| Accountability | NS | - | |
| Reliability | Availability | High | Communications with the outside world are even more important than internal processing. Failure of facilities in this Environment will obstruct customer interaction and therefore lead to negative customer experience and damage to the brand. |
| Integrity | Medium | Because facilities in this Environment are used for interaction with external systems and users, sufficient provisions should be taken to safeguard the integrity of these facilities. Because facilities are placed in a safe (physical) location, in most cases the "Medium" level will be adequate. |
