When will I have access to the lectures and assignments?

To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.

What will I get if I subscribe to this Specialization?

When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.

Is financial aid available?

Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.

There are 2 modules in this course

This course focuses on Domain 4 of the CISSP exam, covering network security. It begins with an in-depth look at the OSI Reference Model. At each layer, we will discuss functionality, threats/vulnerabilities and common mitigation strategies. In addition, we will focus on firewalls, proxy servers and remote access solutions. It also covers the security services that cryptography can provide and examine common terms like initialization vectors, salts, hashing, algorithms and keys. We will then build on this foundation to explore symmetric, asymmetric and hybrid cryptography and look at its practical implementations.
