Which business firm or individual can afford to
leave their networks unsecure and open to all kinds of attacks? Well in my view
no one. But, still most of the firms and people either don’t prioritize securing
their networks or don’t have resources to do it.
Whatever the case is leaving the network safety at
bay is going to cost you even more than you expect as a business, institute or
an individual can be deprived of its most important and sensitive data by the
hackers, breaches or cyber-attacks in no time.
Don’t act carelessly:-
You don’t leave your front door
open in the night and expect that no burglar will invade your house. Don’t you? Same is the case with networks,
leaving them unsecure and expecting that no extraction, theft or sweeping of
manipulation of data will happen is like living in the heaven of goofs.
Do it now:-
Turn to firewall migration before it’s
too late. Be proactive; secure the network and data so it would be now or
never. What you need to do after the installation of a packet filter to secure
the network.
Monitoring:-
As we all are aware of the fact
that the packet data is the first line of defense against any outside threat.
And at this moment the altering of the configuration of the packet filter by unauthorized
people and accessing it is not acceptable at all.
Change of rules:-
So
it becomes extremely important to apply two security controls which are necessary
- User permission control
- Network access security
The
application of these security parameters make sure that no unauthorized access
is granted and only those can access the firewall that are authorized to access
it change the rules. The activities made during the change of packet filter
rules must be logged in the audit trails.
So
if there is a need audit and compliance they are easily accessible.
Configuration management:-
It must be made sure that the
techniques of network configuration management are adopted for the vigilant
monitoring of packet filter’s configuration changes actively and also prompt
alerts are issued in case of configuration changes that are unwarranted.
Also user profiles are necessary
and they must be given different access levels to the IT department who are
taking care of all the activities and are in charge of firewall management.
And most importantly it must be
made sure that all the logs whether they it is incoming traffic or outgoing are
strictly monitored. It must be done to be aware of any unauthorized attempt of
breaking in on the packet filter not only from outside but from the inside of
the network too.
