FCSS Public Cloud Security · Build recall with a focused review session.

32 cards. Read the term and the definition here. The deck at the top of this page is optional.

Shared responsibility model
The provider secures the physical and managed-service layers, while the customer secures identity, data, guest configuration, and workload-level controls within the cloud account.
Security of vs in cloud
Security of the cloud covers provider facilities, hardware, and managed-service patching. Security in the cloud covers customer data, access management, encryption choices, and workload configuration.
IaaS responsibility boundary
The customer patches the guest operating system, secures the runtime and applications, and configures network controls, while the provider secures hypervisor and physical infrastructure.
Compliance inheritance limits
Provider audit reports cover only provider infrastructure. Customers must generate their own evidence for workload configuration, access logs, and data handling to satisfy auditors.
Account isolation blast radius
Splitting environments and tiers into separate cloud accounts or subscriptions confines a compromised credential or misconfiguration to one boundary rather than the whole estate.
Cloud audit log enablement
Audit trails such as CloudTrail, Azure Activity Log, and GCP Cloud Audit Logs are often not fully enabled by default and must be turned on per account or project.
VPC peering limitation
Peering connects two networks directly but is non-transitive, so a peered network cannot reach a third network through the peer without additional transit infrastructure.
Stateful versus stateless filtering
Security groups and NSGs track connection state and allow return traffic automatically. NACLs are stateless and require explicit rules for both directions and ephemeral ports.
Longest prefix route match
When multiple routes match a destination, the most specific prefix wins. A /24 route to a firewall overrides a broader /16 route to a gateway.
Hub-and-spoke inspection
Spoke networks route traffic to a central hub firewall, which applies policy and forwards to the destination spoke or to the internet through a NAT gateway.
Asymmetric routing failure
A stateful firewall drops traffic when the return path bypasses it, because the returning packet matches no existing session. Both directions must traverse the same device.
Private endpoint connectivity
PrivateLink, Azure Private Endpoint, and Private Service Connect expose managed services over private addresses, keeping data-plane traffic off the public internet.
Overlapping CIDR conflict
Two networks with identical or overlapping address ranges cannot be peered directly. Resolve with a redesigned address plan or NAT performed by the firewall.
FortiGate VM licensing models
BYOL requires applying a license file tied to the instance. On-demand or pay-as-you-go instances bundle entitlement and register automatically with FortiCare.
NIC to port mapping
FortiGate VM images map cloud network interfaces to firewall ports in a fixed order, typically port1 for management or outside and port2 onward for internal segments.
Cloud HA floating IP
On failover the secondary FortiGate assumes the floating or secondary address, and cloud route tables or load balancer targets must be repointed to the new active unit.
FGCP unicast heartbeat
Cloud instances cannot rely on Layer 2 broadcast, so FortiGate HA uses unicast heartbeat traffic over a dedicated path or cloud-native HA API integration.
Bootstrap configuration injection
Cloud-init or user-data supplies the initial admin password, management route, and FortiManager registration so a new appliance is reachable without console access.
Autoscale cluster orchestration
Elastic FortiGate deployments need external orchestration to license new instances and synchronize policy, since instances are created and destroyed dynamically by cloud APIs.
FortiGate VM sizing drivers
Throughput for IPsec and TLS inspection, plus concurrent and new session rates, determine the required vCPU and memory tier more than the cloud instance family.
CNAPP scope
A converged platform combining cloud security posture management, workload protection, identity entitlement analysis, infrastructure-as-code scanning, and container protection.
CSPM benchmark evaluation
Posture tools compare resource configuration against CIS Foundations Benchmarks and provider best practices, scoring findings by severity and reachable exposure.
CIEM effective permissions
Identity entitlement analysis finds unused permissions, privilege escalation paths, and cross-account trust relationships rather than misconfigured resource settings.
CWPP runtime coverage
Workload protection monitors vulnerability and patch state, malware, file integrity, and process behavior on virtual machines and container workloads.
Infrastructure-as-code scanning
Templates such as Terraform and CloudFormation are evaluated before deployment for public storage, open security groups, missing encryption, and absent logging.
Attack path prioritization
Chaining a public exposure to a privileged identity to a sensitive data store identifies genuinely exploitable risk, reducing alert volume compared with flat finding lists.
Posture drift remediation
Continuous re-evaluation after each deployment detects configuration drift, and event-driven or policy-as-code automation restores the approved baseline automatically.
Gateway load balancer inspection
AWS GWLB and Azure Gateway Load Balancer encapsulate traffic with GENEVE and steer it transparently to FortiGate appliances without changing spoke route tables.
Egress inspection design
Private subnets route default traffic through a FortiGate pair for domain filtering, application control, and TLS inspection before reaching a NAT gateway.
TLS inspection prerequisites
The firewall presents a certificate from a trusted internal CA that endpoints trust. Without distribution, filtering falls back to SNI and category-based controls.
Dynamic address objects
Cloud or SDN connectors populate firewall address objects from instance tags or metadata, so policy follows workloads as they scale or move.
Firewall log correlation
FortiGate traffic and event logs sent to FortiAnalyzer or a SIEM are joined with VPC flow logs and cloud audit logs to reconstruct incident timelines.
