Programs that run independently between computers and across networks.  They Make use of all internet networking. Emails, file transfers. Hard to contain.

Encryption.  Combination of Public and Private Keys.  Public-known to everyone, Private-only by the receiving party.  This is Called Asymmetrical. Use private key to decrypt both pieces.

Symmetrical encryption.  More Secure.  Both are the only people with Encryption Key. You and receiver are the only one with decryption key. Problem is how you get the key securely. 

They assign the digital certificates. Verisign. They are the ones who validate the authenticity of a website. 

This is a broadcast message.  Another use is for the Access Control Lists (ACL). Used for any keyword. Blanket statement. Like delete *.* All encompassing.  

Virtual Private Network. Site to Site VPN. 1 location to another. Sits on edge of the LAN and establishes the connection between sites. VPN establishes a connection with another VPN on the other end.

Infrastructure as a service. Hardware services in the cloud and provide virtually. Such as servers, switches, etc. 

Payment Card Industry Data Security Standard.  A security standard for credit card data and transactions. Requires network segmentation. 

Temporal Control Integrity Protocol. Encryption protocol designed as an integrity check for WEP. Wirless Encrption Protcol rather than sophisticated security protocols.

Layer 3.  Where firewalls and IPSEC operate as well as IP, Internet. The packet movement work at this level. Not Frames. Emails. 

Password Authentication  Protocol. Authenticated information sent in Clear Text. No encryption. Authentication information is sent in CLEAR TEXT. Not encrypted. Worthless.

An attack in which hackers transmit bogus requests or connection to servers or applications in order to harvest usable information in order to guide the attack efforts. On the front door of servers. 

Reverse of Proxy. Outside world coming into company network Internal via proxy. Outside-Proxy_firewall. Outside world and come through box to one resource.  Don’t want everyone coming through the firewall. The server on the inside can’t trust everyone from the outside. Everyone is shielded on the inside. You can cache as well. Goes out and dumps website on server. Each web page has a TTL. Firewall trusts the Proxy and lets in it to the one resource. 

Security principal providing proof of delivery and Proof of senders Identification. Verifies we got it and were it came from. 

Type of virus that’s dormant till specific condition is met.  Change of a file or match in current time. Example: i.e. if word printed is yes.
