  5. Click Save.
  6. The AWS License Agreement is displayed. You must read and agree with the license terms to be able to continue.

Step 3 – Install BEST on Instances

To protect instances with Security-as-a-Service for AWS, you must install BEST (the client software) on each of them. BEST uses automatic (default) scan modes for EC2 instances set on Central Scan with Bitdefender Security Server hosted in the corresponding AWS region, with fallback on Hybrid Scan (with Light Engines using in-the-cloud scanning and, partially, the local signatures).

Preparing for BEST Installation

Prepare for Silent Agent installation as follows:

  1. Make sure the instances you want to protect run a supported operating system.
  2. BEST has the ability to remove competitor Antivirus solutions. Should to automatic removal fail, uninstall (not just disable) any existing antimalware software from instance. Running other security software simultaneously with Security-as-a-Service for AWS may affect their operation and cause major problems with the system. 
  3. The installation requires administrative privileges. Make sure to have all the necessary credentials at hand (for example, the private keys of your Amazon EC2 key pairs).
  4. Configure the Amazon EC2 security groups to allow SSH and Remote Desktop Protocol access from your computer and SSH access from the Security Console instance.
  5. If you run firewall software on your instances, make sure to configure it to allow access to the Security-as-a-Service for AWS communication ports.

Local Installation

You connect to individual instances via a SSH or Remote Desktop client and use the installation link from Security Console to download and install Silent Agent locally.

To obtain the download links for the installation files:

  1. Connect to Security Console using your company account.
  2. Go to the Computers > Installation Areapage.
  3. Click Installation Link. The window that appears provides you with the download links for the Windows web installer and the Linux installation script.

Run the installation file using administrator/root privileges.

Remote Installation

On instances running Linux operating systems, you can install BEST remotely, from Security Console. For any of these methods, you must first specify the remote authentication credentials:

  1. Connect to Security Console using your Administrator's Account.
  2. Go your name or company's name in the right upper corner of the page -> Credentials Manager.
  3. Under Virtualization, click Amazon Credentials. You can view the list of key names imported from your AWS account and detailed information about them.
  4. For each key name, you must specify the private key and, if needed, complete the list of user names to authenticate with. To specify the necessary credentials, click the Edit icon in the Action column. You can either upload the Amazon private key file or insert its content in the text box. You can remove or add user names as needed.

Remote Installation. To remotely install BEST from the GravityZone Security Console:

  1. Go to the Computers > View Computers page. This page displays your Amazon EC2 instances.
  2. Click the Show menu located above the table (to the left) and choose Unmanaged Computers.
  3. Select the check boxes corresponding to the Linux instances on which you want to install protection. Use the menu under the OScolumn to filter instances by operating system.
