Cross-Site Request Forgery - CSRF

Cross-Site Request Forgery (CSRF) is a type of cyberattack where an attacker secretly performs actions on a web page in the name of an authenticated user. This is achieved by tricking the user's browser into sending unintended requests to another website or web application where the user is already logged in. The goal of a CSRF attack is to execute actions within the context of the authenticated user without the user's intent.

Here's a typical process in a CSRF attack:

  1. The attacker creates a fake website or a malicious link that triggers an action on the target website.

  2. The user who is lured into the fake website or clicks on the malicious link is already logged into the target website.

  3. The fake website or the malicious link sends a request to the target website to perform an unwanted action on behalf of the user. This could include changing the password, initiating money transfers, or posting content on social media.

  4. Since the request is received by the target website as an authenticated user, the website executes the request without realizing it's an attack.

CSRF attacks are particularly dangerous when the target website allows confidential or sensitive actions without requiring additional user authentication steps or confirmations. To protect against CSRF attacks, website developers can implement measures like CSRF token checks, where each request is verified to include a valid CSRF token. Users can also protect themselves by logging out when leaving a website and ensuring they don't open untrusted links or websites. Modern web browsers also have built-in safeguards against CSRF attacks.

 


Object-Relational Mapper - ORM

A Object-Relational Mapper (ORM) is a programming pattern and technique in software development that aims to facilitate the connection between object-oriented programming and relational databases. It allows developers to handle database data in the form of object-oriented data types, simplifying data interaction with databases in applications.

Here are some key concepts and functions of an ORM:

  1. Object-Oriented Representation: With an ORM, database tables are mapped to object-oriented classes or models. Each table corresponds to a class, and each row in the table becomes an instance of that class.

  2. Mapping Relationships: ORM enables the representation of relationships between tables in the form of object relationships. For example, in a relational database, two tables may be linked, and these relationships are reflected in object-oriented models.

  3. Data Access and Manipulation: With an ORM, developers can retrieve data from the database, write to the database, and create database queries in an object-oriented way, without the need to write raw SQL queries.

  4. Portability: A good ORM system is typically database-agnostic, meaning you can easily migrate your application from one database to another without changing the application code.

  5. SQL Abstraction: ORM tools abstract the underlying SQL syntax, making programming easier and securing the application against SQL injection attacks.

  6. Consistency and Maintainability: ORM facilitates the maintenance and updating of database tables and schemas, as changes to the database structure are reflected in the ORM models.

  7. Performance Optimization: Advanced ORM systems offer features for optimizing database queries to make them efficient and enhance application performance.

A well-known example of an ORM framework in the PHP world is Eloquent in Laravel, while Hibernate is a popular ORM framework for Java applications.

ORM is particularly useful in applications dealing with complex databases and needing portability across different programming languages and database systems. It abstracts the database layer, allowing developers to focus on application logic rather than worrying about the details of database communication.
