Encryption and security protocols generally prevent an attacker from tapping into the air and reading data as it passes by. Moreover, the network security protocol is essential because it helps to protect the data in the user’s network. Windows Vista initiatives for wireless networking and supports the major security protocols. This ensures that there is interoperability between the wireless network infrastructure and Windows Vista. Moreover, this is regardless of the manufacturer. 

Which Of The Following Are Available Protocols For Security Purposes? (Choose All That Apply.)

Therefore, the user may wonder, “which of the following are available protocols for security purposes? (choose all that apply.)” There are several options there. The possibilities are TLS, NetBIOS, SSL, IPSec, SSH.

Among the five options, TLS, SSL, IPSec, and SSH are available protocols for security purposes.


Users sent data between themselves over the Internet. They may send some private and sensitive information. Password, credit or debit card numbers, or some personal correspondence are some of the examples. TLS ensures that eavesdroppers and hackers are unable to see what the users are transmitting

Transport Layer Security or, in other words, TLS encrypts data sent over the Internet. TLS is a cryptographic protocol that provides end-to-end security of these transmitted data. It is familiar to users through its use in secure web browsing. During a secure session, the padlock icon will appear in the browser.


Secure Sockets Layer or SSL is the most widely deployed cryptographic protocol. It provided security over Internet communications before being succeeded by TLS in 1999. It provides a secure channel between two machines or devices operating over the Internet. Even it is applicable when two machines are operating over an internal network. One typical example is when SSL is used to secure communication between a web server and a web browser. As a result, the website’s address changed into HTTPS from HTTP. The “s” stands for ‘Secure’.


A standard IPSec working group of the Internet Engineering Task Force defines it. IPSec provides integrity, authentication, and data privacy between any two IP entities, and It is an Internet standard for encrypted IP traffic. It uses an IETF-defined key management protocol called Internet Key Exchange (IKE). IKE is used for manual or dynamic management of cryptographic keys and security associations. Therefore, users can create virtual private networks or VPN with this IPSec. VPN through a secure tunnel called security association enables an enterprise to extend its private network such as the Internet. Therefore, the IPSec VPNs protect sensitive data within the enterprise’s internal network. It also enables the secure transfer of data over the public Internet for the same business and business-to-business communications. IPSec provides end-to-end encryption. It encrypts data before tunneling across it. 

There are two versions of the IKE protocol. The IKE version 1.0 or IKEv1 is supported by z/OS®. The IKE version 2.0 or IKEv2 is supported by z/OS V1R12. Users can use IPSec over an established PPTP link. 


The SSH, or in other words, Secure Shell or Secure Socket Shell, is another renowned network protocol. It provides a password or public key-based authentication. Moreover, it gives encrypts the connection between two network endpoints. It is a secure alternative to legacy login protocols such as telnet and rlogin.
