There are many different ways to backup data. In this video, you’ll learn about incremental backups, differential backups, compare NAS to SAN storage, and more. << Previous Video: Replication Next: Resiliency >>     If you’re using an operating system based in Microsoft Windows, there is a bit associated with every file system object called […]

Replication is a useful method of maintaining application and data availability. In this video, you’ll learn about SAN replication, VM replication, and a comparison of on premises and cloud redundancy. << Previous Video: Power Redundancy Next: Backup Types >> When we deploy an application instance, it’s very common that the computing engine that is able

Maintaining a power source is an important part of any security strategy. In this video, you’ll learn about UPS systems, generators, dual-power supplies, and power distribution units. << Previous Video: Network Redundancy Next: Replication >> Perhaps the primary resource we need to be able to operate our computers, our laptops, and mobile devices is power.

There are many methods of maintaining the uptime and availability of networks. In this video, you’ll learn about load balancing, NIC teaming, port aggregation, and more. << Previous Video: Disk Redundancy Next: Power Redundancy >>     One of the easiest ways to maintain uptime and availability on the network is to include a load

A goal of any security professional is to maintain constant access to data. In this video, you’ll learn about disk redundancy and using RAID to increase uptime and availability. << Previous Video: Multi-factor Authentication Next: Network Redundancy >> In this next series of videos we’re going to talk about redundancy. This is how we duplicate

We use many different factors during the authentication process. In this video, you’ll learn about the AAA framework, multi-factor authentication factors, and multi-factor authentication attributes. << Previous Video: Biometrics Next: Disk Redundancy >>     We’re all familiar with the process of authenticating into a system. Usually you use a username, a password, and perhaps

There are many ways to authenticate someone based on a biometric feature. In this video, you’ll learn about fingerprint scanners, retinal scanners, voice recognition, and more. << Previous Video: Authentication Methods Next: Multi-factor Authentication >> A biometric authentication factor refers to something you are, this would be something like a fingerprint. For example, fingerprint scanners

We use many different technologies during the authentication process. In this video, you’ll learn about directory services, federation, attestation, and more. << Previous Video: Automation and Scripting Next: Biometrics >>     Many operating systems will use a feature known as directory services. This is a central database that stores usernames, passwords, computers, printers, and
