Do you know your most of vulnerabilities can be wiped off
from your PC if you control the outgoing traffic from your local machine? Read
whole article recommended specially for virus infected computer and system
administrators.
Hi beloved audiences,
welcome to Intelligent computing. Today I’m going to tell you how you can make
your computer more and more secure by controlling your outgoing traffic.
All computers deals
with mainly 3 type of connection way, incoming, outgoing and local loops. One can
interrupt your computing while attacking from outside network via open port. but
this is not the only solution, do you know outgoing traffic can do even more
harm and no one else knows that their computer has become dangerous.
Outgoing port helps attacker to gain your PC
To understand all
this you need to know how a usual attacker does attack.
First of all
Attacker wish to compromise your PC by sending the malware in it, via USB, via
Attachment, via web page Script stored in cookies.
After that Malware
resides in your PC and keep collecting your Data, Passwords, keystrokes and
other confidential information.
Last task of these
malware is to send all these information to the attacker, that is home from
where malware is originated.
For this reason
Malware needs and keep looking for extra port and unidentified port in your
computer.
Once they’ve
discovered, all your collected data is sent to the hacker and here how you can
be affected.
This makes clear
that even if your PC is been compromised with malware, your Information can
still be protected. All your computer needs only few registered port for real
and known communications. Its almost 1-1000 port among 65000 ports. Some well
known ports are
HTTP 80
HTTPS 443
DNS 53
Malware needs
unidentified ports which remains open in your Firewall settings.
Another reason for
blocking outgoing traffic
Programs which
makes connection via outgoing connections
There are lots of applications
which make outgoing connection to talk to servers like locally installed chat
application, or updates of application. Malware sometime tricks these
applications port and path to communicate behalf of these applications and
sends information to attacker.
How to block outgoing traffic in best manner
Blocking all out
going port initially except 80 and 443 is best practice. But lots of
applications which really need to communicate using outgoing port for one or
another reason that we need.
So you can make
exception or get Windows Firewall in strict manner.
You can look up Howto setup advance firewall in Windows to make exceptions and make your PC more
and more secure.
Bottom line
Firewall is rule to
allow or block specific port/IP/Socket. Making proper plan as per the home
network, business network or other network and preparing setup of these
connection can help user to better protect your PC. Share this post to your network
