I've always felt that writing code is an art as a software engineer. It takes patience, creativity, and a considerable amount of skill to design something that works seamlessly. There are, however, both excellent and terrible practices in this art genre, just like in any other. The gap between excellent and bad coding techniques can distinguish between secure and unsafe software.

Security is a primary concern for businesses and individuals in the modern digital world. Security breaches can have disastrous results, and hackers are always looking for new weaknesses to attack. It is our duty as developers to make sure that the software we produce is secure and fault-free. In this post, I'll share with you some of the best practices for secure coding that every developer should know.

• Design securely:
  Secure design serves as the foundation of secure code. This implies that security should be taken into account during the entire development process. Security should be a major focus at all stages of the design process, including the final deployment. At every level of development, keep security requirements, risks, and vulnerabilities in mind.

• Follow the Principle of Least Privilege:
  The principle of least privilege is a security concept that limits user access to only what is essential to accomplish their job tasks. You should make sure that your code adheres to this idea as a developer. The danger of a security breach can be reduced by restricting access to sensitive information and system resources.

• Sanitize User Input:
  The entry point for security flaws like SQL injection and cross-site scripting is primarily user input. It is your responsibility as a developer to make sure that every user input is cleaned up before the application uses it. To stop malicious information from being handled by the application, use input validation and filtering techniques.

• Make use of secure coding libraries:
  In software development, using third-party libraries is a frequent technique. Yet, employing old or insecure libraries can make your application highly attackable. Choose secure code libraries that are frequently updated and have undergone a comprehensive security vulnerability analysis.

• Implement Access Control:
  Access control is a key component of secure coding. It ensures that users only have access to the resources that they need to perform their job functions. Implement role-based access control to ensure that users have access only to the resources that are necessary for their job function.

• Use Encryption:
  Encryption is a powerful tool for securing data. Use encryption to protect sensitive data such as passwords and credit card information. Implement encryption at rest and in transit to ensure that data is protected both while it is stored and while it is being transmitted.

• Perform Regular Security Audits:
  Perform regular security audits to identify vulnerabilities in your code. Use automated tools and manual testing to identify security vulnerabilities in your code. Regular security audits can help you identify vulnerabilities early and take corrective action before a security breach occurs.

In conclusion, secure coding is an essential component of software development. Following the best practices for secure coding can help you create software that is secure and free from vulnerabilities. By starting with secure design, following the principle of least privilege, sanitizing user input, using secure coding libraries, implementing access control, using encryption, and performing regular security audits, you can master secure coding practices and create software that is secure and reliable.
