Registration of Clients F. Status Info -------------------------------------------------------------------------------- A. Overall Information 1. About Warden System Warden is a client-server architecture service designed to share detected security events (issues) among CSIRT and CERT teams in a simple and fast way. This package contains the Warden server. 2. Version 2.1 (2012-00-00) 3. Package structure warden-server/ bin/ getClients.pl getStatus.pl getWebStatus.sh registerReceiver.pl registerSender.pl unregisterClients.pl doc/ AUTHORS CHANGELOG INSTALL LICENSE README warden.mysql etc/ package_version warden-apache.conf warden-client.conf warden-server.conf lib/ WardenConf.pm Warden.pm WardenReg.pm WardenStatus.pm Warden/ ApacheDispatch.pm uninstall.sh -------------------------------------------------------------------------------- B. Installation Dependencies 1. Applications: Perl >= 5.10.1 MySQL >= 5.1.63 Apache >= 2.2.14 2. Perl modules: SOAP::Lite >= 0.712 SOAP::Transport::HTTP >= 0.712 DBI >= 1.612 DBD::mysql >= 4.016 Format::Human::Bytes >= 0.05 Sys::Syslog >= 0.27 File::Basename >= 2.77 Net::CIDR::Lite >= 0.21 DateTime >= 0.61 Getopt::Std >= 1.06 Switch >= 2.14 IO::Socket::SSL >= 1.74 MIME::Base64 >= 3.08 Crypt::X509 >= 0.40 -------------------------------------------------------------------------------- C. Installation 1. Check SHA1 checksum of the Warden server package archive. $ sha1sum -c warden-server-2.1.tar.gz.sig 2. Untar it. $ tar xzvf warden-server-2.1.tar.gz 3. Run install.sh. Default destination directory is /opt/warden-server/ For more information about install.sh options run install.sh -h You must be root for running this script. 4. Configuration files You are advised to check configuration file warden-apache.conf, warden-server.conf and warden-client.conf in warden-server/etc/ directory after installation. For more information about post-installation steps see INSTALL file. Although this is the Warden server package it also contains several functions (for administration and maintenance) that are strictly client-side in a way the Warden system handles functions. Therefore you have to check both server and client config files to make sure your installation of the Warden server was successful and complete. SOAP protocol is used for handling communication between server and clients. Therefore, correct URI of Warden server must be set. Authentication of clients and server is performed using client and server SSL certificates. Both clients and server must have valid certificate. Configuration files contain following parameters: a) warden-client.conf: URI - URI Warden server e.g. 'https://warden.server.com:443/Warden' SSL_KEY_FILE - path to a host key file, e.g. '/etc/ssl/private/warden.server.com.key' SSL_CERT_FILE - path to a host certificate file, e.g. '/etc/ssl/certs/warden.server.com.pem' SSL_CA_FILE - path to a CA file e.g. '/etc/ssl/certs/tcs-ca-bundle.pem' b) warden-server.conf The Warden server configuration file contains: BASEDIR - base directory of the Warden server e.g. /opt/warden-server/ FACILITY - syslog facility e.g. local7 DB_NAME - MySQL database name of Warden server e.g. warden DB_USER - MySQL database user of Warden server e.g. warden DB_PASS - MySQL database password of Warden server DB_HOST - MySQL database host e.g. localhost MAX_EVENTS_LIMIT - maximum number of events that can be downloaded from Warden server in a single getNewEvents client function call e.g. 2000000 c) warden-apache.conf The Apache2 configuration file for Warden server SSLEngine on SSLVerifyDepth 3 SSLVerifyClient require SSLOptions +StdEnvVars +ExportCertData SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL SSLCertificateFile <path_to_server_certificate> SSLCertificateKeyFile <path_to_server_certificate_key> SSLCACertificateFile <path_to_CA_certificate> PerlOptions +Parent PerlSwitches -I <path_to_warden_server_libs> <Location /Warden> SetHandler perl-script PerlHandler Warden::ApacheDispatch SSLOptions +StdEnvVars </Location> 5. Usage of install.sh Usage: $ ./install.sh [-d <directory>] [-k <ssl_key_file>] [-c <ssl_cert_file>] [-a <ssl_ca_file>] [-hV]" -d <directory> installation directory (default: /opt) -k <ssl_key_file> SSL certificate key file path -c <ssl_cert_file> SSL certificate file path -a <ssl_ca_file> CA certificate file path -h print this help -V print script version number and exit Example: $ ./install.sh -d /opt -k /etc/ssl/private/server.key -c /etc/ssl/certs/server.pem -a /etc/ssl/certs/bundle.pem 6. Usage of uninstall.sh Usage: $ ./uninstall.sh [-d <directory>] [-hV] -d <directory> uninstallation directory (default: /opt) -h print this help -V print script version number and exit Example: # ./uninstall.sh -d /opt -------------------------------------------------------------------------------- D. Miscellaneous 1. Error Messages Error messages of the server functions are sent via Syslog. Default is local7 facility. 2. Firewall Settings Make sure that the TCP port listed in /etc/apache2/sites-enables/default is allowed on your firewall. 3. Privileges The Warden server runs only under root privileges. 4. Known Issues No issues are known. -------------------------------------------------------------------------------- E. Registration of Clients The Warden server administrator is responsible for registering new clients or removing those already registered. Both registration or unregistration scripts are provided in the Warden server package. Those scripts should be run from localhost (the same machine the Warden server is installed and running on). Members of Warden community who would like to have their client registered must contact the Warden server administrator with the requirement. This is usually done via secured e-mail. Requestor should provide all important data to the Warden server administrator so that the client can be successfully registered. 1. Register Sender New sender clients are registered in Warden system via registerSender.pl. Following attributes must be provided in order to register new client successfully: hostname - hostname of the client, requestor - organization or authorized person who demands new client registration, service - name of the service of a new registered client, description_tags - tags describing the nature of the service, ip_net_client - CIDR the client is only allowed to communicate from. One can run registerSender.pl with -h argument to see a help. 2. Register Receiver New receiver clients are registered in Warden system via registerReceiver.pl. Following attributes must be provided in order to register new client successfully: hostname - hostname of the client, requestor - organization or authorized person who demands new client registration, type - the type of events the client wish to receive or '_any_' for receiving of all types of events, receive_own_events - boolean value describing if events originating from the same CIDR will be sent to the client, ip_net_client - CIDR the client is only allowed to communicate from. One can run registerReceiver.pl with -h argument to see a help. 3. Unregister Client In the Warden system, already registered clients can be removed (unregistered) via unregisterClient.pl. Following attribute must be provided in order to unregister existing client successfully: client_id - ID of the client that should be removed (unregistered). One can run unregisterClient.pl with -h argument to see a help. The process of unregistration deletes this client from clients table in DB. But all messages stored by this client (considering "sender" client) are not deleted, they are merely set 'invalid' in DB table events. -------------------------------------------------------------------------------- F. Status Info Functions in this section show status of the Warden server and active (registered) clients to the Warden system administrator. Similarly to (un)registration, these functions should be run from localhost (e. g. from the same machine the Warden server is installed and running on). 1. Get Status Function getStatus is accessible via getStatus.pl. Function has no input parameters and returns info about the Warden server and its DB status. 2. Get Clients Function getClients is accessible via getClients.pl. Function has no input parameters and returns detailed information about all registered clients. -------------------------------------------------------------------------------- Copyright (C) 2011-2012 Cesnet z.s.p.o
