NAT 和 VPN 的重要性 防火牆也執行基本的網路層級功能,例如網路位址轉換 (NAT)和虛擬私人網路 (VPN)。網路位址轉換將可能位於 RFC 1918 中定義的「私人位址範圍」內的內部用戶端或伺服器 IP 位址隱藏或轉換為公用 IP 位址。隱藏受保護裝置的位址可以保留有限數量的 IPv4 位址,並且可以防禦網路偵察,因為 IP 位...
For instance, in China, the government has fortified its “GreatFirewall” to block websites and VPNs. Notwithstanding, some internet users use certain Virtual Private Network to get through these issues. Another country whose measure to ban the use of VPNs have failed is Russia because the V...
This document uses Huawei USG series firewall products as an example to introduce the basis of SSL VPN. There may be differences in the implementation of different products and versions. Please refer to the specific version of the product documentation. FW is short for firewall. In this documen...
More firewall-friendly Traditional VPN protocols end up being slower, as they use protocols such as TCP that contain error-correcting features. Our VPN Vault protocol runs over TCP using TLS (Transport Layer Security), a cryptographic protocol that mimics most Internet traffic. This allows our VPN...
Learn what a firewall is, why it is important, how it works, and firewall best practices. Learn how a firewall can ensure the data is harmless and prevent data from being stolen or compromised.
A firewall is a necessary safeguard for any online network. But while every computer comes with some basic firewall protections, there are still vulnerabilities that can be exploited without an advanced firewall shield. Learn what a firewall is, how it works, and how an industry-leading cyber...
What is AWS Network Firewall? 隨著雲端採用率的增加,雲端資安的重要性也隨之成長。在雲端共享責任模型下,雲端客戶與雲端供應商共同承擔保護其基於雲端的資源的責任。 由於在雲端部署傳統安全解決方案存在困難,許多雲端服務供應商提供內建解決方案,例如AWS Security Groups來幫助客戶履行安全責任。Amazon Web Services ...
Using a VPN (virtual private network) is one way you can protect your privacy online and keep your information safe from hackers, internet service providers, and other 3rd parties. A VPN allows user to securely browse and access personal data through public networks. Much like a firewall prote...
2. Routing your traffic through VPN servers Next, your data is transferred via a remote server instead of going to the destination directly. VPN hides your real IP address and physical location—anyone attempting to trace back your internet traffic will only be able to get as far as the new...
There are three reasons to deploy a firewall in the network: access control, NAT and VPN. Access control is where policies are created to block or permit traffic based on IP address, port and protocol. NAT, or network address translation, is the act of converting one IP address to another...
