Patch Management
Patch management keeps systems secure, stable, and reliably up to date.
For developers: it’s a process.
For businesses: protection against known vulnerabilities.
For auditors: a requirement.
And for us: a natural part of responsible IT operations.
Why is patch management important?
Security flaws emerge constantly – from new threats and long-standing bugs.
Many attacks don’t exploit “zero days” but use known vulnerabilities.
An unpatched system isn’t a technical glitch – it’s a calculated risk.
- Exploitation of known vulnerabilities as an entry point has nearly tripled and contributed to 14% of breaches. (Verizon, 2024)
- 28% of successful cyberattacks exploit known vulnerabilities, while 24% rely on zero-day or unknown flaws. (ENISA, 2024)
- On average, organizations take 55 days to patch half of all critical vulnerabilities after fixes are available. (Foster, 2024)
- GDPR (Article 32) explicitly requires the use of “state of the art” measures – including timely patching of known issues. (GDPR, 2016)
What does patch management involve?
It’s more than just “applying updates”:
- Monitoring for new patches and advisories
- Assessment & approval based on severity
- Testing in staging environments
- Planned maintenance windows – aligned with operations
- Documentation & logging – for compliance and auditability
The goal: introduce updates safely – with no surprises.
Smart automation – with control
Automatic updates are helpful – but not always risk-free.
Our approach:
- Security patches are applied quickly and systematically
- Feature updates are rolled out in controlled windows
- Rollback strategies are in place – just in case
Speed without control isn’t a benefit.
How we handle patch management at RiKuWe
Patch management is part of our standard operating procedures:
- We evaluate, prioritize, and document updates
- Critical patches are applied automatically – securely and transparently
- Clients stay informed – without having to take action themselves
No “let’s hope nothing breaks.”
Just a system that takes care of itself.
Patch management with RiKuWe
We don't patch "at some point" — we patch within a structured operating model:
-
Patch management as part of managed operations
Kubernetes clusters are updated regularly — with prior review, compatibility analysis, and documented changes. -
Managed databases with update cycles
PostgreSQL, MariaDB & Co. are maintained by RiKuWe: security updates, minor releases and, on request, major versions with migration support. -
Central components like cert-manager & WireGuard
Base services such as VPN, DNS, or certificate management get automatic or agreed updates too — traceable, documented, and with rollback options. -
Monitoring & alerting for pending patches
We don't just detect missing updates — we act on them. Alertmanager and Prometheus track security and stability issues automatically. -
Quickstart: infrastructure health check
Not sure how current your systems are? We review your environment for pending patches and risks, and give you concrete recommendations.
Frequently Asked Questions
What is patch management?
Patch management is the structured process of keeping systems secure, stable, and up to date – including evaluation, approval, testing, and documentation.
Why isn’t auto-updating enough?
Auto-updates are helpful but risky – e.g., due to incompatibilities or lack of oversight. Professional patch management reviews, prioritizes, and logs every update.
How often should systems be patched?
Critical security patches should be applied as soon as possible – often within a few days. Feature updates follow scheduled maintenance cycles, usually weekly or monthly.
What if a patch causes issues?
Good patch management includes rollback strategies – e.g., snapshots or backups. For us, that’s part of every update plan.
Is patch management important for small businesses too?
Absolutely. Smaller businesses are often less resilient to outages or attacks. Patch management protects against known threats and ensures reliable operations.
