Outline
Based application services, by definition, a company based on enterprise services in the enterprise plays an important role. DNS, FTP, Mail, etc. can be seen as the basis for software applications. If the site can not login, can not properly send and receive e-mail, information system is not stable enough, will bring the number of losses? Even catastrophic consequences!
Application services based on the importance of the enterprise
For example, we get DNS services, as the network's infrastructure, almost all network applications, must rely on URL query DNS system as action guidelines.
Even if the Web server intact, if the DNS is not working properly, the firewall system also fulfill their duties, related back-end application servers and database systems are functioning properly, that is, in the period of time because they can not get this web site, will result in an e-mail can not pass, you want to use the domain name to connect to a web page, we will be unable to identify the network address, so that on-line failure.
Past experiences, the majority of attacks target mainly concentrated in the control network routing devices (routers, firewalls, etc.) and various application servers (Web, e-mail, etc.). Therefore, most of the existing network security protection, usually concentrated in the routing device and application server itself. However, previous attacks of other sites the biggest difference was the object of attack is the DNS server instead of WEB server itself. This new type of network attack, so we had to re-examine the importance of basic applications.
Internal Web site or the normal operation of the system, application services based on the merits of some of the key parameters for system administrators, site administrators locate or analyze problems, is the most important.
DNS resolution time for service
DNS service for computer analysis and buffer the domain name system, if there are problems, it will affect normal access to the network, the normal resolution of the time the most important.
Standard DNS services, as shown below:
System on a regular basis to resolve the specified domain, and can resolve IP addresses to check out, which effectively ensured the normal DNS services, including domain name resolution response time of real-time view can be used to judge the DNS service is working correctly.
The stability and speed of FTP service
As File Transfer Protocol (FTP) service, easy to upload and download the company used to transfer important files over the network to manage the server directory. Once the problems will affect the normal use of the usual company information. Stability and speed, is the most concerned about.
Standard FTP service, the following chart:
One can view real-time FTP upload and download speed, easy to determine the current status of FTP, a reasonable allocation of FTP upload and download rate.
Mail services to send and receive service status
Standard Mail service, as shown below:
Real-time to view the Mail server, SMTP, and POP3 service status of the service, send and receive mail services at any time about whether it is normal.
Summary
Basic services through the services of each standard to achieve meticulous management, real management, management guru Peter Drucker has said - "can not be measured can not be managed", with the threshold of these standardized indicators, it is reasonable use of IT resources, improve efficiency, allow us to better manage services-based applications.
