deploy the firewall in the network. However, in the networks of large enterprises, firewalls and Security routers play a different role in routing and security functions. What should they do if they correspond to professional firewalls in addition to secure routing, as well as software firewalls, UTM, and other products?
The Software Firewall runs on a specific computer and needs the support of the computer operating system pre-installed by the custo
other software products, need to be installed on computers and configured before they can be used.
Checkpoint is the most famous among Firewall vendors for their network-based software firewalls. To use this type of firewall, the network administrator must be familiar with the operating system platform. UTM (UnITed Threat Management) refers to unified Threat Management. In the industry, anti-virus, firewal

Who is the best or inferior to the two network protection solutions of medium and large enterprises? If you have a close view of these friends, you will surely have such questions. Let's hear what Dr. Zhang hongwen, CEO of wedge Networks, said. Zhang hongwen believes: "UTM i

However, both solutions have their respective drawbacks:

Although it is very professional, it is always difficult to reach the level of professional vendors at the application layer. Therefore, if you select a digital manufacturer, because the system is closed, the user must make all

1.1 Introduction to Mercator projectionGerhardus Mercator 1512-1594 was developed in 1569 as an equi-angular tangent cylindrical projection, in which the Earth was enclosed in a hollow cylinder, the standard weft is in tangent contact with the cylinder, and then it is assumed that there is
, which may easily cause ARP spoofing.
Due to the simple implementation of ARP spoofing blocking methods, most vendors in China use ARP spoofing blocking methods, especially for unregistered blocking and illegal access blocking.
Insufficient ARP spoofing Blocking
First, ARP spoofing blocking has a great impact on the network load. When ARP is working, the host is requested to send an Ethernet broadcast packet containing the desired IP address, the own
Many vendors are promoting the integration of wired and wireless LAN Security solutions, but some network security experts, such as the Ireland Power Supply Bureau (the electricity Supply board,esb), the IT security experts Ruairi Brennan do not think so. "Isolating wired and wireless networks makes the security vulnerabilities exist only in Wi-Fi networks," Brennan said. "The Wireless LAN of the power supply Bureau is made up of 60 Aruba network acce

Limitations of ARP spoofing BlockingFirst, ARP spoofing blocking has a great impact on the network load.When ARP is working, the host is requested to send an Ethernet broadcast packet containing the desired IP address, the owner of the target IP address then responds to the request host with a packet containing the IP address
Intel's McAfee products have also performed well.Smithers recommends that enterprises evaluating NGFW should consider which features will be used in their environments and study how the product performs when all required features are enabled."When you turn on all these features, everything will slow down. 10 Gbit/s products become 3 Gbit/s products, "Smithers pointed out that compared with NGFW, unified Threat Management devices (UTM) are more suitab

Therefore, fixing vulnerabilities in application security is not a simple process. For flexible protocols such as HTTP, multiple measures are required to ensure application security.

control one or two computers, now, you can use a website to attack other websites, infect users, and build botnets to launch distributed denial of service (DDoS) attacks ). Therefore, any enterprise should pay attention to the diversity and diversity of preventive measures and do not rely on a pure technology. With UTM, everything is fine.
