IT Security Best Practices for Ghana Companies

Cyber incidents in West Africa are rising—payment fraud, account takeovers, ransomware, and deepfake-driven scams. Here is the minimum security baseline we deploy for clients in Ghana.

Identity and access

• MFA everywhere (hardware keys for admins); SSO for staff apps.
• Role-based access; least privilege; quarterly access reviews.
• Offboarding checklist: disable accounts, rotate keys, reclaim devices the same day.

Network and cloud perimeter

• Use private networks/VPCs; no public SSH/RDP. Bastion or SSM only.
• WAF + rate limiting; DDoS protections on public endpoints.
• Segmentation: prod/stage/dev isolated; separate data stores for PII.

Endpoints and office

• Full-disk encryption, EDR, OS patching, and automatic screen lock.
• Secure Wi‑Fi: WPA3, unique credentials, guest networks for visitors.
• Backups for key laptops; enforce device inventory and labeling.

Application and data security

• Secrets in vaults, never in code or chat; rotate keys.
• Use parameterized queries; enable HTTPS everywhere; HSTS + TLS 1.2+.
• Logins: brute-force protection, suspicious IP alerts, device fingerprinting for payments.
• Encrypt PII at rest; separate encryption keys; back up and test restores quarterly.

Payments and fintech-specific controls

• Tokenize cards; never store CVV; use PCI DSS compliant gateways.
• Reconcile MoMo and card webhooks with idempotency + retries.
• Monitor high-risk behaviors: velocity, BIN country mismatches, device changes.

Incident response

• Define roles (incident lead, comms, forensics, business owner).
• Run tabletop drills quarterly: ransomware, data leak, payment fraud.
• Prepare customer comms templates; know regulatory contacts.
• Retain logs centrally; keep timelines for post-incident review.

Security awareness

• Quarterly training; monthly phishing simulations with feedback.
• Clear BYOD rules; mandate updates and mobile device management where possible.
• Report channel (Slack/Teams/Email) for suspicious activity; celebrate quick reporting.

• Security audit and remediation roadmap aligned to business risk.
• Secure Office bundle: MFA, SSO, device hardening, backups, and monitoring.
• Payment and web app hardening; WAF + SIEM + alerting.
• Incident response readiness and on-call support.
