A backdoor is a program through which unauthorized programmers can obtain access to secure areas of your system. Once the security has been bypassed, these programs can make changes to the operating system and the registry. Backdoors often are associated with Trojan horses. Hackers will place backdoors to gain re-entry easily after their initial attack.

secret passage through the security built into logiciel usually by the programmer(s) who wrote it ( language=modern cyber-slang); sometimes, when a program's security, as required by customer and/or specification, takes time and/or keystrokes, the programmers writing the code will build in a backdoor to make it easier and faster for them to run the program, like for testing. Used as a verb: to write such a backdoor; also, a way around the limitations of Einsteinian physics — see Backdoor Planets

A way to bypass the normal login security and gain control of a computer without necessarily obtaining the owner's consent. If a backdoor is installed on a network-attached computer, a person anywhere on the Internet may be able to gain control of the computer without your knowledge or approval. A backdoor need not have malicious intent; e.g. operating systems are sometimes shipped by the manufacturer with privileged accounts for use by field service technicians or the vendor's maintenance programmers. However, they may also be used for intrusion by unauthorized persons. Also known as a "trap door".

A piece of software that allows access to a computer without using the conventional security procedures (e.g. without knowledge of the user's password and user name). These programs are often Trojans.

harmful software that allows hackers inside your computer

An opening that programmers sometimes build into a program to allow them to update the program, fix bugs or monitor problems or usage. Backdoors can create serious security issues depending on the capabilities of the backdoor and if they are discovered and exploited by malicious people.

Also called a trapdoor. An undocumented way of gaining access to a program, online service or an entire computer system. The backdoor is written by the programmer who creates the code for the program. It is often only known by the programmer. A backdoor is a potential security risk.

A program which allows an unauthorized user to have access to a victim's computer. This is considered a hacker tool used to maintain control of a victim's computer.

Software installed without permission after a system is compromised; allows the attacker to access a compromised computer while easily avoiding security mechanisms.

A security hole that is designed to allow someone to connect to your computer and control it. Can be installed by a legitimate program's author, or by malware.

A program that provides hidden access to your computer.

a means of access to a computer program that bypasses security mechanisms. A programmer may sometimes install a back door so that the program can be accessed...

Programs including this feature allow malicious users to gain full access to remote systems.

An undocumented method of gaining entrance to a computer system. These are often placed in networks by programmers for easy troubleshooting, but hackers are especially good at sniffing them out.

An undocumented way of gaining access to a program, a computer system or network. The backdoor is usually implemented by the creator of the program, and is usually only known to him. A backdoor is a potential security risk.

A Backdoor is a program that enters the computer and creates a backdoor through which it is possible to control the affected system without the user noticing. A very popular tool with hackers

Programs that give an attacker access to and remote control of another computer. Backdoors are largely Trojans dealt with by most anti-virus products. NIPS (Network Intrusion Prevention System) helps detect and block backdoor communications.

A backdoor is a secret or invisible entry point that allows access to a computer system without the use of authentication.

This is the way a hacker enters a computer system even after all other security holes have been closed.

Backdoor is a name for a trojan horse program which opens security vulnerabilities to the system when executed.

A means of disabling a system's security which is deliberately left by designers of the system, often to give access to service technicians or maintenance programmers.

The possibility of making a draw that requires that you catch two more cards. A backdoor draw is usually not strong enough on its own to pull for as the odds against making your hand are high. A backdoor draw is much more valuable when combined with either a made hand such as top pair or a second draw.

Make a hand by catching on the to last cards

A draw requiring two or more rounds to fill. For example, catching two consecutive cards in two rounds of Seven-card stud or Texas Hold'em to fill a straight or flush. A hand made other than the hand the player intended to make. I started with four hearts hoping for a flush, but I backdoored two more kings and my trips won.

To make an unexpected good hand from the last 2 cards(turn and river) after the flop.

A draw that needs both the turn and river card to improve. The same as runner-runner.

Also known as runner runner this is when in holdem or omaha you catch the turn and river to make your hand. For example you have Ah 5h and you get a flop Kh Jc 5c, if the turn and river are both hearts you have made a backdoor flush.

a draw that requires two cards in a row to complete, e.g. having three of one suit on the flop in hold 'em means you have a backdoor flush draw: you will have a flush if two more of that suit come on the turn and the river.

When you catch the Turn and the River to make your drawing hand. Example: You have As- 7s. The Flop is Ad-6c-4s. Your bet is called. The Turn is Ts. Everyone checks. The River comes up Js. This means you have made a “backdoor” nut flush. (See also “Runner

Hitting a perfect turn and river card to make a drawing hand. For example, you have two clubs in your hand and there is only one club on the flop. You hit a club on the fourth card and another club on the fifth card to give you a flush.

A really enjoyable situation as a poker player this is where you have just made a very large hand but actually intended to hit some other hand. For example you were playing for 3 of a Kind but instead hit a Straight on the River. You would be said to have hit a “Backdoor Straight”.

Making a hand other than the one originally intended.

Making a hand other than the one intended on the turn and/or river.

Used to describe a hand made, when the intention was to make a completely different hand.

A term for a flush or straight that was made with one card from the flop and both the turn and river card.

not to make the hand that you intended, but to make another.

inadvertently making a different hand from the one originally being drawn to. Example: a player holding a six and a seven, looking at a flop showing a three, six, seven, could make a "backdoor straight" if the turn and river brought a four and a five

Catching both turn and river cards to make a hand, e.g. With two hearts on the flop, two more arrive by the river to make a ‘backdoor' flush.

Two cards in a row that make a hand. For example, spades on the turn and river that fill in a flush would be a backdoor flush.

Catching two cards in a row, on the turn and the river, to complete a hand

A hand that is completed with the last two board cards.

Making a hand unexpectedly. For example, holding a 6 and an 8 suited (seeking a flush draw), and flopping 4, 5, 7 unsuited to make a backdoor straight.

Making an unintended hand

Making a hand by catching both turn and river cards. Common usage is "catching a backdoor flush" or "backdoor straight".

To make a hand you didn't expect to make by catching 2 cards that you needed to complete the hand. (Ie. In Texas Holdem, if you have one spade and there are 2 on the flop and there are spades on both the turn and the river, then you have made a flush back door. (Also called Runner Runner)
