The Mission Owner's internet-facing applications must be configured to traverse the Cloud Access Point (CAP) and Virtual Datacenter Security Stack (VDSS) prior to communicating with the internet.
High Severity
<VulnDiscussion>The CAP and VDSS architectures mitigate potential damages to the Defense Information Systems Network (DISN) and provide the ability to detect and prevent an attack before it reaches the DISN. All traffic bound for the internet will traverse the BCAP/ICAP and IAP. Mission applications may be internet facing; internet-facing applications can be unrestricted or restricted (requiring CAC authentication). DOD users on the internet may first connect to their assigned DISN Virtual Private Network (VPN) before accessing Mission Owner enclave or private applications.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

<GroupDescription></GroupDescription>
The Mission Owner of the Infrastructure as a Service (IaaS)/Platform as a Service (PaaS) must configure scanning using an Assured Compliance Assessment Solution (ACAS) server or solution that meets DOD scanning and reporting requirements.
Medium Severity
<VulnDiscussion>Without the use of automated mechanisms to scan for security flaws on a continuous and/or periodic basis, the operating system or other system components may remain vulnerable to the exploits presented by undetected software flaws. Implement scanning using an ACAS server in accordance with USCYBERCOM TASKORD 13-670. - Use an ACAS Security Center server within NIPRNet or within an associated common virtual services environment in the same cloud service offering (CSO). - Implement a secure (encrypted) connection or path between the ACAS server and its assigned ACAS Security Center. Impact Level 2: Applies to IaaS/PaaS CSOs where the Mission Owner has control over the environment. In this case, Mission Owners must provide their own enclave boundary protections or leverage an enterprise-level application protection service instantiated within the same CSO.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

<GroupDescription></GroupDescription>
The Infrastructure as a Service (IaaS)/Platform as a Service (PaaS) must be configured to maintain separation of all management and data traffic.
Medium Severity
<VulnDiscussion>The Virtual Datacenter Management system provides a management plane for privileged access and communications. Separation of management and user traffic, including access to the customer service portal, is provided to the DOD Mission Owner by the cloud service provider (CSP) to provision and configure cloud service offerings. Additionally, service endpoints for application program interfaces (APIs) and command line interfaces (CLIs) are available as part of the Customer Portal network. These systems can be accessed through the internet by DOD privileged users only (e.g., DOD system and network administrators).</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
SRG-NET-000383

<GroupDescription></GroupDescription>
For Infrastructure as a Service (IaaS)/Platform as a Service (PaaS), the Mission Owner must configure an intrusion detection and prevention system (IDPS) to protect DOD virtual machines (VMs), services, and applications.
High Severity
<VulnDiscussion>Network environments and applications installed using an IaaS/PaaS cloud service offering where the Mission Owner has control over the environment must comply with DOD network infrastructure and host policies. Putting an application in the cloud does not take care of all security responsibilities. Without coordinated reporting between cloud service environments used for the DOD mission, it is not possible to identify the true scale and possible target of an attack. An IDPS protects Mission Owner enclaves and applications hosted in an off-premise cloud service offering and may be deployed within the cloud service environment, cloud access point, or supporting Core Data Center (CDC). Additionally, an IDPS facilitates the reporting of incidents and aids in the coordination of response actions between all stakeholders of the cloud service offering and/or mission owner applications. The Mission Owner and/or their cybersecurity service provider (CSSP) must be able to monitor the virtual network boundary. For dedicated infrastructure with a DODIN connection (Levels 4–6), implement an IDPS that monitors and works with the virtual security infrastructure (e.g., firewall, routing tables, web application firewall, etc.) to protect traffic flow inbound and outbound to/from the virtual network to the DODIN connection.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

<GroupDescription></GroupDescription>
The Mission Owner of the Infrastructure as a Service (IaaS) or Platform as a Service (PaaS) must continuously monitor and protect inbound communications from external systems, other IaaS within the same cloud service environment, or collocated mission applications for unusual or unauthorized activities or conditions.
Medium Severity
<VulnDiscussion>Evidence of malicious code is used to identify potentially compromised information systems or information system components. Unusual/unauthorized activities or conditions related to information system inbound communications traffic include, for example, internal traffic that indicates the presence of malicious code within organizational information systems or propagating among system components, the unauthorized exporting of information, or signaling to external information systems. Anomalies within organizational information systems include, for example, large file transfers, long-time persistent connections, unusual protocols and ports in use, and attempted communications with suspected malicious external addresses. This function may be deployed within the cloud service environment cloud access point or supporting Core Data Center (CDC).</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
