Security is important for anyone who wants to keep their online business intact. The risk of security challenges, starting with the theft of sensitive files and the destruction of your important data, increases. Experts estimate that the damage from cybercrime will reach $ 6 trillion next year.
Under such circumstances, it is natural that everyone would like to implement all possible strategies to stay safe. Here are some tips on how to protect your Server:
Keep backups
There are two classes of people: those who back up from scratch and those who do it the wrong way. Don't be one of the second category. So set up automatic backup so you can recover the important ones data in an emergency need. Be sure to save them remotely, otherwise if something goes wrong with your current server, your data may be lost. Using remote file server solutions, such as Triofox, will cover you.
Protect SSH
This is more relevant for those using a Linux server, as using SSH is more common on Unix-based systems. First, change port 22 to a custom one, as most attacks target the default ports (speaking of ports, it is also worth turning off all unused ports, as they can be used to expose your network). Make sure you replace the login with a password for SSH keys using a passphrase, as it is harder to guess and therefore more secure. Then create a custom user with sudo privileges and disable root. Root has the highest access, and if it is compromised, your server is completely exposed.
Use SSL
SSL helps create an encrypted channel for respchange information, between the client's browser and a server, to prevent hacking and theft of passwords, credit card details and other sensitive information being transmitted. So installing an SSL on your website ensures a secure connection.
Set up Server monitoring
Monitoring your server logs, which are generated by essential services and software installed on the server, ensures that you will be in control of everything that is happening. This way you can spot any worrying logs, abnormal activity and movement users and resolve issues before they become critical.
Protection against malicious attacks
Σε προσπάθειες προστασίας του διακομιστή σας από κακόβουλες επιθέσεις , αξίζει να προστατευτείτε με τείχος προστασίας για να φιλτράρετε την εισερχόμενη κίνηση και να αποκλείσετε τυχόν ύποπτα αιτήματα. Το επόμενο βήμα είναι η παρακολούθηση των αρχείων που μεταφορτώνονται στον διακομιστή με ένα αξιόπιστο λογισμικό προστασίας από ιούς που θα θέσει εγκαίρως σε καραντίνα τα ανεπιθύμητα αρχεία. Μια άλλη απειλή έρχεται με επιθέσεις όπου οι εισβολείς για να μπουν χρησιμοποιούν διάφορους συνδυασμούς κωδικών πρόσβασης. Δυστυχώς, αυτές οι επιθέσεις είναι συχνά επιτυχείς, οπότε η χρήση λύσεων όπως το CSF (για Linux) ή το BFGuard (για Windows) can help you combat these attacks by blocking IP addresses after a certain threshold of failed connection attempts.
Another popular attack is DDoS which aims to overload a request server in order to drop it. Unfortunately, there is no 100% way to protect against them, as traffic is generated by multiple networks at once, but reducing the rate of incoming requests and using protection solutions (such as Imperva or CloudFlare) can help you mitigate them faster.
Applying these tips will help you ensure a better level of protection for your server, however, it is not a panacea and a one-time solution. Maintaining a server requires constant attention, timely software updates, and regular security checks.
Certainly, some technical skills are required to apply these tips and you may need to hire a system administrator to get everything right. But these investments are justified, as they give you the peace of mind to manage your server smoothly.
