TABLE OF CONTENTS 01 Understanding Common Security Threats Strategies to Prevent Security Threats Conclusion Continuous Security Measures 02 04 03 This presentation aims to provide a comprehensive guide to preventing common security threats in web apps, offering strategies and best practices to safeguard digital assets and maintain user trust in the ever-evolving digital landscape.
- 3. SQL Injection Attack Hackers exploit web app flaws by inserting bad code into input fields to break into databases and access or damage sensitive data. These attacks can disrupt data, manipulate information, and compromise business and customer security. Attackers inject harmful scripts into web pages to steal cookies, deface sites, or redirect users to malicious sites, compromising user accounts and important information. Cross-Site Scripting (XSS) Cross-Site Request Forgery (CSRF) Understanding Common Security Threats Trick logged-in users into unintended actions, like changing account info or approving fake transactions, resulting in financial loss or data leakage.
- 4. Exploring other security threats on the horizon. MORE SECURITY THREATS Insecure Direct Object References (IDOR) Flaws allow attackers to access or modify data by manipulating references, potentially exposing important data and causing unauthorized changes. Security Misconfiguration Leaving default passwords or exposing unnecessary services creates security vulnerabilities, providing easy entry points for attackers. Broken Authentication and Session Management Flaws in authentication and session management can lead to unauthorized access to accounts and sensitive information.
- 5. Strategies to Prevent Security Threats 1 Validation and Sanitization Implementing thorough validation and sanitization of user input to defend against SQL injection, XSS, and other code injection attacks. 2 Prepared Statements and Parameterized Queries Always use prepared statements and parameterized queries for database interactions to prevent SQL injection attacks. 3 Content Security Policy (CSP) Implementing a Content Security Policy to block rogue scripts and reduce XSS risks.
- 6. Anti-CSRF Tokens Implementing anti-CSRF tokens to verify legitimate user requests and prevent unauthorized actions. Secure Authentication Mechanisms Secure Session Management Using robust authentication methods such as multi-factor authentication and secure password storage to prevent unauthorized access. Proper session management practices to prevent session hijacking and replay attacks. Best Practices for Safety
- 7. Least Privilege Principle Restricting users, apps, and services to only the permissions required for their role to limit breach impacts. Regular Security Audits and Penetration Testing Conducting security audits and penetration testing to identify and patch security holes. Secure Configuration Management Ensuring secure application and server configurations by disabling unnecessary features, services, and accounts, and using automated tools to scan for misconfigurations. BEST PRACTICES FOR SAFETY - CONTD.
- 8. Keep Software and Dependencies Updated Consistently ensuring that software is kept current and security patches are regularly applied to minimize vulnerabilities and enhance protection. Educate and Train Your Team Ongoing training and knowledge sharing to help developers identify and mitigate new security threats. Continuous Security Measures 1 2
