Mutual authentication is a crucial security step that can defend against many adversarial attacks, [3] which otherwise can have large consequences if IoT systems (such as e-Healthcare servers) are hacked. In scheme analyses done of past works, a lack of mutual authentication had been considered a weakness in data transmission schemes.
All social engineering techniques are based on exploitable weaknesses in human decision-making known as cognitive biases. [5] [6]One example of social engineering is an individual who walks into a building and posts an official-looking announcement to the company bulletin that says the number for the help desk has changed.
In the context of information security, and especially network security, a spoofing attack is a situation in which a person or program successfully identifies as another by falsifying data, to gain an illegitimate advantage.
Business impersonation scams are often easy to spot -- if you know what to look for. If you get an email from a legitimate business, look at the sender email address carefully. Scammers might use ...
In cryptography and computer security, a man-in-the-middle [a] (MITM) attack, or on-path attack, is a cyberattack where the attacker secretly relays and possibly alters the communications between two parties who believe that they are directly communicating with each other, where in actuality the attacker has inserted themselves between the two user parties.
Of police impersonation episodes, 45% occurred on a highway, roadway, or alley; 20% occurred in or near the victim's home (such as a fake "knock and talk"); and 34% occurred in some other place. [1] The study found that only 46% of police impersonation incidents were "cleared" (i.e., arrest made or resolved in some other way). [1]
IP address spoofing is most frequently used in denial-of-service attacks, [2] where the objective is to flood the target with an overwhelming volume of traffic, and the attacker does not care about receiving responses to the attack packets. Packets with spoofed IP addresses are more difficult to filter since each spoofed packet appears to come ...
This attack can be performed either at close range (by directly looking over the victim's shoulder) or from a longer range with, for example, a pair of binoculars or similar hardware. [2] Attackers do not need any technical skills in order to perform this method, and keen observation of victims' surroundings and the typing pattern is sufficient.
