(26 cards)
What does IPSEC stand for?
Internet Protocol Security
True or False: IPSEC can provide both encryption and authentication.
True
What is one major advantage of using IPSEC?
It provides secure communication over an unsecured network.
Fill in the blank: IPSEC is commonly used to create ________ networks.
Virtual Private
Which protocol does IPSEC primarily operate at?
Network layer
What is a disadvantage of IPSEC?
It can introduce latency due to encryption overhead.
True or False: IPSEC can only be used in IPv4 networks.
False
What is the function of the Authentication Header (AH) in IPSEC?
To provide authentication and integrity for IP packets.
What does the Encapsulating Security Payload (ESP) provide?
Encryption, authentication, and integrity.
Multiple choice: Which of the following is a disadvantage of IPSEC? A) High security B) Complexity C) Low latency
B) Complexity
What is the impact of IPSEC on network performance?
It may decrease performance due to processing overhead.
True or False: IPSEC can be implemented in both transport and tunnel modes.
True
What does tunnel mode in IPSEC do?
It encapsulates the entire original IP packet.
What is a key advantage of using IPSEC for remote access?
It allows secure connections for users in different locations.
Fill in the blank: IPSEC can be configured to use various ________ algorithms.
encryption
Which IPSEC mode is typically used for site-to-site connections?
Tunnel mode
Multiple choice: What is a common use case for IPSEC? A) Streaming video B) Secure VPN connections C) Online gaming
B) Secure VPN connections
What is the role of the Security Association (SA) in IPSEC?
It defines the parameters for the secure communication channel.
True or False: IPSEC requires additional configuration compared to other security protocols.
True
What is the effect of NAT on IPSEC?
It can break IPSEC connections unless specific configurations are made.
What is one advantage of IPSEC over SSL/TLS?
It operates at the network layer, securing all traffic, not just web traffic.
Fill in the blank: IPSEC can be used to protect ________ traffic.
any IP
Which two protocols are commonly used in IPSEC?
AH (Authentication Header) and ESP (Encapsulating Security Payload)
What is a disadvantage of IPSEC regarding interoperability?
Different implementations may not work seamlessly together.
