Difference between network forensic and computer forensic. Computer forensics (cyber forensics) refers to the collection, reporting digital data, applying computer investigation and analysis techniques to solve a case and provide evidence also. Investigators sometimes use proprietary forensic applications and software programs to examine system hard drives. On the other hand Network forensics involves investigations that obtain and analyze from network or network events. Network forensics is the capture, recording, and analysis of network in order to know the origin of security attacks. It applies to all types of IT data investigations. _________________________________________________ What is trusted advisor why is it imp be sepc ___________________________________________________ Five type of security events. ________________________________________________________ Three types of cloud computing model? Exaplain each type Software as a Service (SaaS) - Application that can be accessed from anywhere in the world  as long as you have a computer with an internet connection - (e.g Salesforce.com, gmail, yahoo mail, hotmail etc.,)  - software distribution model in which applications are  provided by service provider and make them available  to clients over a network. Application are accessible  from anywhere as long as you have internet.   - Web access to commercial software  • Software is managed from a central location  • Software delivered in a “one to many” model  • Users not required to handle software upgrades and patches  • Application Programming Interfaces (APIs) allow for integration between  different pieces of software

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
