What is Website Development

Web development refers to the creating, building, and maintaining of websites or web-based applications. It includes aspects such as back-end development, web publishing, web programming, and database management.

Typically, from a non-technical perspective, the term website development has become a catch-all term that includes all aspects of web design or web-based application design, however that is not entirely accurate. Many web developers specialize in a certain area of the development process (backend or frontend) and may not specialize in other areas of the development process even though they technically familiar with it.

• Malicious script is permanently stored on the target server and served to users who access the affected page.
• Reflected (Non-Persistent) XSS:
• Malicious script is embedded in a URL and only served to users who click on a manipulated link.
• Prevention Measures:
• Input Validation:
• Validate and sanitize user inputs to ensure that they do not contain executable scripts.
• Output Encoding:
• Encode user-generated content before rendering it in web pages.
• Content Security Policy (CSP):
• Defines policies to mitigate XSS risks by controlling which resources are allowed to be loaded.

Cross-Site Request Forgery (CSRF):

• Definition: A security vulnerability where an attacker tricks a victim's browser into making an unintended HTTP request on a trusted site where the victim is authenticated. This can lead to actions being performed on behalf of the victim without their consent.
• Prevention Measures:
• Anti-CSRF Tokens:
• Include unique tokens in forms or requests, validating that the request was intentional.
• SameSite Cookie Attribute:
• Restricts when cookies are sent to the server, preventing CSRF attacks.

• Theft of sensitive information, session hijacking, defacement of websites.
• CSRF Impact:
• Actions performed on behalf of the victim, such as changing passwords, making financial transactions.
• User Interaction:
• XSS:
• Requires the victim to visit a page containing the malicious script.
• CSRF:
• Exploits the fact that the victim is authenticated in the target site and doesn't require direct interaction.

Authentication and Authorization

Authentication and authorization are integral components of web security. Authentication verifies user identity, while authorization ensures that authenticated users have the appropriate permissions to access resources. Implementing secure practices in both processes is essential for maintaining a robust and reliable security posture.

• Definition: The process of verifying the identity of a user, system, or application to ensure that they are who they claim to be.
• Key Concepts:
• User Credentials:
• Username/password, biometrics, or other authentication factors.
• Multi-Factor Authentication (MFA):
• Requires users to provide multiple forms of identification for added security.
• Single Sign-On (SSO):
• Allows users to access multiple systems with a single set of credentials.
• OAuth and OpenID Connect:
• Protocols for delegated authentication and authorization.
• Authentication Methods:
• Token-Based Authentication:
• Uses tokens (e.g., JSON Web Tokens) for secure and stateless authentication.
• Session-Based Authentication:
• Relies on session identifiers stored on the server or in cookies.
• Implementation Best Practices:
• Secure Password Storage:
• Hashing and salting passwords to protect against data breaches.
• Password Policies:
• Enforces strong password requirements for users.
• Biometric Authentication:
• Utilizes unique physical or behavioral characteristics for identification.
• OAuth for Third-Party Authentication:
• Allows users to log in using accounts from other services (e.g., Google, Facebook).

Authorization:

• Definition: The process of determining whether an authenticated user has the necessary permissions to access a specific resource or perform a certain action.
• Key Concepts:
• Roles and Permissions:
• Assigns users to roles, each with specific permissions.
• Role-Based Access Control (RBAC):
• Manages access based on predefined roles.
• Attribute-Based Access Control (ABAC):
• Access decisions based on attributes of the user, environment, and resource.
• Implementation Best Practices:
• Least Privilege Principle:
• Grants users the minimum level of access required to perform their job functions.
• Access Control Lists (ACL):
• Lists of permissions attached to an object that specify which users or system processes are granted access.
• Centralized Authorization:
• Centralizes authorization logic to ensure consistency and manageability.
• Regular Auditing:
• Regularly audits and reviews permissions to identify and correct potential security issues.
• Differences:
• Authentication:
• Verifies the identity of a user.
• Authorization:
• Determines what actions and resources an authenticated user can access.
• Integration:
• Authentication and Authorization:
• Often work together, with authentication preceding authorization.
• Security Implications:
• Authentication Risks:
• Insecure credential storage, weak passwords, and vulnerabilities in authentication protocols.
• Authorization Risks:
• Improperly configured permissions, inadequate access controls, and vulnerabilities in authorization logic.
