Opting for a Linux VPS can often be the right decision. Virtual Private Servers, more commonly referred to as VPSs, are a type of hosting service that enables multiple clients to share resources on one physical server – similar to shared hosting, but with one key difference: there’s no resource allocation, so things may become messy quickly and tenants lose performance as a result – something which doesn’t bode well when considering things such as performance, security, SEO or other considerations.
1) Find A Reputable Hosting Company
Your choice of hosting provider could have an immense impact on the degree of security offered by Linux VPSs. Before purchasing one, carefully evaluate its security measures, support options and data center dependability before settling on one provider – we may suggest HostZealot’s debian-based VPS hosting service as they offer various VPS options in safe datacenters all over the world with round-the-clock service and safe hardware, SSD and NVMe storage for instance.
2) Use Logs To Keep Track Of What’s Going On.
Logs provide vital data regarding server activity such as login attempts, successful and failed uploads, errors and problems, which system administrators can use to ascertain whether an action taken by someone responsible or someone unfamiliar is indeed occurring. By monitoring server logs you may help detect an attempted cyber assault so don’t ignore them!
3)Unused Ports Should Be Turned Off.
Linux installations often leave open certain ports, even if they’re not needed. Each open port could potentially be exploited to gain entry to your VPS; so it is wise not to leave them open unless necessary.
4)Use Gnupg Encryption.
To protect the confidentiality of your data while it travels over the Internet, all available encryption methods should be utilized. Although HTTPS protects some information between client and website, some remains susceptible to eavesdropping; to store such sensitive information safely use the asynchronous encryption offered by GnuPG app.
5) Make Use Of Strong Passwords.
Simply put: it’s that straightforward. No matter how secure everything else may be, having an insecure password could still pose an immense security threat. Therefore, take special care in choosing one containing at least 10-12 characters that contain numerals, special characters and upper and lowercase letters – this should provide ample security protection.
6) Make Use Of Partitioning.
If an attacker gains access to your system, you can still increase its safety by partitioning disk space so they cannot immediately gain access to certain areas.
7) Ftp Encryption
As its name implies, FTP is used for transporting data. On the other hand, SFTP encrypts both data and credentials before flying them out securely.
8) Maintain An Eye Out For Fixes And Updates.
Development communities are constantly working on fixing faults and vulnerabilities within systems, so to maintain its safety as much as possible it is only natural that all updates or patches be applied as soon as they become available.
9) Disable Anonymous Ftp Uploads.
Anonymous FTP uploads are another default feature that could put your Linux VPS at risk, as strangers could gain entry and infiltrate it with malware without your knowledge. To disable it, navigate to /etc/vsftpd/vsftpd.conf and set anonymous enabled=NO in the relevant settings.
10) Modify The Default Ssh Port Setting.
SSH stands for Secure Shell and allows remote access to servers securely. Unfortunately, its default number of 22 makes this vulnerable port an opportunity for hackers to gain entry without authorization into your server.
