The significance of deploying firewalls for small and medium enterprises

A recent web site counted seven DDoS attacks in 2016, including "Blizzard DDoS Attacks", "zombie cyber attacks with 25,000 cameras", "anonymous organization-initiated operation Opicarus attacks", " Precision NS1 attacks, "five Russian banks have suffered DDoS attacks", "Mirai botnet attack krebsonsecurity", "half of the U.S. Internet offline events".

With a focus on China, the number of cyber attacks monitored by mainland and Hong Kong companies increased by an average of 969% during 2014-2016. In the face of such a frequent network attack, how can enterprises evaluate and solve the network security hidden trouble?

Installing a firewall is a key solution to the strategy, "firewall"--as the name implies is a wall of software and hardware installed in the external network and Internal network, is a device to help ensure the security of information, mainly by the service access rules, authentication tools, packet filtering and application Gateway 4 components, All data and information passing through this wall is filtered for purpose, creating a secure gateway between the Internet and the intranet to protect the intranet from unauthorized users.

Large-scale financial institutions, large-scale knowledge database and so on the information security requirements of enterprises have a sense of data protection, and small and medium-sized enterprises due to cost constraints or lack of awareness of the reasons, there is no need to install firewalls and other protection facilities to have an accurate understanding. So what specific role does firewall play in security and security of enterprise information?

1. Support Network security barriers

Firewall is set in the outside network and intranet, private network and public network between the level, not meet the application protocol data and traffic is not able to pass, so it can effectively filter out the factors that are unsafe for the enterprise, purify the network environment of the enterprise.

2. Improve network security Policy

Network security problems everywhere, instead of the security software distributed in the various host, we can deploy a firewall-centric security configuration scheme, with a firewall to achieve unified centralized management, so that both economic and easy to manage. For example, a one-time password authentication system based on the traditional plaintext password authentication can be centrally deployed on the fire wall.

3. Monitor computer and network activities

Firewalls can monitor the use of computers and networks in real time, generating logs and data statistics. Once the firewall is found suspicious action, will be timely alarm processing. Of course, the "manslaughter" situation has occurred, resulting in normal traffic can not be accessed, this we will be the deployment of the firewall to optimize the solution.

4, the protection of internal information leakage

The firewall can not only organize external bad programs and traffic intrusion, but also can set rules to prevent the internal information from others malicious steal.

Hostspace Data Center Firewall working principle is to monitor the DDoS attack traffic, send notifications to the traffic cleaning system, traffic cleaning system to open attack defense, through the application of routing technology, the original to the attack target IP traffic to the bypass deployment of the traffic cleaning system, The traffic being towed is the mixture of the attack traffic with normal traffic, and only the suspect traffic is pulled, while traffic to other destinations will be unaffected and forwarded to the normal path.

Of course, the security of the enterprise website and information can not rely solely on the firewall, but also to carry out disaster recovery backup, virus protection measures, inform the customer responsibility, standardize the correct network access, service access, local and remote user authentication, disk and data encryption, and cultivate good network usage habits, etc., to establish a comprehensive defense system , so as to realize the enterprise network risk pre-judgment and controllable.
