With the growing number of cyber security threats, it is essential for everyone to know, mitigate, monitor, and prevent attacks on your apps. I have started this technology series as a small contribution to sharing the knowledge of whatever I have gone through so far. I hope my efforts will be useful to many software engineering aspirants and professionals who wish to use this information in their day-to-day work.

1. What Are the Important Aspects to Consider in Order to Secure Your Applications?

Authentication and authorization ( if your authentication part is compromised, hackers can easily penetrate into a user app and do whatever they want, so it is important to safeguard your authentication mechanism to the app, API, or system.
Logging: Application logs are essential and, more importantly, without which you won’t be able to identify any security incident; application-specific data is used for investigation. You should follow the best practices as much as you can to log the data.
Encryption on data: There are multiple encryption algorithms that I will cover at the end of the video today; it is safe when you encrypt the data while transmitting from sender to receiver. Decryption is done at the receiver level to get the actual data.
