The Internet is like a big neighborhood, and DNS is a friendly guide that helps your computer find websites. But like any place, it is not completely safe. Bad actors can screw up this guide and take you to wrong websites..
Three DNS Attacks Unveiled: Spoofing, Amplification, and Cache Poisoning
- DNS Spoofing: A type of attack where malicious actors manipulate DNS responses to redirect users to fraudulent websites, leading to potential data theft or phishing.
- DNS Amplification: Exploiting open DNS servers to amplify traffic directed at a target, overwhelming it with a flood of requests and causing a denial-of-service (DoS) attack.
- DNS Cache Poisoning: Injecting false DNS records into a server's cache, leading it to redirect users to malicious sites, potentially compromising the security and integrity of the network.
To improve security, there is a superhero called DNSSEC Domain Name System Security Extensions. It's like putting a special stamp on a guide and giving advice. Before the guide (DNS server) tells your computer where to go, it signs its advice with a special key and creates a unique token. When your computer receives this advice, it checks the permission against an already existing key. If the dots match, the tip is reliable and the site you are on is real and not fake..
To be even safer, there are some rules to follow. Keep track of the directory and traffic, update your security tools and use some internet gateway (firewall). There are also services that can block bad neighborhoods on the Internet, which adds an extra layer of protection.
Understanding these tricks will help you walk around Cyber City more safely, knowing that your advice is genuine and not a trick from the bad guys. When DNSSEC is your internet superhero, your digital journey becomes much more secure and reliable..
Summary:
- DNS plays a vital role in translating user-friendly domain names into computer-friendly IP addresses.
