"Telephone number mapping is a system of unifying the international telephone number system of the public switched telephone network with the Internet addressing and identification name spaces. Internationally, telephone numbers are systematically organized by the E.164 standard, while the Internet uses the Domain Name System (DNS) for linking domain names to IP addresses and other resource information. Telephone number mapping systems provide facilities to determine applicable Internet communications servers responsible for servicing a given telephone number using DNS queries.
The most prominent facility for telephone number mapping is the E.164 Number Mapping (ENUM) standard. It uses special DNS record types to translate a telephone number into a Uniform Resource Identifier (URI) or IP address that can be used in Internet communications." [Telephone number mapping.

"There are two definitions for wireless LAN roaming:
Internal Roaming (1): The Mobile Station (MS) moves from one access point (AP) to another AP within a home network because the signal strength is too weak. An authentication server (RADIUS) performs the re-authentication of MS via 802.1x (e.g. with PEAP). The billing of QoS is in the home network. A Mobile Station roaming from one access point to another often interrupts the flow of data among the Mobile Station and an application connected to the network. The Mobile Station, for instance, periodically monitors the presence of alternative access points (ones that will provide a better connection). At some point, based on proprietary mechanisms, the Mobile Station decides to re-associate with an access point having a stronger wireless signal. The Mobile Station, however, may lose a connection with an access point before associating with another access point. In order to provide reliable connections with applications, the Mobile Station must generally include software that provides session persistence.
External Roaming (2): The MS (client) moves into a WLAN of another Wireless Internet Service Provider (WISP) and takes their services (Hotspot). The user can independently of his home network use another foreign network, if this is open for visitors. There must be special authentication and billing systems for mobile services in a foreign network." [Wireless LAN. Wikipedia]

"Neither company validated security certificates to make sure the app was sending the information to the right place. That left users vulnerable to “man in the middle attacks.” An attacker could trick the app into letting him access communications between the app and the online service. Neither the person using the app nor the online service would know the attacker was there." [consumer.ftc.gov/ blog/ how-secure-mobile-app]

"Network planning and design is an iterative process, encompassing topological design, network-synthesis, and network-realization, and is aimed at ensuring that a new telecommunications network or service meets the needs of the subscriber and operator. Network planning process involves three main steps: 1) Topological design: This stage involves determining where to place the components and how to connect them. 2) Network-synthesis: This stage involves determining the size of the components used, subject to performance criteria such as the Grade of Service (GoS). 3) Network realization: This stage involves determining how to meet capacity requirements, and ensure reliability within the network."

Virtual PBX systems or hosted PBX systems deliver PBX functionality as a service, available over the public switched telephone network (PSTN) or the Internet. Hosted PBXs are typically provided by a telephone company or service provider, using equipment located in the premises of a telephone exchange or the provider's data center. This means the customer does not need to buy or install PBX equipment. Generally the service is provided by a lease agreement and the provider can, in some configurations, use the same switching equipment to service multiple hosted PBX customers."

This example was designed on the base of the diagram from the "BYOD Guidance: BlackBerry Secure Work Space" on the website of the UK Communications Electronics Security Group (CESG).
"Secure Work Space (SWS) for iOS and Android is a containerisation, application-wrapping and secure connectivity option that delivers a higher level of control and security to iOS and Android devices, all managed through the BlackBerry Enterprise Service (BES) administration console.
Work space applications are secured and separated from personal applications and data. The work space applications include an integrated email, calendar, and contacts application, an enterprise-level secure browser, and a secure document viewing and editing application.
The work browser allows users to securely browse the organisation’s intranet and the Internet. If the device is lost or the employee leaves the organisation, you can chose to delete only corporate information or all information from the device.

Recommended network architecture
The walled garden architecture, shown below, aims to limit the impact of a compromise of an EUD and isolate high risk components from high value components where possible. The enterprise servers installed as part of SWS are high value resources that require suitable protection but are also high risk; they perform complex processing tasks that are more likely to contain exploitable vulnerabilities. These competing priorities make securely placing the servers into an existing network challenging, and organisations that wish to deviate from this architecture below should ensure they understand the risks of doing so."

"Network Mapping Software.
A number of software tools exist to design computer network diagrams / or generate visual maps of networks, servers, storage, services, data centers, and other peripherals. Broadly, there are two types of software tools - those that help create diagrams manually and those that generate them using automated / semi-automated approaches.
Type of Software.
(1) Manual - allows users to design and draw logical and physical topology diagrams by manually placing icons and connections.
(2) Automated - generate topology diagrams / maps by traversing the network and automatically discovering resident devices or by importing network data." [Comparison of network diagram software. Wikipedia]
