On Internet which was compared by many with the Wild West, it is critical that your services get top protection from the agressive DoS/DDoS attacks targeting them. While a DoS is generally easy to detect and to block, the latter is a more sophisticated and more aggressive type. A DDoS attack is carried by hundreds or thousands of computer owned by unsavvy users who have no idea that their computer is infected by a virus that’s invisibly making their PC a part of a massive group of computers under the control of a cyber criminal.
A DDoS attack typically means “bombarding” a certain target simoultaneously from hundreds or thousands of sources with mailitious traffic. An unprotected server won’t cope with that traffic and will become unavailable within seconds. Some of these attacks can go on for days. Just imagine the impact on your business if your site would be offline for days in a row.
The smart firewalls constantly analyze the inbound traffic and they react immediately in case of unusual behaviour (traffic spikes) by determining the type of attack and blocking it. The malitious traffic is discarded while the legit traffic passes unrestricted. This way your services remain up and running during the attack.
In November 2013 NAV Communications deployed on of the best DoS/DDoS attack mitigating solutions on the market that uses an advanced protection technique called Traffic Scrubbing. Due to security concerns we are not able to disclose the details of the setup, detection rules and mitigation actions.
