Security configuration

FEJ uses Spring Security for authentication purposes. Security configuration is stored in fej-security.xml file.

In-Memory Authentication

By default, for testing purposes, FEJ container uses simple in-memory authentication with NoOpPasswordEncoder encoder and plain-text credentials.

For other password encoder options please check Spring Security 5.0 DelegatingPasswordEncoder. If you need more complex authentication solution please refer to Spring Security documentation.

<bean id="passwordEncoder"
      class="org.springframework.security.crypto.password.NoOpPasswordEncoder" 
      factory-method="getInstance"/>

<sec:authentication-manager id="authenticationManager">
    <sec:authentication-provider>
        <sec:password-encoder ref="passwordEncoder"/>
        <sec:user-service id="userDetailsService" properties="users.properties"/>
    </sec:authentication-provider>
</sec:authentication-manager>

Users are stored in the external properties file named users.properties. It contains single user test with password test and role ROLE_ADMIN:

$ pwd
/usr/share/fixedgej-1.0.0/conf
$ cat users.properties
test=test,ROLE_ADMIN,enabled

LDAP authentication

FEJ also supports authentication against an LDAP server.

Before getting deep into LDAP authentication, let’s get familiar with some LDAP terms.

TermDescription

Dn

Distinguished name, a unique name which is used to find user in LDAP server e.g. Microsoft Active Directory.

Ou

Organization Unit.

Bind

LDAP Bind is an operation in which LDAP clients sends bindRequest to LDAP user including username and password and if
LDAP server is able to find user and password correct, it allows access to LDAP server.

Search

LDAP search is the operation which is performed to retrieve Dn of user by using some user credentials.

Root

LDAP directory’s top element, like root of a tree.

BaseDn

a branch in LDAP tree which can be used as base for LDAP search operation.

When the LDAP authentication option is activated, the default single user mode is turned off.

FIX Session configuration

FIX Antenna java is used for establishing and managing FIX sessions. But FEJ introduce per-file base configuration for each FIX session. All such configuration files are placed into subdirectories of session directory and should follow s_fix_[SESSION_ID].properties mask (this behaviour can be changed with 'sessionConfigManager' bean into fej-server.xml). Additional each subfolder may have SESSION_GROUP_s_fixDefault.properties configuration file which define common option for all group of FIX sessions.

Main options for FIX session(advanced options for FIX session you can find on FIX Antenna Java configuration page):


Property nameDefault valueDescription

sessionType

acceptor

Session type. If type is not defined then session will be resolved as acceptor. Valid values: acceptor/initiator.

host


The connecting host for initiator session

port


The connecting port for initiator session

senderCompID


Assigned value used to identify firm sending message

senderSubID


Assigned value used to identify specific message originator (desk, trader, etc.)

senderLocationID


Assigned value used to identify specific message originator’s location (i.e. geographic location and/or desk, trader)

targetCompID


Assigned value used to identify receiving firm

targetSubID


Assigned value used to identify specific individual or unit intended to receive message

targetLocationID


Assigned value used to identify specific message destination’s location (i.e. geographic location and/or desk, trader)

fixVersion


Version of the FIX protocol

appVersion



backupHost


Backup host for initiator session

backupPort


Backup port for initiator session

incomingSequenceNumber

0

Incoming sequence number

outgoingSequenceNumber

0

Outgoing sequence number

processedIncomingSequenceNumber

0

Last valid incoming sequence number

heartbeatInterval

30

Heartbeat interval (in seconds)

lastSeqNumResetTimestamp



fixFieldList


User-defined fields for messages. If this list is not empty, Engine adds it to each outgoing message.

outgoingLoginFixFieldList


Additional fields for outgoing Logon message

groups


A comma-separated list of routing groups

username

The assigned value used to identify a username to send in Logon message for initiator session and username to validate with

user name from Logon request for acceptor session. The session will be accepted if the username is not defined.

password
The assigned value used to identify a password to send in Logon message for initiator session and password to validate
with password from logon request for acceptor session. The session will be accepted if the password is not defined
disposeOnDisconnectfalse

Disposes FIX session when another side breaks the connection or in case of disconnect. More details about session statuses can be found in the FIX Antenna java documentation.

note: If the property is set to 'true' then reconnect logic will be suppressed.

Custom FIX dictionaries setup

Custom FIX dictionaries setup in FIXEdge Java product based on FIX Antenna custom FIX dictionaries setup (FIX Antenna Java custom dictionaries), but it is FIXEdge Java configuration specific (FIXEdge Java FIX session configuration).

First place 'customFIXVersions' section first into default 'fixengine.properties' file (in conf dir) to set up custom FIX version info for all FIX sessions.

fixengine.properties
# comma separated list of custom FIX dictionary aliases
customFixVersions=FIX44Custom,FIX50Custom

# pair of 'fixVersion' and 'fileName' for each FIX dictionary alias with pattern:
# customFixVersion.<custom FIX version alias>.fixVersion=<base standard FIX version>
# customFixVersion.<custom FIX version alias>.fileName=<custom FIX dictionary file name>

# example of custom FIX dictionary based on FIX.4.4
customFixVersion.FIX44Custom.fixVersion=FIX.4.4
customFixVersion.FIX44Custom.fileName=classpath:fixdic44-custom.xml

# examples of custom FIX dictionary based on FIX.5.0
customFixVersion.FIX50Custom.fixVersion=FIX.5.0
customFixVersion.FIX50Custom.fileName=classpath:fixdic50-custom.xml

The next step is to set defined dictionary aliases as a session's fixVersion or appVersion in the appropriate FIXEdge Java session configuration file 's_fix_[SESSION_ID].properties':

s_fix_session1.properties
# FIXEdge Java session configuration properties

fixVersion=FIX44Custom
s_fix_session2.properties
# FIXEdge Java session configuration properties

fixVersion=FIX50Custom

Scheduling

Background and business purpose

Exchanges have business hours and there cannot be possible to keep a session up all the time. We should use scheduling in the case when we need to start or stop our session by timetable.

Overview

FEJ supports two modes of managing session - immediately while starting and postponed using cron expression. Managing of the timetable can be defined in schedules.xml that is located in the configuration folder.

Deployment and Maintenance

Configuration

The configuration has the following skillet

<?xml version="1.0" encoding="UTF-8"?>
<schedules xmlns="http://epam.com/fej/schedules">
	<schedule id="...">
        	<task name="..." onLoad="..." timeZone="">
        	    <event cron="..."/>
        	    <properties>
					 <property key="..." value="..."/>
				</properties>
       		</task>
        	<task name="..." >
           		..
        	</task>
	</schedule>
</schedules>


  1. schedule
    1. id - id of schedule. This parameter will be used as the name of a session if properties are not defined. Required. Id of a session is taken from files with its parameters by the regexp - " s_fix_(.*)\.properties". It can be changed in fej-server.xml. parameter sessionNamePattern of sessionConfigManager.
  2. task - there can be many tasks - two (start and stop) for one session where properties block is not defined or many tasks for many sessions but in this case properties block should be defined to specify on which session the task will be applied.
    1. name - name[type] of task
      Valid values: 
          start
          stop 
    2. onLoad - whether a session should start during FEJ initialization. If true, the event block will be ignored.
    3. timeZone - time zone for cron expression. Valid values are below. Required for cron expression.
  3. event - used only when onLoad is not defined or false.
    1. cron - cron expression
  4. property
    1. key - valid value: 
               'sessionName' - used for determining session name. If the properties section is not defined then the id of schedule will be used as a session name.
 Time zone valid values
