specified http header variable as the key and add the redis counter. The remaining time of the preceding step is the timeout time. Check the redis counter. If the frequency limit is reached, 403 forbid The entire nginx cluster uses a unified redis server and can use keys for hash grouping to support performance expansion. To cope with the following attacks: Frequent access from a single IP Address: The key is binary_remote_addr, and access from t

Currently, the vro technology has been very well developed. So I have studied how to use the vro technology to prevent malicious cyberattacks. I would like to share with you here and hope it will be useful to you. In addition to ADSL dial-up Internet access, residential broadband Internet access is also a common Internet access method. If you use residential broadband Internet access, Do you think vro technology is just an Internet tool? Otherwise, yo

In addition to hacker attacks, ADSL users are still threatened by viruses and Trojans. Despite the fact that ADSL users have installed professional antivirus software and firewall software on their computers, viruses or Trojans are not recommended because a large number of viruses or Trojans are already capable of Eliminating viruses, you can easily bypass the strict monitoring of anti-virus software. "What we are most afraid of now is not to use anti

of D. Forward the data packets sent by A to C, just like A router. However, if D sends ICMP redirection, the entire plan is interrupted. D. directly modify and forward the entire package, capture all the packets sent by A to C, and then forward them to C, the packets received by C are completely considered sent from. However, the packets sent by C are directly transmitted to A, if the ARP spoofing to C is performed again. Now D has completely become

WPA or WPA2 encryption, it can also be cracked, but the brute-force method is used to crack, that is, the software performs one-by-one guess, while WPA2 is more likely to be outputted.Defense measures against network attacks by others1. encrypted by WPA/WPA2-PSKHackers generally use dummies to crack software. They can only crack WEP-encrypted wireless signals. A Slightly advanced hacker will use packet capture tools to analyze the content in the data

how to prevent network attacks! We take DIR-605 wireless router as an example, to see what needs to be set, we can avoid being rubbed. Step 1: Modify the SSIDLog on to the vro configuration page and click "wireless installation ". As you can see, the SSID in the default vro status is dlink and the SSID is broadcast. Modify the SSID name to testwpa.

It has become a challenge to seize hackers who secretly put their hands on ADSL users' computers. In fact, as long as you understand the common techniques used by hackers to attack ADSL users and formulate corresponding security policies, you can also comprehensively prevent hacker attacks. Next, I will introduce the methods that hackers often use to attack ADSL users' computers. Hacker attack ADSL user exp

-company employees carry notebooks, Tablet computer or mobile phone, etc. access to the local area network, access to important internal sharing files, access to the Internet, such as foreign computers or network equipment to the enterprise's trade secrets and intangible assets of the security cause a major hidden danger; In addition, some skilled outsiders may also run some sniffer software, Network grab software or hacker software to steal the company's trade secrets, employee privacy informat

The netsh command under win7 can effectively prevent ARP attacks in the LAN.The following is how to use it:1. Right-click the cmd. EXE command in windows \ system32 on Windows 7 7 and run it as an administrator;Let's take a look at the ARP table status.ARP-Interface: 192.168.1.1 00-19-e0-e0-76-ca dynamic192.168.1.100 00-1f-c6-31-8a-4b dynamic192.168.1.255 FF-FF static224.0.0.22 01-00-5e-00-00-16 static224.0

1. Hide IP addresses If a hacker wants to launch an attack on us, he must first find our IP address. Otherwise, he cannot start. The following three methods are commonly used to hide IP addresses: 1. Use Proxy Server: If we browse websites, chat, BBS, and so on, then the website is left on the Proxy Server rather than our website. 2. Use tool software: Norton Internet Security has the function of hiding IP addresses. This method is invalid if your computer's front-end has a

Many of us are familiar with the use of wireless routers, but how can we defend against the endless intrusion of users? The following measures are helpful to you. When using wireless routers for wireless surfing, our neighbors may accidentally break into the local wireless network. These neighbors enjoy the bandwidth we provide for free, you may try to log on to the background management interface of the local wireless router to launch illegal

We are all concerned about the prevention of network theft by others. So what aspects should we start with to prevent illegal network user intrusion? When using wireless routers for wireless surfing, our neighbors may accidentally break into the local wireless network. These neighbors enjoy the bandwidth we provide for free, you may try to log on to the background management interface of the local wireless router
