Despite the security risks and vulnerabilities will lead to higher costs, but the Internet is still the fastest, most convenient and safe place to trade one.For example, in a well-known Web site using your credit card may actually in a restaurant than you used it to pay more secure.But the fear of security vulnerabilities caused many companies to a security vulnerability in itself, than the more serious problem: on the security concerns so many people are reluctant to use the Internet to conduct business transactions.Not only safety but also to make people feel safe.
To solve this problem, businesses must install and maintain security solutions, to develop security policies, security measures, these measures are not only practical - need to look very effective.Enterprises must make their customers and potential customers to understand their work in safety.
Want to build their own network security policy, we must first understand the factors that endanger the security of the network.
Endanger corporate security factors:
Virus.In March 1999 for the first time in the Melissa virus appeared on the Internet global computer bits worth 80 million U.S. dollars resulted in the loss.
Trojan
Attacks, including reconnaissance attacks, access attacks, DoS attacks
Destructive process (Vandal)
Data Monitor
Social engineering
Junk mail (Spam)
Not difficult to see a variety of ways against the network, so we must play a role in network security solutions, it must integrate different types of conservation, to integrate them into the various parts of the network.The level of security more losses in the attack before the attack more likely to stop.
Below, we will focus on physical security of the three main levels: a secure connection, perimeter security and intrusion prevention.The current network security market, the type of network security products, are mostly in accordance with the above-mentioned three levels of physical security classification protection.
1, a secure connection
Virtual Private Network is a public network (such as the Internet) on the dedicated connection.They allow users to places far away from the physical network to work with in-house the same level of security to communicate with the enterprise network.
If we continue to use the building to describe the network, then the VPN is a kind of armored vehicles, which can be classified along the public highway will be sent information from the outside world where we are building.
