Server Security Hardening & Malware Remediation
Production infrastructure operations & expert administration
Comprehensive Linux and Windows server security. Firewall configuration, SSH hardening, Fail2Ban, ModSecurity WAF, and malware cleanup services.
Engineering Scope & Deliverables
Concrete administration, tuning, and incident resolution capabilities for this environment.
Firewall & Port Hardening
Configuring CSF/LFD, firewalld, or nftables/iptables with custom rate limits, country blocking, and closing all unnecessary exposed listening daemons.
SSH & Access Security
Enforcing ED25519/RSA-4096 SSH keys, disabling password authentication, moving SSH off port 22, and enforcing sudo audit logs.
Brute-Force & Intrusion Prevention
Deploying Fail2Ban jails and cPHulk rules with progressive ban times for SSH, FTP, webmail, and WordPress wp-login endpoints.
Malware Scanning & Incident Remediation
Deep file scanning using Maldet (LMD) and ClamAV, isolating compromised PHP webshells, cleaning injected backdoors, and repairing core files.
Web Application Firewall (WAF)
Configuring ModSecurity with OWASP Core Rule Set (CRS) or COMODO WAF to block SQL injection, cross-site scripting (XSS), and path traversal.
SSL/TLS Hardening & HTTP Headers
Enforcing TLS 1.2 and 1.3, disabling deprecated ciphers, and deploying security headers (HSTS, CSP, X-Frame-Options, X-Content-Type-Options).

Frequently Asked Questions: Server Security Hardening & Malware Remediation
Common questions about scopes, access models, SLAs, and onboarding.
Something else? Ask an engineer.
How do you respond if a server has been hacked or infected with malware?
We isolate network exposure, audit active processes and cron jobs, scan all web directories with Maldet and ClamAV, remove injected webshells, patch software entry points, and change all server and database credentials.
Do you configure ModSecurity WAF without breaking legitimate website forms?
Yes. We deploy ModSecurity in detection mode initially, tune rules to eliminate false positives for CMS operations, and then enforce active blocking.
