is a signature-based antivirus based on cloud antivirus . Its virus database is no longer all stored locally, but it determines whether there are viruses when scanning and interacting with many servers. Cloud antivirus can reduce the frequency of upgrades, reduce the occupation of scanning and killing, and reduce the capacity occupied by local libraries. Next, Kuaiyun will learn about cloud antivirus with everyone.
Regarding the "cloud"
explains in a popular way that the cloud composed of all computers in the network is a shared resource. For example, the Baidu search engine shares all resources on the network, including documents, virus databases, software, etc. In this way, you no longer need to download other people's resources to your own computer before you can use them.
can understand "cloud" as the server/backend, not the side we see every day. It is more virtualized. Most of what we see on our mobile phones and computers every day is the "client" and not the server side.
About cloud computing
Cloud computing proposed by Google is a network application model. In cloud computing, you can edit and store documents without the need for mobile devices such as U disks. As long as you share the URL with others, others You can access the URL through the browser. Avoid data loss caused by hard disk damage in traditional storage.
About cloud storage
Cloud storage based on cloud computing development is based on cloud computing distributed processing, parallel processing, grid computing , and automatically splits the huge computing processing program into many small subroutines through the network, and then uses multiple A large system composed of multiple servers calculates and analyzes the results, and then transmits the results back to the user. With the application of cloud computing technology, users can process tens of millions or even billions of information in seconds, achieving network services as powerful as a "supercomputer".
About cloud security
After the development of cloud computing and cloud storage, "cloud security" was born.
In anti-virus software, there is no way to deal with the increasing number of malicious programs. The threats in the network are being upgraded from computer viruses to malicious programs/Trojan horses. The use of traditional signature databases to identify viruses is no longer applicable. Cloud security technology can identify and kill viruses. It no longer simply relies on the virus database in the local hard disk, but relies on huge network services through real-time collection, analysis, and processing. Treat the entire Internet as a large-scale "antivirus software". The more participants, the higher the security, and the safer the entire Internet. Of course, the emergence of cloud anti-virus has been questioned by many, but there is no doubt that cloud anti-virus will become the latest development trend of anti-virus software. The protection of cloud security is the shared responsibility of users and many IDC service providers.
