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).
Vulnerabilities
Common web exploits, vulnerability databases, and dependency scanning tools for secure development.
An attack that inserts malicious SQL into application queries, potentially exposing or destroying entire databases.
Key Features:
- Exploits unsanitized user input in queries
- Parameterized queries and prepared statements prevent it
- ORM frameworks provide built-in protection
- Can lead to data theft, deletion, or privilege escalation
Injection of malicious scripts into web pages viewed by other users, enabling session hijacking and data theft.
Key Features:
- Stored XSS persists in the database
- Reflected XSS via crafted URLs
- DOM-based XSS manipulates client-side JavaScript
- Content Security Policy (CSP) headers mitigate risk
Cross-Site Request Forgery tricks authenticated users into submitting unintended requests to a trusted site.
Key Features:
- Exploits browser auto-sending of cookies
- Anti-CSRF tokens validate request origin
- SameSite cookie attribute prevents cross-origin sends
- Double-submit cookie pattern as defense layer
The definitive list of the ten most critical web application security risks, updated periodically by the security community.
Key Features:
- Broken Access Control is the #1 risk
- Covers injection, auth failures, and misconfigurations
- Security misconfiguration and vulnerable components
- Standard reference for security audits and compliance
Public repositories that catalog known security vulnerabilities with unique identifiers for tracking and remediation.
Key Features:
- MITRE CVE provides unique vulnerability IDs
- NVD adds severity scoring (CVSS) to CVEs
- Searchable databases for affected software versions
- Integration with vulnerability scanners and patch tools
Tools that scan project dependencies for known vulnerabilities, catching risks in third-party packages before deployment.
Key Features:
- npm audit scans Node.js dependencies
- Snyk provides continuous monitoring and fixes
- GitHub Dependabot auto-creates update PRs
- Software composition analysis (SCA) for compliance
