Basics on Open-source Security

Basics on Open-source Security

Open-source software security is the degree of assurance, or what can otherwise be called as first guarantee that gives developers protection from all possibilities of inherent risks and other potential dangers, arising out of the open-source architecture. In an Open Source technology, it is far easier to inspect the source code and find out precise glitches. This eventually helps in quick unintentional security vulnerabilities as well as preventing the intentional technical problems arising in the source code.

In the current scenario there are various firewall securities available designed to protect the open source technology. Here are few of them:

 IPCop – The effective foolproof firewall security created using Linux netfilter framework. Its primary aim is to offer an easily manageable firewall appliance that is based on the PC hardware.  This firewall security is based on Linux kernel 2.6.32. It makes access to web pages by entering a unique password. The IPCop v. 2.0 now incorporates several changes including there is a New installer that helps in quick installation to flash or hard drives. This latest version also allows programmers to choose interface cards and ensure they are assigned to particular networks.

Smoothwall – This smart open source firewall protection is designed to run efficiently on older, cheaper hardware. The firewall protection is operable on any Pentium class CPU, with the recommendation for 128 MB RAM. This firewall security is effective with support for Simple to use Quality-of-Service (QoS), UpnP support, Outbound filtering, as well as supports the LAN, DMZ, and Wireless networks, besides external networks.

IPFire – This open source security firewall is Linux based and provides the corporate level protection.  The firewall makes the use of  Packet Inspection (SPI) firewall, built on top of netfilter.

pfSense- It is a superb open source firewall/router distribution, which works on FreeBSD with a fork on the m0n0wall project. This firewall protection has the advantage of incorporating almost all the functionality of m0n0wall, and this includes VPNs, traffic shaping, NAT/port forwarding etc.

However, there are also potential drawbacks of open source security, and it is very essential that you are aware of those drawbacks from every respect. One of the biggest threats is that all developers, programmers and even the attackers have open access to the course code. Therefore, manipulation and changes can be made. Firewall security cannot be the sure shot success when it comes to open-source security. Multiplicity of things has to be taken into consideration.
