What are Logic Bombs,Trojan horses and Trap Doors?There are numerous kinds of malicious code in the worldtoday.
Despite the fact that they are just a little subset of these, logicbombs, Trojan horses, and trap doors are common. When an event is occurred, asmall program or a part of it is triggered by the event. These programs arecalled logic bombs and the eventsthat might use these programs are removal of a file or certain percentage ofdisk is filled etc., Generally the logic bombs are installed by insiders who hasaccess to the systems.
Trojan horsesare the programs that needs to be executed or installed by the users for themto be effective. There are generally included in entertaining stuff like games,linux packages etc., When the are effective, they perform tasks which user doesnot intend to do like replacing important files with malicious files or openinga malicious application when clicked on a game etc., And the last one of thesemalicious code attacks can be done through Trapdoors which are bits of code inserted in a program to quickly gain access atlater time which is general used by developers for testing or debugging. Butwhen the developers forget to remove these codes, that leads to a securitybreach which can lead hackers to access the systems.
Ways to prevent fromthem?As Logic Bombs, Trap Doors are the programs that aregenerally triggered and installed by an insider who has access to the systemwith detail knowledge of the system. So hiring right people does solve someamount of breach for these malicious code attacks. And also we can run Network Surveillance,Integrity Checking software’s and monitor programs to detect attempts to createlogic bombs and trap doors. Every company should follow accurate and well-developedSoftware development policies and procedures that can make effort for detectinglogic bombs and can make hard for people to plant them.
