1. Limit the number of IP connections to 80 ports to a maximum of 10, which can be customized. The code is as follows Copy Code Iptables-i input-p TCP--dport 80-m connlimit--connlimit-above 10-j DROP 2. Use the recent module to limit the number of new requests in the same IP time, recent more features please refer to: Iptables Module recent application. The code is as follows Copy Code Iptables-a input-p TCP--dpor

1, ensure the security of the server systemThe first step is to ensure that the server software does not have any vulnerabilities to prevent attackers from invading. Make sure the server is up to date with the latest system and security patches. Remove unused services on the server and close unused ports. For Web sites running on the server, make sure that they have the latest patches and no security holes.2. Hide the server real IPServer front-end plus CDN Transfer (free Baidu Cloud acceleratio

The main 2 basic practical applications, mainly related to the ban Ping (IPv4) and the prohibition of UDP, that is, the use of the server to prevent hackers to outsource DDoS attack content. First, if there is no iptables prohibit ping echo 1 >/proc/sys/net/ipv4/icmp_echo_igore_all #开启echo 0 >/proc/sys/net/ipv4/icmp_echo_igore_all #关闭Second, the use of iptables rules to ban ping Iptables-a input-p ICMP--icmp-type 8-s 0/0-j DROP Third, using the Ip

The Windows system itself has many mechanisms that can be used to improve performance and security, many of which can be used to cope with high concurrent requests and DDoS attacks. Windows Server performance can be improved with the following configurations: First, to respond to high concurrent requests: 1, TCP connection delay wait time TcpTimedWaitDelay: This is the time that must elapse before TCP/IP can release a closed connection and reuse i

The penalty policy for this attack is, Further violations would proceed with these following actions: 1st violation-warning and shutdown of server. We'll allow hours for your to rectify the problem. The first time is a warning + shutdown, give 24 hours to solve the problem 2nd violation-immediate reformat of server. The second time is to format the server immediately 3rd violation-cancellation with no refund. The third time is to cancel the service without giving a refund To address this pr

DoS (Denial of service denial-of-service) and DDoS (distributed denial of service distributed Denial-of-service) attacks are one of the security threats to large Web sites and network servers. The attacks on Yahoo, Amazon and CNN in February 2000 were carved into the history of major security events. Because of its good attacking effect, SYN Flood has become the most popular DOS and DDoS attack method at pr

They share hardware, software licenses, and manage resources with maximum efficiency. For its users and applications, the operation and m

Technical support: VPs is divided into VPs with and without after-sales services. As the name suggests, the former provides comprehensive after-sales services, the latter provides basic after-sales services such as host machine or network fault detection and troubleshooting. At the same time, the former has a comprehensive after-sales service guarantee, so the price is much more expensive than the latter. W

Many of my friends found that someone in their VPS would try the root Password Brute Force. The purpose of this tutorial is to shield the password from logging on to SSH, instead of using only the key to log on to SSH.This greatly improves the security of VPS (except for program vulnerabilities)Note: In this example, the local environment is Linux. In Windows, refer to other tutorials on the network.Warning

The current project looks that

Basic configuration of iptables for VPS Security I have read the secure log and access log, and most of them are brute force cracking and scanning. Although the password of my brother is extremely complicated, it is not a problem to consume server resources, simply change the ssh port and ftp, and write an iptables file to slightly protect it. Another thing is Fail2Ban, which can automatically detect brute-force cracking. If the password is incorrect

The predecessor of CC attacks is DDOS attacks (Distributed Denial of attack ). The principles of DDOS attacks against TCP/IP protocol defects cannot be considered as defects, but when the Protocol was designed for decades ago, designers assumed that everyone was a good citizen who followed the rules of the game, now the Internet environment is much more complex than at the time, but it is still using the pr
