In computing, a denial-of-service attack is a cyber-attack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to a network. Denial of service is typically accomplished by flooding the targeted machine or resource with superfluous requests in an attempt to overload systems and prevent some or all legitimate requests from being fulfilled.
Akamai Technologies, Inc. is an American content delivery network (CDN), cybersecurity, and cloud service company, providing web and Internet security services. The company operates a network of servers worldwide and rents the capacity of the servers to customers wanting to increase the efficiency of their websites by using Akamai owned servers located near the user. When a user navigates to the URL of an Akamai customer, their browser is directed by Akamai's domain name system to a proximal edge server that can serve the requested content. Akamai's mapping system assigns each user to a proximal edge server using sophisticated algorithms such as stable matching and consistent hashing, enabling more reliable and faster web downloads. Further, Akamai implements DDoS mitigation and other security services in its edge server platform.
A botnet is a group of Internet-connected devices, each of which runs one or more bots. Botnets can be used to perform Distributed Denial-of-Service (DDoS) attacks, steal data, send spam, and allow the attacker to access the device and its connection. The owner can control the botnet using command and control (C&C) software. The word "botnet" is a portmanteau of the words "robot" and "network". The term is usually used with a negative or malicious connotation.
Internet security is a branch of computer security. It encompasses the Internet, browser security, web site security, and network security as it applies to other applications or operating systems as a whole. Its objective is to establish rules and measures to use against attacks over the Internet. The Internet is an inherently insecure channel for information exchange, with high risk of intrusion or fraud, such as phishing, online viruses, trojans, ransomware and worms.
A content delivery network, or content distribution network (CDN), is a geographically distributed network of proxy servers and their data centers. The goal is to provide high availability and performance by distributing the service spatially relative to end users. CDNs came into existence in the late 1990s as a means for alleviating the performance bottlenecks of the Internet as the Internet was starting to become a mission-critical medium for people and enterprises. Since then, CDNs have grown to serve a large portion of the Internet content today, including web objects, downloadable objects, applications, live streaming media, on-demand streaming media, and social media sites.
Norton Internet Security, developed by Symantec Corporation, is a discontinued computer program that provides malware protection and removal during a subscription period.

With the release of the 2015 line in summer 2014, Symantec officially retired Norton Internet Security after 14 years as the chief Norton product. It was superseded by Norton Security, a rechristened adaptation of the Norton 360 security suite.
A dedicated hosting service, dedicated server, or managed hosting service is a type of Internet hosting in which the client leases an entire server not shared with anyone else. This is more flexible than shared hosting, as organizations have full control over the server(s), including choice of operating system, hardware, etc.
Web scraping, web harvesting, or web data extraction is data scraping used for extracting data from websites. Web scraping software may directly access the World Wide Web using the Hypertext Transfer Protocol or a web browser. While web scraping can be done manually by a software user, the term typically refers to automated processes implemented using a bot or web crawler. It is a form of copying in which specific data is gathered and copied from the web, typically into a central local database or spreadsheet, for later retrieval or analysis.

Blue Frog was a freely-licensed anti-spam tool produced by Blue Security Inc. and operated as part of a community-based system which tried to persuade spammers to remove community members' addresses from their mailing lists by automating the complaint process for each user as spam is received. Blue Security maintained these addresses in a hashed form in a Do Not Intrude Registry, and spammers could use free tools to clean their lists. The tool was discontinued in 2006.
Website monitoring is the process of testing and verifying that end-users can interact with a website or web application as expected. Website monitoring are often used by businesses to ensure website uptime, performance, and functionality is as expected.
In networking, a black hole, also known as a block hole, refers to a place in the network where incoming or outgoing traffic is silently discarded, without informing the source that the data did not reach its intended recipient.
Fail2ban is an intrusion prevention software framework. Written in the Python programming language, it is designed to prevent brute-force attacks. It is able to run on POSIX systems that have an interface to a packet-control system or firewall installed locally, such as iptables or TCP Wrapper.
Network behavior anomaly detection (NBAD) is a security technique that provides network security threat detection. It is a complementary technology to systems that detect security threats based on packet signatures.
Imperva Incapsula is an American cloud-based application delivery platform. It uses a global content delivery network to provide web application security, DDoS mitigation, content caching, application delivery, load balancing and failover services.
DDoS mitigation is a set of network management techniques and/or tools, for resisting or mitigating the impact of distributed denial-of-service (DDoS) attacks on networks attached to the Internet, by protecting the target, and relay networks. DDoS attacks are a constant threat to businesses and organizations, by delaying service performance, or by shutting down a website entirely.
Instart was an American multinational computer technology corporation, headquartered in Palo Alto, California. The company specialized primarily in improving online content delivery speeds. The company also offered software designed to increase online advertising by accelerating the rate at which ads loaded and preventing blockers or filters from blocking ads.
Runtime application self-protection (RASP) is a security technology that uses runtime instrumentation to detect and block computer attacks by taking advantage of information from inside the running software. The technology differs from perimeter-based protections such as firewalls, that can only detect and block attacks by using network information without contextual awareness. RASP technology is said to improve the security of software by monitoring its inputs, and blocking those that could allow attacks, while protecting the runtime environment from unwanted changes and tampering. RASP-protected applications rely less on external devices like firewalls to provide runtime security protection. When a threat is detected RASP can prevent exploitation and possibly take other actions, including terminating a user's session, shutting the application down, alerting security personnel and sending a warning to the user. RASP aims to close the gap left by application security testing and network perimeter controls, neither of which have enough insight into real-time data and event flows to either prevent vulnerabilities slipping through the review process or block new threats that were unforeseen during development.
