# harbian audit Debian Linux 9 Benchmark
## 1.2 Enable Option for signature of packages from a repository (scored)
### Profile Applicability
Level 2
### Description
The operating system must prevent the installation of software, patches, service packs, device drivers, or operating system components from a repository without verification they have been digitally signed using a certificate that is issued by a Certificate Authority (CA) that is recognized and approved by the organization.
### Rationale
Changes to any software components can have significant effects on the overall security of the operating system. This requirement ensures the software has not been tampered with and that it has been provided by a trusted vendor. Accordingly, patches, service packs, device drivers, or operating system components must be signed with a certificate recognized and approved by the organization. Verifying the authenticity of the software prior to installation validates the integrity of the patch or upgrade received from a vendor. This verifies the software has not been tampered with and that it has been provided by a trusted vendor. Self-signed certificates are disallowed by this requirement. The operating system should not have to verify the software again. This requirement does not mandate DoD certificates for this purpose; however, the certificate used to verify the software must be from an approved CA.
### Aduit
Verify the operating system prevents the installation of patches, service packs, device drivers, or operating system components from a repository without verification that they have been digitally signed using a certificate that is recognized and approved by the organization. Check that apt verifies the signature of packages from a repository prior to install with the following command:
```
# grep AllowUnauthenticated /etc/apt/ -r
APT::Get::AllowUnauthenticated "true";
```
If "AllowUnauthenticated" is set to "true", this is a finding.
### Remediation
Delete the configuration line containing "AllowUnauthenticated".
## 1.3 Enable verify the signature of local packages (scored)
### Profile Applicability
Level 2
### Description
The operating system must prevent the installation of software, patches, service packs, device drivers, or operating system components of local packages without verification they have been digitally signed using a certificate that is issued by a Certificate Authority (CA) that is recognized and approved by the organization.
### Rationale

Check that apt verifies the signature of packages from a repository prior to install with the following command:
```
# grep -v "^#" /etc/dpkg/dpkg.cfg | grep no-debsig
no-debsig
```
If "no-debsig" is set, this is a finding.
### Remediation
Delete the configuration line containing "no-debsig".
## 2.26 Set nosuid option for /home filesystem/Partition (scored)
