It is a very good day, today. I feel much better and the feeling is that RECOVERED. Even I already used VPN for almost two years, but I didn’t fully understand it. I studied VPN at morning and found it is so easy, later on I read IAS and RADIUS. All the three issues are easy to be controlled. After that, I started a new chapter, and then I read thousands of the word “security”. Security is the most important thing not only for the computer system but also for the social system. Especially for our office, the word security is always an issue; once I joined the office and got the current job I know what the security means.
The security issues I read this afternoon include:
- Network security protocols about authentication, authorization, confidentiality, integrity and nonrepudiation
- Security templates section talks where the default templates are, what the templates covers
- The principle of least privilege means that no employee and no user of information system, includes system administrators and IT workers, has more privileges or access to information and resources than they need to do their job.
- Security Templates console to create new folder for copying/modifying templates
- Security Configuration and Analysis console to apply and compare templates
Also, here is some free document from Microsoft cover the security:
