2. Data Security & Protection

2.1 Data Classification & Handling

• Level 1 (Highly Sensitive): Full payment card data (PCI DSS scope), government-issued ID numbers, biometric data. Requires strongest encryption (AES-256 at rest, TLS 1.3+ in transit) and strictest access controls.

• Level 2 (Sensitive): Customer names combined with physical address, email, phone number, order history, partial payment data (last 4 digits). Encrypted at rest and in transit, with role-based access.

• Level 3 (Internal): Operational data, inventory logs, marketing analytics. Protected by access controls and network segmentation.

• Level 4 (Public): Public website content, product descriptions. Minimal protection required.

2.2 Data Encryption

• In Transit: All data transmitted between user browsers/apps and our servers is encrypted using TLS 1.3 (or latest secure protocol). HTTPS is enforced site-wide (HSTS).

• At Rest: All databases, file stores, and backups containing Level 1 & 2 data are encrypted using AES-256 or equivalent industry-standard encryption.

• Payment Data: We are PCI DSS compliant. We do not store full credit card numbers, CVV codes, or magnetic stripe data. Payment processing is delegated to PCI-DSS Level 1 certified payment gateways (e.g., Stripe, Adyen, Braintree).

2.3 Data Retention & Disposal

• We retain personal data only as long as necessary to fulfill the purposes outlined in our Privacy Policy, or as required by law.

• Secure deletion methods (cryptographic erasure for cloud, physical destruction for hardware) are used for data disposal.

3. Platform & Infrastructure Security

3.1 Network Security

• Firewalls & WAF: Network-level and Web Application Firewalls (WAF) are deployed to monitor and filter malicious traffic, prevent DDoS attacks, and block common web exploits (e.g., SQLi, XSS).

• Intrusion Detection/Prevention Systems (IDS/IPS): Monitor network traffic for suspicious activity and known threat patterns.

• Network Segmentation: Critical systems (e.g., payment processing, database servers) are isolated in separate network segments/VPCs.

• DDoS Mitigation: We utilize cloud-based DDoS protection services to absorb and mitigate large-scale attacks.

3.2 Server & Endpoint Security

• Hardening: All servers follow security hardening guidelines (disabling unnecessary services, using SSH keys).

• Patch Management: A rigorous schedule is maintained for applying security patches to operating systems, applications, and dependencies within 30 days of critical patch release.

• Endpoint Protection: All company-managed devices (laptops, workstations) have mandatory endpoint detection and response (EDR) software, disk encryption, and screen lock policies.

• Cloud Security: We leverage the shared responsibility model with our Cloud Service Provider (e.g., AWS, GCP, Azure), implementing security groups, IAM roles, and continuous configuration monitoring.

3.3 Vulnerability Management

• Regular automated vulnerability scans are performed on our web applications and networks.

• We engage with reputable third-party security firms for annual Penetration Testing and code reviews.

• A responsible Vulnerability Disclosure/Bug Bounty program is in place to encourage external researchers to report security issues.

4. Access Control & Identity Management

4.1 Principle of Least Privilege
Access to systems and data is granted on a need-to-know basis. Regular access reviews are conducted quarterly to revoke unnecessary permissions.

4.2 Authentication

• Multi-Factor Authentication (MFA): Mandatory for all administrative accounts, developer access, and any system handling sensitive data.

• Strong Password Policy: Enforces minimum length (12+ characters), complexity, and prevents password reuse. Passwords are hashed and salted in databases.

• Single Sign-On (SSO): Implemented where possible for internal systems to centralize access control.

4.3 Session Management

• Secure, random session tokens are used.

• Sessions timeout after a period of inactivity (e.g., 15 minutes for admin panels).

• "Remember me" functionality does not apply to sensitive areas.

---

5. Application Security (AppSec)

5.1 Secure Development Lifecycle (SDLC)
Security requirements are integrated from the design phase. Code undergoes peer review and automated static/dynamic application security testing (SAST/DAST) before deployment.

5.2 Common Threat Protections
Our applications are built to mitigate OWASP Top 10 risks, including:

• Input validation and output encoding to prevent injection and XSS.

• Protection against Cross-Site Request Forgery (CSRF) using anti-CSRF tokens.

• Secure error handling that does not leak system information.

• Rate limiting and account lockouts to prevent brute-force attacks.

5.3 Third-Party Dependency Management
We actively monitor and update third-party libraries, frameworks, and plugins. An automated software composition analysis (SCA) tool is used to identify known vulnerabilities in dependencies.

6. Incident Response & Business Continuity

6.1 Security Incident Response Plan (SIRP)

• Team: A designated Security Incident Response Team (SIRT) is established.

• Process: Defined procedures for Identification, Containment, Eradication, Recovery, and Lessons Learned (Post-Incident Review).

• Communication: Clear protocols for internal communication and, if necessary, regulatory/consumer notification as mandated by law (e.g., 72-hour GDPR breach notification).

6.2 Backups & Recovery

• Regular Backups: All critical data is backed up automatically and encrypted.

• Off-Site Storage: Backups are stored in a geographically separate location from primary data.

• Testing: Backup restoration procedures are tested at least semi-annually to ensure viability.

6.3 Business Continuity & Disaster Recovery (BC/DR)
A documented BC/DR plan exists to maintain or quickly resume critical business functions in the event of a major disruption (cyber-attack, natural disaster).

---

7. Third-Party & Supply Chain Security

• Vendor Risk Assessment: All third-party vendors, especially those with access to our data or systems (e.g., logistics, CRM, analytics), undergo a security review prior to engagement.

• Contracts: Data Processing Agreements (DPAs) and clauses specifying security requirements are included in contracts.

• Monitoring: We monitor the security posture of key vendors and require notification of any security incidents affecting our shared data.

---

8. Compliance & Audit

• We undergo regular internal and external security audits.

• We track and strive to comply with relevant regulations in our operating jurisdictions.

• Audit logs are maintained for all critical systems (access, changes, transactions) and retained for at least one year to support investigations and compliance needs.

---

9. User Security Responsibilities & Guidance

• We provide clear guidance to customers on creating strong passwords, recognizing phishing attempts, and securing their own accounts.

• We encourage users to enable account-level MFA where offered.

• Our Privacy Policy clearly explains how we collect, use, and protect user data.

---

10. Policy Governance

• This policy is owned and reviewed annually by the [Chief Technology Officer / Head of Security].

• All employees and contractors are required to read, acknowledge, and adhere to this policy and associated security procedures.

• Violations of this policy may result in disciplinary action, up to and including termination of employment or contracts.
