A cloud server can be launched extremely swiftly. It simply takes a few clicks to do so. You have a Go4hosting dashboard along with a control panel that can be used to launch a server within 30seconds flat. However, once the new server becomes live, you should follow some basic steps for keeping it protected from any sort of vandalism. Servers that are available to all and sundry on the World Wide Web stands exposed to all kinds of threats. Here are some helpful suggestions that can provide complete protection to cheap Cloud Hosting users.
Some Simple Ways to Protect your Password
1. Give Password Logins a Miss:
Using passwords to log into your account is one of the gross mistakes you can actually commit. Passwords, no matter how cleverly created and innovatively imagined, can be fairly easily cracked either by keyloggers or by brute force. The more secure way to log in is through SSH keys. It not only guarantees more security but is more convenient for your access as well. Often times, innovative passwords are difficult to remember and goof-ups are possible. Luckily, if it is already SSH configured and allows a key login and disallows passwords. So make sure you stick to SSH keys alone.
2. Enabling Upgrades is always a Good Idea:
In order to keep your server safe from all sorts of attacks, the line of defence needs to be kept strong. The best line of defence for any server is to keep its line of defence extremely strong. And this will require ensuring that all packages included in the server hosting plan are updated. Vulnerabilities increase when packages are not updated. You need to allow automatic unattended upgrades for keeping your server safe and secure. In some cases, upgrades are allowed only post permission. When the permissions are not provided, the updates remain pending and during that period, the server remains vulnerable to external attacks. This is why unattended upgrades are the best solutions.
3. Rely on Fail2Ban:
Additional tools may also need to be engaged in securing your server. Tools like Fail2ban can help by scanning log files. It also bans suspicious IP addresses, attempts at password hacking determined by too many failed attempts, seeking for exploits and so on. Generally, it is used for updating Firewall norms and rejecting IP addresses for a specified period of time. However, other arbitrary actions can also be taken by suitably configuring Fail2ban. For instance, you can use it for sending messages through emails. Fail2ban also comes with specific filters meant for different services including SSH, Apache, and Courier. However, these may not be included in default enabling, they need to be added as additional, later. It is wise to check the documentation of Fail2ban to understand what all it can actually offer.
4. Keep an Eye Always:
The best way to protect your server is to stay informed. You need to have a system in place where you can be notified when things start getting abnormal and weird. And the best way to do it is by engaging Log-watch. With the help of Log Watch, we can keep looking at the system logs for keeping an eye. Log watch is the easiest package for installations and is a fairly common tool for securing servers. However, it is always prudent to check the specifications before engaging.
5. Security Groups can Work Wonders:
Security groups can often be used for filtering the internet traffic. It scans the traffic and allows entities that are indispensable. Forming such groups is considered one of the most effective ways to filter traffic. By default, a cloud server hosting allows traffic to HTTP port 80 and SSH port 22. You will need to refer to additional guidelines for opening other ports.
Intrusion Detection Systems work Wonders:
One more smart way of managing and controlling threats is to engage an intrusion detection system like Tripwire. You need to read through the instructions of the system before engaging it.
It is important to note that all these steps need to be executed for ensuring complete safety of freshly created servers. This is, however, a simple and basic guide. There are other applications and services running on these servers. Common servers include Apache web server, applications like Java, Python, and PHP and so on. For these applications, extra steps for additional security will have to be undertaken. Before launching one such server on the web, it is important to read through one such comprehensive guide that helps in securing servers.
