Internet gateway is an interface with dedicated Internet connection. It provides a point of connection with the Internet, no matter whether the interface has any connection with the internal departmental or company network. A secure Internet gateway can tighten the control and establish a more cost-effective and secure operation environment.
Because of the openness of the Internet and the rapid growth of complex network services and applications, the lack of security protection on the gateway may leave the internal network vulnerable to attacks. Hence, an Internet gateway should be properly configured with appropriate security measures to protect it from attacks.
インターネットの解放性と複合ネットワークサービス・アプリケーションの急速な成長のおかげで、ゲートウェイのセキュリティ防御の欠損は攻撃されやすい社内ネットワークになったままかもしれません。このゆえに、インターネットゲートウェイは外部攻撃から守られるために適切な方法できちんと設計されるべきです。
Great!
