Firewall PolicyFirewall policy is generally divided into two kinds, called "Pass" strategy, a "blocking" strategy, a strategy, the default door is closed, you must define who can enter. Blocking strategy is that the door is open, but you must have identity authentication, otherwise you cannot enter. So we want to define, let come in, let go out, so pass, is to all pass, and plugging, then is to choose. When we define a strategy, we define several functions, including the ability to define a poli

So far, only the access control rules have been discussed, which constitute the DACL of the object. DACLs can be arbitrarily changed by the owner of the object, or by any person whose owner has given them permission to change the DACL. The security descriptor for the object contains another list of rules, called the system access control List,sacl, which controls which type of auditing the system performs o

What is a sorting rule? The sorting rule specifies the bit mode for each character. It also specifies rules for sorting and comparing characters. Ordering Rules have the following features: ◆ language ◆ case sensitive ◆ Stress Sensitive ◆ distinguish Kana to understand the ordering rules currently used by the server, you can run the sp_helpsort system process in

Apriori algorithm is a basic algorithm of big data in association rules. The association rule Mining algorithm was proposed by Rakesh Agrawal and Ramakrishnan Srikant two PhD in 1994. The purpose of association rules is to find out the relationship between items and items in a data set, also known as shopping blue analysis, because "Shopping blue analysis" aptly expresses a subset that applies to the algori

Recently in the re-learning of HTML knowledge, is a re-understanding of HTML it! Do not underestimate this thing, all the pages can be based on it! The following is a detailed summary of the HTML tag nesting rules, I hope to help you.There are many XHTML tags: div, ul, Li, DL, DT, DD, H1~H6, p, a, Addressa, span, strong ... When we use these tags to build the page structure, it is possible to embed them infinitely, but, nested also need to have a cert

code. What I'm going to say is that unit tests have to be done. This is the most basic principle of programming. This is the least overlooked of all the above rules. If your colleagues can create and test unit tests for your code, this is the best thing to do. But if you don't do these things for you, then you have to do it yourself. When you create your unit test plan, follow these rules: First, write the
