ESD is the release of static electricity, which can cause various damage to precision semiconductor chips, such as penetrating the thin insulating layer inside the component, and damaging MOSFET and the gate of CMOS element; The trigger is locked in the CMOS device, causing a short circuit of the PN junction of the reverse offset and forward offset, and melting the welding wire or the aluminum wire inside the active device.
In the computer industry, ESD is a frequent occurrence of invisible kil

Below through two aspects to introduce JS code to prevent SQL injection method, very simple and practical, interested friends under the reference bar!
1.URL address anti-injection:
Filter URL illegal SQL character
var surl=location.search.tolowercase ();
var squery=surl.substring (surl.indexof ("=") +1);
Re=/select|update|delete|truncate|join|union|exec|insert|drop|count| ' | "|;| >|
2. Input text box anti-injection:

Use passwords for all MySQL users. The client program does not need to know the identity of the person who is running it. For client/server applications, users can specify the user name of the client program. For example, if Other_user does not have a password, anyone can simply use Mysql-u other_user db_name impersonate someone else to invoke the MySQL program to connect, for MySQL attacks. If all users have a password, it is much more difficult to connect using another user's account.

Trojan is the use of IE to spread the vulnerability, we take the ice Fox prodigal son of the Web Trojan (with "Ice Fox prodigal son Trojan Horse" made by the Web Trojan), the Web page can bypass the security settings of IE, when users connect to the page, It can download a Trojan horse and run (install) the Trojan in the background without the knowledge of ordinary users. Therefore, often to the Microsoft website to download and install the latest security patches is a more effective way to
Because Nginx does not support. htaccess, it is not feasible to prevent it directly from this aspect, we have to fix it by modifying the configuration file.First, we find the need for anti-theft chain of the domain name conf file, path:/usr/local/nginx/conf/vhost/, such as guance.com.conf. First back up the original file, and then find the following section:
Location ~. *\. (gif|jpg|jpeg|png|bmp|swf) $
{
expires 30d;
}
Modify it to:
HH:MM:SS GMT
Cache-control:no-cache, Must-revalidate
Pragma:no-cache
The first line tells the Mini browser that the page has expired for some time. The second line tells the browser when the page was last modified. DD should be replaced by day date, month YY HH MM SS, and so on. The third and fourth lines have the same effect. Tells the browser that the page is not cache (the third line applies to HTTP 1.1, and line fourth applies to HTTP 1.0).
The following is an example of PHP:

There may be imperfections or even incorrect places, you are welcome to point out the progress together.
Prevent IIS from caching static files (png,js,html, etc.) Background:IIS in order to improve performance, by default, the static file js,html,gif,png, such as internal caching, this cache is in the server IIS process memory. By doing so, IIS can greatly improve the access performance of static files, and the cache is updated as long as the static files are updated in the normal way. However, if there are many newer static files, there is a risk that t
appended with the frame head and frame end of the data link, and the packet is put into frame. Finally, the physical layer is converted to bits-per-unit data. Therefore, the IP address is the network layer used to identify the logical address of different locations, its length is 32 bits, and at the data link layer is the MAC (media access control) address to identify the location of the network node, its length is 48 bits, it is also the physical address of the device.
