Keep your server patched, before end-of-life deadlines leave you exposed

Server hardening and routine patching close the known, already-fixed holes that automated attack scripts look for every day. We update your server stack to supported releases and add layered protections (defence in depth), so one missed setting is not the only thing in the way.

Operating on obsolete software exposes your business to unpatched vulnerabilities. Official security maintenance for PHP 8.2 ends on 31 December 2026 (active support ended 31 December 2024), leaving installations without security updates. Ubuntu 22.04 LTS standard security maintenance ends in May 2027. Both dates checked on 26 October 2026 against php.net (supported versions) and ubuntu.com (release cycle).

If you need a quick fix for the critical php2shell vulnerability (CVE-2026-109618 and CVE-2026-109619), we offer a focused PHP update and compromise check for NZ$295. For full server hardening, we upgrade OS packages, enforce SSH key-only access, configure UFW firewall rules, deploy fail2ban intrusion prevention, verify TLS ciphers, and test backup integrity. Before we log in, the server owner gives written permission and SSH or control panel access. NullGlitch is a sole trader and not GST-registered, so no GST is added.

What We Handle

What’s included in Server Update & Hardening

Built around commercial clarity, faster delivery, and clean execution.

OS and PHP updates to supported versions

Upgrade Ubuntu and PHP stacks to active LTS and supported maintenance versions, closing known CVE vulnerabilities.

Supported PHP versions
Ubuntu LTS upgrades
Planned switchover window
Rollback snapshots taken

SSH key authentication and port security

Disable password authentication across SSH, enforce ED25519/RSA keys, and optionally change default ports to reduce automated noise.

No password guessing
Key-based access only
Root login disabled
Less automated login noise

UFW firewall and fail2ban deployment

Configure host firewalls to expose only required web ports, and set up fail2ban to automatically ban repeat offending IP addresses.

Port access lockdown
Automated IP bans
Rate-limiting rules
Protects against log flooding

Web server and PHP runtime lockdown

Harden Nginx, Apache, and PHP-FPM configurations to disable directory indexing, suppress server headers, and restrict dangerous functions.

No directory listings
Version headers removed
Upload folder execution off
PHP function restrictions

TLS cipher hardening and certificate check

Audit SSL/TLS configuration against modern security standards, enforce TLS 1.2/1.3, and verify automatic certificate renewal.

Modern TLS settings
Strong cipher suites
Auto-renewing certificates
Enforced HTTPS redirects

Backup verification and restore testing

Confirm that automated off-site backups run on schedule, and perform an actual test restore to verify data can be recovered.

Off-site backup check
Test restore verification
Disaster recovery readiness
Database dump integrity
Delivery

How the project runs

Clear phases, no mystery, and no padded process theatre.

01

Audit & Snapshot

With the owner's written permission, review packages and PHP, then take a snapshot.

02

OS & PHP Upgrade

Upgrade core packages and PHP to supported releases, testing compatibility.

03

Security Hardening

Configure SSH key-only access, UFW firewall, fail2ban, and web server rules.

04

Backup Test & Report

Verify backups with a test restore and provide complete written documentation.

FAQ

Questions before you commit

Straight answers on timing, scope, support, and what happens after launch.

In addition to the critical php2shell vulnerability (CVE-2026-109618 and CVE-2026-109619) disclosed on 21 October 2026, PHP 8.2 reaches its official end of life for security fixes on 31 December 2026. Running unsupported PHP means future vulnerabilities will not receive security patches. Checked on 26 October 2026 against php.net supported versions.
