ABSTRACT
With the rising cases of cyberattacks not only on the critical infrastructures but also on private and institutional network infrastructure, there is a rising need for cybersecurity professionals. Many organizations spend a hefty amount on training and certifications of their personnel in network security. With the rising demand for trained professionals, several educational institutes have developed various network security courses, ACRs, and training programs. DoD projects, EUH 2020 project, and similar projects were initiated with the aim of inculcating cyberattack preparedness and skillsets in the students. They also focused on providing platforms for conducting research on the ever-dynamic cyberwarfare scenario, new attacks, and threats. The use of scalable, competitive, user-friendly ACR testbeds has assisted many academic institutes in training students on cybersecurity aspects. This is advantageous as students develop the necessary industrial-level skillset with necessary certifications. This chapter discusses some of the prominent simulation-based and emulation-based ACRs. It also summarizes all the advantages and features of the discussed ACRs in tabular form at the end of respective sections.
