Secure Coding Practices Questions
Common vulnerabilities in software development include:
1. Injection attacks: These occur when untrusted data is sent to an interpreter as part of a command or query, leading to unintended execution of malicious code.
2. Cross-Site Scripting (XSS): This vulnerability allows attackers to inject malicious scripts into web pages viewed by other users, potentially compromising their accounts or stealing sensitive information.
3. Cross-Site Request Forgery (CSRF): In this vulnerability, attackers trick users into performing unintended actions on a website without their knowledge or consent, often leading to unauthorized changes or data theft.
4. Insecure Direct Object References: This vulnerability arises when developers expose internal implementation details, such as database keys or file paths, allowing attackers to manipulate or access unauthorized resources.
5. Security misconfigurations: These vulnerabilities occur when software is not properly configured, leaving it open to attacks. Examples include default or weak passwords, unnecessary services or ports being open, or outdated software versions.
6. Broken authentication and session management: Weaknesses in authentication mechanisms, such as improper storage of passwords or session tokens, can allow attackers to impersonate legitimate users and gain unauthorized access.
7. Insecure cryptographic implementations: Flaws in the way encryption algorithms or protocols are implemented can lead to data leaks or unauthorized access to sensitive information.
8. Unvalidated input: Failing to properly validate and sanitize user input can lead to various vulnerabilities, including buffer overflows, command injection, or SQL injection.
9. Denial of Service (DoS) attacks: These vulnerabilities involve overwhelming a system or network with excessive requests, causing it to become unresponsive or crash, denying service to legitimate users.
10. Insecure deserialization: When untrusted data is deserialized without proper validation, it can lead to remote code execution or other security issues.
It is important for developers to be aware of these vulnerabilities and follow secure coding practices to mitigate the risks associated with them.
