in the options statement: Options { Allow-query {210.10.0.0/8; 211.10.0.0/8 ;}; }; (4) separated DNS (split DNS) The split DNS technology is used to divide the DNS system into two parts: Internal and External. The external DNS system is located in the public service area and is responsible for normal external resolution; the internal DNS system is responsible for parsing hosts on the internal network. When you want to query domain names on the Internet, the query task is forwarded to the extern

directly connected REMOTE_ADDR.But the security risk is that the x_forwarded_for information is a field in the HTTP header that can be modified (forged) to any string. Suppose a business scenario is: The user's IP into the database, if first obtained the user forged IP string, injected SQL query statement, resulting in SQL Inject vulnerability.So either get remote_addr directly, or filter the http_x_forwarded_for and so on (for example, filter by for

To continue the discussion on PHP application security, pay attention to the following aspects: 1. Filter SQL injection attacksYou can use PHP built-in functions such as addslashes to directly provide functions for ease of use.Function verifyinput ($ input){ If (! Get_magic_quotes_gpc ()){// Magic_quotes_gpc is on by default and will automatically escape characters such '.$ Input = addslashes ($ input );}

When an Office application opens an Office document, it starts with a checksum, primarily verifying the validity and integrity of the document. When you arbitrarily change the suffix of an EXE document to docx, opening the file will definitely invalidate the file. For an Open XML document, if you want to verify it, there are several aspects: Q is not a zip compression package Q Does the necessary part exist Q is the relationship complete Q Does t
