Enterprise Desktop systems. Due to cost and management, we cannot place an IDS Device next to each access layer switch. Deploy IDS at the distribution layer or core layer. For the distribution layer or core layer that collects hundreds of thousands of 7th Mbit/s/Ethernet traffic, the IDS that work on Layer 1 cannot process massive data, therefore, it is impractical to monitor all traffic without any choice. How can we find a targeted, effective, and economically scalable solution? You can use t

long time, I found that the CPU usage of the system has been around 15%, which indicates that after the switch platform software is upgraded to the latest version, the switch can remain dynamic. Therefore, when the LAN switch remains unstable, we should check the version of the corresponding platform software in time. Once the switch system version is found to be low, we must upgrade it in time, this can solve many hidden failures caused by the switch's own performance. Collect suspicious traff

Once the switch system version is found to be low, we must upgrade it in time, this can solve many hidden failures caused by the switch's own performance. Collect suspicious traffic. Once the suspicious traffic is detected, We need to capture these packets to determine whether the abnormal traffic has undergone a new worm attack. As described above, Netflow does not perform in-depth an

VPS, ubuntu12.04. R2 indicates that many routers have no control permissions. To perform an intranet penetration test, you need more information. We also add a public network VPS (win2008R) to set up a traffic monitoring server to analyze the daily Intranet traffic and behavior. Win2008 builds a netflow server and configures netflow on R1 to observe Intranet traffic information. There are a lot of

Spectre Meltdown vulnerability patch repair security tips Spectre/Meltdown events seem to have entered the second stage-various vendors have released their own repair solutions. However, it does not seem as smooth as imagined. The industrial control system vendor Wonderware said that the Meltdown patch affected the stability of the industrial control system, while the SolarWinds found that the patch caused a soaring CPU usage.

Traditionally, NetFlow export data for switches and routers are deployed, such as IP source and destination addresses, source and destination ports, 3-tier protocol types, and service classes. However, both Ipfix and

Microsoft Word users are said to have used only 10% of the software's functionality, as well as those who manage the corporate LAN switches and routers. This situation causes the enterprise to pay the unnecessary purchase and the human cost. An informal survey by some major switch and router vendors shows that users only use less than half of their system's capabilities. Some of the neglected functions focus on the specific functions of network management and security, these vendors say. Broca

After your server is hosted and shelved in the data center, it will officially provide external services for 7x24 hours. The incoming and outgoing data packets in the server have a certain amount of traffic, and the data center will also monitor and control the traffic on your server. When traffic on your server is abnormal, they will immediately control the traffic.Common traffic monitoring software include DU Meter, MRTG, PRTG, and SolarWinds. Curre
