IP Security - Internet Key Exchange (IKE)

What is IKE in the context of IP Security?

• Internet Key Exchange

• Internet Key Encryption

• Internet Key Exchange Protocol

• Internet Key Establishment

What is the purpose of IKE?

• To play video games

• To establish a connection with social media platforms

• To establish a secure and authenticated communication channel by negotiating security associations.

• To order food delivery online

Explain the main phases of IKE.

• Phase 2 and Phase 3

• Phase 1, Phase 2, and Phase 3

• Phase 1 and Phase 3

• Phase 1 and Phase 2

What are the key components of IKE?

• Main Mode

• Slow Mode

• Main Mode, Aggressive Mode, Quick Mode, Informational Mode

• Passive Mode

How does IKE ensure secure communication?

• By sharing authentication credentials openly

• By sending data over unsecured channels

• By using weak encryption methods

• By establishing a secure, authenticated, and encrypted connection between two parties before any data is transmitted.

What is the role of the Security Association (SA) in IKE?

• Managing user authentication for network access

• Ensuring data integrity during transmission

• Negotiating and establishing security parameters between communicating entities

• Providing physical security to network devices

What are the differences between IKEv1 and IKEv2?

• IKEv1 and IKEv2 have the same level of security, efficiency, and flexibility.

• IKEv2 is more secure, efficient, and flexible than IKEv1.

• IKEv2 is less secure, efficient, and flexible than IKEv1.

• IKEv1 is the latest version and IKEv2 is outdated.

How does IKE handle key management?

• IKE uses symmetric key encryption for key management

• IKE relies on public key infrastructure (PKI) for key management

• IKE generates new keys for each session without negotiation

• IKE negotiates and establishes security associations (SAs) between parties using encryption algorithms.

Discuss the importance of Perfect Forward Secrecy (PFS) in IKE.

• PFS in IKE is only useful for short-term security

• PFS in IKE does not impact the security of the communication

• PFS in IKE is primarily focused on speed rather than security

• PFS in IKE is crucial for maintaining confidentiality and security by preventing the compromise of past session keys even if the long-term secret key is exposed.

What are the potential security threats to IKE and how can they be mitigated?

• Use weak encryption algorithms, implement insecure key exchange protocols, and disable authentication mechanisms.

• Ignore encryption altogether, use unsecured key exchange protocols, and allow anonymous access.

• Implement outdated encryption algorithms, use compromised key exchange protocols, and share authentication credentials openly.

• Use strong encryption algorithms, implement secure key exchange protocols, and enable authentication mechanisms.
