- What is the fundamental principle that uses multiple layers of security controls instead of relying on a single defense?
Show answer
Defense in depth- What type of firewall maintains information about the state of network connections and makes decisions based on connection context?
Show answer
Stateful firewall- What encryption method uses the same key for both encryption and decryption?
Show answer
Symmetric encryption- What encryption method uses a public key to encrypt and a private key to decrypt?
Show answer
Asymmetric encryption- What cryptographic function produces a fixed-length output from any input and is designed to be one-way?
Show answer
Hash function- What network device monitors traffic and alerts or blocks suspicious activity based on known patterns and rules?
Show answer
Intrusion detection system (IDS)- What is the name of the security model centered on three core principles: Confidentiality, Integrity, and Availability?
Show answer
CIA triad- What security principle restricts users to the minimum access they require to perform their job?
Show answer
Least privilege- What is a control that requires different people to authorize or perform critical tasks to prevent fraud?
Show answer
Separation of duties- What cryptographic technique uses a random value added to passwords before hashing?
Show answer
Salt- What is a precomputed table of hash values for commonly used passwords?
Show answer
Rainbow table- What security measure divides a network into separate segments to limit lateral movement?
Show answer
Network segmentation- What is a demilitarized zone (DMZ) in network security?
Show answer
A separate network segment that sits between internal networks and the internet to isolate public-facing services- What technology creates an encrypted tunnel between two networks or devices over an insecure network?
Show answer
Virtual Private Network (VPN)- What does a proxy server do in a network?
Show answer
Acts as an intermediary between clients and servers, forwarding requests and responses
