Term
P2P is an efficient method of transferring data over the Internet. The best-known example of a P2P network is torrent.
A firewall is a type of system used to monitor connections between computer networks. As one of the first responses to malicious activity carried out over the Internet, firewalls have become a standard part of corporate, government, and private networks.
A proxy server is a system that routes traffic between networks or protocols. The proxy server has its own IP address, so it acts as an intermediary between your computer and the Internet.
Domain Name System blacklists, also known as DNSBL or DNS blacklists, are spam blocking lists that allow the website administrator to block messages from certain systems.
To establish a reliable connection, TCP uses a process called the “three-way handshake”. The established connection will be full-duplex, that is, both channels can transmit information simultaneously, and they also synchronize (SYN) and acknowledge (ACK) with each other.
To effectively protect information, it is necessary to understand what is happening with traffic within the network. However, this is not the easiest task, as it is further complicated by the widespread use of the Transport Layer Security (TLS) protocol, which interferes with traditional methods of monitoring network security. But then TLS fingerprinting comes to the rescue - a method that will help you understand the traffic without depriving you of any advantages of the TLS protocol. For each client, the “fingerprint " remains static from session to session.
Malicious actions impacting web resources on the Internet. Attacks of this kind are usually classified into mass and targeted types. Attacks of the first type target a site as a whole and are usually automated. In mass attacks, attackers use their knowledge of popular tools and widespread vulnerabilities. Targeted attacks, on the other hand, are usually carried out by manually searching for vulnerabilities and exploiting them. The damage inflicted by an attack of this type can be fatal.
A network level protocol used in data networks based on Internet standards. Ensures data transmission from one Internet node to any other by “slicing” it and “packaging” into IP packets.
The time period from the moment a data packet was sent until receiving an acknowledgment of its receipt.
A key link characteristic, the maximum data transfer rate achievable via the link.
The size of a buffer used when receiving a packet. Essentially, this is the amount of data sent in one TCP packet. By default, TCP window size can be no more than 65535 bytes. With the window scale option, however, the window size value can be up to 1Gb.
A piece of data locally stored by a Web client, characterizing a user from the viewpoint of a server accessed by the user. Possible attributes that can be stored in a cookie include e-mail address, personal preferences and settings, session state data, stats, etc. When data is exchanged with a Web server without encryption, cookies could be intercepted and tampered with.
