Network Group FROM: Student SUBJECT: Security and the OSI Model The Open Systems Interconnect (OSI) Model is the basis on which network communications function. Every network application more or less adheres to the standards of the OSI Model. Each layer of the OSI model represents a level of network functionality. For each layer‚ there are different types of security to protect the network at that layer. The physical layer is the actual medium in which the data travels. This is usually

4 OSI Transport Layer 4.1 Roles of transport Layer 4.1.1 Purpose The Transport layer provides for the segmentation of data and the control necessary to reassemble these pieces into the various communication streams. Its primary responsibilities to accomplish this are: Tracking the individual communication between applications on the source and destination hosts Segmenting data and managing each piece Reassembling the segments into streams of application data Identifying the different applications

Security and the OSI Model Network security is a topic that reaches far beyond the realm of firewalls‚ passwords‚ and user ID accounts. For a network and data to remain secure there must be protective measures at each level in the OSI interconnect model. While each layer basically operates autonomously of the other it is important to ensure that the data being transmitted from the host to destination has not been tampered with or is being prevented from reaching its destination. There are

Attacks on layer two of the OSI model Seven layers of OSI In 1977 a model called Open Systems Interconnection (OSI) was proposed‚ with the aim to establish an interoperability standard for different vendor products. This model defines several layers related to data transfer‚ from the lowest (physical) to the highest (application) layer. They have a strong dependence upon one another and headers are usually added when traversing from a lower layer to a higher one. The seven layers are: Layer 1 - Physical
