Avoid disruption to your business even during an attack
Denial of Service (DoS) and Distributed Denial of Service (DDoS) attacks have been around for nearly a decade but they still rank high on the list of most common threats.
DoS and DDoS come in many shapes and forms but they all aim at one thing: interrupting service by overloading the network, its system resources or application resources. Downtime means lost revenue, productivity and reputation damage to the brand.
Avoid disruption to your business even during an attack
Increased performance in normal operations thanks to a healthier network
Since DoS and DDoS attacks come in so many variations, it requires a combination of different features to provide overall protection. No matter what type of Dos/DDoS attack or the nature or scale of your business, Clavister has a solution. By leveraging the powerful DoS and DDoS mitigation features inside the Clavister Next Generation Firewall, you can ensure that your organization can withstand these attacks with as little disruption possible.
Managing an attack is partly about protecting your public-facing services as well as maintaining operations for the internal networks. Clavister has features and capabilities designed to address both aspects in an efficient manner.
Intrusion Detection and Prevention is an integrated feature in Clavister's Next Generation Firewalls that can identify both known and unknown attacks by combining several techniques, including signatures. Clavister’s IDP functionality looks both for known attacks and unknown attacks that attempt to exploit vulnerabilities in protocols or applications protected by the Clavister Next Generation Firewalls.
Rate Limiting is one of the key features in efficient DoS and DDoS protection. Using this feature as a baseline for normal usage can be established, making it easy to detect and block abnormal amounts of concurrent connections or the connection setup rate from a single user or network segment. By fine-tuning this relatively simple feature, it becomes exponentially more difficult for hackers to create overload attacks against the servers protected by Clavister Next Generation Firewalls.
Using the Traffic Shaping feature, it's possible to ensure that no single user or single network segment can overload—e.g a web service—by sending or requesting abnormal amounts of data and creating an overload situation that impacts the service for legit users.
Thanks to this feature it forces the hackers to utilize much bigger networks (of so called Zombies) to acheive the same stress on the servers protected by a Clavister Next Generation Firewall, the effect is a more robust and resillient network compared to one without this protection mechanism.
Many DoS and DDoS attacks originate from specific countries where the majority of the so called Zombies or Bots are located.
By creating temporary, or permanent, policies based on the geographical source of the traffic it's possible to greatly minimize the impact of an attack. If the majority of the malicious traffic is coming from a few countries, you simply block or traffic shape this traffic at the border of the network, thereby freeing up capacity for legit users who originate from other geographical locations.
The Clavister Next Generation Firewall has a built-in capability for distributing traffic across multiple servers in a server farm. Instead of being limited to the capacity of a single server, Clavister creates a cluster of multiple servers to share the traffic load, multiplying the capacity immensely. With more performance and capacity comes more difficulty for hackers to achieve any negative impact on the network service.
WAN Load Balancing makes it possible to utilize the capacity from multiple internet links to reduce single-points of failures in an overload attack situation.
This is also an excellent strategy to use so that internal network segments operations can be maintained, even during an overload attack on your public facing services such as websites. Even if your primary link is completely saturated by malicious traffic, your internal users can continue working and having access to critical resources on the internet using a different WAN link.
One of the benefits of using a properly configured Clavister Next Generation Firewall with the various DDoS protection capabilities activated is that the traffic will flow smoother in normal operations. Quicker response-times, fewer "out-of-service" events and overall better performance is often reported by customers who have fine-tuned their network to withstand DoS attacks.
By reducing the risk of critical services becoming unavailable during a DoS attack the risk of embarrassment and lost revenue is reduced.
By utilizing the built-in features and capabilities already included in the Clavister Next Generation Firewalls instead of adding single-purpose appliances, the Total Cost of Ownership is drastically reduced. Not only is there a far lower capital investment, but there's also additional savings in administration with fewer devices deployed, operated and maintained.
With the Clavister DDoS Protection capabilities, it's possible to avoid an attack towards your public facing services that bring the entire internal network to a halt. This ensures that the organization can continue and maintain most of its services for employees and other internal users even during a massive attack.
With a more resilient protection against DDoS attacks and lowered impact for the overall operation, there is less incentive for hackers to exploit the opportunity where the disturbance / cost related to an attack motivates paying out a ransom fee. With Clavister, you won't be an easy target.
