of data communications.

Circuits leased by any entity (other than the County) will be managed by that entity’s technical staff.

A Remote Site is available for recovery of certain critical applications and County networks in the event of a formally declared disaster.

6.6 Network Installation

In situations where installation of network equipment by one entity may affect customers from other entities, the installation will be jointly coordinated by representatives of the NOC and the other entities.

The NOC will design and install all LAN and WAN networks, except in specialcircumstance.

6.7 Network Trouble Reporting

Customers exclusively confined to applications delivered by networks supplied by the NOC will call or e-mail the ISS Support Center (407-836-2929 or 6-2929) to report trouble, request service, and get technical advice. The ISS Support Center will screen all calls, resolve any problems it is able to resolve with ISS Support Center staff, and refer unresolved network problems to the NOC.

Customers exclusively confined to applications on networks supplied by other entities will call that entity’s network staff to report trouble, request service, and get technical advice.

Customers on a mix of processors and networks supplied by the NOC and other entity’s processors and networks will call the ISS Support Center (407-836-2929 or 6-2929) to report trouble, request service, and get technical advice.

The NOC employs a variety of network management and troubleshooting tools and systems.

These network management systems are used by the NOC staff to test, troubleshoot, and diagnose all devices attached to the network.

All LAN equipment attached to the network must support Simple Network Management Protocol (SNMP) and/or SNMP-2. Remote Monitoring (RMON) is also allowed, but not instead of SNMP.

RMON is in addition to SNMP. Older equipment not supporting these standards will be phased out. The NOC is the only organization permitted to run SNMP on network equipment.

Network problems that can be repaired by the NOC will be scheduled in a repair queue. Repair priority is based on the severity of the problem and quantity of customers affected.

All devices attached to the network must have at least a minimum SNMP profile entered, consisting of the entity’s name, address, and technical support staff phones number(s). This will assist NOC staff in locating the network on which the equipment is located, when troubleshooting.

6.8 Network Performance Management

The NOC is responsible for monitoring all LAN and WAN performance. This includes all SNMP and RMON.

Only NOC staff members are allowed to run SNMP/RMON on network devices.

The NOC will redesign networks, which sustain traffic loads that adversely affect customer interactive response times and/or reliability.

The NOC will assist other entities with managing the performance of their networks as

P a g e | 15 requested.

6.9 Network Documentation

Each entity on the network will provide the NOC with a current diagram of network topology, equipment location, and configuration (including building address and floor location).

The NOC will provide a diagram of the network as well as tables and listings of all physical and logical components to any approved requesting entity.

Each entity on the network will provide on-going, updated information to the NOC reflecting components, circuits, and logical changes.

The NOC will add this information to its diagram and database, and will provide the revised network documents to all requesting entities.

7.0 IP Telephony Standards

The definition of IP telephony is telephones and a Private Branch Exchange (PBX) with an integral Ethernet Network Information Card (NIC) using the Internet Protocol to communicate.

7.1 Telecom Connectivity and Applications

Orange County owns the block of 407-836-xxxx and 407-254-xxxx phone number ranges. These numbers may not be ported, transferred, or forwarded to 3rd party vendors, or cloud service providers. To use these services, the cloud service provider must provide new phone numbers.

IP phones must derive their electrical power from the CAT-6/5e Ethernet cable. (POE type-1, 802.af standard)

Ethernet switches in the closets will be used to provide in-line DC power through CAT-6/5e patch panels.

All Ethernet electronics used in this configuration will have a UPS attached.

IP phones must operate in a separate subnet from the attached PC.

IP phone packets will be given the highest priority of all IP communications traffic on the LAN.

Other non-telephony applications will have their “IP Precedence” bit modified at the Ethernet switch to conform to this standard.

IP phone access to the network through the internet provider will use the ISS provided VPN services.

7.2 Unwanted Calls

Robocalls and SPAM - We have automated security systems which block callers listed in a national database of Robo dialers. Our systems also block repeat callers who exceed a threshold consistent with automated advertising systems. If you are getting unwanted solicitations from an automated system please email the ISS Service Center (supportcenter@ocfl.net) to report the issue. Provide the time and date of the call, the number calling, your 10-digit phone number, and what was heard on the call.

Harassing phone calls - Please report calls that are threatening in nature to the Orange County Sheriff's Office. They will want to know the time and date of the call, the number calling, your 10-digit phone number, and why the call was harassing in nature.

Nuisance calls - Our mission is to serve the citizens of Orange County and our employees with integrity, honesty, fairness and professionalism. We cannot block nuisance calls from upset citizens. In extreme cases, issuing a new phone number may be an option.
