Protect Yourself

Every time you visit a website, your device asks a DNS server for the address. By default, this goes through your ISP, who can log every site you visit. Advertisers and malicious sites use DNS to track you and serve harmful content.

A DNS sinkhole like Pi-hole acts as your network's bouncer. It intercepts DNS requests and blocks known advertising, tracking, and malicious domains before they ever reach your devices. One Pi-hole protects your entire network.

1. 1.Set up a Raspberry Pi or use an old computer
2. 2.Install Pi-hole (free, open-source)
3. 3.Point your router's DNS to your Pi-hole
4. 4.All devices on your network are now protected

Your smart TV, security cameras, and IoT devices are often poorly secured. If compromised, they can access everything on your network - your computers, phones, and personal files. One weak link breaks the whole chain.

Network segmentation creates separate zones in your home network. Your IoT devices live on one network, your personal devices on another. Even if your smart fridge gets hacked, it can't reach your laptop.

1. 1.Access your router's admin panel
2. 2.Create a separate guest network for IoT devices
3. 3.Or set up VLANs if your router supports them
4. 4.Keep sensitive devices on the main, secured network

When you store photos on Google or iCloud, you're trusting corporations with your most personal data. They can scan it, use it for AI training, share it with authorities, or lose it in a breach. You have no real control.

A Network Attached Storage (NAS) device is your personal cloud server. It sits in your home, holds your files, and syncs across your devices - just like Dropbox or iCloud, but you own it. No monthly fees, no data mining.

1. 1.Choose a NAS device (Synology, QNAP, or DIY)
2. 2.Install hard drives for storage
3. 3.Set up sync apps on your phone and computer
4. 4.Enable remote access for anywhere availability

If you reuse passwords, one breach exposes all your accounts. Hackers buy leaked password databases and automatically try them everywhere. 'Password123' gets cracked in milliseconds. Even 'complex' passwords you can remember aren't strong enough.

A password manager generates and stores unique, random passwords for every account. You remember one master password; it handles the rest. Combined with two-factor authentication (2FA), your accounts become extremely difficult to breach.

1. 1.Choose a password manager (Bitwarden is free and open-source)
2. 2.Import your existing passwords
3. 3.Generate new, unique passwords for critical accounts
4. 4.Enable 2FA everywhere it's offered (use an app, not SMS)

Regular SMS and email can be intercepted, read by providers, and subpoenaed by authorities. Your ISP can see every unencrypted website you visit. In an era of mass surveillance, privacy requires deliberate action.

End-to-end encryption means only you and your recipient can read messages - not the service provider, not hackers, not governments. A VPN encrypts your internet traffic, hiding what you do online from your ISP and network snoopers.

1. 1.Switch to Signal for messaging (free, easy)
2. 2.Use a VPN when on public WiFi or for general privacy
3. 3.Consider ProtonMail for encrypted email
4. 4.Enable HTTPS-only mode in your browser

Every app, service, and website collects data about you. This data gets breached, sold to brokers, and used to build detailed profiles. The more data exists about you, the more vulnerable you are to identity theft, scams, and manipulation.

Data minimization means reducing your digital footprint. Delete unused accounts, opt out of data collection, use privacy-respecting alternatives, and think twice before giving out personal information.

1. 1.Audit your accounts - delete what you don't use
2. 2.Opt out of data broker sites (use a service or DIY)
3. 3.Review app permissions on your phone
4. 4.Use temporary email addresses for signups

AI can now clone voices from seconds of audio, create convincing fake videos, and write personalized phishing emails. Scammers use AI to impersonate family members, CEOs, and trusted institutions. The era of 'seeing is believing' is over.

Awareness is your best defense. Verify unexpected requests through a different channel. Be skeptical of urgent demands for money or information. Establish family code words for emergencies. Trust your instincts when something feels off.

1. 1.Create a family code word for emergency verification
2. 2.Always verify unusual requests via a different channel (call back on a known number)
3. 3.Be extra skeptical of urgent financial requests
4. 4.Learn to spot AI-generated content (unnatural movements, audio glitches)
