Overview In many network firewall products, the Linux operating system firewall software features significant. Like Linux, they have powerful features, mostly open software, not only for free use but also for source code disclosure. These advantages are not comparable to other fir

Although some of the independent development, but did not master the whole line of core technology, product stability Sex remains to be examined. Using the first method to produce false NP firewall, its final trial effect and X86 system is not fundamentally different; for the latter two ways to create a
In recent years, with the large-scale application of Gigabit Networks in China, users' requirements for gigabit firewalls have gradually increased. In many network environments, the traditional Firewall Based on the X86 architecture cannot meet the high throughput and low latency requirements of the gigabit firewall. Therefore, the two new technologies, network Processor and ASIC technologies have become th

Before studying this issue, let's talk about DDOS: What is DDOS: DDoS (Distributed Denial of Service) attacks are simple and fatal network attacks by exploiting TCP/IP protocol vulnerabilities. Due to the session mechanism vulnerabilities of TCP/IP protocol, therefore, there is no direct and effective defense means. A large number of instances prove that the use of traditional devices for passive defense is basically futile, and the existing firewall
Www.bkjia.com: an old article written before January 1, year 45"Will hackers give me their ideas ?" That's right. hackers just want to crack the fly with eggs and see the light from system vulnerabilities! Okay. How can we protect your network? Computer experts may propose you to install the network firewall as soon as they open their mouths:What is a firewall?A firewal
resources, you can consider building a region called "Demilitarized Zone" DMZ. DMZ can be understood as a special network area different from the Internet or intranet. DMZ usually stores some public servers without confidential information, such as Web, Mail, and FTP. In this way, visitors from the Internet can access services in DMZ, but they cannot access company secrets or private information stored in the intranet. Even if the DMZ server is damaged, the confidential information in the Intra
records, and as the application of the filter increases, the number of rules tends to go up to the degree of geometric progression, which is a great test of the load on the firewall, the use of different processors to complete different functions may be one of the solutions, For example, using the coprocessor of the integrated proprietary algorithm to deal with the rule judgment specifically, in some aspect of the
rules, and VPN connections. Check Point virtual devices can be integrated with various Amazon instance types, and also support the Check Point "software blade" function, which provides a modular approach to security performance sets. Check Point is the only product that has proven in the firewall field and can be fully integrated into Amazon's market. Cisco and Juniper do not have any products in the AWS m
used to treat the server, so the server will be very dangerous. Similarly, the security level of the server cannot be used to treat the client, which makes the user feel inconvenient. To provide different security levels for different resources, you can consider building a region called "Demilitarized Zone" (DMZ. DMZ can be understood as a special network area different from the Internet or intranet. DMZ usually stores some public servers without confidential information, such as Web, Mail,
cannot access company secrets or private information stored in the intranet. Even if the DMZ server is damaged, the confidential information in the Intranet is not affected. Many firewall products provide DMZ interfaces. Hardware firewalls use dedicated hardware chips, so they have absolute advantages in performance and traffic. The cost-effectiveness of the software f
. Setting up TelnetTelnet has a version of the change. Before the PIX OS 5.0 (the version number of the PIX OS), the PIX can only be accessed via Telnet from hosts on the internal network. In PIX OS 5.0 and later versions, Telnet to PIX Access can be enabled on all interfaces. When you want to telnet to the PIX firewall from the external interface, the Telnet traffic needs to be protected with IPSec, which means that the user must configure the PIX to

The operating system should be configured first to ensure the security of the browser, email client, and application. After the system is configured, the firewall is used, A security alarm is triggered when a hidden program attempts to access the Internet from a computer. Therefore, a personal firewall must be configured in the computer. Computer users have a lot in common with house owners who usually want
to prevent attacks. Most security policies are based on command lines, the formulation of security rules is relatively complex, and the probability of configuration errors is high. The default configuration of the NetEye firewall not only prevents various attacks, but also ensures security. The security policy is developed based on a Chinese GUI management tool. The security policy is user-friendly, simple configuration and low error rate. 4. Differe
