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

CenOS gateway ProblemsA problem occurred when we used PacketiX VPN. After a long time, I did not solve the problem, so I found out the problem by looking for their technical staff to completely simulate our network environment. It is representative and I will share it with you.The network environment is as follows:The headquarters of the company uses the hardware firewall of Juniper. The intranet gateway is 10.50.201.1, And the PacketiX (Ex) VPNServer

serious as you think. You can consider using it in an online environment. DRDB + Heartbeat is a mature application and we recommend that you master it. 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

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

has now been acquired by Juniper) as well as TBD Networks. In this way, you'll also get better visibility, finer control, and better system performance and scalability in your virtual environment. 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

If the scale is small, the room condition is general, that may consider in the system to use some anti-DDoS the small tool, like the DDoS Deflate, its official website address is http://deflate.medialayer.com, It is a free script to defend against and mitiga

With the development of virtualized infrastructures, many organizations feel that in these environments, they need to leverage and extend existing physical network security tools to provide greater visibility and functionality. Virtual Firewall is one of the main virtual security products available today, and there are many selectivity, Check Point has VPN-1 Firewall virtual version (VE), Cisco provides virtual gateway product simulation ASA firewall.
