Security risks of metadata

- [Instructor] Throughout the course, we've seen a few different ways that information could be leaked accidentally through various kinds of metadata, and consequently, we've seen how we can discover information in metadata that might not have been intended for us to know. Embedded metadata while very useful, can contain sensitive data like geolocation information and custom or internal tags that clients and others shouldn't see.

We've also seen that metadata can be maliciously falsified, or simply be incorrect, and that it shouldn't be trusted on critically. Metadata stored by file systems can also present a risk of information loss or exposure in a variety of ways.
