Public key The key from the public key cryptography key pair set that is designed to be sent out into the public. Anyone can obtain a persons public key and use it for secure comm. w/ that person. Public key is derived from the private key, but it can't be reversed.
Pretty Good Privacy (PGP) Can be used to encrypt and digitally sign e-mails. It's a public-private key system that uses a variety of encryption algorithms to encrypt files and mail. Not a standard, but is an independently developed product that has internet grass-roots support

X.500 The international Telecommunications Union(ITU) standard for directory Services in the later 1980's
A Signed Java Applet A java applet that has been signed by a trusted authority/company. A signed java Applet can have escalated permission access, possibly even out of the sandbox environment.
ActiveX Components A microsoft technology that allows customized controls, icons, to the features to increase the usability of the web-enabled systems
Discretionary Access Control A Method of restricting access to objects based on the identity of the subjects or the groups to which they belong.
Mandatory Acess Control (MAC) A security policy where labels identify sensitivity of objects, the label is checked to see if access should be allowed. "Mandatory" since labels are applied to all data automatically. Unlike "Discretionary" where the user to chooses label the data or not
Role Based Access Control (RBAC) A type of control where the levels of security closely follow the structure of an organization. The role the person plays in the organization corresponds to the level of security access they have to data
Cookies A plaintext file stored on your machine that contains information about you (and your preferences) and is used by a database server.
Asymmetric Encryption in which two keys must be used. One key is used to encrypt data and the other is needed to decrypt the data. Asymmetric encryption is the opposite of symmetric encryption where a single key is used both for encrypting and decrypting
Buffer Overflow Attack A type of Denial of Service Attack (DoS Attack) that occurs when more data is put into a buffer than it can hold. Thereby overflowing it.
SQL Injection Attack Using unexpected input to a web application. However, instead of using this input to attempt to fool a user, SQL injection attacks use it to gain unauthorized to an underlying database.
Cross Site Scripting Attack A form of malicious code injection attack where an attacker is able to compromise a web server and inject their own malicious code into the content sent to other visitors.
Promiscuous A mode where a network interface card (NIC) intercepts all traffic crossing the network and not just the traffic intended for it.
SYN Flooding A DoS attack in which the hacker sends a barrage of spoofed SYN packets. The receiving station tries to respond to each SYN request for a connection, tying up all the resources. All incoming connections are rejected.
ICMP An attack that occurs by triggering a response from the internet control message protocol (ICMP) Whit it responds to a seemingly legitimate maintenance request.

Mean-Time-Between-Failures (MTBF) The measure of the anticipated incidence of failure of a system or component
Service Level Agreement (SLA) An agreement that specifies performance requirements for a vendor. This agreement may use mean time before failure (MTBF) and Mean Time To Repair (MTTR) as performance measurements in the SLA.
