ATC-PUBLIC-KEY-INFRA - Public Key Infrastructure (PKI)


Duration: 5.0 days

This Public Key Infrastructure – Implement and Manage course helps any individual to gain knowledge in managing robust PKI and having better understanding of topics surrounding public key infrastructure. Moreover, the PKI course is a preparation for the increasingly critical component – which ensures confidentiality, integrity, and authentication in an enterprise. Our PKI course provides the knowledge and skills necessary to select, design and deploy PKI, to secure existing and future applications within your organization. It also gives a deeper look into the foundations of cryptography and the working principles of the algorithms being used.

Throughout the whole course, participants will gain in-depth knowledge on the following topics:

  • Legal aspects of a PKI
  • Elements of a PKI 
  • PKI management 
  • Trust in a digital world 
  • Digital signature implementation 
  • Trust models 
  • Smart Cards 
  • SSL 
  • OCSP

After completing the PKI course, every individual will be able to successfully design, setup, deploy, Troubleshoot and manage a public key infrastructure (PKI). This is a 5-day course is considered essential for anyone who needs to understand Public Key Infrastructure (PKI) and the issues surrounding its implementation. It covers the issues and technologies involved in PKI in-depth and gives hands-on practical experience of setting up and maintaining a variety of PKI solutions. Detailed knowledge of issues surrounding PKI helps to put recent attacks which have appeared in the news headlines into context and enable valid decisions to be made about their relevance to your organization.
