Intro
Database security is in greater demand sector in current data era. All the
companies spending colossal sum of money to enhance the security of the
database servers. Oracle came up with Oracle Audit vault and Firewall to
protect and prevent data from internal and external attackers.
It's important to get an understanding of the what is Database Audit Vault
and Database firewall ?
What is DB Audit vault ?
Oracle Audit Vault and Database Firewall (AVDF) is a complete Database Activity Monitoring (DAM) solution that combines native audit data with network-based SQL traffic capture. ... A Quick-JSON collector simplifies ingesting audit data from databases like MongoDB.
What is Database firewall ?
Oracle Database Firewall acts as the first line of defense for databases, helping prevent internal and external attacks from reaching the database. Highly accurate SQL grammar-based technology monitors and blocks unauthorized SQL traffic on the network before it reaches the database.
Make sure to full fill these pre requisites before starting the installation.
In this scenario we are going to install this on virtual box.
Make sure to note vm-network address range and default gateway because we need this to setup vm network and access this using url.
We can download the iso image from :https://edelivery.oracle.com/
Then search for : Oracle Audit Vault and Database Firewall .
This comes with two separate iso images ,
First we need to create a vm with 8gb memory , 250GB hard disk and 1 core.
After that browse the iso to controller IDE . This is pre-setup
installation media consists with database and application installation.
Then it will automatically mount the iso image and start booting from the iso image.
Error:
Solution:
Increase the hdd size 250 or more.
After this step , setup will move to root password configuration.
Now installation will again prompt the iso to continue with other steps.
Again browse the same iso image from controller ide.
I have added two network interfaces here , Network settings information (Chapter 1 - Pre-requites ) is required to setup the network.
1. NAT network to access internet.
2. Vm-host network to access vm via same network range 192.168.56.1.
Feed network information:
On completion of the network setup , installation will move to asm and db installation
Once the repository creation is done setup will apply the GRID RU
Congratulation now installation is complete !!!!!!!!
you can access the web application from below mention url.
Initial access needs root credentials . After that we need to setup
several users to segregate the accounts.
3.4 Setting the Usernames and Passwords of Audit Vault Server Users
Console output:

NOTE :
The Audit Vault Server and Database Firewall server are software
appliances. You must not make any changes to the Linux operating system
through the command line on these servers unless following official
Oracle documentation or under guidance from Oracle Support.
Make sure to full fill these pre requisites before starting the installation.
In this scenario we are going to install this on virtual box.
1 . Pre-requisites
1.1 VM creation
- 8GB - Memory
- 250GB - HDD
- 1 core cpu.
1.2 network settings.
Make sure to note vm-network address range and default gateway because we need this to setup vm network and access this using url.
1.3 Download the image
We can download the iso image from :https://edelivery.oracle.com/
Then search for : Oracle Audit Vault and Database Firewall .
In this case we are going to download Audit Vault and Database 20.4.
This comes with two separate iso images ,
1. audit vault
2. firewall.
2. Installation
First we need to create a vm with 8gb memory , 250GB hard disk and 1 core.
After that browse the iso to controller IDE . This is pre-setup
installation media consists with database and application installation.
Mount iso file:
Then it will automatically mount the iso image and start booting from the iso image.
2.1 Installation Issues : HDD Capacity
We faced a issue when trying to give less capacity for hdd.Error:
Solution:
Increase the hdd size 250 or more.
2.2 Installation issues : Lack of memory
If you tried to install this only with 4GB of memory Installation will failed with below mention error, so make sure to give 8GB to avoid this failure.
2.3 Setup root account password
We have taken few screen shots of the installation get the understanding
of the installation components.
First screen shot shows the disk partitioning . Second screen shot shows
the installation of the requirement rpms.
2.4 Setup network
I have added two network interfaces here , Network settings information (Chapter 1 - Pre-requites ) is required to setup the network.
1. NAT network to access internet.
2. Vm-host network to access vm via same network range 192.168.56.1.
Feed network information:
2.5 Setup Application.
Last two steps of the installation illustrates the application installation and migrating the created repository to asm storage.
Congratulation now installation is complete !!!!!!!!
you can access the web application from below mention url.
3. Web Application Access
Initial access needs root credentials . After that we need to setup
several users to segregate the accounts.
This oracle document link will covers the setup of these accounts for
segregation of duties.
3.4 Setting the Usernames and Passwords of Audit Vault Server Users
(taken from oracle documents)
Set up usernames and passwords for Oracle Audit Vault and Database Firewall (Oracle AVDF).
In the post-install configuration page, you set up usernames and passwords for the following Oracle Audit Vault and Database Firewall users:
Changing the root user password on this screen is optional as it is already set during installation.
Password requirements:
If your password contains Unicode character (such as non-English characters with accent marks), the password requirement is as follow: "between 8 and 30 characters long...etc"
