# SGX Security Although Intel SGX technology claims to deliver various security promises, which we have gone through in previous sections, it is still vulnerable to certain types of attacks. Recent academic researches have discovered several such vulnerabilities and prove that Intel SGX is **not as secure as we thought**. In this section, [Prof. Taesoo Kim](https://taesoo.kim/) explains known security concerns, including cache/branch side-channel attacks and memory safety issues, and corresponding defenses with various working demos. ## SGX Security Issues (presented by Taesoo Kim) {% embed url="" %} Slides are available here: {% file src="/files/-LhmVcxBf2zBzuBoSYEE" %} Slides here {% endfile %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
