با اجازه استارتر
با نصب و کانفیگ csf و همچنین نصب و کانفیگ لایت اسپید میتونید جلوی این مورد رو بگیرید برای مثال در csf با کم کردم مقادیر
CT_LIMIT البته تا 350 کافیه ولی در زمان حمله شدید حتی 50 و 20 هم توصیه میشود و مقدار CT_INTERVAL به 10
و در مورد لایت اسپید هم با تنظیم مقادیر زیر
Connection Timeout (secs) توضیحات
Max Request URL Length (bytes)Connection Timeout
Specifies the maximum allowed connection idle time during processing one request. The connection will be closed whenever it is idle, no i/o activity, for this period of time.
Syntax: Integer number
Tip(s):
- [Security] Set it to as low as you can to help recover dead connections during potential DoS attack.
توضیحات
Max Request Header Size (bytes)Specifies the maximum size of a request URL. URL is the full text address used to access a server resource including query string. 8192 bytes is the hard limit.
Syntax: Integer number
Tip(s):
- [Security & Performance] Set it low and reasonable to reduce memory usage and help identify bogus requests and DoS attacks.
- 2-3K is big enough for most web sites unless HTTP GET method is used with large query string instead of POST.
Max Request Body Size (bytes)
