DNS Security is a method of securing the Domain Name System. In potentially simple terms, DNS Security is a way for Internet users to identify themselves with their Domain Name and authenticate who they say they are when communicating electronically online.
The Domain Name System (DNS) is how devices on the internet find each other and communicate by associating an easy-to-remember word or string of characters (known as a domain name or website address) with the numerical addresses used in transmissions across the internet. For example, when you type in “google.com” into your web browser, your computer sends a request to its DNS server, which then sends a query to Google’s DNS server requesting it to resolve that domain name (google.com) into an IP address (for example, 172.217.5.110). When you set up your home router, it will assign itself as the DNS server for all devices on your local network; this allows your computer to use your home’s IP address every time that you type “google.com” into your browser instead of having to remember that IP address or type it in manually each time you want to access Google’s search engine.
DNS Security is a way of making sure that all communications between user and domain name are secure. If implemented correctly, DNS Security makes it so that users can be assured that they are communicating with the correct website when sending information over the internet, receiving information from websites, and transferring money.
It was not until 2009 that the United States and other countries began to set up frameworks and best practices for implementing DNS Security, and it is still a growing concern today. While DNS Security does help keep internet users safe from many different types of attacks, such as DDOS (Denial of Service) attacks or Man-in-the-Middle Attacks, there are still ways for certain cybercriminals to get around these security protocols to hack into user accounts and steal information. Because of this, both internet users and website owners alike need to stay aware of how secure their specific configurations are so that they can take action if anything goes wrong. Furthermore, because the cyber world constantly changes, websites and email providers must frequently update their security protocols to keep up with new kinds of cyberattacks and bad actors. In addition, online users should take steps to protect themselves from becoming victims of these attacks by updating their passwords regularly, checking the security settings on any accounts that they frequently use, and being aware of possible phishing scams or fake emails from unknown senders.
While DNS Security is by no means perfect and can be blocked if certain electronic traffic is deliberately slowed down or halted altogether to hack through firewalls, it does provide a basic level of protection against hackers. Additionally, many websites have begun using SSL certificates in conjunction with DNS Security to provide even greater protection than either system could offer by itself.
