The internet Protocol Security (IPsec) protocol that provides confidentiality by encrypting data is the Encapsulating Security Payload (ESP). ESP ensures data confidentiality through encryption while also providing authentication and integrity for the transmitted data. It is commonly used in virtual private networks (VPNs) to secure communication over untrusted networks.
The most commonly used security protocol for encrypting email is Pretty Good Privacy (PGP) and its open standard version, OpenPGP. Another widely used protocol is S/MIME (Secure/Multipurpose Internet Mail Extensions), which integrates with public key infrastructure (PKI) to provide encryption and digital signatures. Both protocols ensure the confidentiality and integrity of email messages by encrypting the content and authenticating the sender.
IPsec (IP security) is a suite of protocols for securing Internet Protocol (IP) communications by authenticating and/or encrypting each IP packet in a data stream. IPsec also includes protocols for cryptographic key establishment.

The AH (Authentication Header) protocol and the ESP (Encapsulating Security Payload) protocol both function within the network layer. They are part of the IPSec (Internet Protocol Security) standard.
There are two versions of internet protocol. The two versions of internet protocol are version 4 and 6. The Encryption techniques incorporated in IPV6 is IPsecurity .
What is the importance of maintaining security and confidentiality?
Security is an essential part of any transaction that takes place over the internet. Online business uses transport layer security protocol and secure socket layer protocol.

A more secure alternative to using SMTP for outgoing email is the Simple Mail Transfer Protocol Secure (SMTPS), which adds a layer of security by encrypting the connection using Transport Layer Security (TLS). Another option is the use of the Email Message Access Protocol (EMAP) in conjunction with SMTP, which can provide additional security features. Additionally, using secure email services that implement end-to-end encryption, such as PGP (Pretty Good Privacy) or S/MIME (Secure/Multipurpose Internet Mail Extensions), can further enhance email security.
Hypertext Transfer Protocol Secure (HTTPS) is a widely used communications protocol for secure communication over a computer network, with especially wide deployment on the Internet. Technically, it is not a protocol in itself; rather, it is the result of simply layering the Hypertext Transfer Protocol (HTTP) on top of the SSL/TLS protocol, thus adding the security capabilities of SSL/TLS to standard HTTP communications. The Secure Socket Layer (SSL) and Transport Layer Security (TLS) is the most widely deployed security protocol used today. It is essentially a protocol that provides a secure channel between two machines operating over the Internet or an internal network. In today's Internet focused world, the SSL protocol is typically used when a web browser needs to securely connect to a web server over the inherently insecure Internet.
VOIP stands for Voice Over Internet Protocol and is a type of phone line that utilizes the internet. VOIP security uses this phone/internet connection to monitor your home's security and alert officials if there is an alarm.
Hypertext Transfer Protocol Secure (HTTPS) is a combination of the Hypertext Transfer Protocol and a network security protocol. HTTP operates at the highest layer of the TCP/IP Internet reference model, the Application layer; but the security protocol operates at lower sublayer, encrypting an HTTP message prior to transmission and decrypting a message upon arrival. HTTPS has also been known as "Hypertext Transfer Protocol over Secure Socket Layer", but now HTTPS may be secured by the Transport Layer Security (TLS) instead of Secure Sockets Layer (SSL) protocol. To invoke HTTPS, one replaces "http://" with "https://" in the URI, or Web address. HTTPS connections are often used for payment transactions on the Web and for sensitive transactions in corporate information systems.
