VPS hosting is a highly efficient way to store and manage private and sensitive data. However, it is not exempted from security threats. Here is a list of five things you need to take care of to ensure the information in your VPS server is secure.
1. Do a Thorough Audit of the Server
The first and the most important thing you need to do is to conduct a thorough audit of the server. This way, you will know the potential risks your system faces and understand which areas are more likely to be affected. There are several tools you can use to conduct an audit. For a one-time audit, you can use Baseline, Profiler, DSAuditors and SQL Watch. For repeated audits, you can establish a customizable and automated auditing system with Logwatch.
In addition to determining the potential risks your system faces, you need to take a closer look at the applications and services running on your VPS server. Identify which applications are necessary for the VPS to function and which ones need restructuring.
Note, all audits should apply to all systems, including dedicated servers.
2. Update Regularly
Update your VPS server regularly, ensuring that it has the latest security software. This is important because updates contain new security patches whose vulnerabilities plague those found in the older ones. Also, make sure you have backups of every information on your VPS to prevent huge losses during updates.
3. Limit Server Access
You need to limit server access to only those people who need it. You can use an advanced policy firewall (APF) to allow easy management of your firewall rules or ConfigServer firewall (CFS) that also control firewall rules but has more advanced features. Alternatively, you can close some open ports in the server firewall. Only allow open ports that are needed for external communication. You can also activate the cPHulk protection to automatically block individuals who try to gain access with incorrect details.
4. Use Strong Passwords
The first security mechanism for all services that run on your server should be a strong password. Make sure you are using a password that is difficult to crack. It can be a combination of numbers, letters or special characters. You can also use abbreviations of sentences you can easily recall.
5. Be Vigilant Against Common Security Threats
You need to maintain constant vigilance of your system. Remain constantly aware of the possible security threats your system may be predisposed to at any given moment and come up with effective preventive mechanisms to deal with such threats if they occur. Run regular virus scans and check your security logs more often. Disable all compilers and use Apache 2.2 or higher for the system. Also, configure your system to display any warning messages whenever there is unauthorized access. You may find it useful to visit Cirrus Tech for more information.
