Richter from Pixabay By default Digital Ocean Droplet will allow root SSH access When we first create a droplet in DO, DO will send us the credential access through our email and we can access the droplet using DO console easily. After that we will change the password to our own password. Then whats next? Are we good to go? Before we go in depth. Let us revisit what is a brute force attack. A brute force attack is an attempt to crack a password or username or find a hidden web page, or find the key used to encrypt a message, using a trial and error approach and hoping, eventually, to guess correctly. - Kapersky In case of droplet users, we need to secure our VPS from being attacked by brute force attack. On SSH brute force attack the mechanism is slightly different. The mechanism is SSH brute-force attack, the mechanism is reversed. Instead of trying thousands of username and password combinations on a single server, the crooks try one username and pas...
