Network Security Diagram

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."

"Computer security, also known as cybersecurity or IT security, is the protection of information systems from theft or damage to the hardware, the software, and to the information on them, as well as from disruption or misdirection of the services they provide. It includes controlling physical access to the hardware, as well as protecting against harm that may come via network access, data and code injection, and due to malpractice by operators, whether intentional, accidental, or due to them being tricked into deviating from secure procedures."

"In computing, a firewall is a network security system that monitors and controls the incoming and outgoing network traffic based on predetermined security rules. A firewall typically establishes a barrier between a trusted, secure internal network and another outside network, such as the Internet, that is assumed to not be secure or trusted. Firewalls are often categorized as either network firewalls or host-based firewalls. Network firewalls are a software appliance running on general purpose hardware or hardware-based firewall computer appliances that filter traffic between two or more networks. Host-based firewalls provide a layer of software on one host that controls network traffic in and out of that single machine. Firewall appliances may also offer other functionality to the internal network they protect such as acting as a DHCP or VPN server for that network." [Firewall (computing). Wikipedia]

"A computer worm is a standalone malware computer program that replicates itself in order to spread to other computers. Often, it uses a computer network to spread itself, relying on security failures on the target computer to access it. Unlike a computer virus, it does not need to attach itself to an existing program. Worms almost always cause at least some harm to the network, even if only by consuming bandwidth, whereas viruses almost always corrupt or modify files on a targeted computer." [Computer worm.
