Preface: I am a student studying network engineering at Peking University # training institutions. Because I am more interested in routing exchange technology, I took a ccna test during my school years, as a quasi-It practitioner, I hope that I can maintain my learning spirit and learn more from my predecessors. The following is a simple experiment by myself, which combines ACL and SSH applications. 1.Experiment topology and experiment requirements,

The friends who read this article need to have a preliminary understanding of the Windows access control model, understand the token (access token), ACLs (Access control list), DACL (Select access Control list), ACE (Access control list items), and the relationship between the noun meanings associated with the access control model, Of course, I will also briefly in the text of the Science of ACM. The main purpose of this article is to write a win under the local right of the thing, involving th

, session. So basically the SID can be understood as a user name, a group name, a session name. It's just that they are safely certified and not duplicated, which is safe and reliable. If we mention Zhang San this user's SID, then we can be understood as "Zhang San (true)". Security descriptors (Safety descriptor) MSDN says the security descriptor contains security information that describes a securable object. In fact, this sentence is very right, but it is probably on the. Let'

Defining the log parameters in the ACL in cisco is easy to use. If the log parameters are added, all entries that comply with the rules will send a log message. If they are the same data packets, logs will be sent at a certain interval. It is impossible for each log to be sent. The log level is information,However, if I use the operation defined on user maual of cisco 3750 to send packets that comply with the rules, the log information will never be s
