๐Ÿฅณ mondoo 5.18.0 is out!

๐ŸŽ‰ NEW FEATURESโ€‹

** Use Mondoo to verify certificate chains **

You can now use the isVerified field on the certificate resource to check whether or not a certificate chain is valid:

tls("mondoo.com").certificates {
subject.commonName
isVerified
}
tls.certificates: [
0: {
isVerified: true
subject.commonName: "mondoo.com"
}
1: {
isVerified: true
subject.commonName: "R3"
}
2: {
isVerified: true
subject.commonName: "ISRG Root X1"
}
]

** Use Mondoo to query CloudWatch metrics on AWS resources **

Mondoo can now pull CloudWatch statistics for AWS resources. For instance, you can use Mondoo to query the number of invocations and errors for a Lambda function. This can be used to assess error rates, or to detect un-used resources.

Note: Mondoo queries CloudWatch Statistics for the last 24h of data, in 1h intervals.

aws.cloudwatch.metricstatistics(namespace: "AWS/EBS", region: "us-east-1", name: "VolumeTotalReadTime") {
label
datapoints {
maximum
average
sum
}
}
aws.cloudwatch.metricstatistics: {
datapoints: [
0: {
average: 0.0004509803921568627
maximum: 0
sum: 0.22999999999999998
}
]
label: "VolumeTotalReadTime"

or

aws.cloudwatch.metrics {
name
namespace
statistics {
label
datapoints
}
}
  1512: {
statistics: {
datapoints: []
label: "CallCount"
}
namespace: "AWS/Logs"
name: "CallCount"
}
1513: {
statistics: {
datapoints: []
label: "CallCount"
}
namespace: "AWS/Usage"
name: "CallCount"
}
1514: {
statistics: {
datapoints: []
label: "ThrottleCount"
}
namespace: "AWS/Usage"
name: "ThrottleCount"
}
1515: {
statistics: {
datapoints: []
label: "CallCount"
}
namespace: "AWS/Usage"
name: "CallCount"
}

** Enhanced assessment of yum repo file contents through file field **

Prior to this release, Mondoo could display a list of all configured yum repos. With this new improvement, Mondoo can now not only list all the configured repositories, but inspect the file for each yum repo definition in /etc/yum.repos.d.

With the new file field, the contents are also now available to Mondoo:

yum.repos {
name
file {
path
content
}
}
yum.repos: [
0: {
name: "AlmaLinux 8 - AppStream"
file: {
path: "/etc/yum.repos.d/almalinux.repo"
content: "# almalinux.repo

** Use Mondoo to test that files exist, but have no content **

Mondoo can now detect that an empty file exists at an expected location. One common use case for this test is to detect files written in error to a location that would otherwise be a filesystem or chroot mount point.

We've added a new field to the file resource to query if the file or directory is empty:

file("/my/empty/file").empty;
file.empty: true
