After using nmap to scan the server, it was found that insecure algorithms are used. This may allow attackers to compromise the secure communication.
Are there ways to remediate this issue? Have tried to disable ciphers and key exchange algorithm on Windows, but does not work.
These are the affected algorithm:
- diffie-hellman-group14-sha1
- ssh-dss
- ssh-rsa
- hmac-sha1hmac-sha1-etm@openssh.com
Steps to reproduce:
1) Download Nmap (https://nmap.org/download)
2) Run Nmap scan using the following command:
Nmap -Pn -sV -script ssh2-enum-algos -p22 <Server IP Address>
