Selecting a Linux VPS is often a very wise decision. Virtual private servers, often known as VPSs, are a form of hosting service that works by allowing several clients to use the resources of a single physical server. Sounds similar to shared hosting, but there is a big difference: with shared hosting, there isn’t any resource allocation, so things may become messy and the server tenants lose performance, which isn’t great from the perspective of performance, security, SEO, and other factors.
1) FIND A REPUTABLE HOSTING COMPANY
Your choice of hosting company might have a significant impact on your final degree of security before you ever buy a Linux VPS. As a result, you should carefully compare the security measures, support options, and data center dependability offered by various hosting companies, as well as client testimonials. If you want our opinion on this, we may recommend HostZealot’s debian-based vps hosting service. They provide a wide range of VPS in safe data centers across the world, with round-the-clock service, safe hardware, and SSD and NVMe storage.
2) Use Logs To Keep Track Of What’s Going On.
Logs provide information about server activity such as login attempts, successful and failed uploads, problems, and so on. System administrators can utilize the latter to determine if these operations are being carried out by a responsible individual or by a stranger. Monitoring server logs might therefore assist you in detecting a potential cyber assault, so don’t ignore them!
3)Unused Ports Should Be Turned Off.
Various ports are left open when you install Linux, whether you require them or not. Each open port can be used to hack your VPS, therefore don’t keep them open if you don’t need them.
4)Use Gnupg Encryption.
To prevent unauthorized access to your data while it is being transported over the internet, you should use all available encryption methods. Although HTTPS encrypts data exchanged between the client and the website, some data remains vulnerable to eavesdropping. To store it, utilize the GnuPG application’s asynchronous encryption.
5) Make Use Of Strong Passwords.
It’s as simple as that. Even if everything else is good, a weak password might be a significant security violation. As a result, don’t forget to take care of your password by making it long enough – at least 10 to 12 characters, with a variety of characters such as numerals, special characters, and both upper- and lowercase letters.
6) Make Use Of Partitioning.
If an attacker gains access to your system, you may still make it safer by dividing the disk space to separate the disk area they can instantly access.
Use the following commands to safely mount two partitions:
# mount tmpfs /tmp -o noexec,nosuid,nodev
# mount tmpfs /var/tmp -o noexec,nosuid,nodev tmpfs
7) Ftp Encryption
As it is, FTP is the protocol used to transport data. SFTP, on the other hand, encrypts the data as well as the credentials and flies.
8) Maintain An Eye Out For Fixes And Updates.
The development community is always striving to repair faults and vulnerabilities in the system. So, in order to maintain it as safe as possible, it’s natural to apply all patches and updates as soon as they are available.
9) Disable Anonymous Ftp Uploads.
Anonymous FTP uploads are another default feature that may pose a risk to your Linux VPS. Strangers may infect your VPS with malware while you are unaware. To turn off this functionality, navigate to /etc/vsftpd/vsftpd.conf. Then, set anonymous enabled=NO in the relevant settings.
10) Modify The Default Ssh Port Setting.
SSH is the port required for secure remote access to a server. Because the default number is always 22, hackers can occasionally utilize this functionality to gain unauthorized access to your server.
