3.8 Explain how resiliency and automation strategies reduce risk. Flashcards
Templates
Like a baseline for reports - providing a means to summarize and document results of threat source identification, characterization, vulnerabilities, and impacts.
Elasticity
a major feature of cloud computing, meaning the ability to scale up resources as needed. (not shrinking)
Scalability
scaling both up and down, scalability is always a desired attribute of any system.
Redundancy
refers to systems that either are duplicated or fail over to other systems in the event of a malfunction
Fault tolerance
When you have a backup so that you can tolerate an outage or failure.
High Availability
when a service is available 99.999%
RAID
Redundant Array of Independent Disks
RAID 0
(Striping) minimum of 2 harddrives. data is written alternating to the two drives, NOT A BACKUP.
RAID 1
(Mirror) only 2 harddrives. All data is an both drives
RAID 3
(Disk Striping with a Parity Disk) Minimum of three HDD. stripping on two HDDs, and third HDD with a copy of both.
RAID 5
(Striping with Parity) Stripping on first 60% all three disks last 30% on each HDD is a copy of the others.
