In the face of rising cyber attacks, businesses often confront the instinct to shut down systems to contain potential damage. However, experts warn that this reaction, while understandable, may not always be the best response. Premature shutdowns can complicate incidents, leading to operational disruptions and a more challenging recovery process.
According to Chad LeMaire, deputy CISO at ExtraHop, several factors can define the severity of a cyber attack for an organization, primarily reliant on preparation. Companies that invest in comprehensive incident response plans, ongoing monitoring, and a culture of cyber resilience stand far better equipped to manage attacks effectively.
Shutting down systems can lead to unintended consequences, particularly during ransomware incidents, where abrupt shutdowns might corrupt encrypted files, complicating data restoration efforts. Instead, maintaining essential operations while isolating compromised systems is recommended. This strategic approach aims to minimize disruption and prevent the attack from escalating.
Long-term resilience against cyber threats requires a multifaceted approach, including robust data backup solutions and efficient real-time threat detection. Furthermore, effective communication during an incident—internally and externally—is crucial. Such preparedness ensures that misinformation does not exacerbate an already tense situation and helps maintain trust with customers.
