2018-04-24Fix snort rule with blank content & WR packet in alertEddie Arrage2-12/+20
- Fix bug with addition of content field in rule definition that causes rules with a blank content fields to inhibit snort from starting successfully. - Write more of the packet data for snort alert into Redis - Above includes X-Real-IP, X-Forwarded-For header fields for http traffic from proxy that shows source IP Some packet data is missing in alerts from snort.

2018-04-16Extended snort rule add to allow content fieldEddie Arrage4-11/+36
- Exposed the 'content' field in the GRPC server AddRules method - Allows the 'MALWARE-CNC User-Agent ASafaWeb Scan' signature in the community rules to be copied to local rules - Above ensures more deterministic alerts by snort each time the signature is hit - Added here to support the SDC configuration guide, which details how to add this scan rule via GRPC client script Change-Id: I6945c1e500075444134543bb9eb6003a03f1d5cc Signed-off-by: Eddie Arrage <eddie.arrage@huawei.com>
2018-04-05Merge "Fix Nginx lb in k8s/istio"Stephen Wong5-24/+56
2018-04-04Aligned snort-ids default config for SDC scenarioEddie Arrage3-4/+12
- Modified snort-ids alert process to use k8s DNS name 'proxy-access-control' to align with SDC scenario naming - Added default port 50054 to the manifest yaml template and rendering script for communication with proxy-access-control Change-Id: Ib04ee75e5d8ea9921b16b3b4469bed87b1cd2018 Signed-off-by: Eddie Arrage <eddie.arrage@huawei.com>
2018-04-03Fix Nginx lb in k8s/istioEddie Arrage5-24/+56
- Provide workaround to make nginx lb work properly - nginx_client sample can modify default load balancing from three to two servers at runtime - Ensure port 9180 is used for default deploy for lb and servers - Modify render_yaml to specify deploy_name so that clover-server1, 2, 3 can be used for default lb config - Ensure proxy template is aligned to lb to allow the source IP from originating host to be propagated to final destination - Fix default nginx proxy server_name to 'proxy-access-control' and change default proxy destination to 'http-lb' - Split lb service_type to 'lbv1' and 'lbv2' to provide an example of how to modify the run-time configuration of the load balancer after deployment - modify http-lb-v2 to use clover-server4/5 instead of the defualt clover-server1/2/3 - modify http-lb-v1 to use clover-server1/2 instead of 1/2/3 - Aligned pod IP retrival method with nginx_client.py Change-Id: I73fa60a69c93ae1e82a477ef6283c00f67a21360 Signed-off-by: Eddie Arrage <eddie.arrage@huawei.com>

2018-03-31Develop snort IDS and content inspect serviceEddie Arrage16-0/+1318
- 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>
2018-03-30Added initial nginx servicesEddie Arrage20-0/+1255
- Proxy allows ingress traffic to be sent to another element in service mesh - Mirroring is also in the default configuration - Default configuration is to proxy to a clover-server and mirror to snort-ids - A location_path (URI in HTTP requests) can be reconfigured to restrict proxing; default to '/' - A proxy_path can be reconfigured to specify an alternate destination - A mirror path can be reconfigured to specify where traffic will be spanned - The default server_port (listen port) for the proxy is 9180 but can be reconfigured - The default server_name is http-proxy but can be reconfigured - Reconfiguration is done over GRPC with jinja2 template for nginx - Currently snort ids sends alerts to proxy with stub code in GRPC - Refactored the code to have a nginx base with subservices - Proxy, Load Balancer (lb), and Server can share code - mainly GRPC server - Nginx subservices have separate docker builds - Improved build scripts for CI - Render yaml manifests dynamically - Improve nginx_client for runtime modifications (but not really useful yet) Change-Id: Icbff6890021bcc8a8da4690c9261205d6e1ca43a Signed-off-by: Eddie Arrage <eddie.arrage@huawei.com>
