PuTTY can be handy for connecting to Linux based EC2 instances in Linux. Therefore, in this article, we will be discussing PuTTY and the purpose of PuTTY. Furthermore, I will also provide you guidelines for downloading PuTTY for using it to connect Linux based EC2 instances.
What is SSH?
Before we start talking about PuTTY, let’s obtain some knowledge about SSH.
Secured Shell popularly known as SSH, is a cryptographic network protocol that is used for secure remote login from one computer to another. This protocol provides various alternative options for strong authentication. Also, with strong encryption, it preserves data confidentiality and integrity. Furthermore, it can be an alternative for unprotected login protocols (such as telnet, rlogin) and insecure methods of file transfer (such as FTP).
Besides, SSH also protects the network against attacks such as IP spoofing, routing source IP and spoofing DNS. Here, an intruder which has succeeded in taking over a network can only compel SSH to disconnect. However, once encryption is allowed, the person cannot playback the traffic or hijack the link.
Now, since we have talked much about SSH, we can dive into the concept of PuTTY. PuTTY is an SSH and Telnet client, which was developed for Windows platform by Simon Tatham. A PuTTY is open-source software that is available with source code and is developed and supported by a volunteer group.
