In the lecture 8, we keep on learning SNA especially the two
SNA examples about the PageRank and HITS. And we get some knowledge or concept
about the newly developed area of social network, that is to say, semantic web
in the lecture 9. We finally learned several kinds of security phenomenons or
problems of the social network in lecture 10. The knowledge of semantic web is
totally new to me. And I get to realize the importance of the security of
social network.
Security of the social network has become an increasingly
important issue nowadays. Then what the definition of network security is? Network
security consists of the provisions and policies adopted by a network
administrator to prevent and monitor unauthorized access, misuse, modification,
or denial of a computer network and network-accessible resources. Network
security covers a variety of computer networks, both public and private, that
are used in everyday jobs conducting transactions and communications among
businesses, government agencies and individuals.
I have just read a news about it. It’s in Chinese.
社交网络安全问题严重
北京时间1月6日 消息，据外国媒体报道，ZoneAlarm最近发表一份安全报告指出，目前Facebook上的垃圾信息问题严重，超过20%的链接为病毒。
ZoneAlarm在近期发表安全报告中指出，Facebook目前每月拥有8亿的活跃会员，其中超过400万人会被垃圾信息骚扰，更为严重的是，在Facebook的所有连接中，超过20%的讯息链接是病毒。
据了解不久之前Facebook上就广泛流传“2012 世界末日预言”和“全智贤撕裙广告”的图片，但是这些都是恶意应用程序，在用户点击进去之后，该应用程序就会自动在用户的页面上自动分享，是用户成为垃圾信息的发送中心。
近期国内也出现了中国互联网有史以来波及面最广、规模最大的泄密事件。去年12月21日以来，CSDN、天涯、人人网、世纪佳缘等多家网站被曝遭到黑客攻击，包括密码等大量用户数据库被公布在互联网上，引发广泛关注。一时间，修改密码成为网友的头等大事。
随着社交网络的快速发展，由于社交网络账户中包含着大量的用户个人信息，其中包含着巨大的商业价值，而使其成为黑客攻击的新重点目标。
建议用户加强自身的账号安全意识，不使用未经授权的可疑应用程序；采用安全性较强的密码；不接受未知朋友的邀请；不点击可疑链接；注意识别朋友分享的信息与状态。
Perhaps the related laws should be set and technical
methods of the website must be taken. But in the aspect of the users of the
social network. Here is some tips.
Be careful with your password. Do not enter the
password on another website without checking. The website can also be one
phishing sites whose targets are your Facebook, Twitter, MySpace, Renren, Weibo
accounts.
Be careful with the third-party application. Try to
make sure the application is not a virus or something before you give the
authorization to it.
Do not click on the links strangers put on your
comments without checking. Some viruses may be installed on your computer
without your attention while your clicking.
Since it is already an information age nowadays,
perhaps we should relax and enjoy the happiness the social network can bring to
us after we ensure that we are not one of the victims or disseminators of
viruses or malicious plugs.
If you want to learn more tips about the security
of the social network, you can watch the following video.
As you have mentioned in your pages, we admit that the regulations and related laws should be set by government to supervise social network websites to protect users’ privacy. But the most urgent thing may cultivate users’ awareness, I reckon. What do you think? Do you have some suggestions on popularizing this sense?
回复删除I suggest a way to improve users' awareness to protect themselves. Threaten always work to remind people to protect themselves. Perhaps more bad news about the attack of the social network should be broadcasted and propagated. And people will realize the possible harm. After hearing the news about the possible harm, people will realize which kind of information or news will be used by those bad guys. After all, practical things are always easier to be accepted than theory.
删除Apple and Google also have made some mistakes on security: their Android and iOS password has been easily cracked by a Swedish security company, Micro Systemation. All the users' data, including GPS geolocation, files, call log, contact log, short message, even the button record can be extracted from devices through their software. So we should be very careful about our smart phone.
回复删除Yes, I am quite agree with you! Besides, I would like to learn how to make a website as you do!!!
删除I just studied to build a website less than 2 month, I also get started. If you want to study it, at first, I suggest you buy a domain and lent a sever space, than learn with doing. Choosing a suitable platform will reduce too much work and difficulty.
删除Yes, thank you very much! I will take your advice.^^
删除strongly agree that Security of the social network has become an increasingly important issue nowadays. take social networking website facebook as reference, it have some password protection and login protection, i have try to login in another public account, they will ask you a series of questions such as ask you the name of your friend, I think it is a good features, also, it will send email to inform you. apart from the facebook security features, i think the most important is self awareness, user should remember log out and re set password in a period.
回复删除Yes, more security methods have been applied to social network which is really a good phenomenon. And I always believe that the social network will surely become a secure and harmony place in the future.
删除Hi, I saw your video, and I thought it is indeed helpful. If we can do all those regulations right, the cyber attack may not be that hazardous. However, it is too difficult for us to take care of them, especially on a social network platform. I mean, when you use your Facebook, you believe your friends, so all your post on your wall is your real life. It seems like information security and social network platform is a pair of contradiction.
回复删除Yes, that's always a problem. But different people will have different choices. Just do what you want to do and take responsible for yourself. I think that's would be fine.
删除YA. I have read some more practical ways. You can read this.

Yes,I often use the social network such as renren.com and encountered many cases that the web was attacked by hacker. For example,some parts of the webpage may be suddenly lost. That may be harmful to reveal of our private information. And I am always following some tips about the social security. So we should pay attention to our own action and protect ourselves. Even if some website was down, our information is safe as long as we don't leave something important on the website.
回复删除You have a high safety awareness when you enjoy yourself on the social network. I have learned more from your comment. Thank you very much!
删除These tips are very useful tips for us to maintain the good social networking environment. Although we could not avoid these security issues at all, in my opinion I believe that there are also a lot of methods we could take to decrease these damages.
回复删除Yes. I have also read your blog on this topic. I think they are more practical than those above.^^
删除In fact,sometimes we can recognize some unfriendly emails by ourselves trough watching address and using software to detect the attached application.Some unfriendly emails are easy to find out without clicking into.Some mail servers now can automatically help us to filter those emails.
回复删除Yes. That's really a good technical method to ensure security. We often forget to check whether the attachment is secure or not when we read the emails.
删除right, participant should really know about the user agreements and disclaims when joining a social network. You know the social network is different from a hk golden forum, actual data and information is present on a OSN. Therefore, people should definitely be more alert and educated about the use of social network, a people has to follow laws in a actually reality, same as a participant in the social network, they should follow some guides or rules too.
回复删除Yes. I am quite agree with you.
删除Hi, As long as there is valuable information on social networking, which it always has, there will be serious security issues. I think from a system perspective, the reason has its relation to the distributed nature of social networking and the larege scale of network it involves.
回复删除Yes. I also think that it is one of the reasons.
删除Many business organization will block social websites in their office because they're afraid the their staff will leak important information unconsciously.However it is not a good practice because social network is also a powerful source for business.
回复删除Well, the social network does contain too much information of users before it has a security mechanism strong enough to protect users' privacy. Therefore I advise not to put too much personal information on it to prevent "Human-flesh searching" by others.
回复删除privacy is so complex thing that technology and law can't protect it completely.The most important protector is the users themselves
