Step 01 – Playing with Object Storage in GCP – Cloud Storage Back after talking about block and file storage in the last section. Let’s now shift our attention to Object Storage. The object storage service in GCP is cloud storage. What is object storage? What is cloud storage? Let’s talk about that in this specific section. And to get an idea about object storage and cloud storage, let’s start with a demo. What I would do is I would go into cloud console and I would say, cloud cloud…

Step 01 – Getting Started with Google Cloud Run Welcome back. In the previous sections, we talked about Kubernetes. When we talked about Kubernetes, we needed to create a cluster. How about an easier way of deploying containerized applications? That’s the idea behind Cloud run. Cloud Run is container to production in seconds. So you have a container to deploy. You can go to production in seconds. Now, before I do anything, what we’ll do is we’ll start with a demo for Cloud Run. So let’s go over to our…

Step 01 – Getting Started with Google Cloud Functions Welcome back. Let’s get started with Cloud functions. What are Google Cloud functions or GCF? Imagine you want to execute some code when an event happens. A file is uploaded into Object Storage in Google Cloud, which is Cloud Storage, an error log is written to Cloud Logging, or a message is arriving on a queue which is Cloud pub sub. In all these situations, let’s say you want to run some code. When some event happens, you want to run…

Step 00 – Understanding Data States Welcome back. Welcome to this new section on Encryption. In last few sections, we played around with a number of Compute services and before we go into storage and databases, we need to understand encryption. Whenever we’re moving data to the cloud, we want it to be secure and one of the options is to encrypt the data. Let’s understand encryption and the service which is offered by GCP for encrypting your data. In this specific section, let’s get started with understanding the different…

Step 10 – Playing with Disks – Gcloud Welcome back. Instead, let’s look at how we can play with disks from the command line. It’s the same thing that we used when we played with Compute instances gcloud Compute however, instead of instances we have disks. So Gcloud Compute list create Delete resize Snapshot let’s start with doing a simple Gcloud Compute Instances list and before I would be able to do that, let’s launch up Cloud Shell. I’ll open up Cloud Shell in a new window and let’s set…

Step 06 – Taking Snapshots for Persistent Disks Welcome back. In this step, let’s talk about snapshots. What are snapshots? Snapshots are nothing but point in time backups of your persistent disks. You can also schedule snapshots. You can say I would want to create a snapshot every few hours. I can say, I would want to configure a backup every day. You can also auto delete snapshots after a few days. So as part of your scheduling, you can say I would want to take a snapshot every day….

Step 01 – Exploring Block and File Storage in GCP Welcome back. Welcome to this new section on storage. In this section, we’ll be looking at the different storage options that are present in Google Cloud. We’ll be talking about block storage, file storage, and object storage options in this section. I’m sure you’re all excited. Let’s get started right away. Let’s get started with block storage and file storage. What is the difference between block storage and file storage? Think about this. What is the type of storage of…

Introduction – What Is A Website ? In this section we’re going to be talking about web application penetration testing. Before we can start talking about that, we need to understand what is a website. And just like I said before, a website is just an application installed on a computer. That computer probably just has better specs than your computer, but fundamentally it works exactly just like another computer computer. So it has an operating system and it also has a number of applications to allow it to act…

Reading & Writing Files On The Server Using SQL Injection Vulnerability In this lecture I’d like to show you how we can use SQL injections to read any file in this server. So even if the file exists outside the WW root, we’ll be able to read it exactly like a file disclosure vulnerability. And we’ll also see how we can use it to write files and upload them to the system just like a file upload vulnerability. So the first thing we’re going to have a look at is…

Discovering SQL injections in GET Okay, now I’d like to show you an SQL injection and then a different file and a different page. And I’ll show you a few different things that you can do to exploit that vulnerability. So the first thing I’m going to go to the login page which is in here, user info. So the first time we went to the login page from there, this time we went to the user user info page. So this page will show you the information about the…
