As a follow-up to the last article on what internet censorship is, the regions it impacts, and the people it affects, this post will examine different methods used by governments to guarantee the effectiveness of their internet control programs.
The government imposes internet censorship via a variety of techniques or technologies. Without rigorous enforcement of internet censorship, cyberspace will remain uncontrollable in an intended manner. Several of the government’s techniques for enforcing internet censorship are discussed below.
The government’s internet censorship technologies
The following are several technological blocking methods that may be used to restrict or suppress content for customers.
Blocking IP addresses
The government may impose internet censorship by blacklisting the IP addresses of already-banned websites, causing internet service providers to reject requests for access to the site.
DNS (Domain Name System) blocking
The authorities have the authority to ban or deregister a domain that publishes content that the government deems detrimental to the public. This renders the website inaccessible to visitors’ browsers; as a consequence, the domain becomes unavailable.
Filtering by Uniform Resource Locator (URL) or by Keyword
This technique does a keyword scan on the URL. Once the prohibited terms are discovered in the URL, the whole URL address is blocked, and the user is unable to visit the website.
This is a sophisticated blocking technique that focuses on a website’s content. It searches for prohibited terms in the content being downloaded or sent. If the content includes a prohibited keyword, the connection to the source may be terminated.
Disconnection from the network
The government may impose internet censorship by fully shutting down the internet service in such a manner that it seems as if the network is experiencing problems.
Removal of search results and portal censorship
The technique works by analyzing search results for particular phrases and deleting them entirely from search engines.
Attacks against computer networks
This takes the form of denial of service (DoS) assaults, which prohibit users from accessing services when a website has been deemed a danger.
Possessing control of the internet
The government may censor the internet directly by becoming an internet service provider (ISP), which gives the government the authority to do as it pleases.
