Network and Communication Security 

Your network infrastructure is extremely important in protecting your system. Your network needs to support the communication necessary for your business and your needs without allowing unauthorized access. A well-defined network topology can eliminate many security threats based on software flaws (at both the operating system and application level) or network attacks such as eavesdropping. If users cannot log on to your application or database servers at the operating system or database layer, then there is no way for intruders to compromise the machines and gain access to the backend system’s database or files. Additionally, if users are not able to connect to the server LAN (local area network), they cannot exploit well-known bugs and security holes in network services on the server machines.

The network topology for the Accounting Engine is based on the topology used by the SAP NetWeaver platform. Therefore, the security guidelines and recommendations described in the SAP NetWeaver Security Guide also apply to the Accounting Engine. Details that specifically apply to the Accounting Engine are described in the following topics:

·        Communication Channel Security

This topic describes the communication paths and logs used by the Accounting Engine.

·        Communication Destinations

This topic describes the information needed for the various communication paths, for example, which users are used for which communications.
