### **Understanding Security and Compliance in E-Commerce**
**Security** in e-commerce refers to the measures taken to protect online transactions and data from cyber threats. This includes safeguarding customer information, ensuring the integrity of transactions, and protecting the platform from attacks like hacking, phishing, and malware.
**Compliance** involves adhering to laws, regulations, and standards that govern how businesses collect, store, and use data. Key regulations include the **General Data Protection Regulation (GDPR)**, **California Consumer Privacy Act (CCPA)**, and industry standards like the **Payment Card Industry Data Security Standard (PCI DSS)**.
Failure in either area can lead to severe financial penalties, legal repercussions, and lasting damage to a company's reputation.
