Switch Security (2)-MAC address flooding

Mac layer Attack rumor address floodA common two-layer attack or switch attack is a Mac flood, with an intruder using a large number of invalid source MAC addresses, which can cause the switch's cam table to overflow, because the switch cannot find the port corresponding to the destination MAC address in the MAC address table, causing the switch to periodically flood the data frames to all other ports, The switch will no longer receive new legitimate

The artificial neural network was cleverly built, using a hive automaton structure designed to tailor a machine called cam brainmachine ("Cam brain Machine") to a client (CAM is the abbreviation for cellular automata machine). The man boasted that the artificial network machine would have the intelligence of a cat. Many neural network researchers think

source Facelets implementations, the JSF 2 Expert group also made changes to the underlying Facelets APIs, but retained a back-to compatibility with the tag library. This means that the existing views implemented with open source Facelets should apply to JSF 2.More information about Facelets's many features can be found in these two articles in Rick Hightower, "Facelets is perfect for JSF" and "Advanced Facelets programming." Tip 1: Follow th

Attacks and defense against common network devices

method:CAM table, also known as MAC Address Table) overflow. The MAC address table of each switch device has a capacity limit. Intruders send packets with different MAC addresses from the same port within a few seconds to fill the CAM table, as a result, the switch CAM table overflows, and normal CAM cannot be learned by the switch. Packets entering the vswitch

Three phases of data management development

how to do it to complete your command. For example, the programming languages we have learned: C and Pascal are both procedural languages. During programming in these languages, to print a piece of data, you must specify how to find the data, that is, specify its storage location or variable. Rather than procedural languages, the system can automatically complete your tasks by proposing "what to do" and not specifying how to do it. Relational Database language SQL is a non-procedural language.
