Package Installation¶

RPM Installation¶

OSSEC’s RPMs are made available by AtomiCorp.

The RPMs can be installed by adding the AtomiCorp yum repository:

# wget -q -O - https://updates.atomicorp.com/installers/atomic | sh

Next use yum to install the specific packages. For an OSSEC server run:

# yum install ossec-hids ossec-hids-server

And for an agent run:

# yum install ossec-hids ossec-hids-agent

Deb Installation¶

OSSEC’s DEB packages are made available by Atomicorp.

Run the Repo installer:

# wget -q -O - https://updates.atomicorp.com/installers/atomic | sudo bash

Update the repository:

# apt-get update

Install OSSEC HIDS server/manager:

# apt-get install ossec-hids-server

Or install OSSEC HIDS agent:

# apt-get install ossec-hids-agent

pkg Installation¶

Some of the BSD operating systems offer OSSEC packages you can use. Here you have FreeBSD and OpenBSD as example.

• FreeBSD

You are going to work together with pkg here. Just choose which type of setup you need (agent, local monitoring, or server/manager) and install the respective OSSEC package.

Should you opt to install an OSSEC Server/Manager:

# pkg install ossec-hids-server

If you want to install an OSSEC Agent:

# pkg install ossec-hids-agent

• OpenBSD

Here you must work with pkg_add instead of pkg, but no worries it’s the same concept.

As it only offers one package, here is how to install OSSEC HIDS on OpenBSD:

# pkg_add ossec-hids
