In a world powered by APIs, waiting for an attack is waiting too long. Business logic risks like Broken Object Level Authorization (BOLA) don’t announce themselves with obvious signatures or malware. They hide in plain sight within normal-looking traffic and by the time a BOLA exploit turns into a breach, the damage is done.
Imperva’s unified API security platform helps you close the loop: expose BOLA risks early, contain abuse through smart thresholds, and mitigate threats with precision.
When One Vulnerable API Endpoint Changed Everything
It’s Black Friday. Your e‑commerce site is flooded. Amid the chaos, a crafted API call tweaks a user‑ID parameter and silently spills over thousands of customer records. No malware, no brute‑force. Just logic gaps your security stack never saw.
That’s BOLA—a vulnerability in your business logic, not in your code. By the time you see “attack” alerts, damage is done. Instead, you need to detect the risk long before an exploit ever occurs.
The Real BOLA Problem: Not the Attack, But the Hidden Risk
What makes BOLA dangerous?
- It exploits normal-looking API traffic.
- It has no attack signature, no CVE, and no universal pattern.
- It varies by app, by API — no one-size-fits-all rule can catch it.
That’s why the right question isn’t “How do we stop BOLA attacks?” — it’s “How do we expose BOLA risk before attackers can exploit it?”
Imperva’s Proactive, Risk-First Approach
1. Discover and Map API Risk
- Continuous API Discovery
Imperva automatically maps all APIs — public, private, shadow, and deprecated, so no endpoint flies under the radar. - Data Classification
Sensitive fields (PII, financial, health data) are tagged so critical APIs rise to the top of your focus list.
2. Score and Prioritize BOLA Risk
- Schema & Authorization Checks
Identify endpoints missing object-level controls. - Behavioral Profiling
Spot one-to-one object relationships or unusual patterns that signal BOLA potential. - Dynamic Risk Scoring
APIs get composite BOLA-risk scores — so teams know where to focus on remediation.
No waiting for exploits — you see the risk landscape now.
3. Fix Vulnerabilities and Define Containment Thresholds
- Guided Remediation
Get prescriptive actions: tighten access logic, validate parameters, improve authorization checks. - Threshold-Based Containment
Set sensible limits on object access (e.g., how many unique IDs a user can query). - Early Warning Alerts
Imperva notifies you when thresholds are exceeded — so you can review and act before enforcing hard blocks.
Early warnings protect user experience while containing risk.
4. Enable Targeted Detection and Response
- Threshold-Driven Detection
Live traffic is monitored for threshold breaches and logic abuse patterns. - Flexible Response Options
Choose from alert → throttle → block or integrate with SOAR playbooks for automated response. - Detailed Audit Logging
Every event is logged: object ID, token, IP, session — ensuring forensic clarity and compliance reporting.
Real-time mitigation, but only after proactive exposure and containment.
Proactive vs. Reactive: Why This Matters
| Proactive Risk-First | Reactive Attack-First |
| Discover risk and score endpoints | Wait for exploit or alert to surface |
| Remediate vulnerabilities early | Patch in crisis mode after breach |
| Contain with thresholds & alerts | Blunt blocking, higher false positives |
| Tune based on real traffic patterns | Static rules, slow to adapt |
Proactive API Security Checklist
- Discover & map all APIs
- Classify sensitive data
- Run hybrid risk analysis
- Remediate logic flaws
- Define smart thresholds
- Monitor and adjust thresholds
- Enable targeted detection & response
- Review and tune continuously
Business Impact: What Closing the Loop Delivers
- Reduced Risk: Logic flaws exposed and fixed before exploitation.
- Balanced UX: Early alerts avoid user disruption; enforcement is precise.
- Faster Remediation: Guided fixes + audit trails = faster MTTR.
- Stronger Compliance: Full API inventory, risk history, and event logs at your fingertips.
- High ROI: Leverages existing WAF investments, minimal dev effort, rapid protection.
Why Imperva’s Unified Approach Stands Out
| Phase | Imperva Unified Platform | Point Solutions |
| Risk Visibility | Continuous discovery + hybrid scoring | Manual audits, fragmented tools |
| Vulnerability Remediation | Prescriptive, in-console guidance | Left to SecOps/dev to figure out |
| Risk Containment | Thresholds + early alerts | All-or-nothing blocking |
| Detection & Response | Contextual, threshold-triggered actions | Signature-only, high false positives |
| Continuous Improvement | Analytics feed tuning | Static rule sets |
