avast! Distributed Network Manager (ADNM) represents a suite of powerful tools designed to help network administrators manage the avast! antivirus product line across the whole enterprise.
Its unrivaled flexibility and
scalability makes it an ideal solution for networks of any
size, from simple small-business networks up to large
heterogenous networks spanning multiple continents.
The ADNM system consists of the following components:
avast! Management Server (AMS) SQL Database Administration ConsoleThese three components work together with the avast! antivirus products deployed on individual workstations and servers on the network to provide the best possible protection against malware and to minimize the effort needed to manage and monitor their current status.

How it works
The brain of the whole system is the AMS (avast! Management Server). This is where all the hard work is done.The managed machines connect only to the AMS to download latest policies and to report their status and scan results. The Administration Console also connects directly to the AMS. The AMS is based on a SQL Database – either a dedicated MS SQL Server 2000, if available, or, for small and medium-size networks, on its lightweight version, MSDE 2000, which is part of the ADNM installation package. It is assumed that the AMS machine can connect to the Internet via HTTP protocol.
For larger networks, the AMS is expected to be installed on a dedicated computer. It is also possible to deploy multiple AMS' (each having its own database). These can then be instructed to replicate their databases on a regular basis, and also upload all scanning results to a dedicated AMS on which enterprise-wide reporting can then be carried out. The administrators can choose from two communication models used by the AMS and the clients: PUSH or POP. The POP model is suitable especially for larger networks and for networks with roaming users. Each AMS can scale up to tens of thousands of client computers, provided they are all connected by local area network.
The following sections summarize major ADNM features and benefits.
Hierarchical policy structure
ADNM maintains the list of managed computers in a tree structure. The key to effective management is to design and organize this structure to best suit administration needs. It is often ideal to build the tree so that it reflects the actual geographical and organizational structure of the network. In this way, it is quite easy to assign various administration access rights and policies in a natural way since most organizations' structure can be characterized by a tree with headquarters in the root and branch offices underneath. The tree definition can either be built automatically, or can be imported from an external source (in the form of text file). All security policies in the tree are by default inheritied from parents to children but can be overriden (redefined) according to specific requirements.
Discovery and remote deployment
ADNM supports unattended, remote deployment of the avast! installation packages across the network, even spanning multiple domains. This is especially useful for initial product roll out. ADNM also supports periodic discovery of new machines on the network. These two technologies (discovery and remote deployment) can be combined together, resulting in constant search for new machines and automated, controllable deployment of virus protection software to these machines.
Reporting
One of ADNM’s top features is its reporting capability. ADNM provides a wide range of graphical and tabular reports suitable for both regular management reporting and daily network administration. Reports can either be generated directly to the database and consequently viewed in the Administration Console using the integrated Report Viewer, or can be exported to a variety of formats (including PDF, HTML and DOC) and saved to disk. They can even be automatically sent by e-mail to a designated recipient set – an especially useful feature for periodic management reporting.
As any with other ADNM task type, reporting tasks can be scheduled to run periodically at given intervals (daily, weekly etc).
Alerting
With the help of the avast! Notification Manager, the ADNM allows the network administrators to set up very powerful alerting systems. A number of notification objects are supported, such as sending of e-mail messages using SMTP or MAPI (MS Outlook), notification using the Windows popup mechanism (network message), printing the message on a network printer, SNMP traps, or even sending IM messages using MSN/Windows Messenger.
Automatic updates
Fast, automatic updates are one of the key points of effective virus protection. With avast, the updates are incremental, and only new data is downloaded, thus dramatically reducing the transfer time and bandwidth requirements. Typical size of a virus database update is approximately 20-80kb, a program update usually doesn’t exceed approx. 200-500kb. ADNM supports deployment of one or more "mirror servers" – local networked machines that act as storage for the update data and that are automatically synchronized with our system of online Internet servers. The individual nodes on the network then download the data from the mirrors. There can be any number of mirrors and these can also be set up to work in a hierarchical (tree) structure. A special feature of avast! is the PUSH updates. In the PUSH scenario, the updates are initiated directly by our servers (without polling); they result in the mirror servers quickly responding and performing the necessary synchronization. The system uses the SMTP/POP3 protocol as transport layer (i.e. classic e-mail). The technology is protected by asymmetric ciphers and is resistant to unauthorized misuse.
Security
The AMS maintains a system of users and user groups, and their access rights. Each object (be it a task, computer, schedule, event, alerting object or anything else) has an access control list, in which it is possible to set up who can access it and who can’t. This allows the main administrators to narrow down the view of local administrators only to the objects they’re responsible for, without risking any unauthorized changes in the policy settings outside their scope. All communication between the AMS and the console is encrypted by the industry-standard SSL protocol to ensure maximum security. The AMS identifies itself to the console by a digital certificate (either an administrator-supplied certificate or an ad hoc self-signed one) to prove its trustworthness. Only after a proper encryption channel is established credential data is transferred over the network.
Support for notebook users
Roaming machines always represent a great challenge for management systems. They belong to no specific LAN (office), they connect to the corporate network more or less randomly, they are in general not directly addressable and their users are often trying to bypass restrictions set up on their machines by system administrators. ADNM was designed from the very beginning with notebook users in mind.
Communication between AMS and the clients is always initiated by the clients (POP system), overcoming the not-addressable issue. As soon as a notebook connects to the corporate network, no matter in which branch office (or even if it’s via VPN over the Internet), new policies and updates are automatically downloaded and applied, before the potentialy unsafe machine can cause any harm. If the corporate network is unavailable but it’s still possible to access the Internet, the updates are grabbed directly from our Internet servers.
