S11. What are the differences between TLS and IPSec? Flashcards
What is TLS?
Transport Layer Security is a cryptographic protocol operating at the transport layer
What is IPSec?
Internet Protocol Security is a cryptographic protocol operating at the network layer
What are the commonalities and differences between TLS and IPSec?
They are both cryptographic protocols used to secure communication over networks, but they operate at different layers of the protocol stack.
What does TLS do?
TLS provides end-to-end encryption and authentication between two end-points, such as a browser and a server. It is commonly used to secure data over the Internet, such as web browsing, email, and instant messaging.
What does IPSec do?
IPSec provides network-layer security for all traffic between two networks or hosts, by securing communication between network devices, such as routers or firewalls , encrypting and authenticating IP packets as they traverse the network.
It can protect all traffic passing through a network device, regardless of the applications or protocols involved.
IPSec can be used to create virtual private networks (VPNs) to securely connect remote networks or hosts over the Internet.
How can security settings be configured in TLS vs IPSec?
TLS allows applications to negotiate security settings during the initial handshake. IPSec provides a more standardized and comprehensive set of security protocols and algorithms at the network layer. It offers flexibility in terms of encryption and authentication methods, but typically requires configuration at the network device level rather than the application level.
How is TLS used?
TLS is widely adopted for securing communication over the Internet and is supported by most web browsers, servers, and applications. It is the primary protocol used for securing HTTPS connections.
How is IPSec used?
IPSec is commonly used in enterprise networks and VPN deployment to secure communication between remote sites or mobile clients.
