PHP and SQL injection attacks [3]. These days are too busy to continue the serialization. haha, we will try to end in half a month. As mentioned above, the insecure input filtering function provided by the database is not available in all databases. I am too busy these days. I will continue to attach the service and try to end in half a month.
As mentioned above
The function used to prevent SQL injection attacks can be used directly, but we will not use it, but we need to enhance our safety awareness.

The purpose of this article is to illustrate the practice that asp.net developers should always adhere to in order to maintain a reasonable level of safety standards. This is the most important aspect of security: stay vigilant and never completely relax, making it increasingly difficult for the bad guys to launch a hacker attack.

Audits play an important role in reducing the risk of denial, and also play a key role in identifying other types of attacks. For example, if the statistics in your audit record indicate that your service has unusual usage, you may not be aware that your s

Even if you think that all requests must come from a particular application, you should assume that the incoming data is invalid before you prove it. The fact is that requests for XML WEB services can come from anywhere. If you make assumptions about your data, you should assume that the data might come from a malicious user.
