## What you need to know

### What is ecommerce application security?

Ecommerce application security protects the store's software and its development lifecycle from design, coding, configuration and dependency weaknesses that attackers can exploit.

### Why should ecommerce software be kept updated?

Updates correct known vulnerabilities, compatibility failures, and defects. Unsupported software leaves public weaknesses available after fixes exist elsewhere.

### How do outdated plugins create security risk?

Outdated plugins may contain known exploitable code, weak dependencies, or abandoned integrations with broad access. One plugin can expose the wider store.

### What is vulnerability management?

Vulnerability management is the continuous process of discovering, evaluating, prioritizing, fixing, and verifying security weaknesses across systems and providers.

### How often should security updates be applied?

Apply actively exploited and critical updates promptly under an emergency process; schedule lower-risk updates according to exposure and operational impact. Test and verify every deployment.

### What is secure software development?

Secure software development includes threat-aware design, safe coding, review, dependency control, testing, protected deployment, and maintenance throughout the product lifecycle.

### Why should security testing happen before release?

Pre-release testing finds authorization, input, secret, and configuration failures before customers and attackers encounter them. It complements, not replaces, secure design and review.

### How should discovered vulnerabilities be prioritized?

Prioritize by exploitability, exposure, affected data and privileges, customer impact and available compensating controls, not severity score alone. Track a verified owner and deadline.

### A quick store check

Review supported versions, dependency alerts, vulnerability priorities, pre-release tests and emergency update procedure.

## Frequently asked questions

### Can vulnerability scanning replace penetration testing?

No. Automated scanning and expert testing find different classes of weakness, and both depend on secure design.

### Should a low-severity issue be ignored forever?

No. Record ownership and reassess it when exposure, exploitability or system importance changes.
