Page 22: Application Management
1.2.3 Application Management SNMP Agent The F-Secure SNMP Agent is a Windows NT SNMP extension agent, which is loaded and unloaded with the master agent. The F-Secure SNMP Agent offers a subset of Policy Manager functionality, and it is meant primarily for alert and statistics monitoring.
Page 23: Introduction To F-Secure Policy Manager
“Setting Up Cisco NAC Support”, 253. Introduction to F-Secure Policy Manager This section contains a brief introduction to F-Secure Policy Manager. For more information, see F-Secure Policy Manager Administrator’s Guide. F-Secure Policy Manager provides a scalable way to manage the security of numerous applications on multiple operating systems from one central location.
Page 24: Main Components Of F-Secure Policy Manager
These policies are defined in F-Secure Policy Manager Console and then distributed to the workstations through the F-Secure Policy Manager Server. It can be used to remotely install F-Secure products on other workstations without the need for any intervention by the end user.
Page 25: F-Secure Policy Manager Features
It handles all management functions on the local workstations and provides a common interface for all F-Secure applications, and operates within the policy-based management infrastructure.
Page 26: Basic Terminology
A security policy is a set of well-defined rules that regulate how sensitive information and other resources are managed, protected, and distributed. The management architecture of F-Secure software uses policies that are centrally configured by the administrator for optimum control of security in a corporate environment.
Page 27 Policy domains are groups of hosts or subdomains that have a similar security policy. Policy inheritance Policy inheritance simplifies the defining of a common policy. In F-Secure Policy Manager Console, each policy domain automatically inherits the settings of its parent domain, allowing for easy and efficient management of large networks.

Page 126: Overview
Overview This chapter describes how to plan the managed network and what are the best ways to deploy F-Secure Client Security in different types of environments. F-Secure Policy Manager offers you several ways to deploy F-Secure Client Security in your company:...
Page 127: Logging In
CHAPTER 4 4.2.1 Logging In When you start F-Secure Policy Manager Console, the following dialog box will open. Click Options to expand the dialog box to include more options. Figure 4-1 F-Secure Policy Manager Console Login dialog The dialog box can be used to select defined connections. Each connection has individual preferences, which makes it easier to manage many servers with a single F-Secure Policy Manager Console instance.
Page 128 2. Host connection status controls when hosts are considered disconnected from F-Secure Policy Manager. All hosts that have not contacted F-Secure Policy Manager Server within the defined interval are considered disconnected. The disconnected hosts will have a notification icon in the domain tree and they will appear beside the Disconnected Hosts in the Summary tab.
Page 129 CHAPTER 4 3. Note that it is possible to define an interval that is shorter than one day by simply typing in a floating point number in the setting field. For example, with a value of "0.5" all hosts that have not contacted the server within 12 hours are considered disconnected.
Page 130: Creating The Domain Structure
Creating the Domain Structure If you want to use different security policies for different types of hosts (laptops, desktops, servers), for users in different parts of the organization or users with different levels of computer knowledge, it is a good idea to plan the domain structure based on these criteria.
Page 131 Figure 4-4 An example of a policy domain: country offices as sub-domains A third possibility is to group the hosts into subdomains based on the installed F-Secure Client Security version. You could, for example, group hosts that have F-Secure Client Security 6.x installed into one sub-domain, and hosts that have F-Secure Client Security 7.x installed...
Page 132: Adding Policy Domains And Subdomains
The main methods of adding hosts to your policy domain, depending on your operating system are as follows: Import hosts directly from your Windows domain and install F-Secure Client Security on them remotely. Import hosts through autoregistration after F-Secure Client Security has been installed on them locally.
Page 133: Windows Domains
‘Autodiscover Windows hosts’ from the Installation tab in F-Secure Policy Manager Console. Note that this also installs F-Secure Client Security on the imported hosts. In order to import hosts from a Windows domain, select the target domain, and choose ‘Autodiscover Windows hosts’...
Page 134 Figure 4-5 Import Autoregistered Hosts dialog > Autoregistered Hosts tab The Autoregistration view offers a tabular view to the data which the host sends in the autoregistration message. This includes the possible custom autoregistration properties that were included in the remote installation package during installation (see step 6 in Using the Customized Remote Installation JAR Package...
Page 135 CHAPTER 4 Autoregistration Import Rules Figure 4-6 Import Autoregistered Hosts dialog > Import Rules tab...
Page 136 You can define the import rules for the autoregistered hosts on the Import Rules tab in the Import Autoregistered Hosts window. You can use the following as import criteria in the rules: WINS name, DNS name, Dynamic DNS name, Custom Properties These support * (asterisk) as a wildcard.
Page 137 ). This operation is useful in the following cases: NSERT Learning and testing – You can try out a subset of F-Secure Policy Manager Console features without actually installing any software in addition to F-Secure Policy Manager Console. For example, you can create test domains and hosts, and try out policy inheritance features.
Page 138: F-Secure Push Installations
You need to have administrative rights to push install applications on hosts. Before Installing the Hosts Before you start to install F-Secure Client Security on hosts, you should make sure that there are not conflicting antivirus or firewall applications installed on them.

Page 147: Policy-Based Installation
F-Secure Management Agent installed. F-Secure Policy Manager Console creates an operation-specific installation package, which it stores on the F-Secure Policy Manager Server, and writes an installation task to the base policy files (thus, policy distribution is required to start installations). Both base policy files and the installation package are signed by the management key-pair so that only genuine information is accepted by the hosts.
Page 148 The Installation Editor contains the following information about the products that are installed on your target policy domain or host: Product Name Name of the product, which is either installed on a host or domain, or which can be installed with an available installation package.
Page 149 Installation Editor launches the Installation Wizard, which queries the user for the installation parameters. The Installation Editor then prepares a distribution installation package that is customized for the specific installation operation. The new package is saved on F-Secure Policy Manager Server. Start button is used to start the installation operations selected in the Version to Install field.
Page 150 Because the installation operation uses policy-based triggering, you must distribute new policy files. The policy file will contain an entry that tells the host to fetch the installation package and perform the installation. Note that it may take a considerable length of time to carry out an installation operation.

Page 195: Overview: What Can Internet Shield Be Used For
For detailed explanations of different security levels, see “Global Firewall Security Levels”, 195. 6.1.1 Global Firewall Security Levels The Global Firewall Security levels that exist in the F-Secure Internet Shield are: Network quarantine If the Network Quarantine feature is enabled, this security level will be automatically selected when the network quarantine criteria on the host are met.
Page 196 Block all This security level blocks all network traffic. Mobile This security level allows normal web browsing and file retrievals (HTTP, HTTPS, FTP), as well as e-mail and Usenet news traffic. Encryption programs, such as VPN and SSH are also allowed. Everything else is denied and the denied inbound TCP traffic generates alerts.
Page 197: Security Level Design Principles
CHAPTER 6 In this security level all network traffic, inbound Disabled and outbound, is allowed and no alerts are generated. Local rules cannot be created. 6.1.2 Security Level Design Principles Each security level has a set of pre-configured Firewall Rules. In addition, you can create new rules for all security levels for which the Filtering Mode Normal is displayed in the Firewall Security Levels table.
Page 198: Configuring Internet Shield Security Levels And Rules
Configuring Internet Shield Security Levels and Rules This section explains how you can set and select the security levels based on the users' needs. In the practical configuration examples it is assumed that the managed hosts have been imported into the domain structure that was created in chapter 4, which means that, for example, laptops and desktops are located in their own subdomains.
Page 199: Configuring A Default Security Level For The Managed Hosts
CHAPTER 6 You can verify that the new security level change has become effective by going to the Status tab and selecting the Overall Protection window. If the selected security level cannot be used for some reason, the default security level is used instead. The current default security level can be seen in the Global Security Levels table on the Firewall Security levels page.
Page 200: Adding A New Security Level For A Certain Domain Only
6.2.3 Adding a New Security Level for a Certain Domain Only In this example a new security level with two associated rules is created. The new security level is added only for one subdomain and the hosts are forced to use the new security level. This subdomain contains computers that are used only for Internet browsing, and are not connected to the company LAN.
Page 201 CHAPTER 6 3. Click Add Before to add a rule that allows outbound HTTP traffic as the first one on the list. This opens the Firewall Rule Wizard. 4. In the Rule Type window select Allow as the rule type. 5.

Page 203: Configuring Network Quarantine
CHAPTER 6 Configuring Network Quarantine Network Quarantine is an Internet Shield feature that makes it possible to restrict the network access of hosts that have very old virus definitions and/or that have Real-time Scanning disabled. Their normal access rights are automatically restored once the virus definitions are updated and/or Real-time Scanning is enabled again.
Page 204: Fine-Tuning Network Quarantine
6. Click to save the policy data. 7. Click to distribute the policy. 6.3.3 Fine-Tuning Network Quarantine Network Quarantine is implemented by forcing hosts to the Network Quarantine security level, which has a restricted set of firewall rules. You can add new Allow rules to the firewall rules in the Network Quarantine security level to allow additional network access to hosts in Network Quarantine.
Page 205: Configuring Internet Shield Rule Alerts
CHAPTER 6 Configuring Internet Shield Rule Alerts Internet Shield rule alerts can be used to get notifications if certain types of malware try to access the computers. It is possible to issue an alert every time a rule is hit or when illegal datagrams are received, which makes it easy to see what kind of traffic is going on in your system.
Page 206 Step 3. Specify Affected Hosts Choose whether to apply this rule to all connections or to selected connections only. You can either: Check the Any remote host option to apply the rule to all Internet connections, Check the All hosts on locally connected networks option to apply the rule to all connections form the local network Check the Specified remote hosts option to apply the rule to an IP address, a range of IP addresses or DNS addresses.

Page 299 Authorization The right to perform an action on an object. Also the act of proving this right. Backdoor A malicious application or plug-in that opens up a possibility for a remote user to access the compromised computer. This is very often an application that opens up one or more listening ports and waits for connections from the outside, but there are variations of this.
Page 300 Domain Name A unique name that identifies an Internet site (for example, F-Secure.com) The domain name system (DNS) is the way that Internet domain names are located and translated into Internet Protocol addresses. A domain name is a meaningful and easy-to-remember "handle" for an Internet address.
Page 301 False positive False positive is an alert that wrongly indicates that the related event has happened. In the F-Secure Internet Shield the alert text usually indicates this by using words like "probable" or "possible". This kind of alerts should be eliminated or minimised.
