The 90-Minute Security Sprint for Vibe Coders

This 90-minute sprint gives you a repeatable way to reduce risk every week without turning your team into a compliance machine.

The sprint agenda

1) 15 minutes: Attack-surface check

• List every internet-facing entry point: web app, API, admin panel, webhook endpoints.
• Confirm which endpoints are actually used.
• Remove stale routes and temporary debug paths.

2) 20 minutes: Headers and browser policy pass

Focus on fast wins with high impact:

• Set X-Content-Type-Options: nosniff
• Set X-Frame-Options: DENY (or use CSP frame-ancestors)
• Add a baseline Referrer-Policy
• Start with a report-only CSP before enforcing

This protects users against common client-side abuse with minimal engineering effort.

3) 20 minutes: Auth and session sanity checks

• Ensure session cookies are Secure, HttpOnly, SameSite=Lax or Strict
• Verify logout actually invalidates tokens
• Add short token lifetimes for privileged actions
• Confirm admin routes are role-gated on backend, not only hidden in UI

4) 20 minutes: Data exposure sweep

• Search for secrets in code, logs, and environment snapshots
• Remove verbose stack traces in production
• Sanitize user-generated content before rendering
• Check that backup exports are not publicly reachable

5) 15 minutes: Fix-forward commitment

Turn findings into execution immediately:

1. 1Create 3 tickets max
2. 2Assign owners now
3. 3Ship at least 1 fix today

This keeps the loop short and prevents security work from becoming a never-ending backlog.

A practical quality bar for fast teams

You do not need enterprise process to be secure. You need a predictable rhythm:

• Weekly 90-minute sprint
• Clear ownership
• Small, shippable controls

That is enough to move from reactive firefighting to controlled velocity.

What to measure

Track three lightweight metrics:

• Time to fix high-risk findings
• Number of public attack-surface endpoints
• Percentage of releases that include at least one security improvement

If these metrics improve over 4-6 weeks, your security posture is getting stronger in a measurable way.

Final takeaway

Vibe coding and security are not opposites. The right workflow makes them reinforce each other. Run this sprint every week and your team will ship fast with less fear, fewer incidents, and better confidence in production.
