The more our society becomes dependent on computers, the higher the demand for dependable software is. Some time ago, fault tolerance was the exclusive concern of highly specialized organizations. Unfortunately, the inherent complexity of our world makes fault-tolerant computing quite difficult, as it involved intricate algorithms. In spite of our strenuous efforts and attempts, we cannot say that we now have 100% reliable software. But the probability of failure has been reduced considerably, reaching what is now called ?an acceptable level?.



Fault tolerance refers to a system's ability of performing its functions correctly even when internal faults occur. Fault tolerance serves the purpose of making a system more dependable. Failures occur when there is a deviation from the specified behavior of an actual running system. Errors are considered to be the cause of failures, and they are a result of faults in the system. Fault tolerance procedures generally include error detection, damage confinement, error recovery, as well as fault treatment.

Transparency is another important issue in the process of using the Internet with business purposes. As opposed to private networks, the Internet provides rather inexpensive connectivity. However, using the Internet comes with a series of vulnerabilities such as security holes or attacks from intruders. In other words, the Internet is a zone with no trust, as opposed to internal networks, which are high-trust zones. Companies are faced with the need of having a firewall to separate the outside world from their internal network. Controlling traffic between computer networks with no trust and high trust is the basic task of a firewall. A high performance firewall that separates authorized users from unwelcome intruders is FireSafe. With FireSafe companies no longer have to worry about IP security.

The configuration of firewalls is such that these IT security devices can deny, permit or proxy data connections, which are set and configured according to the specific security policy of each organization. The basis of a firewall can be either software and/or software. The high quality components of FireSafe do not include a hard disk or any other similar moving parts.

FireSafe comes with easy setup and configuration, and, unlike other firewall products, the sense of security it creates is totally genuine. This product provides flexibility, as the filtering approach it employs is rules-based, but at the same time it ensures totally controlled security. The only requirements of the FireSafe configuring process are secure access to this product and IP connectivity.

Going back to its access control feature, companies should know that there are several ways in which FireSafe can control access to your internal system. These include address- based, time-based, and authenticated. It also has the ability of filtering or blocking specified URL, and of logging access attempts, either successful or unsuccessful.

As the producers of FireSafe are market leaders in IP load balancing, it goes without saying that this product s highly performing and reliable.
