Practical Information Security Basics for Small Engineering Teams
Written by NsisongLabs Team on November 28, 2024
Security can feel overwhelming when you read compliance checklists and breach headlines.
For most growing teams, the right question is: What few habits give us the biggest reduction in risk right now?
1. Lock down access to production
Decide clearly:
- Who can log into production servers and dashboards.
- Who can run database queries against live data.
- Who can change DNS, cloud accounts, and critical secrets.
Then:
- Use SSO where possible.
- Require MFA for admin accounts.
- Remove access when people change roles or leave, as part of a checklist.
2. Manage secrets like they are production data
API keys, database passwords, and signing keys deserve the same care as customer records.
- Keep them out of source control.
- Use a secrets manager or managed parameter store where possible.
- Rotate critical secrets on a schedule and after any incident.
If rotating a secret feels scary, treat that as a design bug to fix.
3. Patch and update as a routine, not a project
Unpatched dependencies and servers are still one of the most common real-world attack paths.
Set up:
- Dependabot / Renovate or similar for libraries.
- A monthly or quarterly patch window for OS and platform updates.
- A simple smoke test suite you can run after updates.
The goal: updating is boring and repeatable, not an emergency.
4. Log enough to investigate incidents
You don’t need full-blown SIEM on day one, but you do need:
- Centralized application and access logs.
- Retention long enough to investigate slow-moving issues.
- Basic alerts for suspicious patterns (many failed logins, unexpected admin actions).
When something strange happens, your team should be able to reconstruct the story.
5. Train people, not just systems
Most breaches still involve humans making rushed decisions.
Spend a few hours per quarter on:
- Phishing awareness and safe password behavior.
- How to report a suspected incident quickly.
- What not to do in a panic (e.g. deleting logs).
Security is never “done”, but these basics put your team in a far stronger position while you grow.
