A service model in which applications are provided through an online user interface and are compatible with a multitude of devices and operating systems.​

​In the context of IPsec, a type of encryption that provides authentication of the IP packet's data payload through public key techniques. In addition, it also encrypts the entire IP packet for added security.

A service model in which hardware services are provided virtually, including network infrastructure devices such as virtual servers.​

A Layer 2 communications protocol that enables a workstation to connect to a server using a serial connection such as dial-up or DSL. It can support multiple Network layer protocols and can encrypt transmissions.​

A service model in which various platforms are provided virtually, enabling developers to build and test applications within virtual, online environments tailored to the specific needs of a project.​

An encryption key generation and management scheme used by 802.11i.​

One of two services in the key management phase of creating a secure IPsec connection. It negotiates the exchange of keys, including authentication of the keys. It uses UDP and usually runs on port 500.​

An authentication protocol that operates over PPP and also encrypts usernames and passwords for transmission​

In the context of IPsec, a type of encryption that provides authentication of the IP packet's data payload through public key techniques.​

In Kerberos terminology, the server that issues keys to clients during initial client authentication.​

The ___________cloud service model provides virtual environments online that can be tailored to the needs of developers.

When PPP is used over an Ethernet network, it is known as ____________

​What protocol below only provides the framework for authenticating clients and servers, but relies on other encryption and authentication schemes to verify the credentials of clients or servers?

​What security encryption protocol requires regular re-establishment of a connection and can be used with any type of TCP/IP transmission?

What security principle provides proof of delivery and proof of the sender's identity?​

What two different types of encryption can be used by IPSec during data transfer?​

What two key lengths are the most popular for the SHA-2 hashing algorithm?​

What two options below are AAA services?​

What two protocols below are Data Link Layer protocols designed to connect WAN endpoints in a direct connection, such as when a client computer connects to a server at an ISP using a dial-up or DSL connection and modem?

When using a site-to-site VPN, what type of device sits at the edge of the LAN and establishes the connection between sites?​

When using public and private keys to connect to an SSH server, where must your public key be placed?​
