With respect to the C.I.A. and A.A.A. concepts, what risks are posed by trojan horses?

Answer 1

Trojan Horses are malwares, it is a program designed to breach the security of a computer system while apparently performing some innocuous function.

So, Trojan horses in CIA for Confidentiality, Integrity and Availability is: -

• Trojan Horses do not maintain Confidentiality, as it does not require permissions and disclose information.
• Trojan Horses do not provide Integrity, Trojans can alter the data or even delete it.
• Trojan Horses do not affect the Availability of a data, a Trojan cannot allow an unauthorized access to a given data.

Trojan Horses for AAA is as follows: -

• Assurance cannot change the assurance of a Computer System, so Assurance is not affected by Trojans.
• Yes, Trojan Horses can affect the Authenticity, and take permissions to change the system settings.
• Trojans also affect the Anonymity of a system and can change the records of a data.

Trojans are viruses which enter a system and are designed so well, that they go unidentified. They do not appear to be harmful but they are.

Trojan will generally have unlimited access. It can do anything depending on the Intensions of the Attacker.

This is all for the risks associated by Trojan Horses.
