Week 6 - BSIT380-T303 System Hardening and Network R - How to protect data using hardware-based security.

    As digital threats become more sophisticated, relying solely on software-based security measures isn’t enough. Hardware-based security offers an extra layer of protection by safeguarding data at the physical level. One of the most common hardware solutions is the Trusted Platform Module (TPM), a chip that securely stores encryption keys and sensitive data, protecting it even if the hardware is stolen. TPMs can be used for disk encryption, ensuring that data remains encrypted and inaccessible without the correct authentication. Another key tool is Secure Boot, a feature that ensures only trusted software loads during system startup, preventing malicious software from gaining access to the system. Additionally, hardware security keys, like YubiKey, offer robust two-factor authentication by using cryptographic keys to ensure only authorized users can access critical systems.

    Hardware-based full-disk encryption solutions, such as self-encrypting drives, encrypt data directly on the device, reducing reliance on software encryption and improving protection. Hardware firewalls also provide stronger defenses by operating independently of the system, guarding against external threats. Lastly, biometric hardware like fingerprint scanners or facial recognition adds another layer of security, ensuring that only authorized individuals can access data or devices. By integrating hardware-based security solutions, individuals and organizations can establish a multi-layered defense system to safeguard sensitive information from ever-evolving cyber threats.

Week 3 Posting - RAM Making Your Everyday Tasks Easier

          Random Access Memory is your computer’s short-term memory, unlike the long-term memory with a hard drive or SSD, RAM stores date temporality while your computer is running. When you open an application or a file, your computer loads it into RAM for quick access. This allows your computer to do tasks faster because accessing data from the RAM is much quicker than fetching it from storage. The more RAM you have the more applications and data your computer can handle without slowing down. RAM is good for multitasking, gaming, video editing, and resource-intensive tasks. In conclusion, RAM is kind of the unsung hero of your computer, enabling it to handle tasks swiftly and efficiently. Understanding its significance can help you make informed decisions about upgrading your system’s memory for a better computer experience.

Week 5 Post - Cleaning Your Windows 10 Machine

               It is very important to keep your Windows 10 machine; and we are not talking with Windex. You want to keep your PC clean, and I am going to tell you how to keep it clean and make sure you keep all of your important data. First off you want to start by backing up all of your important data; you can either use a external hard drive or one drive, I would suggest an external hard drive then you have a spare copy of your data incase your computer crashes. Next up go through the programs you are not using anymore, and fully install and delete those. Another good way of cleaning up your PC is clearing the temp files, or temporary files, these can be found by searching the C: drive. Up next you want to run any updates you need; this will boost your performance and make run things smoothly. Then you can put your data back on you computer and organize it to your liking. There are many ways to clean up your PC this is just a process I run...

Week 1 - BSIT220-T301 Network Mgmt & Infrastructure

                  This is my 2 nd blog I have done, and my 13 th blog post I have ever done, did one a week in my previous class here at Bellevue. I would say I have some knowledge about the Network+ and Network models from my previous college. At Southeast Tech we got to work on all sorts of network equipment and troubleshoot it as well. We worked on servers, routers, switches, access points, and more. We got to build networks on server racks and ping and use all sorts of commands, so I have a nice background with information, and I am excited to learn more about that as well as the Network+ certification and what it takes to get that.
