Types of Security attacks on a web app

Web applications are susceptible to a variety of security attacks, which can compromise the integrity, confidentiality, and availability of data and services. Understanding these attacks is crucial for developing robust security measures. Here are some common types of web application security attacks:

1. SQL Injection (SQLi)

• Description: Attackers insert or manipulate SQL queries in web input forms to execute arbitrary SQL code on the database.
• Impact: Unauthorized data access, data modification or deletion, and administrative operations.
• Prevention: Use prepared statements and parameterized queries, validate and sanitize user inputs.

2. Cross-Site Scripting (XSS)

• Description: Attackers inject malicious scripts into web pages viewed by other users. These scripts can run in the context of the user's browser.
• Impact: Data theft, session hijacking, defacement of websites, and distribution of malware.
• Prevention: Validate and sanitize inputs, use Content Security Policy (CSP), and encode output data.

3. Cross-Site Request Forgery (CSRF)

• Description: Attackers trick users into executing unwanted actions on a web application where they are authenticated.
• Impact: Unauthorized actions such as changing account details, transferring funds, or altering application settings.
• Prevention: Use anti-CSRF tokens, validate the origin of requests, and require re-authentication for sensitive actions.

4. Insecure Direct Object References (IDOR)

• Description: Attackers manipulate references to internal objects (like database records) to access unauthorized data.
• Impact: Unauthorized access to sensitive data and functionalities.
• Prevention: Implement proper access controls and validate user permissions.

5. Remote Code Execution (RCE)

• Description: Attackers exploit vulnerabilities to execute arbitrary code on the server.
• Impact: Full control over the web server, data breaches, and further exploitation of the internal network.
• Prevention: Regularly update and patch software, validate and sanitize inputs, and use web application firewalls.

6. File Inclusion Attacks

• Description: Attackers exploit vulnerabilities to include and execute unauthorized files on the server.
• Impact: Remote code execution, data theft, and server compromise.
• Prevention: Validate and sanitize file inputs, use whitelisting for allowed file paths, and configure server settings to disable file inclusion features.

7. Directory Traversal

• Description: Attackers manipulate URL paths to access files and directories outside the web root directory.
• Impact: Access to sensitive files and system configurations, data leakage.
• Prevention: Validate and sanitize URL inputs, use secure coding practices, and restrict file permissions.

8. Session Hijacking

• Description: Attackers steal or predict a valid session token to impersonate a legitimate user.
• Impact: Unauthorized access to user accounts and sensitive data.
• Prevention: Use secure session management practices, encrypt session tokens, and implement HTTPOnly and Secure cookie flags.

9. Man-in-the-Middle (MitM) Attacks

• Description: Attackers intercept and potentially alter the communication between two parties.
• Impact: Data theft, manipulation of transmitted data, and session hijacking.
• Prevention: Use HTTPS/TLS for encrypted communication, employ certificate pinning, and use strong authentication mechanisms.

10. Distributed Denial of Service (DDoS)

• Description: Attackers overwhelm a web application with a flood of requests, causing it to become slow or unavailable.
• Impact: Service downtime, loss of revenue, and degraded user experience.
• Prevention: Implement DDoS protection services, use load balancing, and rate limiting.

11. Broken Authentication and Session Management

• Description: Weak authentication mechanisms and session management practices allow attackers to compromise user identities.
• Impact: Unauthorized access to user accounts and sensitive data.
• Prevention: Use multi-factor authentication, secure session handling practices, and enforce strong password policies.

12. Security Misconfiguration

• Description: Insecure configurations of web servers, databases, and application frameworks.
• Impact: Exposure of sensitive data, unauthorized access, and exploitation of vulnerabilities.
• Prevention: Regularly update and patch systems, follow secure configuration guidelines, and audit security settings.

13. Using Components with Known Vulnerabilities

• Description: Use of libraries, frameworks, or other software components that have known security vulnerabilities.
• Impact: Potential exploitation of these vulnerabilities to compromise the application.
• Prevention: Regularly update and patch components, use dependency-checking tools, and follow security advisories.

14. Insufficient Logging and Monitoring

• Description: Failure to adequately log security-relevant information and monitor for signs of attacks.
• Impact: Delayed detection of security breaches and difficulty in forensic analysis.
• Prevention: Implement comprehensive logging and monitoring, use automated alerting systems, and regularly review logs.
