网络安全中客户端过滤器和服务器过滤器之间的区别

过滤器用于检查用户输入的输入是否遵循可接受的标准。过滤器可在浏览器(客户端过滤)或服务器(服务器端过滤)中使用，以验证用户在Web应用程序中提供的输入。

1.服务器端过滤器：
这些是服务器中存在的筛选器检查的类型。当用户键入输入时，该输入将转发到服务器以进行验证。如果用户输入的数据有效，则接受输入，否则将根据输入引发错误。

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，输入将由客户端过滤器进行验证。如果用户输入的数据有效，则接受输入，否则将根据用户键入的错误输入引发错误。

客户端过滤器和服务器端过滤器在网络安全方面的区别：

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’s.	Provide better security to data’s.
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.
