Computer hardware include CPU (central processing unit), main memory chip, main board, hard drive disk (HDD), monitor, keyboard and others. CPU is one of the most active components which conducts many kinds of operations, and it itself may pose many threats on security. Since CPU is usually manufactured by a few companies, and operates their only instruction set in a way that is not so public. They have enough reasons to keep it operating in this kind of secret way, for example, that is simply the business secrete.
However, from another viewpoint, since it's operating secretly, there are few people that really know how it operates, and maybe even fewer people know what its normal working status is, and whether it's operating in a normal way or operating in a harmful way. Maybe the CPU is almost always, say, 99% of time, normally, but its operating in another 1% of time may do any kind of harm, including releasing sensitive information that is usually not permitted, implanting virus codes / instructions, cleaning important data, and so on so forth.
Theoretically until we know all the secrete behind the CPU, we can imagine that whatever kinds of security threats can be introduced by the CPU itself, not to mention that there are so many other chip sets inside our computers.
Hi Li,
ReplyDeleteI really enjoyed reading your post. It is important to know how harmful that a computer virus damage both your home drive and communication. I like how you included the components of computer hardware, but I wish you could have added more detail for each of the hardware. Therefore, the readers will understand how each of them are operational to secure your computer from any threat.
The one suggestion in your post is to edit any grammar/sentence structure errors. Another suggestion is to define what “hardware security” is and give the depth of information about hardware security.
Keep blogging!
Hi Li,
ReplyDeleteVery nice work on your blog! It is a new knowledge for the hardware security problem to me. When I read “communication and security”, the first thing I thought is software security which caused by black hackers. Your blog is very detailed and knowledgeable. From your blog, I have learned that how the hardware impacts the communication security. I realized that, definitely, the CPU is the heart of computer. It does not only affect the speed of computer but also will threat the security of the computer
Hello Li,
ReplyDeleteYour blog post is interesting and informative. I really like how you decided to talk about hardware communication. We always tend to fix bugs in software and make it secure, but we also have to make sure hardware that we are using is secure because it is possible to have a very secure software, but running that on corrupted hardware will result in faulty product. I would like to suggest you to explain little bit more about hardware security. I think this topic is very interesting and people would love to read more about it. Overall, this post was a great read!

Hi Li!
ReplyDeleteYour blog post was quite interesting and informative. I actually learned something about communications and security hardware! Most of us do software end security since we are CS majors but I like how you talked about hardware. Since I work in IT, I deal with all sorts of problems and I found that having a hardware firewall is optimal for security rather than a software firewall. I would like it if the security aspect of your post were to be elaborated more. Otherwise great work!

Hi Li,
ReplyDeleteNice post on hardware security. Whenever we talk about computer security we generally tend to talk about software related security such as writing secure software, anti-virus/anti-malware software, etc. It is good that you chose to talk about hardware security instead. You gave a nice introduction about the hardware components of the computer. It would have been nice if you had elaborated a little more about how to secure our hardware. Also I would like to suggest you to use criterion before publishing your post. It really helps to catch all the grammatical errors. Good Luck!
Hi Li,
ReplyDeleteYou have some good thoughts about this topic. The CPU (and related components) definitely pose a security risk and companies like to keep their proprietary technology under lock and key. For example a few years ago, the Playstation Portable was hacked. People wanted to explore how it worked and run their own programs on it. But as a result of hacking it, people were also able to begin pirating the videos games that could run on it. As a result, Sony kept releasing both new software and hardware updates in order to keep their technology secure.
Please remember for your next article to include some more relevant research that your readers would be able to connect with. Thanks!
