How to be safe on the internet. Make the web better!

  1. 1. Make the web better How to be safe on the internet by vectorialpx.net
  2. 2. First rule of security: trust nobody And some other simple rules:
  3. 3. 1. Do not give your passwords to friends and don't type passwords in public places. If you really need to, look both ways and make sure no one can see your hands. This is not a joke! Lots of accounts got "hacked" this way.
  4. 4. 2. Do not use your password (login) in unknown networks, like public wiFi networks (hotels, McDonalds or others) There may be some dude (proxy)between you and the internet that can record any action (request) between you and any server (website). Even your passwords. What can you do? When you are at home, check "Keep me logged in" on the website so when you get into public places you will not need to enter your password.
  5. 5. 3. Never click on unknown links. Before you click a link make sure you check the address from the address bar. I hate short links!!! (even fb.me or t.co ... all of them)
  6. 6. NOTE1:When you check the address bar make sure it is a perfect match. As example: if it's a mail from PayPal and the link is something like http://client12.paypl.com you should not click it. The domain must be PayPal.com and not paypl.com. Do not assume that an email from paypal.com is safe. The sender can easy be changed. Note2: Never complete a login forms unless you checked the address-bar twice. You may get into pages that look like the Yahoo! (just an example) interface BUT there is another address, another website. It is a copy of the interface to just make you enter (give) your password.
  7. 7. 4. Do not give passwords to any support desk, bank agent or other person that will tell you that "it's safe!" to do it. Any support desks or administrator must have access to your account (of any type) without your password.
  8. 8. Never store passwords in plain text (on paper, in your browser, in your phone, in your computer)
  9. 9. Do not have stupid passwords Make sure that your passwords contains at least one special character and at least one digit and it's over 8 characters. If you have any password that doesn't meet this, go and change it right now.
  10. 10. Why is this important? Well, read this if you like technical stuff: the simplest method of getting passwords is a savage one, named brute-force. This method consists into entering all combinations of letters and even digits until a valid password is found. If you add a special character and a digit into your password and you make it long enough (over 8 chars) you will add billions of brute-force combinations. Most of the big websites logins are protected against bruteforce (it's nothing sure) but a simple security breach could lead to database records or files that store passwords. If you have a strong password, it will be impossible to "unhash" it. A hash is a computed value of a string with a one-way algorithm. So, once a password is hashed it cannot be unhashed BUT you can make brute-force over it and trying lots of combinations you can find the valid hash. A programmer needs just few lines of code to create a brute-force. And, of course, a lot of time.
  11. 11. Ok, how can I have a strong password? As example: my name is Octavian and my password can be "0C5@vi1N" and it's easy for me to remember. We have: 0 (zero) is like "O" + big "C" + 5 is over "T", @ looks like "A", we also have "vi" as simple string, 1 is over "A" and, in the end a big "N". So, it's my name in a new way. If you need, you can use something like http://password.phpadminpanel.com or even a password manager
  12. 12. Another important thing about passwords: make sure you have a different password for every important service that you have - Email, Facebook, forums, games, FTP accounts (if you are a developer) and other accounts. Why should I do that? Sometimes, in my past, I got a website to maintain. I was surprised to see that all passwords recorded until that time are in plain text. You could just see passwords (even now, I cannot understand how a programmer can be that stupid). So I took some random password and the email of the account and just tried into the Yahoo! login form (it was a Yahoo! email). It was amazing to find out that 3 of 5 users had the same passwords for their emails. Of course, next thing, I hashed all passwords. So, never have the same password for two services because you cannot know who will bump into your clear password. At least you will lose one account, not your entire internet life.
  13. 13. Have alternate ways for your password recovery. As example, have an alternate email to recover your password. Both Yahoo! and Google will allow a second email address that can reset your password. Also, if you can, add your phone number for trusted websites so this will also be a new method to recover your password. If you don't have an alternate email, add it now!
  14. 14. Make sure you have a good updated antivirus and you make a scan once a month A good antivirus will also have a firewall. In case it does not, make sure your OS (ie: Windows) firewall is ON. Also, update your system at least once a month because there are security updates that you may need.
