VOCABULARY

DMZ, can generate strong access rules between users and non-public servers and equipment published. Thus weaker rules only allow access to certain equipment and never to data, which will be after two levels of security.
 A FIREWALL (firewall) is a part of a system or network that is designed to block unauthorized access while permitting authorized communications.
 THE SPYWARE or spyware is software that gathers information from a computer and then transmits this information to a foreign entity without the knowledge or consent of the computer owner. The term spyware is also used more broadly to refer to other products that are not strictly spyware. These products perform different functions, such as displaying unsolicited advertisements (pop-up), collect private information, redirect requests for pages and installing dialers. 
WEP (Wired Equivalent Privacy ) was the first encryption protocol introduced into the first IEEE 802.11 standard back in 1999 .
 IEEE 802.1X and EAP The IEEE 802.1X authentication protocol (also known as Port-Based Network Access Control) is a framework originally developed for wired networks, and has mechanisms for authentication, authorization and key distribution and also incorporates access controls for users to join the network
. TMK (Temporary Key MIC - 2x64 bits) : Password for authentication data ( used only by Michael with TKIP ) . It uses a key dedicated to each side of the communication.
  KCK ( Key Confirmation Key - 128 bits) : Password for authentication Message ( MIC ) at the 4 - Way Handshake and Group Key Handshake .
  • KEK ( Key Encryption Key - 128 bits ): Key to ensure confidentiality data for the 4-Way Handshake and Group Key Handshake .
 • TK (Temporary Key - 128 bits): Data encryption key (used by TKIP or CCMP ). The PMK itself is not used never for encryption or verification integrity . On the contrary, is used to generate a key temporal encryption. AP - Access Point, Access Point , a base station Wi - Fi network that connects wireless clients to each other and networks cable .

 • GTK - Group Transient Key , key derived from GMK .
 • ICV - Integrity Check Value , field data combined with the data text for the integrity (based on weak algorithm CRC32 ) .
 • IV - Initialization Vector, initialization vector , Overlays in the encryption key to produce a flow of unique key .
 • KCK - Key Confirmation Key, which protects integrity key handshake messages .
 • KEK - Key Encryption Key, key confidentiality protects the handshake messages .
 • MIC - Message Integrity Code , data field, joined the text data integrity ( in the algorithm basdo Michael ) . • MK - Master Key, primary key known by the supplican and the authenticator after 802.1x authentication process.
 MPDU - Mac Protocol Data Unit , data packet before fragmentation.
• MSDU - Mac Service Data Unit , data packet after fragmentation.
