How SSH Works?

If you’re Linux or Mac user, then using SSH is simple. If you use Windows, you will need to utilize an SSH client to open SSH connections. The most popular SSH client is PuTTY, which you can learn more about here.

For Mac and Linux users, head over to your terminal program and then follow the procedure below:

The SSH command consists of 3 distinct parts:

ssh {user}@{host}

The SSH key command instructs your system that you want to open an encrypted Secure Shell Connection. {user} represents the account you want to access. For example, you may want to access the root user, which is basically synonymous for system administrator with complete rights to modify anything on the system. {host} refers to the computer you want to access. This can be an IP Address (e.g.
244.235.23.19) or a domain name (e.g. www.xyzdomain.com).

When you hit enter, you will be prompted to enter the password for the requested account. When you type it in, nothing will appear on the screen, but your password is, in fact being transmitted. Once you’re done typing, hit enter once again. If your password is correct, you will be greeted with a remote terminal window.

What is Cookie theft?

Cookie theft also known as sidejacking or session
hacking, happens when cookies from the websites you
visit are stolen through an unsecure connection. The
cookie can then be used to allow the hacker to pretend
they are you. They can’t necessarily gain access to your
login credentials, but they can access the site as you
(using your session ID) and change your account settings
to hijack it.

How to avoid this technique:

• Make sure you’re always visiting a secure site https not http.
• Use a host VPN to encrypt your traffic.

What is FTP?

File Transfer Protocol (FTP) is, as the name suggests, a protocol used to allow remote transfer of files over a network. It uses a client-server model to do this, and- as we’ll come on to later- relays commands and data in a very efficient way.


How its work?

FTP session operates using two channels:

• Command/Control channel
• Data channel

The command channel is used for transmitting commands as well as replies to those commands, while the data channel is used for transferring data.

What is Cryptography?

Cryptography is associated with the process of converting ordinary plain text into unintelligible text and vice-versa. It is a method of storing and transmitting data in a particular form so that only those for whom it is intended can read and process it. Cryptography not only protects data from theft or alteration, but can also be used for user authentication.

Why we need cryptography?

Without encryption communications over the internet will be very insecure, and it would be very easy for someone to see your data. Fortunately this isn't true, and almost all of the data you get/send over the internet is encrypted and cannot be seen in plain text by someone who got access to it.

Types of Cryptographic Techniques?

Cryptography is used in many applications like banking transactions cards, computer passwords, and e- commerce transactions.

There are
Three types of cryptographic techniques used in general-:

1. Symmetric-key cryptography

2. Hash functions.

3. Public-key cryptography


Symmetric-key Cryptography: Both the sender and receiver share a single key. The sender uses this key to encrypt plaintext and send the cipher text to the receiver. On the other side the receiver applies the same key to decrypt the message and recover the plain text.

Public-Key Cryptography: This is the most revolutionary concept in the last 300-400 years. In Public-Key Cryptography two related keys (public and private key) are used. Public key may be freely distributed, while its paired private key, remains a secret. The public key is used for encryption and for decryption private key is used.

Hash Functions: No key is used in this algorithm. A fixed-length hash value is computed as per the plain text that makes it impossible for the contents of the plain text to be recovered. Hash functions are also used by many operating systems to encrypt passwords.
