Hardening a Linux server helps prevent malware from gaining an initial foothold and limits what a compromised service can access. Start by keeping software patched, removing unnecessary packages, restricting administrator access and inbound traffic, and confining applications with the mandatory access control system supported by your distribution. The commands and defaults below are Ubuntu-specific; on other distributions, follow the security documentation for the installed release rather than assuming Ubuntu settings apply.
What hardening can—and cannot—do
Hardening reduces avoidable exposure and limits the reach of a process if it is compromised. It is a set of complementary controls, not a guarantee that malware cannot enter or run. Ubuntu’s security guidance describes layered security and notes that its general recommendations are not a complete hardening guide. Ubuntu security introduction
For a practical baseline, address software maintenance, privileges, network exposure, remote administration, and application confinement. Keep the controls compatible with how the server is operated: an inaccessible management port, a broken service profile, or an update workflow that stalls indefinitely can undermine security rather than improve it.
Keep the operating system and applications patched
On Ubuntu Server, unattended-upgrades is the documented mechanism for automatically applying updates. Ubuntu says security updates are enabled by default and the automatic update job runs daily by default. Confirm that the mechanism is active on the specific server, and monitor its logs so failures or packages awaiting action do not go unnoticed. Ubuntu automatic updates

Plan for restarts and reboots
Updates can require a service restart or a system reboot before a fix is fully in effect. Decide how those events are handled for the workload: automatic restarts may affect availability, while postponing them leaves updated components inactive until they are restarted. Include a process for identifying required reboots and scheduling them promptly.
Handle exceptions deliberately
Some workloads may need package exceptions or a controlled maintenance window. Keep exceptions narrow, documented, and reviewed; do not let operational convenience become an indefinite reason to skip security updates.
Patch image-based deployments too
Automatic updates inside a running instance are not the only valid maintenance path. If a deployment uses immutable or image-based systems, build and roll out refreshed images promptly when security fixes are available. The important outcome is timely patching, whether updates are applied on the host or through a managed rebuild process.

Reduce privileges and remove software you do not need
Use non-root accounts for routine work and reserve elevated privileges for administration. Give each account only the access needed for its job; the appropriate account and sudo policy depend on the workload and how administrators operate the server. Ubuntu’s security recommendations advise avoiding routine root use and removing packages that are not required. Ubuntu security introduction
- Review installed services and packages, and remove those the server does not need.
- Limit administrative accounts to intended operators and review access when roles change.
- Run applications under accounts suited to their specific workload instead of granting broad administrative access.
Fewer unnecessary components mean fewer services and interfaces to maintain. Least privilege also limits what a compromised account or application can do, although it does not by itself prevent compromise.
Allow only required network traffic
Ubuntu’s default firewall configuration tool is ufw, and Ubuntu documents that it is initially disabled. A host firewall should allow only the inbound services the server actually needs, with source restrictions where appropriate. Ubuntu firewall configuration

Check management access before enabling or tightening rules
Before changing firewall policy, identify the server’s required inbound services and confirm how administrators reach it. If you are configuring a remote machine, ensure the management path is allowed before enabling or tightening rules; otherwise, you may lock yourself out. Make changes through a recovery-capable console or a tested maintenance procedure when remote access is at risk.

Revisit them when services change, and remove allowances that are no longer needed. A host firewall reduces reachable network paths, but it does not replace patching, account controls, or application confinement.
Restrict and secure remote administration
Ubuntu recommends SSH for remote access and identifies OpenSSH as its common implementation. Limit remote administration to the intended administrators and apply an authentication policy appropriate to the server and its operating environment.

There is no single SSH configuration recipe established here for every server. Authentication requirements and compatible settings depend on the environment, so use the documentation for the installed release and verify access before closing an existing session or changing remote-access policy.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Confine applications with mandatory access control
Mandatory access control (MAC) adds restrictions on what an application can access beyond ordinary user and file permissions. Ubuntu uses AppArmor by default. Profiles define permitted behavior for applications, helping constrain a process if it is compromised. Ubuntu AppArmor documentation
Test profiles, then enforce them
AppArmor supports complain mode, which records policy violations without blocking them, and enforce mode, which applies the profile’s restrictions. Use complain mode to observe an application’s behavior while developing or adjusting a profile. Review audit messages and tailor the policy to the application; do not make a profile broadly permissive simply to silence alerts. Once the profile is suitable, enforce it.

- 【Reduce Safety Risks】Cable tray under desk keeps all plugs away from your kids, no more worry about tripping. Using 2 holes wire tray saves extra space, helps you easily cabling and wire protection. The mesh design is not easy to accumulate dust, but avoids safety accidents caused by messy wires.
Disabling confinement as a routine troubleshooting shortcut removes a useful layer. When a service fails under enforcement, investigate the specific denied access and adjust the profile only when the application genuinely needs that access.
AppArmor and SELinux are distribution-aware choices
AppArmor and SELinux use different policy models: AppArmor is pathname-based, while SELinux is label-based. Ubuntu uses AppArmor by default, and Ubuntu’s guidance says administrators who choose SELinux on Ubuntu should expect to handle policy development and maintenance themselves. Ubuntu AppArmor and SELinux overview
Do not transplant commands or policy assumptions between distributions. The installed distribution and release determine the supported MAC system, defaults, and maintenance expectations. Red Hat’s RHEL 8 security-hardening documentation is specific to that product and release; it should not be treated as universal Linux guidance. Red Hat Enterprise Linux 8 security hardening

Build a maintainable baseline
- Identify the platform and workload. Record the distribution and release, required services, administrator access path, and whether the system is updated in place or rebuilt from images.
- Establish patch operations. On Ubuntu, verify the documented unattended update path or arrange timely image rebuilds; monitor update outcomes and plan restarts and reboots.
- Review accounts and packages. Remove unneeded software and services, use non-root accounts for routine work, and keep elevated access narrowly scoped.
- Restrict network exposure. Define required inbound traffic and management reachability before changing host firewall rules.
- Apply application confinement. Use the MAC system supported by the distribution. For Ubuntu AppArmor profiles, observe behavior in complain mode, review audit messages, then enforce a policy tailored to the application.
- Reassess after changes. New services, workload changes, and release upgrades can alter what must be reachable or permitted. Review update status, firewall allowances, account access, and application profiles as part of ongoing administration.
