Golang Warsaw #56 Jakub Wołynko Secure access to EC2 (for developers) Agenda – introduction – EC2 in native environment – 3-tier architecture intro – alternative methods of resource connection: groups or equivalent 3-tier architecture3-tier architecture - props and cons – full control over resource access – possibilities of disconnection resources from the internet – in general, more secure – architecture getting more complex – additional costs like VPN, NatGateway – regular resource access become more annoying solution one - bastion host Host Instance ProxyJump Bastion PreferredAuthentications

The goal of the assessment was to identify security issues related to the Istio code base and outbound access of Istio services. • Istio Envoy Usage: The configuration and implemen- tation of Envoy within Istio (NOTE: Envoy itself was not part of the assessment). • Istio Control Plane: Istio Istio operator, side car injector, and other Istio control plane services • Istio Documentation: The documentation and secu- rity guides hosted on istio.io. NCC Group started the assessment with an overall
