In what file would you make changes to SSH to for more security?

All the configuration setting of SSH server can be done by modifying ssh_config file.

Is SSH hackable?

SSH is one of the most common protocols in use in modern IT infrastructures, and because of this, it can be a valuable attack vector for hackers. One of the most reliable ways to gain SSH access to servers is by brute-forcing credentials.

Is SSH more secure than TLS?

If you really looking for SSH vs SSL(TLS) then the answer is SSH. For one reason why SSH wins over SSL is the way it performs Authentication. Because of this reason when using FTP use SSH protocol (SFTP) rather then FTPS (FTP over SSL).

Is port 22 safe to open?

Yes it is bad practice because every hacker knows the ssh port is 22 and they will easily enter to your server by using their scripts so for prevention just use the modified ports for ssh and firstly open the ssh port on firewall and then in ssh configuration file and then check that it is changed or not.

Is RSA SSH safe?

It’s using elliptic curve cryptography that offers a better security with faster performance compared to DSA or ECDSA. Today, the RSA is the most widely used public-key algorithm for SSH key. But compared to Ed25519, it’s slower and even considered not safe if it’s generated with the key smaller than 2048-bit length.

Can SSH be sniffed?

It is well known that SSH is a secure network protocol, inherently safe from network packet sniffing and eavesdropping. This is of course thanks to its use of encryption.

What is SSH exploit?

SSH Key Persistence- Post Exploitation This can be achieved with the help of the Metasploit module named “SSH Key Persistence-a post exploit” when port 22 is running on the host machine. This module will add an SSH key to a specified user (or all), to allow remote login on the victim via SSH at any time.
