Glossary

The following defines some of the technical words and phrases used on this web site.

Dictionary Attack

A brute force way for guessing usernames and/or passwords.  A spammer uses dictionary attacks to guess e-mail addresses, while hackers use dictionary attacks to login to systems with weak passwords.

LAMP

LAMP is an acronym for Linux, Apache, MySQL and PHP.  These four technologies provide the necessary engine for delivering web applications, for example: wikis, online forums, content management, and others.

Mail Bomb

A flood of unwanted e-mail to a mail server.  Mail bombs are usually caused by spammers performing dictionary attacks, or from hackers attempting to slow down a server or annoy a particular e-mail recipient.

Open Source Software

Open source software grants the user the right to run, copy and modify source code for a given software program.  There is a common misconception that open source means the price of the software is zero.  The following definition from the Free Software Foundation clarifies the phrase:

Free software is a matter of liberty, not price.  To understand the concept, you should think of "free" as in free speech, not as in free beer.  Free software is a matter of the users' freedom to run, copy, distribute, study, change and improve the software. Detailed definition at the Free Software Foundation

Phishing

Phishing is an e-mail message and/or web site that masquerades as a legitimate request for personal information.  This type of fraud is typically used to lure people into providing sensitive personal information such as credit card numbers, banking information, and usernames/passwords.  eBay, PayPal and banking institutions are the most common organizations used for phishing attempts.

Product End-of-Life / End-of-Life

Software needs to be updated on a regular basis.  However, these updates do not last forever.  Every software release (for example, version 3.2) comes with a end-of-life: the date when software updates are no longer provided.  You can find the product end-of-life dates here.

Source Code

Source code is what developers write to create a software program.  This source code is then converted (compiled) from the human-readable format to machine-readable format.  Red Hat integrates hundreds of open source software programs to produce their Linux Advanced Server software.  In turn, ClarkConnect developers use Red Hat's source code to build the ClarkConnect server/gateway solution.

Mailboxes and Users

A user is defined as an account on the system.  A mailbox is a user with optional e-mail services enabled.  Mailboxes not only store mail messages, but also contacts, calendars, task and notes.

Example -- Consider a retail store with 30 part-time retail sales clerks and 10 full-time staff.  40 users are configured in all, but only the 10 full-time staff require e-mail.  The part-time staff only use their account to login for Internet access.
