The Federal Bureau of Investigation (FBI), the Cybersecurity and Infrastructure Security Agency (CISA), and the Multi-State Information Sharing and Analysis Center (MS-ISAC) have issued collaborative instructions for reacting to distributed denial-of-service (DDoS) assaults.
“Organizations should include steps to address these potential effects in their incident response and continuity of operations playbooks,” the three agencies wrote in a recent statement.
Denial-of-service (DDoS) attacks, according to the alert, normally have minimal impact on the confidentiality and integrity of systems and data, but they can be used to deflect attention away from other forms of attacks, such as malware deployment and data exfiltration.
“In a progressively interconnected world with additional post-pandemic remote connectivity requirements, maintaining the availability of business-essential external-facing resources can be challenging for even the most mature IT and incident response teams,” the statement said. “It is impossible to completely avoid becoming a target of a DDoS attack.”
The agencies outline a few steps companies should take to avoid, if expecting, or after such an attack. These include
Before an attack:
- Understand your critical assets and services.
- Understand how your users connect to your network.
- Enroll in a DDoS protection service.
If you are expecting an attack:
- Confirm the DDoS attack
- Contact your ISP
- Understand the nature of the attack
- Deploy mitigations
After the attack:
- Continue to monitor other network assets
- Update your DDoS response plan
- Proactively monitor your network to quickly identify DDoS attacks.
DDoS assaults are a sort of cyberattack that target programs or websites and aims to exhaust the target system’s resources, rendering it unreachable to legitimate users.
Such attacks are designed to focus on server vulnerabilities in order to overload network resources or use these resources by reflecting a large volume of network traffic onto the target. They may also attempt to overload the target’s connection (protocol) or application (compute or storage) resources.
When the overloaded traffic comes from several sources working together, the attack is classified as a DDoS. The most prevalent source of DDoS assaults is botnets, which are networks of hacked devices such as PCs, IoT devices, and servers.
