Securing the Everywhere Perimeter Iot, BYOD, and Cloud Have Fragmented the Traditional Network Perimeter
White Paper Securing the Everywhere Perimeter IoT, BYOD, and Cloud have fragmented the traditional network perimeter. This revolution necessitates a new approach that is comprehensive, pervasive, and automated. Businesses need an effective strategy to differentiate critical applications and confidential data, partition user and devices, establish policy boundaries, and reduce their exposure. Leveraging Extreme Networks technology, organizations can hide much of their network and protect those elements that remain visible. Borders are established that defend against unauthorized lateral movement, the attack profile is reduced, and highly effective breach isolation is delivered. This improves the effectiveness of anomaly scanning and the value of specialist security appliances. Redundant network configuration is rolled back, leaving an edge that is “clean” and protected from hacking. Businesses avoid many of the conventional hooks and tools that hackers seek to exploit. Additionally, flipping the convention of access-by-default, effective access control policy enforcement denies unauthorized connectivity. The Business Imperative As businesses undertake the digital transformation, the trends of cloud, mobility, and IoT converge. Organizations need to take a holistic approach to protecting critical systems and data, and important areas for attention are the ability to isolate traffic belonging to different applications, to reduce the network’s exposure and attack profile, and to dynamically control connectivity to network assets. In addition to all of the normal challenges and demands, businesses are also starting to experience IoT. This networking phenomenon sees unconventional embedded system devices appearing, seemingly from nowhere, requiring connectivity. WWW.EXTREMENETWORKS.COM 1 IoT is being positioned as the enabling technology for all manner of “Smart” initiatives.

Understanding CIDR Notation Used for IP Address Display on 2500 Series® Processors
Application Note 2500 Series® Programmable Automation Control System Understanding CIDR Notation Used for IP Address Display on 2500 Series® Processors Newer CTI products featuring Ethernet ports, such as the 2500 Series® processor, the 2500P-ECC1, and 2500P-ACP1, display the IP address of the product on the front panel multi-segment display. This information has proven very useful to most customers, facilitating the connection of browsers to obtain diagnostic data and providing visual confirmation of the operating IP address. Beginning with Version 8.02 of the 2500 Series® processor firmware, we’ve added the capability to display the subnet mask in CIDR notation. This gives users more complete information about the IP address setting to allow them to easily get connected. This application note shows how to interpret the CIDR notation displayed on the front of the processor. What is CIDR Notation? CIDR notation (Classless Inter-Domain Routing) is an alternate method of representing a subnet mask. It is simply a count of the number of network bits (bits that are set to 1) in the subnet mask. Subnet mask bits are explained in a following section. The CIDR number is typically preceded by a slash “/” and follows the IP address. For example, an IP address of 131.10.55.70 with a subnet mask of 255.0.0.0 (which has 8 network bits) would be represented as 131.10.55.70 /8. CIDR notation is more concise method for designating the subnet mask. Compared to Dotted Decimal notation, which represents the mask as four values, each representing the decimal value of an octet of the mask, the CIDR format represents the mask as a single value.

LAN Topologies
0390.book Page 13 Wednesday, November 14, 2001 3:28 PM C H A P T E R 2 LAN Topologies The application in use, such as multimedia, database updates, e-mail, or file and print sharing, generally determines the type of data transmission. LAN transmissions fit into one of three categories: • Unicast • Multicast • Broadcast Unicast With unicast transmissions, a single packet is sent from the source to a destination on a network. The source-node addresses the packet by using the network address of the destination node. The packet is then forwarded to the destination network and the network passes the packet to its final destination. Figure 2-1 is an example of a unicast network. Figure 2-1 Unicast Network Server Client Client Client 0390.book Page 14 Wednesday, November 14, 2001 3:28 PM 14 Chapter 2: LAN Topologies Multicast With a multicast transmission, a single data packet is copied and forwarded to a specific subset of nodes on the network. The source node addresses the packet by using a multicast address. For example, the TCP/IP suite uses 224.0.0.0 to 239.255.255.255. The packet is then sent to the network, which makes copies of the packet and sends a copy to each segment with a node that is part of the multicast address. Figure 2-2 is an example of a multicast network. Figure 2-2 Multicast Network Server Client Client Client Broadcast Broadcasts are found in LAN environments. Broadcasts do not traverse a WAN unless the Layer 3 edge-routing device is configured with a helper address (or the like) to direct these broadcasts to a specified network address.

1.2. OSI Model
1.2. OSI Model The OSI model classifies and organizes the tasks that hosts perform to prepare data for transport across the network. You should be familiar with the OSI model because it is the most widely used method for understanding and talking about network communications. However, remember that it is only a theoretical model that defines standards for programmers and network administrators, not a model of actual physical layers. Using the OSI model to discuss networking concepts has the following advantages: Provides a common language or reference point between network professionals Divides networking tasks into logical layers for easier comprehension Allows specialization of features at different levels Aids in troubleshooting Promotes standards interoperability between networks and devices Provides modularity in networking features (developers can change features without changing the entire approach) However, you must remember the following limitations of the OSI model: OSI layers are theoretical and do not actually perform real functions. Industry implementations rarely have a layer‐to‐layer correspondence with the OSI layers. Different protocols within the stack perform different functions that help send or receive the overall message. A particular protocol implementation may not represent every OSI layer (or may spread across multiple layers). To help remember the layer names of the OSI model, try the following mnemonic devices: Mnemonic Mnemonic Layer Name (Bottom to top) (Top to bottom) Layer 7 Application Away All Layer 6 Presentation Pizza People Layer 5 Session Sausage Seem Layer 4 Transport Throw To Layer 3 Network Not Need Layer 2 Data Link Do Data Layer 1 Physical Please Processing Have some fun and come up with your own mnemonic for the OSI model, but stick to just one so you don't get confused.

Collision & Broadcast Domain a Collision Domain Is a Section of A
Computer Networking & Communication 4th Class Arranged By: Dr.Ahmed Chalak Shakir Collision & Broadcast Domain A collision domain is a section of a network where data packets can collide with one another when being sent on a shared medium or through repeaters, particularly when using early versions of Ethernet. A network collision occurs when more than one device attempts to send a packet on a network segment at the same time. A broadcast domain is a logical division of a computer network, in which all nodes can reach each other by broadcast at the data link layer. LAYER 1 - PHYSICAL LAYER Devices - Hubs, Repeaters Collision Domain: As you might have studied both these devices just forward the data as it is to all the devices that are connected to them after attenuating it (making it stronger so that it travels more distance). All the devices fall in the SAME COLLISION DOMAIN because two or more devices might send the data at the same time even when we have CSMA/CD working. So, the data can collide and nullify each other that way no one gets nothing. Broadcast Domain: These devices don't use any type of addressing schemes to help them forward the data like MAC or IP addresses. So, if a PC A sends something for PC B and there are also C,D and E PC's connected to the hub then all the devices i.e. B,C,D and E would receive the data ( Only PC B accepts it while others drop it ). This is what is being in a single BROADCAST DOMAIN.

Broadcast Domain
Broadcast Domain A broadcast domain is a logical part of a network (a network segment) in which any network equipment can transmit data directly to other equipment or device without going through arouting device (assuming the devices share the same subnet and use the same gateway; also, they must be in the same VLAN). A more specific broadcast domain definition is the area of the computer network that consists of every single computer or network equipment that can be reached directly by sending a simple frame to the data link layer’s broadcast address. Details on Broadcast Domains While any layer 2 device is able to divide the collision domains, broadcast domains are only divided by layer 3 network devices such as routers or layer 3 switches. Frames are normally addressed to a specific destination device on the network. While all devices detect the frame transmission on the network, only the device to which the frame is addressed actually receives it. A special broadcast address consisting of all is used to send frames to all devices on the network. The VLAN (Virtual Local Area Network) technology can also create a so-called “virtual” broadcast domain. A network built with switching devices can see each network device as an independent system. These groups of independent systems can be joined into one broadcast domain, even if the computers are not physically connected to each other. This is very useful when administrating large networks where there is the need for better network management and control. How to Restrict the Broadcast Domain Since a broadcast domain is the area where broadcasts can be received, routers restrict broadcasts.

1. Data Link Layer (Layer 2) the Data Link Layer Provides a Means for Exchanging Data Over a Common Local Media
University of Babylon/College of Information Technology/ Information Network Dept. / First Class / Second Semester/ Subject : Network and Distributed System/ Lecture : 4 1. Data Link Layer (Layer 2) The Data Link layer provides a means for exchanging data over a common local media. The Data Link layer performs two basic services: • Allows the upper layers to access the media using techniques such as framing. Controls how data is placed onto the media and is received from the media using techniques such as media access control and error detection. The Data Link layer is responsible for the exchange of frames between nodes over the media of a physical network. It is important to understand the meaning of the words medium and media within the context of this chapter. Here, these words refer to the material that actually carries the signals representing the transmitted data. Media is the physical copper cable, optical fiber, or atmosphere through which the signals travel. In this chapter media does not refer to content programming such as audio, animation, television, and video as used when referring to digital content and multimedia. • A physical network is different from a logical network. Logical networks are defined at the Network layer by the arrangement of the hierarchical addressing scheme. Physical networks represent the interconnection of devices on a common media. Sometimes, a physical network is also referred to as a network segment. Lecturer : Ahmed M. Al-Saleh & Mouayad Najim Page 36 University of Babylon/College of Information Technology/ Information Network Dept. / First Class / Second Semester/ Subject : Network and Distributed System/ Lecture : 4 The description of a frame is a key element of each Data Link layer protocol.
