3.3.5 Logging Protection
If an authorized administrator wants to backup the logs to a syslog server, then protection must be
provided for the syslog server communications. This can be provided in one of two ways:
1. With a syslog server operating as an IPsec peer of the TOE and the records tunneled over
that connection, or
2. With a syslog server is not directly co-located with the TOE, but is adjacent to an IPsec
peer within a trusted facility, and the records are tunneled over the public network.
3.3.5.1 Syslog Server Running on an IPsec Endpoint
For deployments where the syslog server is able to operate as an IPsec peer of the TOE, the IPsec
tunnel will protect events as they are sent to the server. When an audit event is generated, it is
simultaneously sent to both the external server and the local store. Examples of products that can
be installed on a syslog server to allow it to be an IPsec peer include the Racoon tool that is part
of the IPsec Tools on many Linux systems, strongSwan, Openswan, and FreeS/WAN.
Following are sample instructions to configure the TOE to support an IPsec tunnel with aes
encryption, with 10.10.10.101 as the IPsec peer IP on the syslog server, 10.10.10.110 and 30.0.0.1
as the local TOE IPs, and the syslog server running on 40.0.0.1 (a separate interface on the syslog
server).
