sql injection – How would a beginner test security systems?

I’m a beginner on course to be an expert (hopefully) and I’ve been set assignments to test security systems on the web. The whole assignment is to prepare, test and document the results to correlate with real-life professional work. Coming from a software development background, I am logically solid on information security systems and how they work but I struggle with the practical side.

The assignment is to prepare and to pentest a log in form by SQL injection. I also have a background in website development but never understood the backend of things. What would be the best way to develop a login form with a backend database that’s susceptible to a sql injection (I’m a rookie so the easiest and most vulnerable login form would do)?.

Would I need a CMS? (This would all be in a sandbox environment)
Would I need a server for SQL?

I apologise heavily if this is very plain and makes you cringe.. but help would be great!

unity – How can I render 3D objects and particle systems in front of a Screen Space – Overlay Camera?

To render 3D objects on top of your canvas:

  1. Create a new Canvas in Screen Space – Overlay.
  2. Add a RawImage to that canvas.
  3. Create a new Render Texture.
  4. Add the Render Texture to the Raw Image.
  5. Create a new Camera.
  6. Set the camera to Solid Color background with an alpha of 0.
  7. Set the output texture of the camera to be the Render Texture you created.

You can now render 3D objects on top of your canvas; however, there are extra steps for particle systems:

  1. Create a material. Set its shader to Universal Render Pipeline/2D/Sprite-Lit-Default.
  2. Add your particle sprite to the Diffuse of your material.
  3. In the Renderer settings of your particle system, replace the material with the one you just created.

You should be good to go!

(If you have any problems, try going to your Render Settings and change the Anti Aliasing to 8x.)

Operating systems memory management: help understanding a question related to segmentation

There is this question in my textbook (Operating Systems: Internals and Design Principles by William Stallings):

Write the binary translation of the logical address 0011000000110011
under the following hypothetical memory management schemes, and
explain your answer:

a. A paging system with a 512-address page size,
using a page table in which the frame number happens to be half of the
page number.

b.
A segmentation system with a 2K-address maximum segment size, using a segment
table in which bases happen to be regularly placed at real addresses:
segment# + 20 + offset + 4,096.

I am having trouble with understanding part b. I’m not a native English speaker. Initially, I assumed that “using a segment table in which bases happen to be regularly placed at real addresses” means that the segment number in the logical address is the number of the physical segment, but then I read this “segment# + 20 + offset + 4,096”, and I am not sure what to make of it. So does this mean that the base number in the segment table contains segment# (in the logical address) + 20 + offset (in the logical address) + 4,096?
