Schedule, syllabus and examination date

Course content

Network and communications security is an important part of information security: a large portion of IT-related attacks are performed either using network connections or are directed at network infrastructures. .

A majority of modern systems also depend on communication over networks. This course focuses on the application of cryptographic protocols and network protection techniques to secure computer networks and communication.

Learning outcome

After completing this course:

  • you will have knowledge about cryptographic foundations of network and communications security
  • you will be able to manage cryptographic keys, certificates and crypto parameters
  • you will understand network/communication security protocols
  • you will be able to configure network perimeter security and security monitoring
  • you will have knowledge about security of global, local and wireless networks
