Introduction

The use of social media sites has far outpaced the ability of IT professionals to keep them secure.As you might suspect, the largest and most popular sites are primary targets. To understand the depth of the problem, we will need to discuss the difference between privacy and security.

End users have much control of their privacy by regulating what they post, but very limited control of their security, which should be the responsibility of the social networking site.

To illustrate these concepts, we will look at different type of vulnerabilities and the challenges of protecting social media sites. We will briefly discuss some of the popular attack scenarios. Finally, we will examine the protection mechanisms an end user could apply to enhance his or her well-being.

Introduction

End users have much control of their privacy by regulating what they post, but very limited control of their security, which should be the responsibility of the social networking site.

The difference between privacy and security in social media sites

Protecting your privacy involves restricting your personal, sensitive, and confidential information from others. Of course, there may be various levels of privacy, as we saw in Facebook in unit 1.

For example, you may be willing to share that you got a new dog named Sparky with your close friends/family, but not with all other Facebook users, because a hacker might be able to apply social engineering and try to use “sparky” as part of a hacking dictionary search to break one of your passwords, as described in unit 3.

In terms of ensuring privacy, you as an end user have a lot of control. You can limit, for example, what you post on sites such as Facebook and who you are willing to share it with. So it is important that you devise your own policy to help you control what you post. This policy will vary depending on what type of social network you are using.

Characteristics of secure passwords

Strength based on length and character set size

One of the first considerations when devising a password is to consider the length. Generally, themore characters in the password and the larger the character set, the longer it will take to defeat.

To put this into perspective, let’s look at three of the passwords mentioned earlier and see how difficult they might be to break using a brute-force approach.

The brute-force method tries in sequence every combination of appropriate letters and/or numbers. Let’s start with the password 2345.

The brute force attack method will start with 0000 (assuming the hacker knows the password is limited to four digits and no other characters) and increment by 1 until it reaches the actual value of 2345.

Therefore, the maximum number of tries that it will take would depend on the number of different characters used (0-9)—in this case, 10. That value is then raised to the length of the password: in this case, four characters.

So the probability of guessing the password in one try would be 1 chance in 10 to the 4th power, or 1 in 10,000.

In theory the password could be anything, and if the person chose 1234, then the probability is the same for guessing that password as any other four-character password.

However, hackers
