⚙️ Setup Phase

The first 30 minutes with a device are critical. Configure biometrics, encryption, and accounts correctly from day one.

🛠️ Maintenance

Security is a habit. Regular updates, scanning for malware, and weekly reboots keep you safe.

💼 For SMEs

Understanding MDM (Mobile Device Management) and BYOD (Bring Your Own Device) policies.

Initial Setup: The Foundation

🔐 Auth & Access

  • Alphanumeric Passcode: 6 digits are now easily brute-forced. Use a mix of letters and numbers (e.g., 8+ characters).
  • Biometrics: Enable FaceID or Fingerprint for convenience and security.
  • App-Based MFA: Do not use SMS for 2-Factor Authentication (Sim Swapping risk). Use an app like Google Authenticator.

🛡️ Software & Encryption

  • Encryption: Ensure full-disk encryption is active (Default on modern phones).
  • Remote Wipe: Setup "Find My" (iOS) or "Find My Device" (Android) immediately.
  • Anti-Malware: Highly recommended for Android. (iOS is sandboxed, so focus on web filters there).

📶 Network & Privacy

  • VPN: Install a VPN for using public Wi-Fi (coffee shops, airports).
  • Permissions: Deny unnecessary permissions. A Flashlight app does NOT need your Contacts.
  • Backups: Enable encrypted cloud backups so you don't hesitate to "Remote Wipe" if lost.

Ongoing Maintenance: Daily Habits

🔄 Updates & Reboots

The Weekly Reboot: Restart your phone once a week. This clears temporary memory and breaks non-persistent spyware (like commercial surveillance tools).

📥 App Hygiene

Only download apps from official stores (App Store, Google Play).
Sideloading (installing from websites) is the #1 way phones get infected.

🧠 "Quishing" & Smishing

Quishing: Malicious QR codes in emails or on parking meters. They bypass email filters. Inspect the URL after scanning before you click!

Understanding MDM & BYOD

For businesses (SMEs), managing devices is a balance between security and flexibility.

The Reins

MDM (Mobile Device Management)

Imagine your device is a wild horse. MDM is the reins. It is software that allows IT admins to control, secure, and monitor devices remotely.

Functions:
✔ Remote Wipe (if stolen)
✔ Separate Work/Personal Data
✔ Enforce Password Rules
The Policy

BYOD (Bring Your Own Device)

Employees use their personal phones for work. Convenient, but risky without rules (Policy) or "Containerization" software.

Pros & Cons:
+ Saves company hardware costs
+ Employee comfort
- Risk of data leakage

Common MDM Software
