A cryptographic hash can be used for many different tasks. In this video, you’ll learn about hashing, collisions, digital signatures, and more. << Previous Video: Symmetric and Asymmetric Encryption Next: Randomizing Cryptography >> A cryptographic hash allows you to take any amount of data– it can be a small bit of text, or it can […]

If you’re planning to implement cryptography, then you’ll probably be using either symmetric encryption or asymmetric encryption. In this video, you’ll learn about both of these valuable encryption mechanisms. << Previous Video: Cryptography Concepts Next: Hashing and Digital Signatures >> If you’ve implemented symmetric encryption using a single shared key for both the encryption process

The basics of cryptography are valuable fundamentals for building a secure network. In this video, you’ll learn about cryptographic terms, the value of the key, the concepts of confusion and diffusion, and more. << Previous Video: Data Roles and Retention Next: Symmetric and Asymmetric Encryption >> Cryptography is derived from the Greek word “kryptos,” which

Who owns your data, and how long do you keep copies of your data? In this video, you’ll learn about specific data roles and options for data retention. << Previous Video: Handling Sensitive Data Next: Cryptography Concepts >> In most organizations, data doesn’t exist on its own. There is a relationship between the data and

Different types of data need to be uniquely managed. In this video, you’ll learn about labeling sensitive data and some common sensitive data types. << Previous Video: Data Destruction Next: Data Roles and Retention >> In your organization, you’re going to be working with lots of different kinds of data. But not all of the

What’s the best way to permanently remove data from a storage device? In this video, you’ll learn about the challenges associated with destroying data. << Previous Video: Security Controls Next: Handling Sensitive Data >> As we think about the lifecycle of all of our systems and data, at some point there will be a need

There are many ways to prevent or minimize the impact of a security event. In this video, you’ll learn about the different security control categories. << Previous Video: Continuity of Operations Next: Data Destruction >> There are many different security risks out there, and there are all different shapes and forms. We have to protect

Maintaining the technology for an organization can be a challenge in the best of circumstances. In this video, you’ll learn about planning for disaster with tabletop exercises, after-action reports, failover plans, and more. << Previous Video: Geographic Considerations Next: Security Controls >> If you’ve built a plan for a security incident, it’s always a good

Selecting the location of a disaster recovery site isn’t as simple as it may seem. In this video, you’ll learn about the challenges of geographic location, off-site backups, and issues with international data and travel. << Previous Video: Application Recovery Next: Continuity of Operations >> Whenever you’re preparing for any kind of incident, you must

When a security incident occurs, you’ll need to get applications running again as quickly as possible. In this video, you’ll learn about application restoration priorities and backup strategies. << Previous Video: Disaster Recovery Sites Next: Geographic Considerations >> When you’re recovering applications, some applications may have a higher priority than others. Applications that are customer
