Security
Learn about cybersecurity best practices, tools, and techniques to protect your data and systems.
Cybersecurity Is Everyone's Responsibility
Security breaches make headlines, but most successful attacks exploit basic weaknesses: reused passwords, unpatched software, misconfigured servers, and human error. The good news is that a relatively small set of best practices - strong authentication, timely updates, encrypted communications, and user awareness - blocks the vast majority of threats. Security is not a product you buy; it is a practice you maintain.
Wizard Tech Services integrates security into every project we deliver, from web applications built with OWASP best practices to PC setups configured with disk encryption and secure boot. We can also audit your existing infrastructure and recommend targeted improvements.
Password Hygiene
Use a password manager to generate a unique, random password for every account. Enable multi-factor authentication wherever it is available - hardware security keys provide the strongest protection, followed by authenticator apps. Never reuse passwords across services.
Keep Software Updated
Most exploited vulnerabilities have patches available at the time of attack. Enable automatic updates for your OS and browser, review dependency updates for your projects weekly, and subscribe to security advisories for the software you rely on.
Encryption transforms readable data into ciphertext only authorized parties can decrypt. Covers AES-256 for data at rest, RSA/ECC for key exchange, TLS/SSL for data in transit, and full-disk tools like BitLocker and LUKS.
Cyber threats range from mass phishing and ransomware to targeted social engineering and zero-days. Recognize malicious emails, configure firewalls and endpoint detection, and build an incident response plan for when breaches occur.
Passwords alone are no longer enough. Explore MFA with TOTP apps and YubiKey hardware keys, SSO via SAML and OIDC, passkeys for passwordless login, and OAuth 2.0 flows. Covers secure session management and token rotation.
Privacy is a right and increasingly a legal requirement. Understand GDPR and CCPA compliance, data minimization, browser tracker blockers, and privacy-respecting alternatives like ProtonMail, Signal, and DuckDuckGo.
The OWASP Top 10 defines the most critical web security risks. Understand how SQL injection, XSS, and CSRF attacks work, how to prevent them in your code, and how to track new threats via CVE databases.
The right tools make security proactive. Explore vulnerability scanners (Nessus, OpenVAS), pen-testing frameworks (Burp Suite, OWASP ZAP), secrets managers (Vault), SIEM platforms, and password managers (Bitwarden, 1Password).
Authentication
Authentication methods and protocols for verifying identity and managing secure access.
Adds extra verification layers beyond passwords using TOTP codes, SMS, or push notifications to prove identity.
Key Features:
- TOTP apps like Google Authenticator and Authy
- SMS and email-based one-time codes
- Push-based approval on trusted devices
- Dramatically reduces account compromise risk
Physical devices like YubiKey that provide phishing-resistant authentication using the FIDO2 protocol.
Key Features:
- YubiKey supports FIDO2, OTP, and smart card
- Phishing-resistant - bound to origin domain
- No batteries or network connection needed
- Works with major services (Google, Microsoft, GitHub)
Passwordless authentication using WebAuthn, replacing passwords with cryptographic key pairs stored on your device.
Key Features:
- Built on FIDO2 / WebAuthn standards
- Synced across devices via platform providers
- Eliminates password reuse and phishing risk
- Supported by Apple, Google, and Microsoft
Allows users to authenticate once and access multiple applications through SAML or OpenID Connect protocols.
Key Features:
- SAML 2.0 for enterprise identity federation
- OpenID Connect (OIDC) built on OAuth 2.0
- Centralized identity management and auditing
- Reduces password fatigue across applications
Industry-standard authorization framework that lets applications access user resources without exposing credentials.
Key Features:
- Authorization Code flow for server-side apps
- PKCE extension for public clients (SPAs, mobile)
- Scoped access tokens limit permissions
- Refresh tokens for long-lived sessions
Techniques for securely tracking authenticated users across requests using cookies, JWTs, and token rotation.
Key Features:
- HttpOnly, Secure, SameSite cookie flags
- JWT for stateless session tokens
- Token rotation to limit exposure window
- Session invalidation on logout and timeout
