Cybersecurity & Privacy

Protecting your data and devices doesn’t have to be hard. These short guides make it simple.

Quick Navigation

Why it matters: Weak passwords are the easiest way attackers get in. A strong password is the foundation of account securityge

How to create a strong password

Rules for a strong password
      • Length matters: aim for 12+ characters (16+ for sensitive accounts).
      • Use a mix: uppercase, lowercase, numbers, and symbols.
      • Avoid reuse: every important account must have a unique password.
      • Avoid predictable info: names, birthdays, common words, or keyboard patterns.
      • Use passphrases: 3–5 random words (e.g., coffee-table-rainbow-89!).
Why it matters: 2FA adds a second barrier — even if someone gets your password, they likely can’t get past the second factor.

Setting up two-factor authentication (2FA)

Types of 2FA
    • Authenticator apps (TOTP): Google Authenticator, Authy, Microsoft Authenticator — recommended.
    • Hardware keys: YubiKey, Titan — strongest protection.
    • SMS codes: Better than nothing, but vulnerable to SIM swapping.
    • Email codes / push notifications: Varying security; push notifications from authentic apps are convenient.
How to enable
    1. Go to account Security settings → Two-factor authentication / 2-step verification.
    2. Choose Authenticator app or hardware key.
    3. Scan the QR code with your authenticator app, save backup recovery codes offline.
    4. Test by logging out and back in.
Best practices
    • Prefer authenticator apps or hardware keys over SMS.
    • Store recovery codes securely (password manager or printed safe).
    • Register more than one 2FA device if possible.

Common online scams and how to avoid them

Top scams
    • Phishing emails
    • Vishing (phone scams)
    • Smishing (SMS scams)
    • Tech support scams
    • Impersonation & social media scams
How to spot them
    • Urgent language demanding immediate action.
    • Mismatched sender email address or suspicious domains.
    • Links that don’t match visible text (hover to preview).
    • Unexpected attachments or downloads.
    • Requests for passwords, 2FA codes, or bank details.
What to do
    • Don’t click links — open site manually in a browser.
    • Verify sender via other channels.
    • Report phishing to your email provider and the impersonated company.
    • If you entered credentials, change password & enable 2FA immediately.

Guide to using a VPN for privacy

What a VPN does

Encrypts your internet connection and hides your IP from the sites you visit. Useful for privacy on public Wi‑Fi and bypassing geo‑blocks — not a silver bullet.

Choose a VPN provider

Look for no‑logs policy, strong encryption (AES‑256), WireGuard or OpenVPN support, good speed, and reputable audits (ExpressVPN, Mullvad, Proton VPN, NordVPN).

How to use safely
    • Use VPN on public Wi‑Fi or when you don’t want your ISP to see traffic.
    • Avoid free VPNs that log or sell your data.
    • Combine VPN with HTTPS websites (look for the padlock).
    • For banking, prefer home network + HTTPS; VPN helps but isn’t a substitute.

How to detect and remove spyware

Signs of spyware
    • Unexpected CPU, disk, or network activity.
    • Browser home/search engine changed or new toolbars.
    • Unexpected popups, new apps, or redirects.
    • Unusual outgoing network connections or battery drain.
Detection tools

MalwareBytes, HitmanPro, ESET Online Scanner, Kaspersky Virus Removal Tool. Autoruns (Sysinternals) and GlassWire for network monitoring.

Removal steps
    1. Disconnect from internet (optional).
    2. Boot into Safe Mode and run full scans with MalwareBytes + Defender.
    3. Use offline rescue disks if infection persists.
    4. Remove suspicious browser extensions and reset settings.
    5. Check Task Scheduler and Autoruns for persistence.
    6. Change important passwords from a clean device.
    7. Consider full OS reinstall if critical systems are compromised.
