网络安全中客户端过滤器和服务器端过滤器的区别

过滤器用于检查用户输入的输入是否符合公认的标准。过滤器用于浏览器(客户端过滤)或服务器(服务器端过滤)以验证用户在 Web 应用程序中给出的输入。

1. 服务器端过滤器：
这些是服务器中存在的过滤器检查类型。当用户键入输入时，输入被转发到服务器进行验证。如果用户输入的数据有效，则接受输入，否则根据输入抛出错误。

2.客户端过滤器：
这些是浏览器本身中存在的过滤器检查类型。当用户键入输入时，输入由客户端过滤器验证。如果用户输入的数据有效，则接受输入，否则根据用户输入的错误输入抛出错误。

网络安全中客户端过滤器和服务器端过滤器之间的区别：

CLIENT SIDE FILTERS	SERVER SIDE FILTERS
The filters are present in client side or browser side.	The filters are present in server side.
Client side filters are easy to bypass or tamper.	Server side filters are difficult to tamper or bypass.
No load to the server as the browser is performing the input validation checks.	Server recourses are used as the input validation checks are performed in the server itself.
Code is written using client side languages like html, java.	Code is written using server side languages like php, c#.
Input is first validated by browser and is then forwarded to the server.	Input is forwarded to the server as it is (without the intervention of browsers).
Don’t provide much security to data.	Provide better security to data.
Response from client side filters are faster since they reside in the user’s browser itself.	Response from server side filters are slower since filter checks are present in server and they are sent back to user’s browser.
