Why is port 22 attacked?
As the Dshield graph for port 22 shows, it is a popular target for attackers. These attacks usually take the form of attempts to brute force root accounts and other accounts with weak passwords. My primary method of protecting SSH servers is threefold: Deploy the SSH server on a port other than 22/TCP.

Is port 8080 vulnerable?
The web api server on Port 8080 of ASUS HG100 firmware up to 1.05. 12, which is vulnerable to Slowloris HTTP Denial of Service: an attacker can cause a Denial of Service (DoS) by sending headers very slowly to keep HTTP or HTTPS connections and associated resources alive for a long period of time.
Is it safe to open SSH port?
IMO SSH is one of the safest things to have listen on the open internet. If you’re really concerned have it listen on a non-standard high end port. I’d still have a (device level) firewall between your box and the actual Internet and just use port forwarding for SSH but that’s a precaution against other services.
Is SSH safe?
SSH provides password or public-key based authentication and encrypts connections between two network endpoints. It is a secure alternative to legacy login protocols (such as telnet, rlogin) and insecure file transfer methods (such as FTP).
What are SSH attacks?
An SSH Brute Force attack is a form of cybersecurity attack in which an attacker uses trial and error to guess credentials to access a server. Unlike a lot of other tactics used by cybercriminals, brute force attacks aren’t reliant on existing vulnerabilities.
Why does SSH listen on Port 22?
By default, ssh listen on port 22 which means if the attacker identifies port 22 is open then he can try attacks on port 22 in order to connect with the host machine. Therefore, a system admin chooses Port redirection or Port mapping by changing its default port to others in order to receive the connection request from the authorized network.
