functions, such as: Juniper, Extreme, Foundry, h3c. For Cisco, NetFlow has several versions, such as: V5, V7, V8, V9. At present NetFlow V5 is the mainstream. So this article is focused on NetFlowV5, what are the basic elements of this version of the packet, first from flow. For more information, see The open source secure operation dimensional plane-ossim best practices. In the book, not only how to deploy the NetFlow system, how to use it to analyz

　The principle of fault detection in firewall systemAs most computers use Windows systems, firewalls also have their own systems, usually Linux, and computers, firewalls, if there is a failure, can be divided into software failures and hardware failures, hardware failures are more obvious, easy to judge, and software failure because the firewall is usually no information display or display of the small amount, it is not easy to judge, this need through the terminal software, the use of dedicated

network Cloud, and the solution was virtual cluster exchange technology. Virtual cluster switching is a technology that manages a large number of top-level rack switches as a whole through virtual racks. "Although flat networks were effective and manageable before they were designed, the problem was that servers from one rack may negatively affect the performance of other components of the data center; it is also difficult to easily determine which parts of the Rack are faulty, "Hasson explaine

devices, which makes designers crazy. This also makes the designer feel that the site must adapt to the user's every custom device. In fact, this is not difficult, you can easily make your site suitable for each device.5.

Configure the syslogs of Netscreen to be stored on the Linux Syslog Server-Linux Enterprise Application-Linux server application. For details, see the following. When I went on a business trip to Hebei province two days ago to debug the Netscreen500 firewall of Juniper for a Netcom company, they asked me to store the logs recorded by the firewall to the log server created on the Linux platform, if you still have such information, we will discuss and s

I have used this combination to replace EMC shared storage in many occasions. After all, more than 0.3 million of the price is not acceptable to every customer.18. No matter how mature the design scheme is, we recommend that you configure the Nagios monitoring machine to monitor our servers in real time. Email and SMS Alarms can be enabled. Afte

world, and they make me understand that faith, diligence and determination can make anything possible!The writing of this book has been helped by a lot of people, and without their help the book is impossible to complete. Thank them for their efforts to improve the final draft of this book. It should be noted that I have done my best to correct the errors identified by the reviewer and to describe the various protocols and mechanisms accurately. I am personally responsible for any other errors

Security vulnerabilities in the LAN One thing you need to keep in mind is that you should never underestimate the skills and intentions that come from within. Most of the vulnerabilities I've found in virtual environments use free tools or are easy to dev

efficiency and accuracy of security protection. For example, the application software and files to give security reputation evaluation, guide network users download behavior, through the issuance of authoritative IP reputation information, guide security equipment to automatically generate protection strategy, see "Unix/linux Network log analysis and Traffic Monitoring" section 2.1.5). Using a passive strategy to buy large bandwidth can also effectively mitigate the threat of DDoS attacks.6). B
