Furthermore, the reputational damage resulting from an APT can erode customer trust and confidence, leading to long-term consequences that extend beyond immediate financial impacts. In addition to financial implications, APTs can also disrupt business continuity and compromise critical infrastructure. For instance, if an organization relies heavily on its IT systems for day-to-day operations, an APT that targets these systems can halt productivity and lead to cascading failures across departments.
You might consider how this disruption can affect not only internal operations but also external stakeholders, including customers and partners. The interconnected nature of modern business means that the fallout from an APT can ripple through supply chains and ecosystems, amplifying the overall impact on the organization.
Strategies for Detecting and Defending Against Advanced Persistent Attacks
