Security and Compliance: What 8.5 Offers

When you deploy an ISO, you inherit the security posture of that version. Oracle Linux 8.5 introduced fapolicyd (File Access Policy Daemon) by default. This is a kernel-level application whitelisting tool—similar to SELinux but focused on executables.

To check if fapolicyd is running:

sudo systemctl status fapolicyd

Additionally, 8.5 includes the OpenSCAP suite by default. You can scan your machine against a DISA STIG or CIS profile:

sudo oscap xccdf eval --profile cis --report scan-report.html /usr/share/xml/scap/ssg/content/ssg-ol8-ds.xml

Step 1: Access the Oracle Software Delivery Cloud

Navigate to edelivery.oracle.com. This is Oracle’s official electronic software distribution portal.

Mount the ISO as a local repo:

mkdir /mnt/iso
mount -o loop OracleLinux-8.5-x86_64-dvd1.iso /mnt/iso

Create a repo file: /etc/yum.repos.d/local.repo

[local-baseos]
name=Local Oracle Linux 8.5 BaseOS
baseurl=file:///mnt/iso/BaseOS
enabled=1
gpgcheck=0

[local-appstream]
name=Local Oracle Linux 8.5 AppStream
baseurl=file:///mnt/iso/AppStream
enabled=1
gpgcheck=0

Now you can run dnf install without a network.
