Server protection is a hot topic these days. With an ever-increasing menu of methods employed by hackers to breach sensitive data, it is more important than ever to shield your server from would-be attackers. Luckily, there are two simple preventative measures which can help you keep your information safe and secure.
How Do I Protect My Server? SSH Keys
How do I protect my server? Prevention is key. With cybersecurity, as in life, it is always better to err on the side of safety. One of the simplest approaches is to set up SSH keys which use more bits of data than a regular password. SSH keys force attackers to attempt significantly more combinations, rendering computer algorithms essentially useless for cracking the key. SSH keys are simple to configure and can be up and running in a matter of minutes.
Firewalls Are Your Friend
If SSH keys are like a password, then firewalls are like a filter. Firewalls will only allow in network traffic based on your customised security rules. This means that you can restrict access to all but the exact services required. Firewalls are relatively easy to set up, and the settings can be altered at any point in the future if your needs change.
Keep Your Server Safe
There are a variety of methods to protect your server from attacks, but two of the simplest to apply are SSH keys and firewalls. SSH keys impede the attacker’s ability to crack passwords, while firewalls stop unwanted network traffic from getting in or out. Both barriers are relatively simple to set up and can be updated easily as your security needs change.
