  • CURRENT - Release candidate
  • STABLE - The last tier to receive changes
  • LTS - Long term support release
  • RELEASE - General availability (recommended)
  • EDGE - Application development and testing only

Cultrix uses the RELEASE tier.

  • CURRENT– feature development is complete in this version and the software passes all known tests. This becomes the next production RELEASE. This RELEASE candidate software may experience limited real-world testing.
  • STABLE– this version has received considerable public exposure, testing, and verification.
  • LTS– more conservative system administrators often completely disable software updates in order to maintain control over their deployments and maintain a standardised software and application environment. The LTS tier provides an alternative to disabling updates, allows a specific version to be chosen while allowing servers to still receive important updates and fixes for as long as the software is supported.
  • RELEASE– when the software reaches this stage it is recommended for widespread production usage. It is feature-complete and well tested. It contains all intended features and functionality.
  • EDGE– this version only has rudimentary testing. The features are subject to further modification. This version usually lacks official public documentation. Due to the dynamic nature of EDGE builds, only use EDGE to test for compatibility and functionality in a controlled environment. This tier is not recommended for production servers.

Operating system

We use the CloudLinux Operating System which is the leading platform for multitenancy. It improves server stability, density, and security by isolating each tenant and giving them allocated server resources. This creates an environment that feels more like a virtual server than a shared hosting account. By limiting server resources like memory, CPU and connections, a single tenant cannot jeopardise the stability or performance of the whole server; and by caging each account it stops security breaches by preventing unstable scripts and malware from spreading to other accounts.

Upgrades and updates are automatically checked for and applied daily as made available. These checks also include upgrades and updates for all additional operating system software that uses the Yum RPM package manager.

Security and firewall

We use a Stateful Packet Inspection (SPI) firewall, and login/intrusion detection and security application. This also provides a Login Failure Daemon (LFD) that prevents brute-force attacks by looking for repeated failed login attempts and blocking offending IP addresses.

Additional Security Software

BitNinja

BitNinja provides additional security by combining the most powerful server security software to protect against XSS, DDoS, malware, scans, script injection, enumeration, brute force and other automated attacks – on all major protocols. BitNinja servers learn from each attack and inform each other about malicious IPs resulting in a global defence network that counteracts botnet attacks with a shield of protection for all servers, while also reducing the number of false positives each server encounters.

cPHulk Brute Force

This service provides protection against brute force attacks, a hacking method that uses automated systems to guess passwords to online services such as email and FTP accounts.

OWASP ModSecurity™

We use the OWASP (Open Web Application Security Project) ModSecurity™ CRS (Core Rule Set) to protect our servers, greatly increasing the protection for web applications.

Apache SpamAssassin™ rules updates

Apache SpamAssassin is the number one open-source, anti-spam platform using filters to classify email and block spam (unsolicited bulk email). It uses a robust scoring framework and plug-ins to integrate a wide range of advanced heuristic and statistical analysis tests on email headers and body text including text analysis, Bayesian filtering, DNS blocklists, and collaborative filtering databases. Apache SpamAssassin is a project of the Apache Software Foundation (ASF).
