Develop snort IDS and content inspect service
- Initial commit to show potential structure of a sample service - This wil be part of a larger sample application currently dubbed Service Delivery Controller - Docker container needs to be built and employs open-source Linux packages - Service is deployable in Istio service mesh using provided yaml - Control snort daemon and add custom rules with GRPC messaging - Process snort alerts actively and send to redis and upstream service mesh components - Integrates a web server for better HTTP signature detection - Improved build script for CI with variables - Render k8s yaml snort manifest dynamically with command line options - Improve snort_client sample script for runtime modifications including passing args on CLI, error checking - Update nginx proxy interface - Added logging to snort server and alert process Change-Id: Ic56f9fcd9ed21f64b84b85ac8ee280d69af7b7c9 Signed-off-by: Eddie Arrage <eddie.arrage@huawei.com>
