ColorSoft (formerly Anti ARP Sniffer ). The biggest feature of the software is that the system kernel layer intercepts false ARP packets and proactively notifies the gateway of the correct MAC address of the Local Machine. This ensures that the computer where the software is installed can access the Internet normally, it also intercepts external ARP attacks on the local machine. If an internal ARP attack is detected, the attacker can directly process

1. ARP Spoofing In an IP-based communication Intranet, we can use ARP spoofing. The fundamental principle of ARP spoofing attacks is that computers maintain an ARP high-speed cache, in addition, the ARP high-speed cache is constantly updated as the computer continuously sends ARP requests and receives ARP responses. The purpose of ARP high-speed cache is to map the IP address of the machine to the MAC address. You can use arp commands to view your ARP cache. Assume machine A: the IP address is

RTP (Real Time Transport Protocol) RTP is a transmission protocol for multimedia data streams over the Internet.Rfc1889Release. RTP is defined to work during one-to-one or one-to-many transmission. It aims to provide time information and implement stream synchronization. Typical RTP applications are built on UDP, but can also work on TCP, ATM, and other protocols. RTP itself only guarantees the transmissio

The IP protocol is the most important protocol in the family of TCP/IP protocols, which provides unreliable, non-connected datagram transport services. So understanding IP protocols is critical to our learning network.IP headerImportant Field Introduction：4bit First ministerial degree: in 4 bytes, determines the IP head of the largest minister of 15*4=60, the general IP datagram header length of 20, at this

IMAP was an email acquisition protocol developed by Stanford University in 1986. Its main role is that the mail client (for example, Ms Outlook Express) can obtain mail info

punctured.◇ ScalabilityAs I said earlier, HTTPS is equivalent to "HTTP over SSL".If the SSL protocol is designed to be "scalable" enough, it can be paired with other application-layer protocols in addition to HTTP. Wouldn't it be beautiful?Now it seems that the person who designed the SSL did compare cattle. Today's SSL/TLS can be combined with many common application layer protocols such as FTP, SMTP, POP, Telnet to enhance the security of these app

Both TCP and UDP are port-based protocols. TCP has links, and UDP has no links. The TCP protocol also drops packets (network problems, the data may be gone)The application is sent to the operating system's cache, and the operating system is removed from the cache, and once the data is lost, it is completely gone. TCP is reliable because the data in its own cache is emptied after it receives a confirmation message.How UDP works I took it out of my own

Commands and responses to the SMTP protocol From the previous communication model, you can see that the SMTP protocol's session between sending SMTP and receiving SMTP is done by sending SMTP commands and receiving an answer to SMTP feedback. After the communication link is established, Send SMTP send mail command message sender, if receive SMTP at this time can receive mail then make OK answer, and then send SMTP continue to Issue RCPT command to con
