How does Enterprise Console fit in?

• Not required to provide updates to clients

• May be used to manage clients

Documentation

• Sophos enterprise solutions installation advisor• Sophos Anti-Virus Startup Guide• Knowledgebase

– Ignore docs with references to Remote Updates, SAVAdmin

– Look for EM Library v1.2, Enterprise Console 1.0, Clients 4.5 or 5.0

• http://www.oucs.ox.ac.uk/viruses/sophos/antivirus as a starting point

Questions?

EM Library

Installation• Download required network installer from

micros.oucs• Before installation on Domain Controller

– Optionally create domain a/c with admin privileges• http://www.sophos.com/support/knowledgebase/article/

2522.html• Global credentials used to access and update CIDs (Can be

altered for individual CIDS)

• Run installer– Server: es10sfx.exe (unpacks to \sec10)– Workstation: run es10wssfx.exe – if you run setup.exe

from unpacked files it will fail (tells you only server supported!)

Installation

• To install EM Library only– \sec10\Serverinstaller\EMConsole\setup.exe

• Post Installation– Patch MSDE 2000 engine (use MBSA to determine

appropriate patches)– Not required if only installing EM Library (MSDE

installed by Enterprise Console only)– Note EM Library creates share for EM Library

installation files• Default is C:\Program Files\Sophos Enterprise Manager\

console\bin\inst shared as EMLibInstaller

Configuring EM Library

Create Library

• Location for downloaded files from Sophos• Local or remote• Prompts for installation path and library share

name– Defaults are C:\Program Files\Sophos Enterprise

Manager and SophosEM

• Prompts for path and share name for Central Installation Directories– Default C:\Program Files\Sophos Sweep for NT

shared as Interchk

Create Library

Create network account

• Used to update library files• May need to use pre-created domain account on

a domain controller• Unclear whether you need to pre-create account

if installing on member server in a domain– http://www.sophos.com/support/knowledgebase/

article/2522.html

• On standalone server you can choose option to create account

Create Network Account

Select Parent

Select Parent

• Source of files to download to library• Can be Sophos databank or another library

– Will generally be the Sophos databank

• Credentials available from ITSS restricted facilities web page– https://register.oucs.ox.ac.uk:6123/cgi-bin/dia

gonalley/index– Under Sophos EM Library Update Service– Do not divulge these to anyone except ITSS!

Select Parent

Schedule Downloads

Schedule Downloads

• Sets up schedule for downloading from Sophos or parent library

• Generally set up new schedule and accept defaults

• Downloads updates once every hour (random offset)

• Downloads can also be triggered manually via EM Library

Schedule Downloads

Select Packages

Select Packages

• Default view shows only the current versions of the new Sophos clients

Select Packages

• Uncheck options to see more packages

Download Packages

Download packages

• Triggers initial download of packages to populate both library and central installation folders (CIDs)– Default CID already set up for each package

• If you want to move CIDs (e.g. to linux box) you can do this before downloading– …or later

Download Packages

• Can also be used at any time to trigger manual update of packages

Configuring Packages

Configuring Packages

• Subscribed– Will be downloaded according to schedule

• Unsubscribed– Will not be downloaded– Right-click to subscribe

• Published– Available to child libraries– Right-click to publish

Configuring Central Installations

Configuring Existing CIDs

• Can alter location of CID (e.g. to a different server)

• Can alter credentials to access CID• Can change updating schedule (default is

to update immediately after library is updated)

• Can locate CIDs on other servers, so long as the location is accessible from Windows box (e.g. via Samba)

Configuring Central Installations• Right-click to configure existing CIDs

Add additional CIDs

• Packages/subscribed and right-click on chosen package

• Configure options as per configuring existing CIDs

CIDs — Additional Information

• Note special requirements for CIDs for the following clients (see manuals)– Mac OS X– Netware– Unix

• We will cover some of these points in more detail in future seminars

• Manually update a CID via right-click/Update CID

CID AnatomyTop Level Purpose

cid\

setup.exe Main setup file

cidsync.upd Used to check synchronisation status

sau\ AutoUpdate files


sauconf.xml Optional file to configure updating policy

rms\ Remote Management System files


savxp\ Sophos Anti-virus files


savconf.xml Optional file to configure A-V policy

CID Anatomy

• cidsync.upd– Clients use this to check synchronisation status– Includes details of all files (including ides)– Binary file, generally updated by EM Library

• rms folder is optional– Remote management components used by Enterprise

Console– Need to tell installer not to use it (default is to install

rms)– More on this in the next seminar…

EM Library — Tools/Options

• Console Options– Display, refresh etc.

• Security– Who can run EM Library– Effectively adds and removes users or groups from

the EMLibrary Users group

• Notifications– Method (Email, Event Log, Network Messaging)– What is notified

EM Library — Scripts

• \\server\SophosEM\bin\EMLexp.exe (C:\Program Files\Sophos Enterprise Manager\Library\bin\EMLexp.exe)– Export library settings to XML file– Import library settings from XML file– Trigger manual update of a library– NB File may require editing before import to

different server (see http://www.sophos.com/sophos/docs/eng/manuals/eml_men.pdf)

EM Library — Scripts

• Manual update of child library via batch file– http://www.sophos.com/sophos/docs/eng/man

uals/eml_men.pdf)

Questions?

Sophos Enterprise Console

Enterprise Console

• Install using network installers as per EM Library• Manage clients in a controlled environment, e.g.

college or department– Remote installation and updating of Sophos– Status of Sophos on machines– Reporting

• Apply Policies for updating and A-V engine– Apply via Enterprise Console– Or export to files for inclusion in CIDs

Console View

Viewing Computers

• Actions/Find Computers– Relies on Microsoft networking (browse masters etc.)– Windows XP firewall likely to cause problems

• File/Import computers from file– File format (text file)

[]||name1||name2

– Netbios or DNS names– See help for full information (testing shows that you may need to

include OS)

Organising Computers — Groups

• Need at least one group in order to define policies

• Move PCs from Unassigned into groups

Configuring Policies

• Updating and Anti-virus policies

• Policies may be different for each group

• Updating policy has different sections for each OS– At least one section must be configured

• Updating policy must be set before protecting PCs via Enterprise Console

• Use Comply with… to enforce policies

Updating Policy

• Need to specify at least– Primary source (for updates)– Credentials (if required)

• Can specify other items– How often client checks for updates

Updating Policy

Anti-virus policy• E.g. scheduled and on-access scanning

Protect Computers — Prerequisites

• Need access to clients via file share– XP or other personal firewall– May prefer to install from client

• Need account with admin credentials on clients• Need same account credentials to exist on

server (does not need to be admin)– Don’t have to be logged in as this account– Suspect non-domain issue

• Must configure Updating Policy on group before protecting

Protect Computers — Wizard

Enterprise Console and Firewalls

• 3 services on client (see Appendix B)

• Using TCP 8192-8194

• Connections may be initiated by server or clients

• Be wary of firewalls at both ends

• Only applies for management of machines– Scheduled client updates are always initiated

from the client end

Policies

• Can be applied via Enterprise Console

• Can also be applied using files– Sauconf.xml (Updating policy) in sau folder– Savconf.xml (A-V policy) in savxp folder

• Useful for clients not managed by Enterprise Console– Web-based CIDs

Policies

• Export group policies from Enterprise Console using exportconfig.exe– \sec10\tools or \sec10ws\tools

• More detail in next seminar
