Aside from the Group 2’s Presentation 1 last January 7, the Group 3 reported their Presentation 1 as well about the Information Security: Threats and Trends. What I will be sharing here are from my notes and some researched terms.

Information Security, sometimes shortened to InfoSec, is the practice of defending information from unauthorized access, use, disclosure, disruption, modification, perusal, inspection, recording or destruction. -Wikipedia

Primary Goals of Information Security:
-Confidentiality – the protection of personal information. -Google
-Integrity – the quality of being honest and having strong moral principles; moral uprightness. -Google
-Availability – the quality or state of being available. -Google

Threats – possible danger that might exploit a vulnerability to breach security and thus cause possible harm. -Wikipedia

Current Threats:
-Caller
-Crytolocker

Common Threats:
-Bot
-Malware
-Virus
-Worm

Phishing – the attempt to acquire sensitive information such as usernames, passwords, and credit card details (and sometimes, indirectly, money) by masquerading as a trustworthy entity in an electronic communication. -Wikipedia

How to prevent the threats?
-Security Policy
-Security Awareness
-Access Controls
-Identification
-Authentication
-Authorization

About the Trends, I wasn’t able to take down notes because the words in the powerpoint were too long and the reporter just read their presentation. They did not have a game. They just had a quiz for us. So if I will rate their reporting 1-10, I would rate them 6.

Green Computing

The Group 2 already reported their Presentation 2 about Tile App last December 15, 2014. They reported their Presentation 1 last January 7, 2015. So this blog is all about the Group 2’s Presentation 1 which is the Green Computing.

Green Computing is the study and practice of environmentally sustainable computing or IT. -Wikipedia

Green Computing is also called Green Technology. It is the environmentally responsible use of computers and related resources. Such practices include the implementation of energy-efficient central processing units (CPUs), servers and peripherals as well as reduced resource consumption and proper disposal of electronic waste (e-waste). -TechTarget: Search Data Center

I cannot remember every detail about the reporting they had. So, what I will be sharing here are the things I have noted when they had their reporting. This is just a few so maybe I’ll have to research on the Internet for more infos.

They talked about ways for Green Computing. One of those is the Power Management which is a conservation of power. Another way is the Server Virtualization which is known as VPS and it is used to split server. The advantage of it is it reduces the number of servers. The disadvantage is the implementation can be a major hurdle. “Hurdle is an obstacle or difficulty.” -Google. The other ways are the Efficient Recycling or E-waste and Telecommuting.

The reporters were too fast so I had a hard time copying for notes. So if you want to know more about Green Computing, I have found a blog that talks about it. Just click this.

In our ICT173 groupings, each group was assigned to report 2 topics. The first topic was provided with our teacher which will be the Presentation 1 and the second topic should be about a gadget or technology that is not familiar to the public and it will be the Presentation 2.

The Group 1 already had their Presentation 1 last week. So last Monday, December 15, 2014, they reported their Presentation 2 about the NVIDIA Shield Portable. Even though I am not into gadgets, it still amazes me that I have never heard this gadget before. Well, maybe because this gadget is for gamers, and obviously, I am not a gamer.

But to let you know about this gadget, I have researched some of the information about it…

The Shield Portable is a crossover of a handheld game console and mini tablet computer by Nvidia, released on July 31, 2013. -Wikipedia

IT Careers and the Global IT Talent

1

Today, December 10, the Group 1 had their reporting for Presentation 1. Their topic was about IT Careers and IT Global Talent. Their presentation was boring but quite interesting since it was well explained at the last part of their presentation. And also, I think there is a need for us to pay attention because they will be giving a quiz afterwards. I guess nobody doesn’t like to receive a zero score on their quizzes.

So if we are going to talk about IT Careers, our world nowadays has so many jobs to offer. There are also so many careers that you can choose from, such as being a System Analyst, Systems Administrator, Support Specialist and so on. But the question is, do we have the skill or the talent that can reach to the company’s expectations?… Here in ICT (Information and Communications Technology) in the USC (University of San Carlos), they mold us to become the best persons in the IT Industry. They want us to enhance the skills and talents that we have or acquire it through learning. Skills can be acquired if you are just willing to learn. Talents are inborn and you will just have to develop it more. The Group 1 also state the Pros and Cons in being in the IT Industry. I can’t talk much about what they have reported ’cause the info they have given to us wasn’t able to retain in my mind.

After the reporting, they gave the quiz through a group activity which is raising our illustration boards for our answers. Luckily, the questions were easy and our group was able to answer the questions correctly. Thanks for our teamwork and the attentiveness we had during the Group 1’s reporting. Our group, the Group 6, was the highest. We got 10/11, other groups got 9 and 8. Not bad!

I think that’s all for now. I badly need to publish this and send the link to our teacher. ‘Til next time! 🙂
