A Weekend in Incident Response #15: Responding to Increasingly Common DDoS Attacks Through Automated Playbooks
Cyber-attackers never stop inventing new and more creative methods and techniques that are supposed to be more difficult to prevent. One of the most common types of attacks nowadays are the DDoS attacks (Distributed Denial of Service attacks) , which are on the rise recently, unlike data breaches, according to the 2017 Cyber Incident & Breach Response Guide issued by the Online Trust Alliance.
Mitigating DDoS attacks is complicated and time-consuming. They often last several days and even weeks, bringing an organization’s operations to a complete halt for prolonged periods of time. It takes a coordinated effort from an organization’s CSIRT, C-level and its Internet Service Provider (ISP). Since it can take a lot of time to recover from a DDoS attack, it’s essential to have a response plan in place that is specifically designed to respond to these types of cybersecurity incidents. This will help reduce the team’s response time, contain the damage, and resume operations as soon as possible.
DDoS Attack Playbooks
In order to prepare for a future DDoS attack, it’s recommended that organizations utilize a cyber incident response platform, which has the ability todetect, predict and respond to various types of cybersecurity incidents. These platforms provide specialized automated playbooks for the different types of incident, allowing organizations to automate the immediate response to a cybersecurity event and give their SOC and CSIRT the time to focus on recovery and making the organization’s systems fully functional as soon as possible.
Effective Containment and Recovery
A typical DDoS attack playbook includes the key aspects of a cyber incident response, such as analysis, containment, remediation, recovery, and post-incident actions. By employing such a playbook, the organization can quickly determine the specific part of the infrastructure that has been affected by the attack, so that the team can know the necessary actions required to take in order to resolve the incident. A pre-defined playbook will help organizations contain the damage by notifying the SOC and CSIRT on how to block the DDoS attack based on the analysis performed by the incident response platform.
After you have taken the proposed actions to contain the incident, the playbook will guide you through the remediation process. It will involve contacting your ISP and notifying law enforcement, which is where a cyber incident response platform’s capability to create automated incident reports comes in handy, too.
Finally, if you are utilizing a cyber incident response platform, you will have the possibility to enhance your preparedness for future cybersecurity events, by creating statistical reports that contain all the necessary metrics, which you can use to adjust your response to different types of attacks.
