Step 3: Install trivy

In the next step, you can choose to install trivy by using any of the below methods depending on your needs and requirements.

a) Using Repo

First you have to download and install all the packages required for trivy installation using sudo apt-get install wget apt-transport-https gnupg lsb-release command as shown below.

cyberithub@ubuntu:~$ sudo apt-get install wget apt-transport-https gnupg lsb-release

Then install GPG key using below wget command to check the integrity of the downloaded package.

cyberithub@ubuntu:~$ wget -qO - https://aquasecurity.github.io/trivy-repo/deb/public.key | sudo apt-key add -
Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).
OK

You can now add the trivy repo by using echo deb https://aquasecurity.github.io/trivy-repo/deb $(lsb_release -sc) main | sudo tee -a /etc/apt/sources.list.d/trivy.list command as shown below.

cyberithub@ubuntu:~$ echo deb https://aquasecurity.github.io/trivy-repo/deb $(lsb_release -sc) main | sudo tee -a /etc/apt/sources.list.d/trivy.list

Step 6: Using Trivy

Now that trivy is installed, let's use it to scan a filesystem. Here we are scanning filesystem /home/cyberithub using trivy fs /home/cyberithub command as shown below.

cyberithub@ubuntu:~$ trivy fs /home/cyberithub
2024-01-29T22:00:04.785+0530 INFO Need to update DB

2024-01-29T22:00:20.488+0530 INFO Number of language-specific files: 0

Similarly, if you have a container image to scan then you can use trivy image <image_name> command. For example, here we are scanning ubuntu image by using trivy image ubuntu command as shown below.

cyberithub@ubuntu:~$ trivy image ubuntu
2024-01-31T23:23:39.902+0530 INFO Need to update DB

................................................

 

 

Step 7: Check all available options

You can check all the options available with trivy utility using trivy --help command as shown below.

cyberithub@ubuntu:~$ trivy --help
Scanner for vulnerabilities in container images, file systems, and Git repositories, as well as for configuration issues and hard-coded secrets

Usage:
trivy [global flags] command [flags] target
trivy [command]

Examples:
# Scan a container image
$ trivy image python:3.4-alpine

# Scan a container image from a tar archive
$ trivy image --input ruby-3.1.tar

# Scan local filesystem
$ trivy fs .

# Run in server mode
$ trivy server
.........................................

 

 

Step 8: Uninstall Trivy
