The Security Digest: #50

Hello and welcome to TSD, your weekly blog post with top of mind security issues. TSD began as an internal newsletter that our Security Lead, Daniel Tobin, would circulate to the team each Tuesday. It proved to be a great resource for all of us so we thought, why not share it with all of you? Our hope is that it helps make you just a bit more secure.

Check back here every Tuesday for more TSD or sign up below to stay in the loop!

Owl fun and facts:

A Powerful owl from Nick Bradsworth for Phys.org

Researchers have just published an article after tracking Powerful owls in Australia and have found that they are increasingly found in urban areas. “Powerful owls are Australia’s largest, measuring 65 centimeters from head to tail and weighing a hefty 1.6 kilograms. They’re found in Australia’s eastern states, except for Tasmania.” The owls had been previously thought to only live in old growth forests, but those forests are diminishing and the owls are finding new homes. Read the summary of the research at Phys.org.

A Shout Out:

Marco Lancini, the author behind CloudSecList, released his latest entry into this “Continuous Visibility into Ephemeral Cloud Environments” blog series. Security Logging in Cloud Environments – AWS is a reference architecture for using only AWS services to be able to enable security logging for a multi-account AWS environment. This is a great overview as well hitting on key points even if you are already using AWS cloud logging like enabling S3 Object Lock in Compliance Mode for logs stored in S3.
