Application Security
In addition to networks and devices, we also need to ensure the applications are secure. The software we rely on is vulnerable to breaches, putting sensitive data at risk. There are several key features of application security, including the following:

Input validation steps in like a helpful guide, promptly detecting and highlighting such errors in a vivid red, signaling that certain parameters require correction. Once these inaccuracies are rectified, the form will graciously accept and process the submission. But input validation’s role extends far beyond the user interface. Input validation protects against attacks such as SQL injection, buffer overflow, and integer overflow attacks...
