Description :   X Certificate and Key management is a graphic interface for managing

: intended as a small CA for creation and signing certificates. It uses the
: OpenSSL library for the cryptographic operations.
:   Certificate signing requests (PKCS#10), certificates (X509v3), the signing
: of requests, the creation of self-signed certificates, certificate revocation
: lists and SmartCards are supported. For an easy company-wide use, customizable
: templates can be used for certificate and request generation. The PKI structures

Sandbox apache (httpd) for better security.

Table of contents for Fedora Security

  1. Sandbox apache (httpd) for better security.

Apache/httpd is something which you would like to have contained. And now fedora provides a native way/mechanism to to so with virt-sandbox-service. With this, you can create a virtualized sanbox service and then connect/list/manage such with virsh.

We will be using LXC.

Basically its couple of commands and you have a contained service running.

# List all the containers
virsh -c lxc:/// list

# Create the sandbox, all default parameters. Will take dhcp address.
virt-sandbox-service create -C  --username amitag -u httpd.service httpd_conta

# Create the container with static IP.
virt-sandbox-service create -C  --username amitag -u httpd.service -N \
address=192.168.122.11/24%192.168.122.255  httpd_conta#Enable and start the service.
virt-sandbox-service start httpd_conta
virt-sandbox-service enable httpd_conta#Delete the container if not required any more.
virt-sandbox-service delete  httpd_conta
