Installation 24 AntiVir WebGate Avira GmbH
Configuration 4 Configuration You can tune AntiVir WebGate for optimal performance. Right after installation, you have the possibility to make the most important adjustments. The most common settings are suggested. You can modify these settings anytime, to adjust WebGate to your requirements.
Configuration 4.1 Overview Configuration files The configuration is defined in two files: z avupdater.conf is used by all AntiVir programs. This file defines basic settings for automatic updates and for generating reports in logfiles or by emails. The file is located in /etc . z avwebgate.conf defines WebGate specific procedures, network configuration, proxy server integration and the program’s reactions when detecting viruses or unwanted programs. The file is located in /etc.
Configuration WebGate without Proxy Server (Network Configuration 0) If there is no proxy server, WebGate stands between Clients and the Internet. It can be installed directly on Clients or on another computer. WebGate directs the Clients’ enquiries to the Internet and scans the answer from the Internet. The access to infected files from a Website is blocked and only not infected files are forwarded to the Client. From the Client’s point of view, WebGate is functioning as a proxy server.
Configuration WebGate between Client and Proxy Server (Network Configuration 1) In this configuration, the other proxy server can be attacked by malicious software. If you want complete protection for your proxy server (normally), network configuration 2 is recommended. See WebGate between Proxy Server and Internet (Network Configuration 2) – Page 29. This configuration is suitable when the proxy is connected to other servers and the Clients need to be protected from infection.
Configuration WebGate forwards the HTTP and FTP inquiries to localhost port 8080. Change the port of the original proxy server according to the value of HTTPProxyPort (in avwebgate.conf ), so that it can contact WebGate. For example: serverport 8080 If WebGate is installed on the actual proxy server: Make sure that WebGate does not respond on the same server port, as is the case in the example above.
Configuration The example assumes the following configuration of the proxy server: host proxy.mycompany.com serverport 3128 So the proxy server responds on port 3128. Make the following settings in avwebgate.conf (example): HTTPPort 8080 Configure the other proxy server, so that it does not directly serve inquiries to the Internet, but directs them to WebGate (e. g. port 8080). This port must correspond to the value of HTTPPort in avwebgate.conf .
Configuration means that the Clients have no direct connection to the FTP servers, but to WebGate. In order for WebGate to make a substitute connection to FTP servers, you need to specify the address and the name of the FTP servers.
Configuration RefreshInterval or – if this is 0 – the value of KeepaliveInterval. Furthermore, WebGate sends "NOOP" commands to the server within the established KeepaliveInterval, so that it also maintains the connection to the server during sending and receiving larger files to or from the Client. 4.4 Integration over ICAP Interface If there is a caching server with ICAP support in the network, WebGate can be integrated with the ICAP interface.
Configuration Scanning Outgoing Data Traffic (Request Modification) The ICAP Client sends an HTTP request to WebGate (ICAP-Server) for scanning. If the data is not infected, it is returned to the ICAP Client and from there it is sent to the destination server. If the request is blocked (i. e. in case of a virus detection), WebGate generates an HTML page, based on the corresponding HTML template, and sends this to the ICAP Client. In this case, the original request is not sent to the server anymore.
Configuration 4.5 Configuration Files This part describes the structure of AntiVir WebGate configuration files. WebGate reads these files by program start. It ignores empty lines and commented lines, beginning with #. The program is provided with default values, which are important for many procedures. Some options can be deactivated with a # at the beginning of the line (commented) or can be set with default values. These can be activated by removing the # character or by changing the values. 4.5.
Configuration WebGate should assume after start (and thus turning in the root permissions). User 65534 Group 65534 WebGate must first start as root. If you do not want this, you must specify the values for User and Group in the file /etc/avwebgate.conf . AllowHTTPS Tunnel Allow HTTPS tunnel: WebGate allows tunneling for SSL connections (HTTPS). As the data is encrypted, it is not scanned. WebGate does not interfere with the transaction, it just forwards the data.
Configuration This method does not work for all Clients. When encountering problems: Use the KeepaliveInterval option. z If none of the above mentioned methods is used, WebGate can send messages to the Client at certain intervals. The value must be smaller than the one set in the Client or proxy server. Default: KeepaliveInterval HTTPProxy... 30 Settings for HTTP proxy server: These settings work only for Network Configuration 1.
Configuration ArchiveMax Recursion Maximum recursion level: When scanning recursive archives, the level of the recursion can be limited. The null value means all archives are completely unpacked, regardless of their recursion level. Default: ArchiveMaxRecursion 20 ArchiveMax Ratio Maximum compression rate for archives: This option limits the scanning to files which do not exceed a certain compression level.
Configuration z 0: EMERGENCY z 1: ALERT z 2: CRITICAL z 3: ERROR z 4: WARNING z 5: NOTICE z 6: INFO z 7: DEBUG For example, LogLevel 4 means that the logfile contains all EMERGENCY, ALERT, CRITICAL, ERROR and WARNING notifications. NOTICE-, INFO- and DEBUGmessages will not be recorded. LogLevel 4 Syslog Facility Syslog facility: WebGate sends notifications to syslog daemon for all important operations. You can specify the facility for these messages.
Configuration Allow Client Addresses Allowing connections for certain Clients/ networks: WebGate can activate certain Clients or networks using this option. Single Clients are set using their IP address. A network is set typing a ’/’ and its netmask (for example, 192.168.1.0/24). AllowClientAddresses 127.0.0.1 192.168.0.0/16 If you do not specify any IP address, the access is not restricted. If you specify at least one IP address, the access is permitted only to the entered IPs. Anyone else has no access.
Configuration Detect... Detection of other types of unwanted programs: Besides viruses, there are some other types of harmful or unwanted software. You can activate their detection using the following options: DetectADSPY yes DetectAPPL yes DetectBDC yes DetectDIAL yes DetectGAME no DetectHEUR-DBLEXT yes DetectJOKE no DetectPCK no DetectPHISH yes DetectSPR no Heuristics Macro Macrovirus Heuristics: Activates the heuristics for macroviruses in documents.
Configuration 4.5.2 Configuration File avupdater.conf This section provides a short description of the settings in avupdater.conf. These settings affect all AntiVir products you have installed on the computer. For this reason we refer to "AntiVir" in general, instead of just "AntiVir WebGate". You can learn how to edit this file easily, in Configuration Script – Page 43. You must restart the Internet Updater, if you modify any values regarding the Internet Updater manually in avupdater.
Configuration z HTTP proxy server z Port z Username and password for the HTTP proxy server if necessary. Example: HTTPProxyServer HTTPProxyPort HTTPProxyUsername HTTPProxyPassword Syslog... proxy.domain.com 8080 username password Syslog settings: WebGate sends messages for all important operations to the syslog daemon. You may specify the facility and priority for these messages. Default is: SyslogFacility user SyslogPriority notice These values apply even if the option is not active. GnuPG...
Configuration The access control scheme is saved in a separate file, specified with the parameter AclConfigFile in /etc/avwebgate.conf Several examples are included in /doc/avwebgate.acl.example. 4.6 Configuration Script You can comfortably setup AntiVir using the configuration script configantivir. This script edits the settings in avupdater.conf, intercepts possible invalid entries and restarts the necessary processes. The procedure using the script is really easy.
Configuration The script reports saving the configuration file. It gives information on the Internet Updater activity and asks if you want to restart the Updater: Would you like to restart the update daemon using the new configuration? [y] Confirm with Y or Enter. The Internet Updater is restarted. Finally, the script displays the summary of the configuration. 4.7 Regular Updates Configuration The performance and effectiveness of antivirus software depend on updating.
Configuration Confirm with Enter all settings, until you reach the proxy server option: If this machine is sitting behind an HTTP proxy server, you will need to configure AntiVir with the appropriate proxy settings. Internet access is required in order to make updates. available options: y n Does this machine use an HTTP proxy server? [n] Type Y. You are then asked for the name of the proxy server: What is the HTTP proxy server name? [] Type its name (example): proxy.domain.
Configuration 4.7.1 Configuring Automatic Updates through Internet Updater The Internet Updater is a very simple daemon, which performs the following commands at fixed intervals: antivir --update Automatic Start of Internet Updater It is important that the Internet Updater starts automatically by every system start. If you have performed the installation as described in Installing AntiVir WebGate – Page 13, your system is correctly set.
Configuration to use a local mirror to check for and fetch updates, which is important when the mirror-script or Internet Update Manager is used. HTTPUpdate Server The Internet Updater can be configured for a local mirror with the HTTPUpdateServer directive in the /etc/avupdater.conf file.
Configuration – 2 for updates every two hours – d for daily updates If you decide for daily updates, you must then set the time: The AntiVir Updater can be set to always check for updates at a particular time of day. This is specified in a HH:MM format (where HH is the hour and MM is the minutes). If you do not have a permanent connection, you may set it to a time when you are usually online. You may also let AntiVir choose a random time (r).
Configuration 4.8 Verifying Updates Authenticity with GnuPG GnuPG is a free alternative to the encryption program PGP (Pretty Good Privacy). Using GnuPG you can verify the authenticity of the AntiVir Updates. It is highly recommended to use GnuPG. However, this procedure requires intensive knowledge of Unix and GnuPG. In case of configuration errors, there is the danger to deactivate AntiVir updates. You can find more details about GnuPG at http://www.gnupg.
Configuration Restart Internet Updater, to activate the new settings in avupdater.conf: /usr/lib/AntiVir/avupdater restart From now on, GnuPG authenticates the Updates. 4.9 Templates Configuration If you have a valid license file, you may customize various notification web pages and emails generated by AvWebGate. WebGate will send these for example, in case of detecting viruses or unwanted programs: alert, blocked, error or progress template.
Configuration Email Templates Template Meaning alert.mail Used when an alert is found by AvWebGate Used when AvWebGate has blocked a suspicious file (using various block-settings in avwebgate.conf) blocked.mail 4.10 Testing AntiVir WebGate After completing the installation and configuration, you can test the functionality of AntiVir WebGate using a test virus. This will not cause any damage, but it will force the security program to react when the computer is scanned.
Configuration 52 AntiVir WebGate Avira GmbH
Operating 5 Operating After concluding installation and configuration and AntiVir WebGate is running, WebGate guarantees continuous monitoring of your system. During operation you might have to make occasional changes in settings, as described in Configuration – Page 25. You can easily manage and configure AntiVir WebGate using the graphical user interface integrated in the program. This Chapter is divided in the following parts: 5.
Operating 5.2 Procedures when Detecting Viruses or Unwanted Programs If correctly configured, AntiVir is set to deal automatically with all the tasks on your computer: z The infected file is repaired or at least deleted. z If it could not be repaired, the access to the file is blocked and, according to the configuration, the file is renamed or moved. This eliminates the risk of infection. You should however follow these guidelines: Try to detect the way the infection "sneaked" on your system.
Graphical User Interface (GUI) 6 Graphical User Interface (GUI) 6.1 Overview The graphical user interface (GUI) assists you in operating, configuring and updating AntiVir WebGate and it graphically displays the monitoring process. AntiVir WebGate is fully functioning and configurable even without GUI. The interface is an independent application, which can start and stop without influencing AntiVir WebGate. You need Java 1.4.0 or higher for using the GUI.
