Envoy sidecar that is attached to workloads but there are a multitude of ways for a workload to bypass this proxy. This is in some ways by design but the overall security expectations around what Istio can boundaries of the original design.) For example, a workload can bypass the Istio sidecar the following ways: • Non-TCP egress bypass: Istio does not handle UDP packets at all and if an administrator expected from accept(2), both of which can be used to coordinate data transfer. Because of the variety of ways to bypass Envoy, any network restrictions that Istio purports cannot be relied upon as a security

There are a number of ways an attacker would seek to exceed their trust boundaries including authentication bypass, reading sensitive st-practices/security/. The guide iterates over known threat vectors in Istio and provides direct ways to mitigate these. 16 Istio Security Audit, 2023 Issues found In total, the audit found 11 security
