What are the three basic concepts of information security?
Confidentiality, Integrity, and Availability (CIA)
What is authentication in the context of information security?
It is a process of verifying the identity of a user, device, or system attempting to access a computer or network.
What is authorization in the context of information security?
It is the process of granting access to a user, device, or system after authentication and determining the appropriate level of access required for that user.
What is an encryption in the context of information security?
It is the process of converting plain text into a coded message to secure and protect its contents from unauthorized access.
What is a firewall and how does it work?
It is a network security system that monitors and filters incoming and outgoing network traffic to prevent unauthorized access. It works by examining packets of data and deciding whether to allow or block them based on predefined rules.

What is a Virtual Private Network (VPN)?
It is a secure and private connection between devices over the internet that allows users to access the internet safely away from prying eyes.
What is the difference between symmetric and asymmetric encryption?
Symmetric encryption uses the same key for both encryption and decryption, while asymmetric encryption uses different keys for encryption and decryption.
What is dumpster diving?
It is a physical method of obtaining private and confidential information by searching through a person's garbages or recycle bins.
What is ransomware?
It is a type of malware that blocks access to a system or data until a ransom is paid to the attacker.
