How is phishing done?
Phishing is a form of social engineering attack that is frequently employed to steal user information, such as login credentials and credit card numbers. It happens when an attacker deceives a victim into opening an email, instant message, or text message by disguising themselves as a reliable source.
Why is the term phishing used?
The term “fishing” is a leetspeak variant that alludes to the use of increasingly sophisticated lures to “fish” for users’ sensitive information. It is likely influenced by the term “phreaking.”
What is firewall Mcq?
Network-based security measures called firewalls regulate the volume of incoming and outgoing traffic.
How is encryption done?
Data is encrypted using sophisticated mathematical algorithms and digital keys. Data is converted into ciphertext using an encryption algorithm (cipher) and encryption key. The same or a different key (cipher) is used to decode the ciphertext back into the original value after it has been transmitted to the recipient.
What are active and passive attacks?
Definition: In active attacks, the attacker tries to tamper with the message’s content by intercepting the connection. In passive attacks, the attacker watches the messages, copies them, saves them, and then can use them for bad intentions. Modification. An active attack involves the attacker changing the actual data.
What is active and passive measures?
Active and passive mitigation are the two main categories. Active mitigation: A mitigation strategy that needs assistance from people in order to be effective. Measures of mitigation that don’t need any help from people to work properly are known as passive mitigation.
