All network connections for the... |
| V-39627 | Medium | The test and development infrastructure must use a gateway to separate access to DoD operational networks. | Acting as the first hop into a test and development environment, the gateway can implement proper routing and provide a first layer of defense against attacks and other unintentional compromise or... |
| V-39669 | Medium | Remote access VPNs must prohibit the use of split tunneling on VPN connections. | The VPN software on a host can be configured in either of two modes. It can be set to encrypt all IP traffic originating from that host, and send all of that traffic to the remote IP address of... |
| V-43317 | Medium | The organization must create a policy and procedures document for proper handling and transport of data entering (physically or electronically) the test and development environment. | Without policies and procedures in place, the organization will not have the authority to hold personnel accountable for improperly handling or transporting data into the test and development... |
| V-39440 | Medium | Development systems must be part of a patch management solution. | Major software vendors release security patches and hotfixes to their products when security vulnerabilities are discovered. It is essential that these updates be applied in a timely manner to... |
| V-39441 | Medium | A change management policy must be implemented for application development. | Change management is the formal review process that ensures that all changes made to a system or application receives formal review and approval. Change management reduces impacts from proposed... |
| V-39611 | Medium | The organization must document and gain approval from the Change Control Authority prior to migrating data to DoD operational networks. | Without the approval of the Change Control Authority, data moved from the test and development network into an operational network could pose a risk of containing malicious code or cause other... |
| V-39614 | Medium | Application code must go through a code review prior to deployment into DoD operational networks. | Prior to release of the application receiving an IATO for deployment into a DoD operational network, the application will have a thorough code review. Along with the proper testing, the code... |
| V-39619 | Medium | Access to source code during application development must be restricted to authorized users. | Restricting access to source code and the application to authorized users will limit the risk of source code theft or other potential compromise. |
| V-39672 | Medium | Virtual machines used for application development and testing must not share the same physical host with DoD operational virtual machines. | Attacks on virtual machines from other VMs through denial of service and other attacks potentially stealing sensitive data such as source code used in application development. It is imperative to... |
| V-39344 | Medium | Network infrastructure and systems supporting the test and development environment must be documented within the organizations accreditation package. | Up-to-date documentation is essential in assisting with the management, auditing, and security of the network infrastructure used to support the test and development environment. Network diagrams... |
| V-39439 | Medium | Development systems must have a firewall installed, configured, and enabled. | A firewall provides a line of defense against malicious attacks. To be effective, it must be enabled and properly configured. |
| V-39438 | Medium | Development systems must have HIDS or HIPS installed and configured with up-to-date signatures. | A HIDS or HIPS application is a secondary line of defense behind the antivirus. The application will monitor all ports and the dynamic state of a development system. If the application detects... |
| V-41494 | Medium | Data used for testing and development must be downloaded through a secure connection to an IA-compliant system for vulnerability scanning prior to deployment in the test and development environment. | It is mandatory that data from an untrusted network or website that is to be used in a testing and development environment be downloaded through a secure perimeter. Bringing data directly from an... |
| V-39433 | Medium | Network infrastructure and systems supporting the test and development environment must be registered in a DoD asset management system. | An asset management system is used to send out notifications on vulnerabilities in commercial and military information infrastructures as they are discovered. If the organization's assets are not... |
| V-39345 | Medium | Network infrastructure and systems supporting the test and development environment must follow DoD certification and accreditation procedures before connecting to a DoD operational network or Internet Service Provider. | Prior to connecting to a live operational network, such as the DISN, systems, at minimum, receive an IATO. A system without an IATO does not show adequate effort to meet IA controls and security... |
| V-39436 | Medium | Application development must not occur on DoD operational network segments. | To reduce the risk of compromise of DoD operational networks and data, application and system development needs to be limited to systems within a network segment designated for development only. |
| V-39435 | Medium | The organization must document impersistent connections to the test and development environment with approval by the organizations Authorizing Official. | An impersistent connection is any temporary connection needed to another test and development environment or DoD operational network where testing is not feasible. As any unvetted connection or... |
| V-39434 | Medium | Network infrastructure and systems supporting the test and development environment must be managed from a management network. | It is important to restrict administrative access to the supporting network infrastructure and systems in the test and development environment, as it reduces the risk of data theft or interception... |
| V-39662 | Low | Access control lists between development and testing network segments within a test and development environment must be in a deny-by-default posture. | To prevent malicious or accidental leakage of information between test and development environments, organizations must implement a deny-by-default security posture. All traffic not explicitly... |
| V-39671 | Low | Installation of operating systems on systems and devices in the test and development environment must be logically separated to prohibit access to any operational network. | Systems are most vulnerable to attack during the installation of an operating system because no security controls have been put in place to protect the system. It is very important to block all... |
