1. Out-of-brand Management -   a function of marketing that uses techniques to increase the perceived value of a product line or brand over time
2. Peer-to-Peer - denoting or relating to computer networks in which each computer can act as a server for the others, allowing shared access to files and peripherals without the need for a central server
3. Point-To-Point Tunneling Protocol (PPTP) -  an obsolete method for implementing virtual private networks. PPTP has many well known security issues. PPTP uses a TCP control channel and a Generic Routing Encapsulation tunnel to encapsulate PPP packets. Many modern VPNs use various forms of UDP for this same functionality
4. Port Authentication -enables configuration of parameters for each port
5. Port Mirroring - also known as SPAN (Switched Port Analyzer), is a method of monitoring network traffic. With port mirroring enabled, the switch sends a copy of all network packets seen on one port (or an entire VLAN) to another port, where the packet can be analyzed
6. Proxy Server - sits in between clients and external servers, essentially pocketing the requests from the clients for server resources and making those requests itself
7. Quality of Service (QoS) - the description or measurement of the overall performance of a service, such as a telephony or computer network or a cloud computing service, particularly the performance seen by the users of the network
8. Reverse Proxy Server – acts on behalf of the servers
9. Routing and Remote Access Service (RRAS) - a Microsoft API and server software that makes it possible to create applications to administer the routing and remote access service capabilities of the operating system, to function as a network router. Developers can also use RRAS to implement routing protocols
10. Site-to-Site - a type of VPN connection that is created between two separate locations. It provides the ability to connect geographically separate locations or networks, usually over the public Internet connection or a WAN connection
11. SSL VPN – Secure Sockets Layer Virtual Private Network
12. Traffic Shaping - bandwidth management technique that delays the flow of certain types of network packets in order to ensure network performance for higher priority applications
13. Trunk Port – a port or switch configured to carry all traffic
14. Trunking – process of transferring VLAN traffic between two or more switches
15. Virtual Local Area Network (VLAN) – segments networks using owned switches
16. Virtual Private Network (VPN) -
17. VLAN Trunking Protocol (VTP)

1. 802.1x: A port-authentication network access control mechanism for networks.
2. access control list (ACL): A clearly defined list of permissions that specifies what actions an authenticated user may perform on a shared resource.
3. Advanced Encryption Standard (AES): A block cipher created in the late 1990s that uses a 128-bit block size and a 128-, 192-, or 256-bit key size. Practically uncrackable.
4. Algorithm: A set of rules for solving a problem in a given number of steps.
5. asymmetric-key algorithm: An encryption method in which the key used to encrypt a a message and the key used to decrypt it are different, or asymmetrical.
6. Authentication: A process that proves good data traffic truly came from where it says it originated by verifying the sending and receiving users and computers.
7. Authenticating, Authorization, and Accounting (AAA): A security philosophy wherein a computer trying to connect to a network must first present some form of credential in order to be authenticated and then must have limitable permissions within the network.
8. Authentication Server (AS): In Kerberos, a system that hands out Ticket-Granting Tickets to clients after comparing the client hash to it's own. Also known as Ticket Granting Ticket.
9. Authorization: A step in the AAA philosophy during which a client's permissions are decided upon.
10. block Cipher: An encryption algorithm in which data is encrypted in "chunks" of a certain length at a time. Popular in wired networks.
11. Certificate: A public encryption key signed with the digital signature from a trusted third party called a Certificate Authority (CA), which is used to validate the identity of its holder when that person or company sends data to other parties.
12. Challenge Handshake Authentication Protocol (CHAP): A remote access authentication protocol in which the serving system challenges the remote client, which must provide an encrypted password.
13. Cipher: A series of complex and hard-to-reverse mathematics run on a string of ones and zeroes in order to make a new set of seemingly meaningless ones and zeroes.
14. Ciphertext: The output when cleartext is run through a cipher algorithm using a key.
15. Cleartext: Unencrypted data in an accessible format that can be read without special utilities. Also known as plaintext.
16. Data Encryption Standard (DES): A symmetric-key algorithm develovoped by the US Government in the 1970s and formerly in use in a variety of TCP/IP applications, in which it uses a 64-bit block and a 56-bit key.
17. digital signature: An encrypted hash of a private encryption key that verifies a sender's identity to those who receive encrypted data or messages.
18. Discretionary Access Control (DAC): Authorization method based on the idea that there is an owner of a resource who may at his or her discretion, assign access to that resource.
