Encryption - SNIA on Data, Networking & Storage

Applied Cryptography Techniques and Use Cases

The rapid growth in infrastructure to support real time and continuous collection and sharing of data to make better business decisions has led to an age of unprecedented information storage and easy access. While collection of large amounts of data has increased knowledge and allowed improved efficiencies for business, it has also made attacks upon that informationâ€”theft, modification, or holding it for ransom â€” more profitable for criminals and easier to accomplish. As a result, strong cryptography is often used to protect valuable data.

The SNIA Networking Storage Forum (NSF) has recently covered several specific security topics as part of our Storage Networking Security Webcast Series, including Encryption 101, Protecting Data at Rest, and Key Management 101. Now, on August 5, 2020, we are going to present Applied Cryptography. In this webcast, our SNIA experts will present an overview of cryptography techniques for the most popular and pressing use cases. We’ll discuss ways of securing data, the factors and trade-off that must be considered, as well as some of the general risks that need to be mitigated. We’ll be looking at:

Key Management FAQ

Key management focuses on protecting cryptographic keys from threats and ensuring keys are available when needed. And it’s no small task. That why the SNIA Networking Storage Forum (NSF) invited key management and encryption expert, Judy Furlong, to present a “Key Management 101” session as part our Storage Networking Security Webcast Series. If you missed the live webcast, I encourage you to watch it on-demand as it was highly-rated by attendees. Judy answered many key management questions during the live event, here are answers to those, as well as the ones we did not have time to get to.

Q. How are the keys kept safe in local cache?

Encryption Q&A

Ever wonder how encryption actually works? Experts, Ed Pullin and Judy Furlong, provided an encryption primer to hundreds of attendees at our SNIA NSF webcast Storage Networking Security: Encryption 101. If you missed it, It’s now available on-demand. We promised during the live event to post answers to the questions we received. Here they are:

Q. When using asymmetric keys, how often do the keys need to be changed?

A. How often asymmetric (and symmetric) keys need to be changed is driven by the purpose the keys are used for, the security policies of the organization/environment in which they are used and the length of the key material. For example, the CA/Browser Forum has a policy that certificates used for TLS (secure communications) have a validity of no more than two years.

Encryption 101: Keeping Secrets Secret

April 20, 2020April 20, 2020 Alex McDonald Leave a comment

Encryption has been used through the ages to protect information, authenticate messages, communicate secretly in the open, and even to check that messages were properly transmitted and received without having been tampered with. Now, it’s our first go-to tool for making sure that data simply isn’t readable, hearable or viewable by enemy agents, smart surveillance software or other malign actors.

But how does encryption actually work, and how is it managed? How do we ensure security and protection of our data, when all we can keep as secret are the keys to unlock it? How do we protect those keys; i.e., “Who will guard the guards themselves?”
