Network Security

Network security

Is the protection of your digital infrastructure—your Wi-Fi, routers, devices, data traffic, and everything connected to the internet—from unauthorized access, attacks, or misuse.

This is a BIG ONE. Not only is it important to keep your computer protected…but what about your network? How do you do it? What is needed to do this? How can I check to see the status of anything weird going on? These are just some of the questions we receive.

Why Network Security Is Critical in 2025

🔺 New Threats:

• AI-generated phishing & deepfake scams

• IoT device exploits (smart TVs, thermostats, etc.)

• Ransomware gangs targeting home networks and small businesses

• Credential stuffing with stolen passwords from breaches

🏠 Home networks are no longer “safe by default”:

Even regular users face:

• Router hijacks

• DNS spoofing

• Device snooping (e.g. smart speakers, security cams)

🧰 Key Elements of Network Security (2025)

1. 🧱 Firewall

• Built into most routers and operating systems.

• Use hardware firewalls for businesses; software ones for personal devices.

• Pro tip: Enable “stealth mode” or similar options in your router.

---

2. 🔑 Strong Wi-Fi Security

• Use WPA3 encryption (or WPA2 if WPA3 isn’t available).

• Rename your SSID (avoid using personal info).

• Disable WPS (Wi-Fi Protected Setup).

• Use a unique, long Wi-Fi password.

---

3. 📡 Router Security

• Change default username & password immediately.

• Keep router firmware updated.

• Disable remote management unless needed.

• Enable guest network for visitors or IoT devices.

• Consider replacing old routers (pre-2020) that lack modern protections.

---

4. 🧠 Device Isolation

• Keep IoT devices (smart lights, TVs, etc.) on a separate VLAN or guest network.

• Segment work devices from entertainment ones.

---

5. 🔍 Network Monitoring

• Use apps like:

  • Fing (to scan your network for unknown devices)

  • GlassWire (traffic monitoring and alerts)

  • Pi-hole (network-wide ad/malware blocker)

---

6. 🔐 VPNs & Encryption

• Use a trusted VPN on public networks.

• For businesses, use site-to-site or endpoint VPNs.

• Avoid free VPNs; they often sell your data.

---

7. 📱 Device Hygiene

• Use antivirus/antimalware on all major devices.

• Keep OS and apps updated.

• Enable 2FA (two-factor authentication) everywhere.
