The technical work

Linux Server Security

Start with the work your team needs. These topics guide the scope discussion; your proposal confirms compatibility, included tasks and required licences.

Reduce server exposure

  • System hardening

    Review secure settings, permissions, open ports and unused services.

  • SSH access

    Review key authentication, remote login policy and privileged access.

  • Firewall rules

    Review iptables, firewalld or UFW rules against required traffic.

  • Patches and versions

    Assess kernel and package updates, compatibility and change windows.

  • User privileges

    Review sudo rights, accounts and appropriate access boundaries.

Detect and investigate

  • Intrusion protection

    Review appropriate deployment of Fail2ban, OSSEC or related controls.

  • Malware checks

    Use suitable tools such as ClamAV, rkhunter or chkrootkit for agreed checks.

  • Log analysis

    Review security events, suspicious logins and system warnings.

  • Web and mail security

    Review Apache, NGINX and mail service security settings.

  • Findings and remediation

    Document issues, approved changes and remaining security actions.

Review the environment before changing it.

Include the server versions, roles and current priorities in your inquiry. Access, change approvals and recovery responsibilities are agreed during onboarding.

Your service agreement

Know who handles what.

Start with the systems, responsibilities and intended outcome. SDH confirms compatibility, access, change approval and completion checks before the work begins.

Environments covered
SDH assesses compatibility before starting work. The proposal names each server or website covered by the service. If the environment is unsupported, SDH refunds the payment.
Included work
The accepted task list defines maintenance, monitoring, updates and incident work. SDH provides reports covering issues, updates and completed tasks. You review the work and confirm completion. SDH handles customer communication, prepares and approves quotations, coordinates escalation, and provides a handover when management ends. You approve changes to your environment before SDH proceeds.
Exclusions
Application development, redesigns, licences, infrastructure and projects outside the agreed scope are separate unless expressly included.
Agreed management coverage
Your selected package and accepted proposal define the covered systems, tasks, staffing, hours and escalation responsibilities. Additional time or wider coverage requires your approval and is invoiced separately; a checkout approval or spending limit does not increase the purchased scope.
