LinuxSecurity ☛ IaC Security Scanning: Ensuring Security in the Open-Source Environment
IaC, or infrastructure as code, is essential to most cloud-based applications. Implementing IaC has advantages that significantly increase the service's characteristics and efficiency. However, as well as its enormous value, IaC has certain security drawbacks, like the spreading of simple security issues on all the files or vulnerability to data exposure, which could greatly affect the security of an open-source environment.
[...]
To manage software infrastructure, engineers dedicate a huge amount of time. And with the growth of cloud computing, revising infrastructure components would take too many resources. However, thanks to IaC, organizing IT infrastructure can be less costly, free of human errors, and less time-consuming.
