Three ways networks become vulnerable can be due to outdated software, using the hardware outside of the preferred network, and compromised usernames and passwords (Pioth & Pioth, n.d.). Outdated malware or antivirus software doesn’t have updated security protocols and can be vulnerable as a result. In many cases employees use their company issued machines outside of the office & inside of internet cafes, coffee shops, etc on wireless networks that are less than secure which leave them wide open to cyberattacks. Lastly compromised usernames and passwords are a result of people writing them down and leaving them in insecure areas, or creating weak, easily decipherable passwords.
As a result of these vulnerabilities, three ways to protect your network infrastructure would be to;
1.) keep software, malware & antivirus definitions up to date.
2.) utilize encryption and strong secure network connections, as well as VPN, or virtual private network connections when outside of the office on company devices.
3.) Implement stronger access control features and MFA, or multifactor authentication when accessing the network.References

Beautiful devotion this week. Phil. 2:6 tells us that even though Jesus was in the form of God, he didn’t think it was robbery to be equal with God (James, 2019). This speaks to his humility. Jesus was born in humility, without the notoriety of any other king, but just as sure as He is king, He is God. He was born all man and all God. Not only is He all God, but even though he came in humility when it came to fulfilling the mission in which His Father God sent him to fulfill, He came with power and authority. Forgiveness is what separates Christianity from practically every other major religion. I am so grateful for his forgiveness of my sins on the cross and the unmerited grace he has given. Not only did he have power as a God to heal, but he also had the authority & power to forgive sins and he did this on multiple occasions to prove to the detractors who He was. Thank you Jesus for your saving grace!

Great job Cameron. I chose desktop virtualization as well, but it is awesome to be able use it while also building video games. Great job on storage virtualization as well. Not sure I would have used it for game development for the reasons you listed, but glad that one of your data was compromised.
Safe Mode and Safe Mode with Command Prompt are both good options. Event Viewer with Reliability Monitor is a good pick for the ability to track logs and application errors. Being able to effectively read logs and errors is half the battle, but will go along way in being able to troubleshoot Windows issues effectively.
Two types of virtualization are server virtualization and desktop virtualization.
One of the pros to server virtualization or a cloud server would be you don’t need to have a dedicated space for a server onsite or on location at your organization. This is cost effective, efficient, offers flexibility and is scalable as you can add to the servers as the company expands. Some of the cons might be the initial cost involved, and possible security concerns over the server not being onsite.
Desktop virtualization or VDI, while already used became even more heavily relied on during COVID. Some pros once again might be the cost effectiveness as you can PCs with less powerful specs to run the VDI session. Another pro is enhanced security as all security and policies are protected centrally. Some of the cons are the upfront cost involved with hardware and software and VDI licenses. Also you can run into performance issues with bandwidth and latency causing lag and slow responsiveness which I am experiencing on a daily basis in my current role.
The two methods for troubleshooting in windows I will speak of is command line tools or prompts, such as pinging a network connection, or traceroute to trace the path of the network/ router you are trying to reach, pathping, etc. These can be used if the printer is booted into a Safe Mode environment as well.
The second method for troubleshooting slowness in Windows would be Task Manager. You can check the process of each application running on the machine and enable or disable them, also you can check the performance and see when the CPU is overclocking or the memory is bottlenecking. Performance in Task Manager allows insight into indicators for potential components of the PC or laptop that might need upgraded such as memory or hard drives.
I love this passage. I think in another synoptic gospel it names the centurion as Jairus, but the faith displayed here is remarkable. It is fascinating that Jesus said in all Israel he hadn’t seen such faith. These are His people, the people who were supposed to have had the market or real estate on the one true God cornered, so if anyone should have had faith it should have been them. Much the same, since we are the body of Christ, and serve the true and living God it is interesting how we can have faith in the area of healing, but lack it in the area of finances, or job promotion. I think many things are a result of people not knowing, speaking and hearing the word. If we don’t know what his word says about Him becoming poor, that we thru His poverty might become rich, we can’t speak it, or believe it and the word tells us faith comes by hearing & hearing by the word of God, so we need to keep the word before us, in our mouth and believing what we speak when we hear it. We have to be like the centurion & whether or not someone prophetically comes to us, or picks us out in the congregation, or on the street to say speak a word over us, we have to be able to speak the word of God over our own lives and agree with the Holy Spirit in faith that God will do just what His word promises us today. Jesus said blessed are those who don’t see & yet still believe. I trust God to do exceedingly and abundantly above all we could ask or think, so any area that is lacking in my life I am praying with a spirit of expectation that God will prosper me in every area of my life even as my soul prospers. And I pray the same for you as well.
Well, from what I’ve read UDP is used in instances where speed is valued over reliability and in instances where an occasional dropped packet would not cause too much concern. A real life application where UDP is used in lieu of TCP/IP would be VOIP phone systems, and also video/online game streaming (TCP Vs UDP: When to Use Which Protocol | Twingate, n.d.).

PAN’s have an area of 20cm from the person according to the lesson I believe. It really aides in allowing you to visualize how large or small these network may be.
Great job Carlos,
TCP/IP is still said to be the dominant protocol when it comes to internet standards. UDP is faster, but less reliable according to the lesson. I wonder what other potential protocols might be emerging that could someday surpass TCP/IP as the common standard in the near future?
Great Post Misty,
I don’t have much knowledge of Content Delivery Networks, or Storage Area Networks, but very good information. From what i read, it appears most of the other networks previously described share communications and resources across a common area, local , metro, campus, etc, while a storage network is a dedicated high-speed network that connects to servers with storage space allowing for a centralized storage space. A CDN is a mass of distributed networks across the globe designed to deliver content quickly, regardless of location in effort to reduce latency. Thanks for allowing me to obtain new knowledge.
TCP/IP is two separate internet protocols that work in conjunction to ensure data is transferred securely across the network.
TCP stands for Transmission Control Protocol. This is a communication standard that enables devices to transmit messages. The protocol makes sure that packets are securely sent & received across that network.
IP stands for Internet Protocol. Since every device that connects to the internet has to be assigned an IP address, this protocol defines how devices and other applications transmit or exchange these packets of information/ data. (What Is TCP/IP in Networking? | Fortinet, n.d.)

The different classification of networks are WAN, LAN, CAN, MAN, and PAN.
I will start from the smallest and work backwards, so the PAN is a personal area network, used for near field communication devices, such as RFID, NFC, Bluetooth, etc. It is primarily used for things within the immediate vicinity of the person as the name would imply.The LAN is probably most commonly used or known. This is your local area network. This is the network used in your home or office to connect all devices on you network.
The CAN is a campus area network, and generally is meant for interconnecting network devices within the campus area.
A MAN is a Metropolitan Area Network, which I had never heard of prior to this class, but is said to be used in the metropolitan area of a city or cities, defined as larger than a Local area network, but smaller than a wide area network.
Finally, we discuss a WAN, or wide area network, which interconnect network devices over a large area, connecting many local area networks to the larger infrastructure. It allows users to communication across networks to share data, print, transfer files etc.
I like to think I am a good blend of both patience & judgment, although I have heard from my immediate family I am less patient with them at times and more critical compared to those I minister to or deal with. I own that and have been trying to actively work on it, however I do feel it is only human nature that you come to expect more of the people you are closest to & therefore are more expressive or demonstrative when it comes to their shortcomings simply because you know what you have poured into them. The time and effort Jesus poured into the disciples in the 3 short years they followed Him, when Peter tried to discourage Him from fulfilling His calling on earth, he literally called him Satan in sharp rebuke (KJV, 2019; Matt 16:23).
But keeping in focus this weeks devotional, I think it is important to not only ask your peers and those close to you for their honest perspective regarding how they see you at times, but also in your alone time with God, we should be like David in Psalms 139 “thou hast searched me and known me.” There is nothing about us that God doesn’t already know & if we spend time in prayer, He will reveal to us our shortcomings if we are willing to be honest with ourselves. I think it goes a long way in teaching us humility. He chastens whom he loves, and gives grace to the humble, but resist the proud. Rom. 12:3 also reminds us not to think more highly of ourselves than we should. This will help us to remain humble, but also compassionate knowing none of us were born perfect, and we are all striving to be made into that perfection in Christ Jesus.
Finally, when we aim to help others rather than ridicule or tear them down, we are building up the body of Christ as iron sharpens iron.

Great post Isabelle. While I have used Googles Suite of applications (Docs, Sheets, Slides) before that are alternatives to Word, Excel, PowerPoint, etc, I haven’t used Files by Google that much. I guess my question would be, were Google applications designed primarily for Android OS or primarily as cloud applications for multiple OS as they are used on Windows computers as well? I have used Macs a few times as well, and while Microsoft has designed Office for Mac I have never used any Google applications on a Macbook either, is this possible?
