휘파람

We recently studied about Physical Security. First of all, I did not realize how important Physical Security is when it comes to Information Security, I only thought of securing networks, ports etc. when we talk about information security. But this week, I am more focused on our Machine Problem, which is a Network Intrusion Detection System. For this we chose an open source software called Snort. At first glance, studying and running Snort seemed like rocket science, but after watching a few video tutorials, it made things a lot clearer for me. 

Ok so in the past two weeks, we mainly discussed two topics. Encryption & Decryption Access Lists For Encryption and Decryption. First off, what is encryption? Well, encryption is basically converting the message's content to symbols or characters that doesn't make sense, unless deciphered. I learned that there can be different ways of encrypting messages and files. In my opinion, encrypting your files can be one of the most basic, but still a highly effective method in securing your files from unwanted parties. It's not difficult to learn encrypting too! One of the other thing I learned this week is access lists. It's basically setting up restrictions in networks. In other terms, you can call access-lists "restrictions". For example, you can block access to certain ports, which in turn, would disable access and capabilities based on blocked port, you can also block a certain IP etc. I think setting up these access lists is a must for com...

This week groups mostly presented their take on their given whether they are pro or anti.  The topic I am most engaged in is, of course, our topic. It is about Internet censorship and whether the government should be given control of it, like in China. We (my group) oppose the idea, because the Internet is a powerful tool and nobody should be given control of it and its contents. The Internet in China is a perfect example of this, Chinese people practically only see things what their government want them to see and any statement about opposition to their government will be pacified quickly.  There are many other interesting and thought provoking statements made by the other groups on their respective topics. For example, Bitcoin rising as 'the' virtual money and legalities behind it.
