So, the application must be fully protected against threats intended to directly or indirectly compromise application reliability to be truly mission critical in nature. How an application mitigates those attack vectors, such as SlowLoris will impact the overall reliability. For example, successful Denial-Of-Service (DDoS) attacks are known to have a catastrophic impact on availability and performance. Given that the primary focus of a mission-critical design is to maximize reliability so that the application remains performant and available, the security considerations and recommendations applied within this design area will focus on mitigating threats with the capacity to impact availability and hinder overall reliability. To protect an organization from known attacks and prepare for potential zero-day attacks, multilayered DDoS protection, such as FortiDDoS, is necessary.įortiDDoS includes the Fortinet DDoS attack mitigation appliance, which provides continuous threat evaluation and security protection for Layers 3, 4, and 7.Security is a one of the foundational design principles and also a key design area that must be treated as a first-class concern within the mission-critical architectural process. Provision extra bandwidth: It may not stop the attack, but it will help the network deal with spikes in traffic and lessen the impact of any attack.ĭDoS attacks are evolving, becoming more sophisticated and powerful, so organizations require solutions that use comprehensive strategies-such as advanced reporting tools and analytics-to monitor countless threat parameters simultaneously. Identify critical systems and normal traffic patterns: The former helps in planning protection, and the latter helps in the early detection of threats.ĥ. Create a protection plan: Create checklists, form a response team, define response parameters, and deploy protection.Ĥ.
Run tests to simulate DoS attacks: This will help assess risk, expose vulnerabilities, and train employees in cybersecurity.ģ. Monitor your network continually: This is beneficial to identifying normal traffic patterns and critical to early detection and mitigation.Ģ. The following are some high-level best practices for DoS and DDoS protection:ġ. Tracing of source(s): The use of a botnet in a DDoS attack means that tracing the actual origin is much more complicated than tracing the origin of a DoS attack.In contrast, a DoS attack typically uses a script or a tool to carry out the attack from a single machine. Manner of execution: A DDoS attack coordinates multiple hosts infected with malware (bots), creating a botnet managed by a command-and-control (C&C) server.Traffic volume: A DDoS attack employs multiple remote machines (zombies or bots), which means that it can send much larger amounts of traffic from various locations simultaneously, overloading a server rapidly in a manner that eludes detection.The increased speed of attack makes detecting it more difficult, meaning increased damage or even a catastrophic outcome. Speed of attack: Because a DDoS attack comes from multiple locations, it can be deployed much faster than a DoS attack that originates from a single location.
On the other hand, a DDoS attack comes from multiple remote locations, disguising its origin. In fact, a proficient firewall can do this. Ease of detection/mitigation: Since a DoS comes from a single location, it is easier to detect its origin and sever the connection.There are other differences, however, involving either their nature or detection, including:
The principal difference between a DoS and a DDoS is that the former is a system-on-system attack, while the latter involves several systems attacking a single system.
