Securing data is
essential as there are lots of threats which can affect the integrity of data.
Apart from protecting the information, you also have to provide safety to
applications as well as other services. One of the most common types of threat
that you will come across is DoS (Denial of Service). It easily penetrates in
to the network or the system so the best way is to block it. Establishing
connection with a port can help you to identify whether the packet that you
have received is genuine or not. Packet
filtering is a great option but you can even employ top security methods for
your OS.
Unauthorized access is
another very popular issue that is faced by network administrators. There are
different kinds of unauthorized access which include data diddling, data
destruction, etc. The main aim is to get the access of any system so that it
can be used for extracting useful information or also to change the details. Hence
to combat with such problems it is necessary that two factor authentication or
three factor authentications is done. Antivirus program, firewalls, intrusion
prevention etc are some methods which can be followed to keep away from such
threats that can harm your systems and devices.
Security management is
therefore a concept which plays crucial role.
Every business, application, school, government organization etc all
needs security policies which can help them in securing the data and removing
the flaws. Mere installing an antivirus program will not be sufficient but
regular updating can be of immense help. Even firewalls are quite effective.
You have firewalls for application gateways, packet filtering, hybrid systems
etc. So according to your needs you can find out the most suitable firewall
that will give efficient results. Not only the firewalls but even modems can be
hazardous if you allow the incoming calls.
The modems that you use
should have strong password and any unauthorized user should be checked. Even
crypto capable routers can prove helpful as it easily identifies the unknown
resource and does not allow it to reach to your systems. Another every
effective approach which you can pursue is to use VPN (Virtual Private
Networks). This will provide easy communication with other networks that have
been connected through a private leased line. According to your requirements
the two parties can customize the functions and avail enhanced security. Thus
by employing the correct strategy you will be able to achieve authentication,
confidentiality and integrity all.
