Writing secure source code is fundamental to prevent potential exploits and attacks that could undermine your software applications. Here’s a short list of best practices to help you write secure code and minimize the risk of security vulnerabilities.

1. 6 secure
coding
practices
you can implement today

2. 1.
Validate input and sanitize data
Check data length and
format
Validate characters set
Escape inputs

3. 2.
Manage authentication
and authorization
Use TLS (transport layer security) client
authentication
Implement authentication error messages
Safely store, control, transmit, and manage your
passwords

4. 3.
Adopt the principle of least privilege
Give only the minimum privileges and permissions
Validate permissions on every request
Create tests to validate permissions before the
release
Review permissions frequently

5. 4.
Make the architecture secure
Use subsystems
Use only secure plugins and libraries
Use a simple and user-friendly design

6. 5.
Create multiple security layers
Configure the security settings of each application
Focus on secure programming and secure runtime
environments
Use authentication checkers
Use strong encryption
Protect your database
Use trusted security certificates

7. 6.
Check your code quality
and follow coding standards
Review your code
Use coding standards
Prevent attacks with threat modeling
