The technologies are getting higher and higher as time pass by and it seems nowadays if you are not online, you don’t be present. But in every good things happened there’s always a bad thing twin of it, for example in the computer if there are no bad guys who creates viruses, spyware, spams and other malicious programs we can surely use our computer safe but sad to say it didn’t happen. What security protection measures have you taken to make sure the valuable data saved on your computer’s hard drive are safe? There are quite a lot of safeties measures which you should do at all time to apply to your computer in order to make your saved data secure and protected.

By using Linux you are lot safer compare from other operating system, Linux is an operating system that is by far more secure than Windows, security issues still arise every time and in order for you to be completely peaceful and safe, you have to save your Linux computer from harm with a firewall. Although most businesses and companies focus on the Windows platform and thus, firewalls are mostly targeted for the Windows operating system, don’t worry; there are a lot of firewalls available for Linux and most of them become visible to do a great job. Linux uses iptables filter to give stronger defence and protection. That software included in basic Linux packages so we can accurately resolve the security issues by means of checking the incoming traffic with this program also we can define the criteria for each port, services so we can define our own strict rules for our incoming traffic.

A firewall is an enormous beginning even if you’re using any operating system you can still use firewalls to protect your computer (even not Linux). Firewalls can be both hardware and software based. There are a lot of different firewall vendors some of the bigger names are Cisco, Symantec, and Checkpoint. The complicated part is configuring the firewall. This is where many intruders bypass security, because the firewall is poorly configured. Firewalls are essential for computers if we connect to internet. There are different kinds of methods on how the firewalls work and check the incoming information. At the same time the firewalls let the outgoing ports open. It gives security for our computer and protects it from the system mistakes as well. For personal computers it can be sufficient and helpful but for networks maybe not.

To ensure complete data security, it is required to make regular data backup. You should always backup your most important data, without which your business can not proceed
