Norton BloodHound heuristic engine
BloodHound is Symantec's exclusive heuristic detection technology. Like many heuristic engines, it detects viruses based on suspicious behavior. BloodHound will create a virtual safe environment so that the virus can show its bad intentions without affecting the stability of its own computer operation.
Comprehensive SONAR behavioral detection/defense technology
Inspiration only runs on virtual hosts. If a virus Trojan unfortunately enters a physical host, you have to use "behavioral defense technology"; behavior Defense will analyze the behavior of suspicious programs and block them in advance. Norton's famous SONAR is undoubtedly the most mature among them. Intuitively speaking, SONAR is a behavioral detection/defense technology that can prevent malicious program code from intruding before creating virus definition files and spyware detection definition files. These emerging and unknown malicious codes will attack and damage through Trojan horses, worms, mass mail viruses, spyware or downloader viruses. When many products only use a limited set of heuristics, SONAR can greatly improve their protection capabilities through extensive and heterogeneous application behavior data, and significantly minimize the false positive rate. Specifically, SONAR technology is different from Kabbah's simple active defense technology. It pays more attention to path defense (Norton focuses on path defense, mainly through various defense technologies that do not rely on virus databases to block various virus infection paths, such as vulnerability defense. , browser defense). SONAR collects and integrates information based on a series of engines in the product, such as firewalls, anti-virus engines, intrusion prevention engines (IPS), browser defense engines (Browser Defender), etc. All this information is then used by the classifier to improve performance. This is very different from the technology of other manufacturers. Many other security vendors don't have such a vast amount of information to make good classifiers.
Global Intelligent Cloud Protection Technology
Like many mainstream anti-virus software, Norton also has its own global intelligent cloud protection technology. In addition to virus definitions of known threats, "Norton Global Intelligent Cloud Protection" can also use the security and data of "Norton Community Defense" to identify new threats and their sources, thereby providing users with additional security protection. In addition, unknown and suspicious files intercepted by SONAR technology will also be automatically uploaded to "Norton Community Defense" for analysis.
Norton Insight
Norton Insight, a new technology added by Norton in 2009, is simply a whitelist (but the list rules are not stored in the software, but through Simon Tieke has another platform that is updated at any time). The principle is to only scan untrusted files or websites, and skip well-known or safe files and websites. This technology can greatly speed up the scanning and reduce errors. Judgment rate. With the addition of these proactive innovative technologies, Norton seems to be more in line with the definition of anti-virus software than anti-virus software. Even though Norton's own manual scanning detection rate is not high, with these technologies, viruses can still be kept out, rather than passive antivirus after poisoning.
