OWASP Top 10

OWASP Top 10: 2023 Edition

Welcome! Today, we dive into the OWASP Top 10, a critical guide for web application security. These vulnerabilities can compromise user data, lead to financial loss, or disrupt business operations.

A1: Injection

Injection attacks occur when malicious data is inserted into an application, allowing attackers to execute their own code. Examples include SQL injection, command injection, and LDAP injection.

A2: Broken Authentication

Weak authentication mechanisms, such as weak passwords or lack of multi-factor authentication, allow attackers to gain unauthorized access to accounts.

A3: Sensitive Data Exposure

Unprotected sensitive data, such as personal information, financial data, or API keys, can lead to identity theft, fraud, or other security breaches.

A4: XML External Entities (XXE)

XXE attacks exploit vulnerabilities in XML processing to read local files or execute system commands, potentially compromising the server.

A5: Broken Access Control

Improper access control mechanisms allow attackers to access resources or perform actions that they should not be authorized to, leading to unauthorized data access or privilege escalation.

A6: Security Misconfiguration

Default or insecure configurations of web servers, frameworks, or cloud platforms can expose vulnerabilities that attackers can exploit.

A7: Cross-Site Scripting (XSS)

XSS vulnerabilities allow attackers to inject malicious scripts into a website, which can steal user information, redirect users to malicious sites, or deface the website.

A8: Insecure Deserialization

Deserialization vulnerabilities occur when data received from untrusted sources is deserialized without proper validation, allowing attackers to inject malicious objects or execute code.

A9: Using Components with Known Vulnerabilities

Using outdated or vulnerable third-party components, such as libraries or plugins, can introduce security risks into your application.

A10: Insufficient Logging & Monitoring

Lack of adequate logging and monitoring makes it difficult to detect and respond to security incidents promptly.

Next Topic: Content Security Policy (CSP)

Content Security Policy (CSP) is a mechanism to enhance the security of a website by restricting the content that can be loaded from third-party sources, reducing the risk of XSS and other attacks. Follow us for more on this important topic!
