Linux Firewalls

Many people might not understand the function of a firewall. The main function of a firewall is to keep your network infrastructure safe from intrusion. Firewalls also have the added benefit of enabling you to limit and monitor the internet usage on your network which means no more employees playing on Facebook for hours.

During the development of the CCS-Africa Linux Firewall Solutions a lot of time has been spent on:

• Developing security policies
• Monitor and Control internet usage
• Detecting and responding to system intrusions
• Creating demilitarized zones

CCS-Africa offers the following Linux Firewall Solutions but can also provide customers with customized firewalls:

Why do you need a firewall ?

• Every business depends heavily on their electronic data and the integrity thereof. Imagine one of the computers on your network are compromised and sends all your confidential data to malicious parties on the internet, or worse everything is deleted and backups corrupted! A firewall prevents intrusions, and can block your internal machines from sending out valuable information.
• When you get to the office, you find that you can’t work on the network at all, you can’t access any network devices such as printers or network files. Where do you start looking for the problem? If you have a firewall, it will log network activity, and you will be able to troubleshoot the problem
• We all know our data networks are not as reliable as we need them to be. In this day and age, being offline can cost thousands of rand per day. A Failover setup on the firewall allows us to use more than one broadband connection, incase one link goes down, you can still function normally
• Access control may be one of the most important reasons. Not only do some employees waste hours on the internet, playing on social networks, etc. But those users are usually to be blamed for virus outbreaks which can cause hours of downtime and even data loss. We can integrate your firewall with your current LDAP/Active Directory and allow access based on the users’s group.

Option 1 – Firewall with Proxy and Ldap authentication. This is the basic solutions but will cater for most small business requirements.

Option 2 - Firewall with Proxy, Ldap authentication and automatic failover between two broadband connections. This firewall solution will cater for companies that can’t afford to lose their connectivity. It enables the automatic failover between two broadband connections for example ADSL and iBurst.

CCS-Africa also offers and additional VPN option(For inter-branch connectivity) on both of the above firewall solutions.
