COMMUNICATION

Policy Manager Communication

Understanding how communication is working in Policy Manager is one of the key issues • Software distributions => How does the installation reach the host?

• Connection troubleshooting => What component is causing the problem?

Most important components are • Policy Manager Console • Policy Manager Server • Managed Hosts

PMC PMS ?

Host

Page 4

Policy Manager Console

Policy Manager Console is used to • Set up corporate, departmental or individual policies • Deploy and distribute policies, updates and installation files to PMS • Receive alarms and alerts when policies are in danger and when security breaches were attempted but thwarted • Generated reports on configurations, statistics, alerts, etc. for policy domains or individual managed devices • Policy Manager console needs access to both Managed Hosts (Push Installations) and Policy Manager Server

PMC PMS Host

Policy Manager Server

Policy Manager Server hosts • Data repository which includes all policy related information (a.k.a. commdir) • Automatic Update System (virus and spyware updates) • Apache Server which manages the connection requests • Policy Manager Web Reporting module including SQL backend Policy Manager Server has to be accessible by Policy Manager Console and Managed Hosts

PMC PMS Host

Page 6

Managed Host

Provides the platform for different centrally managed applications • Workstation, Server and Gateway applications All managed hosts need access to the Policy Manager Server in order to be able to fetch policies and software packages and send back status information (e.g. alerts)

Information Flow

From the Policy Manager Console to the Policy Manager Server • Settings (in the policy) • Software distributions From Management Agent to the Policy Manager Server • Status information • Alerts Page 8

Information Flow Example

Software Distribution • Policy based installation PMS Host reports • Alerts and status information PMC Host Page 9

Introducing Communication Modules

Policy Manager Server • Apache Server • Handles all connections coming from managed hosts and Policy Manager Console Managed host • F-Secure Management Agent (FSMA) • Handles all policy related connections to the Policy Manager Server • F-Secure Automatic Update Agent (AUA) • Handles all database update related connections to the Policy Manager Server Page 10

F-Secure Management Agent (FSMA)

Local communication module used by managed hosts • Fetches policy data from the server’s data repository (commdir) • Posts alerts and status information to the commdir Interprets and enforces the base policy issued by PMC • Instructs the installation of point applications • Restricts/regulates point application settings Each FSMA has a UID (Unique Identifier) • Differentiates hosts from each other even if IP-address or WINS-name is identical Page 11

Apache Server

F-Secure Policy Manager Server uses a stripped down version of Apache Server which manages the communication request coming from the console and managed hosts Apache Server modules • F-Secure Management Server Host Module (FSMSH) • F-Secure Management Server Admin Module (FSMSA) • F-Secure Web Reporting Module Page 12

Apache Server Modules

• Handles FSMA connection requests • E.g. policy file or software package download • Listens on HTTP (by default port 80) • Handles PMC connection request • E.g. software distribution by administrators • Listens on HTTP (by default port 8080) • Handles Web Reporting connection request • Listens on HTTP (by default port 8081) Host Module (

What are Virus Definitions?

Virus definitions are file signatures used for malware detection and removal Updates include • Virus definitions • Spyware definitions • Virus news updates F-Secure has an automated virus definitions update mechanism, so administrators do not have to update databases manually Page 15

POLICY FILE CONCEPT

F-Secure Policy File Concept

F-Secure policies are a set of well defined rules that regulate how sensitive information and other resources are managed, protected and distributed Policy files are centrally configured by the administrator and distributed to the managed hosts via Policy Manager Server • A Policy is a host oriented file, it is not a product oriented file • It contains configurations/settings for all point applications installed on a host Page 19

Policy Files

BPF (Base Policy File) • Created on the PMC, holds administrators settings for a host • Signed with admin.prv

DPF (Default Policy File) • Used after installation by default until BPF arrives on host IPF (Incremental Policy File) • Created on host, includes local changes and status information, statistics APF (Anonymous Policy File) • Created on PMC, included in an installation package Page 20

Policy Hierarchy

IPF is the primary source of settings • BPF is secondary source of settings, unless a setting is marked ”final”, in which case it is primary • DPF is used if IPF and BPF and APF are missing FSMA IPF BPF DPF AVCS DPF Page 21

Policy Manager Data Integrity

The integrity of the policy domain is secured by an asymmetric key pair Private key (admin.prv) • Private part of the key system • Used for digitally signing policy data (creating the encrypted hash) • Only available to Policy Manager Administrators Public key (admin.pub) • Public part of the key system • Distributed to all managed hosts (publicly available, not kept secure) • Used for hash decryption and signature verification Page 22

SOFTWARE DISTRIBUTION

Installation Types

Remote installation • Push Installation • Auto discover Windows hosts • Push install based on IP-address or WINS name • Policy-based installation Local installation • From CD-ROM • With pre-configured package Page 24

FSMA 1. PMC creates a package 2. PMC pushes the package 3. FSMA and point apllication are installed 4. PMC issues a policy for the new host 5. FSMA fetches the policy

Page 25

Installing Point Applications: Remotely

Push install to Windows Hosts feature is used to push installation to hosts based on their IP address or host name • Works in the same manner as if host was autodiscovered Page 26

Installing Point Applications: Locally

From cd, using login script or through some EMS (SMS, Tivoli etc), followed by the Autoregistartion process • Using a login script: ILaunchr utility and JAR package on a fileserver Page 27

Installing Point Applications: ILaunchr Utility

PMC generates a package, xyz.jar

Copy iLaunchr.exe and the xyz.jar to a shared folder on a file server Edit your login script with new command lines Page 28

Policy Based Installation

Once the Management Agent has been installed, it is possible to do installations based on the policy • Make an installation package and distribute a policy where a workstation is instructed to install the product Page 31
