Bump-in-the-wire

	Bump-in-the-wire Bump-in-the-wire (BITW) is a class of communications devices which can be inserted into existing (legacy) systems to enhance the integrity, confidentiality, or reliability of communications across an existing logical link without altering the communications endpoints. The term was originally used to indicate that the device should introduce only a relatively small increased latency in communications compared to the original, unsecured, approach. An example of such a device might be a security appliance which applies IPsec protection to communications between existing devices which themselves lack IPsec implementation protocol stack. Such a device might also be called a security gateway or could be implemented as part of a network firewall to implement a tunneling protocol In computer networks, a tunneling protocol is a communication protocol which allows for the movement of data from one network to another. It involves allowing private network communications to be sent across a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	IPsec In computing, Internet Protocol Security (IPsec) is a secure network protocol suite that authenticates and encrypts packets of data to provide secure encrypted communication between two computers over an Internet Protocol network. It is used in virtual private networks (VPNs). IPsec includes protocols for establishing mutual authentication between agents at the beginning of a session and negotiation of cryptographic keys to use during the session. IPsec can protect data flows between a pair of hosts (''host-to-host''), between a pair of security gateways (''network-to-network''), or between a security gateway and a host (''network-to-host''). IPsec uses cryptographic security services to protect communications over Internet Protocol (IP) networks. It supports network-level peer authentication, data origin authentication, data integrity, data confidentiality (encryption), and replay protection (protection from replay attacks). The initial IPv4 suite was developed with few secur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Security Appliance A security appliance is any form of server appliance that is designed to protect computer networks from unwanted traffic. Types of Security Appliances * Active devices block unwanted traffic. Examples of such devices are firewalls, anti virus scanning devices, and content filtering devices. * Passive devices detect and report on unwanted traffic, such as intrusion detection appliances. * Preventative devices scan networks and identify potential security problems (such as penetration testing and vulnerability assessment appliances). * Unified Threat Management (UTM) appliances combine features together into one system, such as some firewalls, content filtering, web caching A Web cache (or HTTP cache) is a system for optimizing the World Wide Web. It is implemented both client-side and server-side. The caching of multimedias and other files can result in less overall delay when browsing the Web. Parts of the syste ... etc. References Server appliance {{compu-network-s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Tunneling Protocol In computer networks, a tunneling protocol is a communication protocol which allows for the movement of data from one network to another. It involves allowing private network communications to be sent across a public network (such as the Internet) through a process called encapsulation. Because tunneling involves repackaging the traffic data into a different form, perhaps with encryption as standard, it can hide the nature of the traffic that is run through a tunnel. The tunneling protocol works by using the data portion of a packet (the payload) to carry the packets that actually provide the service. Tunneling uses a layered protocol model such as those of the OSI or TCP/IP protocol suite, but usually violates the layering when using the payload to carry a service not normally provided by the network. Typically, the delivery protocol operates at an equal or higher level in the layered model than the payload protocol. Uses A tunneling protocol may, for example, allow a foreig ...
