connection attacks Slowloris is easy to defend against attacks. There are two main solutions: The first is to calculate the length of each TCP connection and calculate the number of packets passed per unit time for precise identification. In a TCP connection, too few HTTP messages and too many packets are abnormal. too few may be slow connection attacks, and too many may be HTTP Flood attacks using the HTTP1.1 protocol, send multiple HTTP requests in a TCP connection. The second is to limit t

and the domain keys and other new protocols can help combat phishing attacks. As a result, IT managers believe that a "reputation based" system, such as Spamhaus or SPAMCOP, which is available for free use, can be effectively integrated with other anti-spam tools. In fact, this is not impossible, but requires expertise in email Security Gateway design and open source applications. Antivirus functionality is also the function of any mail security net

The source IP address is regarded as a slow connection attack, and the connection is interrupted and added to the blacklist. 4. New attack methods DNS reflection/amplification attacks use the DNS infrastructure on the Internet to enlarge the traffic generated by attacks. DNS is an important part of

The Rfc-igno-rant.org goes further by blacklisting email servers that violate RFC 821 and 2821 (RFC 821 and 2821 are the main specification for SMTP communication ). Unfortunately, a considerable number of legitimate email servers violate these rules due to poor design or incorrect implementation. Users who use these email servers may be blacklisted by the rfc-ignorant.org, even if they are not spammers. Although these websites should use complian
