Security doesn't always start with an expensive enterprise firewall or SOC platform. For small businesses and lean tech teams, identity theft, unpatched workstations, and misconfigured access permissions account for the vast majority of security incidents.
Here is a practical, non-fluff cyber hygiene checklist to harden your workspace today.
1. Identity & Access Management (IAM) Basics
Enforce MFA & Password Managers: Ban reused passwords across services. Force TOTP-based MFA on corporate Google/Microsoft accounts.
Kill Shared Accounts: Every team member gets their own account. Shared credentials make auditing impossible when suspicious DB queries or file deletions happen.
Enforce Least Privilege: Developers and end-users shouldn't run local workstation sessions as local Admins. Separate daily user accounts from privileged admin credentials.
2. Workstation Hardening & Network Segmentation
Full Disk Encryption: Enable BitLocker (Windows) or FileVault (macOS) on all laptops. Auto-lock screens after 3–5 minutes of inactivity.
Network Isolation: Isolate IoT devices (printers, smart TVs, cameras) and guest Wi-Fi networks onto a separate VLAN away from internal file servers and staging databases.
3. Backup & Patch Pipeline
3-2-1 Backup Rule: Keep 3 copies of vital data on 2 different media types, with 1 copy stored offsite/immutable cloud storage.
Patch Management: Enable auto-updates for OS and third-party software to close known CVEs before exploit scripts find them.

4. Incident Response & Outsourcing
Don't wait for a Ransomware infection to write your incident playbook. Establish clear escalation paths for compromised accounts and isolate infected machines immediately from the local network.
