Christopher Molina Prof. Kelley ITN 260 11/04/23 Module 04 Project | Endpoint and Application Development Security Case Project 4-4: UEFI UEFI (Unified Extensible Firmware Interface) is the startup hardware/software that controls how your system is set up which can hold partitions with more than 2 TBs and are quicker than BIOS. Can also use a Graphical Interface with animations and mouse support to properly modify it accordingly. Made to simplify the booting process, prevent the injection of dangerous code. It can also support 32 0r 64-bit processors as well. As part of the security process, it is important to enable UEFI for the startup process as it can help to prevent any cyber-attack even from startup. There are many advantages of UEFI that can be talked about and are well known. One of them is that overall, it is a faster booting process than BIOS, can support larger hard disks and partitions in comparison to its predecessor, Boot mode security, and it looks better than a blue screen with few options. Another interesting thing is the with BIOS you would have to manually change hardware and now UEFI can control it like the brain stem in a human being. Most of these things are for the betterment of the Technological world. Just as there are pros there are also some disadvantages for UEFI like the fact that it is more complicated than BIOS in the set-up process which could affect developers or designers, for certain features you need to change into Legacy mode, does not support HDDS with an MBR layout, and to work properly the hardware & operating system must support the specific specifications. Another disadvantage is that it isn’t compatible with older hardware & software. It is important to look at the cons as well because there must be a balance between the advantages and disadvantages. Overall Id say there is more love than hate for UEFI over Bios but there are just a few criticisms like the fact that it uses FAT 32 for its overhead which isn’t necessary for a 32-bit operating system. Another thing that is of concern is that it is too controlled by the OEM manufacturer. However, all in all I’d say that UEFI is better than BIOS for the simple fact that it’s efficient, quick, and easy to learn. Regardless of your IT experience it can be configured in a way that isn’t too complicated. Personally, I think the Graphical Interface that it has is amazing not only for its functionality but also how it looks. Something else that stands out to me is the amazing memory that can range up to 9.4 ZB that’s right ZB instead of TB. For these reasons I believe that UEFI is one of the best boot up systems in the cyber world. References: (n.d.). Boot to UEFI Mode or Legacy Mode.
