Cybersecurity best practices for small businesses
Most security incidents occur due to weak identity protection, phishing, unpatched devices, or missing backups. These practices significantly reduce risk.
Require MFA for Microsoft 365, VPN access, and administrator accounts.
Configure SPF, DKIM, and DMARC to reduce impersonation and phishing risk.
Keep devices patched, encrypted, and protected with endpoint security tools.
Educate employees to detect suspicious emails, links, and attachments.
Limit administrative privileges and enforce least-privilege access.
Ensure backups are tested and recovery procedures are documented.
