In today's digital age, security is a major concern for individuals and organizations alike, with the increasing number of cyberattacks and data breaches making it crucial for developers to have a thorough understanding of security best practices. The growth and speed of cloud-native development have resulted in an expanding attack surface filled with vulnerabilities that can directly impact the safety and privacy of users' data if left unchecked. To raise the bar on security skill sets, developers can use the capabilities of the New Relic observability platform to detect and remediate issues in applications like Juice Shop, a deliberately insecure web application from OWASP. Application monitoring for identifying vulnerabilities in real-time can be achieved through APM, which provides real-time insights into performance and behavior, including response times, error rates, and transaction traces. High error rates can indicate security vulnerabilities or potential threats, such as hack bots trying to find open paths into an application. Error tracking is also crucial, allowing developers to quickly identify and resolve issues that could be exploited by adversaries. New Relic's Vulnerability Management capability helps overcome security blindspots within applications, identifying the most urgent vulnerabilities, calculating the vulnerability surface area, triaging and assigning vulnerabilities, and providing remediation steps. Synthetic monitoring can simulate user behavior and test the performance of applications, identifying potential security issues and vulnerabilities, such as testing access to sensitive information without proper authentication.
