GCP - Professional Cloud Security Engineer - Part 1

Cloud DLP 1. Data discovery and classification of (sensitive) data in Cloud Storage, BigQuery and Datastore. 2. Supports "streaming API" to support additional data sources and custom workloads Data identification using "built-in" and "custom" infotypes. Also performs automatic classification, masking, tokenization and transformation of sensitive data elements (such as PII data) Data Catalog To find, curate and use metadata to describe data assets in the cloud. Use Data Catalog to search for data assets and tag the assets with metadata. CMEK - Generate and manage encryption keys using Cloud KMS. Helps to rotate encryption keys regularly CSEK - Create and manage your own encryption keys and then provide to Google Cloud. You need your own BYOK solution. Cloud External Key Manager (Cloud EKM) - This lets you achieve a secure hold-your-own-key (HYOK) model for key management.  Cloud KMS - Software-backed encryption keys or FIPS 140-2 Level 3 validated HSM.  Clo

Tejas Jain - GCP Constraints & Random Facts

1.  Google Cloud Interconnect Security Cloud Interconnect does not encrypt the connection between your on-premises network and Google's network. Cloud VPN cannot be used with Dedicated Interconnect For additional security, use application-level encryption or your own VPN 2. While using Cloud CDN, the default time-to-live (TTL) for content caching is 3600 seconds = 60 mins 3. Cloud NAT sends only the translation logs and error logs to Cloud Logging service. 4. GCP Dedicated Interconnect - On Premises network device requirements:     10-Gbps circuits, single mode fiber or 100-Gbps circuits, single mode fiber     IPv4 link local addressing     LACP, even if you are using single circuit     EBGP-4 with multi-hop     802.1Q VLANs 5. While using Cloud VPN, the recommended MTU to be configured on the peer VPN  gateway = 1460 bytes 6. Each instance must have at least one network interface. The maximum number of network instances per instance is 8, depending on the instance's machine

Google Cloud Armor - Restrictions

Google Cloud Armor is Google's Network Security service that provides protection against DDoS and web application based attacks. If you have been thinking about enabling Google Cloud Armor for leveraging its DDoS protection and WAF capabilities, you must know the following restrictions: 1. Cloud Armor cannot be enabled on non-HTTP Load balancers. 2. If your HTTP load balancers have Cloud CDN enabled on them, then you cannot enable Cloud Armor on them.       3. If your HTTP Load Balancer has backend buckets instead of backend services, you cannot enable Cloud Armor. This is evident in the below snapshot, where the only option you get is to enable Armor for "Load Balancer backend service". The above restriction is also mentioned in the official GCP document. Click here :  Cloud Armor Limitations . Summary: You can enable Cloud Armor only on HTTP load balancers which have backend services (not buckets) as the backend resources.
