🔐 Smart IoT Buying Guide + Post-Purchase Security Checklist
Before purchasing any IoT (smart) device, security should never be an afterthought — it should be part of your decision.
🛒 Before You Buy – Ask These Questions:
🔐 Secure by Design
• Does it force you to change default passwords?
• Does it support strong passwords or multi-factor authentication (MFA)?
• Are security features enabled by default?
🔄 Updates & Support
• Does the vendor provide regular firmware/security updates?
• How long will the device be supported?
📊 Data Transparency
• What data is being collected?
• Where is it stored (local/cloud)?
• Is your data shared with third parties?
🌐 Reputation Matters
• Is the brand trusted and known for security?
• Are there known vulnerabilities or past breaches?
⚠️ Network Risk
One insecure device can expose your entire home or workplace network.
⚙️ After You Buy – MUST-DO Security Steps:
🛠️ 1. Change Default Credentials Immediately
Never keep factory usernames/passwords.
🔐 2. Use Strong, Unique Passwords
Avoid reusing passwords across devices.
📲 3. Enable MFA (If Available)
Adds an extra layer of protection.
🔄 4. Update Firmware Right Away
Check for updates during setup — and keep auto-updates ON.
📡 5. Place Devices on a Separate Network (VLAN/Guest Wi-Fi)
Keep IoT devices isolated from your main network (especially important for workplaces).
🚫 6. Disable Unused Features
Turn off remote access, UPnP, or services you don’t need.
🔍 7. Monitor Device Activity
Watch for unusual traffic or behaviour.
☁️ 8. Review Privacy Settings
Limit unnecessary data sharing.
🗑️ 9. Remove/Reset Before Disposal or Resale
Always factory reset before giving away or selling.
