There are many benefits to virtual servers, but are their security issues completely compromised? How do I ensure security? There are 10 positive steps you can take. The major problem with data center virtualization in the 2007 is "How much money and time can this technology save?" "And by 2008, the question will become" How safe will we be to adopt this technology? "It's a very difficult question to answer." A large number of vendors and consultants desperately selling virtualized products and services disagree on the risks and how to prevent them. At the same time, some security researchers are also trumpeting the risks of the theory.

First, the user faces the risk at present, most application system mainly uses the traditional password authentication method to carry on the identity authentication. This kind of authentication way faces many attacks and the leakage risk, for example: The network eavesdropping (Sniffer), the authentication information interception/Replay (Record/replay), the virus, the hacker and so on, the traditional password authentication way already cannot satisfy the large-scale network application security authentication demand. 498) this.width=498 ' OnMouseWheel = ' javascript:return big (th ...

The router is an important bridge for the LAN to connect the external network, is an indispensable part in the network system, and also the Frontier Gateway of the network security. But the maintenance of the router is rarely appreciated. Just imagine, if the router even its own security is not guaranteed, the entire network there is no security to say. Therefore, in the network security management, the router must be properly planned and configured to take the necessary security measures to avoid the security problems of the router to the entire network system to bring loopholes and risks. We are here to introduce some of the router to enhance the security of the measures and methods, let me ...

Wireless networks were once considered a game of hackers and malicious attacks. However, wireless networks are fast becoming a more secure means of communication than wired networks. With VPN, WPA (Wi-Fi Protected Access) and 802.1x WPA2 encryption and identity technology, the theory that wireless LANs are equal to insecure LANs is outdated. In many cases, your wireless network is more secure than your wired network, said Bill Terrill, senior analyst at Burton Group, a market research firm based in Utah State Midvale.

Why use a VLAN? The implementation of VLAN is a logical division of users, so that users in different VLANs can not communicate directly. This technology facilitates implementation and saves money. However, with the application of VLAN more and more wide, and VLAN-related security management problems are more and more serious. The application of VLAN technology provides a strategy method based on management mode for network security, we can choose different VLAN partition methods according to the characteristics of enterprise network management. Although the network security to a certain extent has been guaranteed, but ...

The IDC report shows that the switch market has maintained a high growth momentum in recent years, and the market is expected to reach $1.51 billion by 2009. Switch in the enterprise network occupies an important position, is usually the core of the entire network, this position makes it become the focus of hacker intrusion and virus rampant, in order to protect their own network security, enterprises need to have a full understanding of the switch vulnerabilities on the local area network. The following are five ways to exploit the switch vulnerabilities. VLAN jump attack virtual local area network (VLAN) is a method to segment broadcast domain. VLANs are also often used for web ...

In some ways, securing your computer is a full-time job. The problem is even more complicated when you think about wireless security. For those traveling outside the wireless network, whether they use a wireless access point in a café, an airport, or a hotel where they spend the night, one important concern is that they never know the security of the network they use unless they know it is not. For example, for a network of coffee shops, this is true: because they are open to everyone, you can't finish ...

The use of computers is becoming an adventure because the data we store and deliver on our computers, personal privacy, trade secrets, and so on are being increasingly threatened and the internet is no longer secure. Today, traditional viruses and junk mail have new accomplices-more dangerous spyware and adware.

Now there are a variety of more and more detailed "IP address library", to know some ADSL users of the IP is very easy things. How to defend your network security? Consider the following methods. One, unhide folders if you use the Windows 2000/XP system, right click on the C disk or other disk, choose "Sharing", you will be surprised to find that it has been set to "total ..."

The NBA is another security model, not only to meet compliance requirements, but also to be part of an enterprise's deep defense architecture. Brandon Greenwood is the network operation and security manager of Utah State, a Xango company that produces nutritional additives. He thinks the NBA is another security model. For them, adopting the NBA is not just about implementing a compliance program, but also a best practice as part of a defense-in-depth architecture. Xango chose the Sourcefire Company's NBA to help protect the spread of the whole ...

1. When there is a failure to check the network card first in the LAN, the phenomenon of internet is often occurring, once encountered such a problem, we should first carefully check the network of the machine, network card settings are normal. When checking, we can open the Control Panel/System/device Management/Network adapter Setup window in turn by using the mouse. Check for interrupts and I/O address conflicts in this window (it is better to set the interrupts for each machine to be the same for comparison) until "This device is working properly" in the properties of the network adapter. And in the "Network Neighborhood" can at least find ...

First, Nat/alg way ordinary NAT is to modify the UDP or TCP message header address information to achieve address conversion, but for VoIP applications, in the UDP net load also need to take address information, ALG means that in the private network of VoIP terminals in the net load to fill in the private network address, This address information is modified to an external address on Nat via Nat. The recognition of voice and video protocols (H323, SIP, mgcp/h248) and the control of Nat/firewall, and each additional new application will require ...

The wide use of open-mail open source technology enables hackers to crack digital signatures and get mail content. The problem is how to protect your e-mail messages from being compromised through the GNU Privacy Guardian. If GPG (GPG is a set of toolset for secure communication and data storage that can be encrypted and digitally signed) is not properly used, it is not possible to obtain security recognition from the information. It is entirely possible to insert additional information before and after the data is encrypted, and it is safe to mistake the user for the data. Using cryptographic techniques to authenticate or encrypt e-mail messages is quite dangerous. ...

Even today, VoIP technology is widely used, security is still repeatedly questioned. Peter Cox, a British security expert and founder of the firewall company Borderware, announced recently that VoIP phones based on the internet are extremely insecure and easy for hackers to exploit. To substantiate this view, he developed a "proof-of-concept" (proof-of-concept) software siptap that could eavesdrop on VoIP Internet telephony. The software utilizes a Trojan horse software installed on the corporate network to successfully access the VoIP network ...
