Defending Against Black Nurse DoS Attacks

Denial-of-service (DoS) attacks are a popular way to cause targeted service disruptions, typically for extended periods of time. The relative ease and low cost of launching such attacks, aided by a serious lack of any viable defense mechanisms, have made them one of the most common threats on the Internet. In the past, Internet Control Message Protocol (ICMP)-based DoS attacks have used multiple hosts infected with botnets to launch an overwhelming distributed DoS (DDoS) attack to take down major Web servers or perimeter firewalls. Now, researchers have discovered a new attack technique, called “Black Nurse,” that enables a single computer to generate 15 Mbps of bandwidth traffic and take down major network firewalls.

It has long been postulated as a goal or used to convey that a business needs to be ready for the unpredictable that can and will arise in a volatile cyber-risk climate. However, we have seen that there is a disconnect between current practices for evaluating & leading cyber programs, and understanding, measuring, & building true cyber resiliency.

Embracing Security Operations in the Educational Sector

whitePaper | December 22, 2022

Nearly every part of the educational sector has fallen victim to a cyberattack, from elementary schools to universities. Securing education is no longer a “nice to have” but a “must do” and is a growing concern among the global educational community. Creating and maintaining effective information security and cybersecurity operations in education comes down to people, processes, and tools. It’s crucial for IT and security leaders across the entire spectrum of educational institutions to find the right balance between the three. While there are success stories of achieving that balance, there’s always more to do to identify, understand, and mitigate cybersecurity risks to these organizations. Establishing and improving existing cybersecurity operations must become a priority.
