Linux Server Support, Security & Hosting Administration
Complete Linux web-server support: troubleshooting, multi-site recovery, security hardening, malware scanning, updates, hosting panels and migrations.
Tell us the Linux distribution, hosting panel if any, approximate number of websites and the symptoms you are seeing.
Complete Linux server support — from one website to the whole hosting environment
A server problem can affect every website hosted on it. MIDOSSA can investigate the complete Linux hosting environment, not only an individual WordPress, Joomla or PrestaShop installation. This is especially useful after a compromise, repeated reinfections, unexplained downtime or when several websites on the same server show suspicious behavior.
Multi-Site Incident Recovery
Analyze multiple websites hosted on the same server, identify suspicious files and common infection patterns, isolate affected sites where appropriate and coordinate cleanup across WordPress, Joomla, PrestaShop and PHP applications.
Server Security Hardening
Review exposed services, SSH access, users, permissions, firewall rules, PHP configuration, web-server settings, backups and other practical attack-surface controls.
Hosting Platform Administration
Installation, configuration, troubleshooting and migration assistance for common hosting control panels including Plesk, HestiaCP and cPanel/WHM where licensing and platform requirements permit.
Linux server security & malware investigation
- Full hosting-environment review after website compromises
- Cross-site malware and reinfection investigation
- ClamAV installation, configuration and malware scanning
- Firewall setup and review using appropriate Linux firewall tooling
- Fail2ban and brute-force protection where appropriate
- SSH access and authentication review
- User, group, ownership and file-permission review
- Suspicious cron jobs, startup tasks and persistence indicators
- Web-shell and suspicious PHP-file investigation
- Log review to support incident diagnosis
Server administration & maintenance
Operating System Updates
Linux package updates, security patches, repository checks and controlled maintenance with attention to service compatibility and recovery planning.
Web Stack
Apache, Nginx, PHP/PHP-FPM, MySQL/MariaDB, SSL/TLS, DNS, cron, permissions and common website-hosting dependencies.
Performance & Capacity
Investigate high CPU, memory pressure, full disks, database load, PHP workers, web-server bottlenecks and resource issues affecting hosted websites.
Backup & Recovery
Review server and website backup strategy, retention, off-server copies and practical recovery readiness before major changes.
Server Migration
Move multiple websites, databases, SSL certificates, PHP configurations, scheduled tasks and hosting workloads to a new Linux server.
Control Panels
Plesk, HestiaCP and cPanel/WHM installation or troubleshooting, plus website-account migration and hosting-environment organization.
Typical situations we can investigate
- Several WordPress sites infected on the same VPS
- Websites become reinfected after individual cleanup
- Server disk suddenly fills up
- High CPU or RAM usage causes websites to become slow or unavailable
- PHP-FPM, Apache, Nginx, MySQL or MariaDB service problems
- SSL or DNS configuration issues
- Hosting panel installation or migration
- Old Linux server requiring updates and security review
- Moving dozens of websites to a cleaner hosting environment
- Preparing a new VPS for secure website hosting
A server compromise needs a wider investigation
Cleaning one infected website may not solve the incident if another account, shared directory, compromised credential or server-level weakness is allowing the attacker to return. For multi-site incidents, MIDOSSA can widen the investigation to the hosting environment and help prioritize containment, cleanup, patching and hardening.
Important: security tools such as ClamAV, firewalls and Fail2ban are useful layers, but no single product makes a server impossible to compromise. We combine tooling with configuration review, updates, access control and practical investigation.
