There are many types of protocols such as routing protocols, mail transfer protocols, remote communication protocols, and many others. One such category is network security protocols. They ensure that data integrity and security are maintained over a network. These protocols use a variety of techniques and methods to protect the network data against any unauthorized attempt to view or extract the data.
Some Network Security Protocols
These are some of the most popular network security protocols you should know to use when necessary.
- IPSec protocol has been classified by the IETF IPSec Work Group. It provides authentication of data, integrity, and privacy between two entities. An IETF-specific key managing protocol called Internet Key Exchange (IKE) allows for manual or dynamic management of cryptographic keys.
- SSL (or Secure Sockets Layer) is a standard security method used to protect an internet connection. It safeguards sensitive data that is being sent or received between two systems. This helps to prevent cybercriminals from reading and modifying personal data, packets, or details within the network.
- Secure Shell is a cryptographic network security protocol that secures data communication over a network. It was created in 1995. It allows remote command-line login and remote execution of certain tasks. SSH incorporates many functions of FTP. SSH-1, SSH-2, and SSH-3 are the most recent versions of FTP.
- HyperText Transport Protocol Secure (HTTPS), is an encrypted protocol that encrypts data communication between two or more systems. Secure Socket Layer, also known as Transport Layer Security (TLS), was used to establish an encrypted link. Because HTTPS data is encrypted, cybercriminals cannot alter or interpret it during the transmission from the browser to the webserver. The strong encryption that is associated with data packets will prevent cybercriminals from reading them even if they capture them.
- Kerberos, another network validation protocol, was designed to provide strong authentication between client and server applications using secret-key cryptography. Kerberos network validation protocol states that all its services and workplaces are part of an insecure network. This makes it more secure, responsible, and reliable.
It is crucial to be familiar with these protocols and their uses as security professionals. You may encounter situations where HTTPS is converted to HTTPS (also known as a downgrading HTTP attack). If your company’s website opens without HTTPS/SSL, it is possible that the link was opened by spam or illegal mail. This could indicate that someone is trying to phish. Someone is trying to compromise the internal network by downgrading the HTTP attack.
