Security information

Access control Mechanism description (authentication & authorization)

The authentication method is based on trusted digital certificates. Depending on the server configuration and action requested, the users may be required to present VOMS attributes in their proxy certificates.

The L&B version 2.0 server has introduced an authorization mechanism to control the originators of events and allows to make use standard LCAS plugins.

How to block/ban a user

Banning users isn't possible in LB.

Network Usage

By default L&B server listens on port 9000 for incoming queries, 9001 for events, and 9003 for WS interface queries. The glite-lb-logd daemon listens on port 9002.

L&B proxy communicates on two UNIX sockets: /tmp/lb_proxy_server.sock (queries) and /tmp/lb_proxy_store.sock (incoming events).

Firewall configuration

The firewall configuration should allow the access to these ports:

  • 9000/TCP, 9001/TCP and 9003/TCP.
  • 2170/TCP for the resource BDII service.

Security recommendations

None
