Cross-region anti-virus control for large enterprises

Large enterprise groups usually have many subsidiaries, departments, and branches outside China. The establishment of the network provides a convenient information platform for their operation and management. However, in the face of increasingly rampant virus threats, the enterprise network shows security vulnerabilities everywhere-network congestion, data damage, and confidential leakage. Large enterprise networks require effective anti-virus control and network-wide protection. However, in the face of many cross-regional computer network systems, how to achieve anti-virus management control at a low cost, while also achieving unified deployment and Real-Time Effectiveness of network anti-virus security policies, this is a difficult problem for network managers of every enterprise. Therefore, we propose a cross-region anti-virus control policy.

Anti-Virus cross-region control:

1. What kind of architecture is suitable for cross-region anti-virus control?

At present, large Enterprise networks generally include Enterprise WAN and Enterprise LAN. Enterprise headquarters connect to the LAN of each branch through WAN. For this cross-region network, the B/S anti-virus system has strong adaptability and flexible control. First, because it provides the most realistic Open Foundation for the connection, networking, and unified services of heterogeneous machines and networks, it can well adapt to the complex cross-region characteristics of enterprise networks, this advantage is more obvious for enterprise wide area networks connected by the internet. Second, because the console is based on web interfaces, administrators do not have to perform operations on specific management nodes (such as hosts in the network center data center), and flexible control can be achieved through console mobility.

2. What management mechanism is more effective?

Anti-Virus cross-region control puts forward higher requirements on the management mechanism. Management reliability should be put in the first place because it cannot be confirmed on site. In this regard, the management system should be able to timely feedback the remote network security status and command implementation results, that is, through the active collection and feedback confirmation to ensure reliability. Second, central nodes must be centrally controlled. Remote control is essentially an aspect of enterprise-wide anti-virus. With a central control node, it can achieve unified control over cross-regional branches for anti-virus work, so that network administrators can grasp the overall situation. At the same time, it is necessary to add lower-level management nodes in each controlled subnet to implement local management through authorization, providing flexibility.

3. configure anti-virus policies

In cross-region anti-virus control, policy configuration requirements can be summarized as "Centralized formulation, targeted configuration, and Real-Time Effectiveness ". For networks of different regions, you can set up a dedicated system center with multiple groups. The establishment of the system center allows for unified policy formulation and targeted policy deployment through "group" subdivision. The configuration of the anti-virus policy must take effect in real time to immediately update the protection measures.

4. How to upgrade the cross-region anti-virus system?

The anti-virus system must be upgraded and updated in a timely manner. The following aspects should be taken into account during cross-region upgrade control: internet bandwidth restrictions, upgrade efficiency, and reliability. The solution is to create an independent upgrade server in the branch network, and the upgrade server downloads the update program over the internet. This is equivalent to a single-exit upgrade of the network in the form of a proxy, reducing bandwidth usage. Another advantage of this is that the upgrade is controllable. The Administrator only needs to properly deploy and upgrade the server to control the route of the upgrade data stream, and the load is also balanced.
