  關于安全意識的英語美文篇1

  Internet is the place where we spent most of our time. We are now dependent on the internet for almost everything. We connect with friends and family through social networks, shop online, have fun and do serious works using the internet. However, internet is not a safe place anymore. Bad guys are trying to steal our identities and harm us. Sometimes our identities are being sold to other companies without our knowledge. When we visit any website our identities get exposed through IP address to the website owners. You should be very careful what you share on internet. Because once you share any sensitive information it becomes almost impossible to completely delete it. Becoming completely anonymous on internet may not be possible but you can hide your identity to some extent by following some basic tips.

  Hide your online identity

  1. Hide IP address:

  Internet protocol address or IP address is our identity to the world when we are online. Every device connected to the internet has a unique IP address assigned by internet service providers. When we visit any website or access anything using internet our IP address gets exposed. Some websites even store all details in their log files. IP address can reveal geographical location and some other information about us. We should hide our IP addresses in order to conceal our identities. There are several ways to hide IP address; you can either use proxy servers or use some software which will fake your IP address. Virtual Private Network or like Cyber Ghost can be used for this purpose as well.

  2. Fake your identity

  Yes, you read it right. If you want to be completely anonymous online, never use your actual name, date of birth or address on the internet. Instead take a disguise; select a fake name, address and other related information when creating any online account. In this way you can safeguard your actual identity. Some sites like Google requires phone verification when opening a new account. I’ll recommend you not to use these sites if you want to completely hide your personal information. However, keep in mind that providing incorrect personal information may have some legal issues.

  3. Stay away from social networks

  Social networks like Facebook, Twitter, Google+ have become a part of our daily life. It helps to stay connected with friends and family. But when it comes to identity theft, social networks are soft targets of hackers. Sometimes we share sensitive information and photos unknowingly. If you are already using social networks, then delete your all existing social network accounts. So if you want to be an anonymous, don’t ever use any social networks.

  4. Don’t use Google services

  You should not be using any Google services if you want to be anonymous. Don’t perform a Google search or watch YouTube videos when you are logged into your Google account. Google stores all these activity and maintains a database of your account which can be accessed by visiting www.google.com/dashboard.

  5. Setup your own e-mail server or use disposable email address

  If you have little technical knowledge you can buy a custom domain name and setup own email service. We know that Google reads our emails for providing contextual advertisement. It is always a better idea to use own email service rather than relying on any 3rd party email service providers. Alternatively, you can use disposable email address when signing up on websites that requires registration. In this way you can protect yourself from unwanted spam mails and hide your actual email address.

  6. Disable cookies in browser and use private browsing mode

  Cookies are used for different purposes. It keeps a track of all websites visited, saves their log in credentials, etc. Advertising networks like Google AdSense serves targeted ads based on cookies. I’ll recommend to completely disabling cookies. You can do that by going through options in any modern browser. Private browsing mode can be used to make our browsing details secret from others.

  I think if you follow the above mentioned tips you can hide your identity. Don’t forget to use good antivirus software and regularly update it. Enjoy your online life!

  If you know any other ways to protect online identity do share with us.

  Twitter was recently hit with a security problem when the website was hacked, leaving a quarter of a million accounts in limbo. Weeks earlier, Zappos suffered the same issue. These are examples of how even the strongest passwords can be at risk. However, being the Internet users we are, we aren’t just going to pack up our digital lives and forgo the Internet altogether.

  We must improve our current password practices and ensure that the day-to-day scammers and hackers don’t find the key to our online lives. Today, I present you with the comprehensive guide to everything about passwords. From how to choose a strong password to what to do afterwards.

  Password Boot Camp

  What better way to start a guide to passwords than by helping you create the ultimate password? To start, have your computer near by along with a writing utensil and a notepad- they’ll come in handy during this process, and are all that you’ll need. No need for dictionaries or a second individual—your password doesn’t have to be, and shouldn’t be, complicated and highly complex. Below are a couple of tips on how to get started:

  1. Make Personal Passwords Non-Personal - One key tip is to ensure that your password is related in some way to you that will be easy for you to remember, while not including easily identifiable information. What does that all mean? Yes, you can work in your favorite color or television show into your password. However, don’t include your address or birthday in there.

  2. No Random Generators – Password generators are always considered recommended for choosing strong passwords, but I always advise staying away from them for two reasons. First, some generators heavily reuse password suggestions. Secondly, they are much harder to remember and will require to resorting to password recovery frequently.

  3. Break the Molds - I advise not making use of real words or phrases in your password. For example, if you are going to include the word “soccer” in your password, use “

  2. No Random Generators – Password generators are always considered recommended for choosing strong passwords, but I always advise staying away from them for two reasons. First, some generators heavily reuse password suggestions. Secondly, they are much harder to remember and will require to resorting to password recovery frequently.

  3. Break the Molds - I advise not making use of real words or phrases in your password. For example, if you are going to include the word “soccer” in your password, use “$0kr” instead. This also means, don’t make use of dictionaries in consulting your next password—that’s just asking for hackers to come to you like fresh bait.

  4. The NAC Philosophy – The philisophy I just created while making this article is the NAC philisophy. This means ensuring that your password includes “Numbers A Characters” along with text. One common mistake with passwords is only including letters, but also including characters and numbers strengthens your password. Simply changing “LuvToPlaySoccer” into “!Luv2ply$okr!” turns a weak password into a strong one.

  5. Utilize the Strength Test – Finally, making use of a strength test can ensure that your password is top performing. Several online resources, including How Secure Is My Password, allows you to instantly see how strong (or common) your password truly is.

  Divide and Conquer

  It’s important to have a different password for each service that you use. It seems a bit difficult in the beginning, but when you begin to continually use the separate passwords for the separate services, you will find yourself associating one password with the service that matches it.

  When you use a separate password for each website, make sure that you don’t simply leave out a letter or include an extra number—that’s not considered a true variation, and truthfully, it helps narrow down the hacker’s choices even more. So how do yourself to remember all of these passwords? Making use of applications for your desktop or mobile device is a huge help.

  I highly recommend Passwords Plus or KeePassX. Both services are cross platform, have high encryption protection, as well as support for saving the passwords and codes of various services that you use. LastPass is another well rounded password manager that I recommend for users to make use of.

  Secrets In the Details

  You have a great password, wonderful. Now what happens when you forget your password? No problem, just go to password recovery and answer a few questions and you’re done, correct? Well this “convenience” is more of a convenience for hackers than yourself. Many times, when asked to create a recovery answer to a question, we always pick the easiest ones to answer to quickly get through the process.

  However, if your hacker already has the password to your email and is looking to extend its reach, they will make use of your easy-to-answer recovery questions to increase their control over your personal life. How do you protect yourself from hackers passing the recovery test?

  Answer questions truthfully but in a way that isn’t technically the norm. In other words, look to your recovery answers as passwords of their own. For example, if your question is “In which city were you born?” and your answer is Los Angeles, consider going a step further and including the state as well (even when asking for just a city), or spell the city in a different way, like *Lo$$ Angele$* instead of Los Angeles.

  A friend I consulted while creating this article mentioned a final tip: create an email address specifically for recovery. It may seem like a hotbed of all of your passwords, in one place, but if you ensure that you use the recovery only when you need it and emptying out your trash each time you make use of the password, an individual who hacks that email will be presented with an empty inbox—forcing them to target their prey elsewhere.

  Special iOS Consideration

  Finally, what’s the deal with iOS passwords? It seems that your FBI, secret spy, creative password production ends at this point. Most iPhone, and mobile users in general, seem to resort to simple passwords for their phones. This is worse than doing so for your social network, for example, because there is a greater likelihood of someone going into your phone than hackers in your website or services.

  This could be because our idea of hackers is a bit distorted: from the teenager in a dark room trying to crack password codes, to your nosy friend who’s trying to go into your phone to take a peak at your text messages, both individuals are considered hackers. Chances are you’ll encounter the friend situation much more often. Below are a couple of quick tips on creating the ideal mobile password for iPhone users and how to increase your security even further:

  * Avoid Patterns: With only 10 numbers to your disposal for only four spots, it’s important to not have corresponding numbers used in your code. This means that 1234 is out, 0987, is out, and the like.

  * Match Numbers with Letters: You may not have noticed, but the keypad on your iPhone also has letters associated with the numbers, also known as T9. This makes it easier to associate a mini phrase to numbers. For example, RAYS = 7297 or WANT = 9268.

  * Look into Longer Passwords: iOS also allows you to make use of text passwords as well. Going into Settings > General > Passcode Lock > turning off “Simple Passcode” makes this happen. Make sure you abide by the tips mentioned in this article when going by this route.

  * Limit Access from Lock Screen: In the same settings area, you can also change what you allow access to when locked. You can prevent Siri, Passbook, and Reply with Message to be accessible from the lock screen. You can also erase iPhone data after 10 failed passcode attempts from here as well. However, I recommend against using that unless I’m traveling or in a compromising venue (a concert, for example).

  Smart appliances and devices connected to the web, the coming Internet of Things, will be like Americans planted bugging devices in their homes. The CIA is looking forward to such an opportunity for mass monitoring. In the not-too-distant future, household appliances and web-connected devices will offer the government unfettered access to spy on citizens.

  You know how sometimes you hunt for an item that you have misplaced? A really cool aspect of the 'Internet of Things' could allow you to ask, What did I do with my remote control? The computer could tell you precisely where it is. What did I do with my book? You might get an answer like, It's at Tom's house on his coffee table. Now think about the bigger picture and combine the Internet of Things with smart meter data. What time does your alarm wake you up? When do you turn on your TV and the lights in various rooms of your house? How often does your doorbell ring? Individually these pieces of information may not seem overly important, but connect to the dots and it gives a very detailed snapshot into your private life. In the not-too-distant future, household appliances and web-connected devices will offer the government unfettered access to spy on citizens.

  Web-connected gadgets will 'transform' the art of spying and the real kicker is that Americans will willingly bug their own homes. "CIA Director David Petraeus cannot wait to spy on you" through your smart appliances, according to Danger Room. Petraeus spoke about the coming "Internet of Things" at a summit for the CIA's venture capital firm In-Q-Tel. "Items of interest will be located, identified, monitored, and remotely controlled through technologies such as radio-frequency identification, sensor networks, tiny embedded servers, and energy harvesters - all connected to the next-generation internet using abundant, low-cost, and high-power computing. The latter now going to cloud computing, in many areas greater and greater supercomputing, and, ultimately, heading to quantum computing."

  Previously "dumb" appliances will be replaced with "smart" energy-efficient appliances. Microsoft showed off the Home of the Future and studied smart homes. All of those location-aware apps that remotely control your smart home will also be sending "tagged, geolocated data that a spy agency can intercept in real time." Mobiledia reported, "Google is working on getting smartphones to work like remotes for home electronics, using near-field communications, or NFC, technology so devices communicate directly with one another as part of the 'Internet of things'." Those web-connected devices making up the Internet of Things will provide great convenience as well as a treasure trove of data waiting to be intercepted or data-mined.

  We know that smart meters can be real-time surveillance spies. At the last Chaos Communication Congress in Germany, researchers presented "Smart Hacking For Privacy" and demonstrated that detailed smart meter data can show what TV shows you watch, scan for copyright-protected DVD movies you watch, and other privacy intrusive details. Yet it took an amateur hacker only two days to hack a home smart meter and fake the readings -- which could result in a utility bill showing absolutely no power consumption at all.

  IEEE Spectrum previously explained, "It all sounds less paranoid when you consider that each appliance" has its "own energy fingerprint" that a smart meter can read. Who might want to read the smart meter data? Insurance companies to "determine health care premiums based on unusual behaviors that might indicate illness," or private investigators to "monitor specific events" or even criminals to learn high-priced appliances and the best times to steal them. Add to that mix the CIA, since household spy devices will "change our notions of secrecy," especially for anyone considered a "person of interest."

  Which Constitutionally protected rights would this infringe upon? According to the Supreme Court and the Fourth Amendment's protection, "In the home, our cases show, all details are intimate details, because the entire area is held safe from prying government eyes." The Fifth Amendment claims you do not have to incriminate yourself, don't have to witness against yourself, and you have the right to remain silent according to Miranda Rights. By moving to smart homes with smart appliances and the Internet of Things, which will connect every little device imaginable to the web, will that be considered the same thing as choosing to waive your rights?
