Today most of the internet users faces different types of cyber threats like phishing websites, DNS spoofing attacks, malicious redirects, and also unwanted tracking activities. However users make the use of blacklists and signature based detection in order to block the websites but this method is not effective for newly created malicious websites. So to solve this issue, we decided to design and developed the Agentless Unified Defense System (AUDS). This system gives real time protection without any need of extra software. It works directly inside our browser. When the site looks unsafe, then it blocks the access. Also when the site appears to be suspicious, it opens in a separate Disposal Window to keep the browser safe. In this way, AUDS provides simple web security.
