Yo Wuddup Everybody It’s Ya Boi James here coming at you with a new blog post!

Today I’m going to detail the process of installing the SIFT Workstation on Ubuntu 20.04.3

Step 1: Let’s Download Our Prerequisite Files

• Grab the SANS Files Here: https://github.com/teamdfir/sift-cli/releases/tag/v1.14.0-rc1 Make sure you grab the archive, as well as the “sift-cli-linux”, “sift-cli-linux.sig”, and “sift-cli.pub” files, which will allow us to verify the integrity of the files later on.

• Grab a copy of GO that way we can compile and use Cosign which is the program we’ll be using to test the integrity of the files as mentioned above.

  wget https://dl.google.com/go/go1.16.4.linux-amd64.tar.gz
  

Step 2: Time to Install/Configure Go

• Unarchive the GO file. You’ll notice we pulled a specific version of GO, 1.16.4. The reason for this is because Cosign requires us to use that version specifically for the install at this current time.

  sudo tar -xvf go1.16.4.linux-amd64.tar.gz
  

• Now we’ll be setting up the GO environment

  sudo mv go /usr/local
  

• The next two lines entail variables for the environment
• GOROOT is for compiler/tools that comes from go installation.
• GOPATH is for your own go projects / 3rd party libraries in our case Cosign

  export GOROOT=/usr/local/go
  

  export GOPATH=$HOME/Projects/Proj1
  

  export PATH=$GOPATH/bin:$GOROOT/bin:$PATH
  

• Now you should be able to run GO by simply typing “go” and specifying a command. In our case let’s simply check the version to make sure everything’s up and running.

  go version
  

• At this point we should have everything necessary to get moving on installing SIFT. just one last thing.

Step 3: Installing Cosign

  go install github.com/sigstore/cosign/cmd/cosign@latest

• Once it’s complete you should be able to run the next command to verify the SIFT Signatures

  cosign verify-blob --key sift-cli.pub --signature sift-cli-linux.sig sift-cli-linux
  

• Now to make the SIFT manager so we can install then update/manage SIFT as needed

  sudo mv sift-cli-linux /usr/local/bin/sift
  

• We’ll use chmod to make the file executable

  chmod 755 /usr/local/bin/sift
  

• 755 means read and execute access for everyone and also write access for the owner of the file

  Sudo apt-get update
  

• If all has gone well now, we should be able to run our long awaited command :)

  sudo sift install
