[squid-users] TCP Flooding attack and DNS Poisioning attack

[squid]

Good day,
Some times when i check my ESET Antivirus LogFile, it shows that some
activities of clients in my network are attacking my network especially
squid port (3128) with TCP Flooding or DNS Poisioning. I check the
internet for there meaning and found out that they are not good activities
on any network.
Is there any configuration option(s) in squid that i can use to drop/block
such TCP Flooding and DNS Poisioning traffic?
Any suggestion?
Regards,
Yomi.
