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 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.
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.
A widely used method to increase available bandwidth by 5% while staying within the selected payment plan, based on the way bandwidth is measured: first, during a month-long period, data transfer stats are collected, then 5% of the highest values are removed from further analysis, while the highest value from the rest is used as the basis for payment calculation.
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 software robot designed for executing certain actions determined by algorithms or rules. Bots and bot networks installed on vulnerable nodes are often used for executing DoS and DDoS attacks.
A way to implement a DoS attack providing a manifold increase in impact on a victim server: a small number of bots initiate sending a huge amount of forged packets or requests, which severely slow down or paralyze the attacked server that tries to process them. The approach is used, e.g., in attacks based on the DNS and NTP protocols.
The use of a software intermediary (proxy) that processes traffic in a certain way for subsequent sending to another software program. Specifically, security proxies process traffic in such a way so as to prevent unauthorized traffic access and minimize the threat of network attacks.
Using illegal ways of affecting computer networks or individual nodes in order to promote political causes. Hacktivists usually participate in protest movements and try to attract as much attention as possible to the ideas they stand for.
A piece of software code or module used for attacking vulnerable nodes in order to gain command and control over them, carry out a destructive action, or cause a denial of service (in DoS attacks).
A database containing information about known vulnerabilities, including their descriptions and links to websites with additional info. The project is sponsored by the United States Computer Emergency Readiness Team (US CERT) and maintained by MITRE Corp. nonprofit
