Debunking Some Common Myths

Let’s take a minute before we move on to debunk some common myths about cyber security.

How are these myths established?

There’s no one cause for these myths. 

They may have been formed because of a lack of information, an assumption, knowledge of a specific case that was then generalized, or some other source. 

As with any myth, they are passed from one individual to another, usually because they seem legitimate enough to be true.

Why is it important to know the truth?

While believing these myths may not present a direct threat, they may cause you to be more lax about your security habits. 

If you are not diligent about protecting yourself, you may be more likely to become a victim of an attack.

So let’s go over some common myths and what the truth is behind them:

Myth #1: Anti-virus software and firewalls are 100% effective.


Truth: Anti-virus software and firewalls are important elements to protecting your information. 

 

However, neither of these elements are guaranteed to protect you from an attack. 

Combining these technologies with good security habits is the best way to reduce your risk.

We’ll cover both of these in more depth in Understanding Anti-Virus Software and Understanding Firewalls later on in the course.

Myth #2: Once software is installed on your computer, you do not have to worry about it anymore.


Truth: Vendors may release updated versions of software to address problems or fix vulnerabilities. 

We’ll cover this process in Understanding Patches later on.

 You should install the updates as soon as possible. 

Some software even offers the option to obtain updates automatically. 

Making sure that you have the latest virus definitions for your anti-virus software is especially important.

Myth #3: There is nothing important on your machine, so you do not need to protect it.


Truth: Your opinion about what is important may differ from an attacker's opinion. 

If you have personal or financial data on your computer, attackers may be able to collect it and use it for their own financial gain. 

Even if you do not store that kind of information on your computer, an attacker who can gain control of your computer may be able to use it in attacks against other people. 

You’ll learn more about these kinds of attacks in our “Understanding Denial-of-Service Attacks” module and our “Understanding Hidden Threats: Rootkits and Botnets” modules later on in the course .

 

Myth #4: Attackers only target people with money.


Truth: Anyone can become a victim of identity theft. 

Attackers look for the biggest reward for the least amount of effort, so they typically target databases that store information about many people. 

If your information happens to be in the database, it could be collected and used for malicious purposes. 

It is important to pay attention to your credit information so that you can minimize any potential damage. 

You’ll learn more about this in our “Preventing and Responding to Identity Theft” module later on in the course.

Myth #5: When computers slow down, it means that they are old and should be replaced.


Truth: It is possible that running newer or larger software programs on an older computer could lead to slow performance…

 but you may just need to replace or upgrade a particular component  like the memory, operating system, CD or DVD drive, etc.. 

Another possibility is that there are other processes or programs running in the background. 

If your computer has suddenly become slower, it may be compromised by malware or spyware, or you may be experiencing a denial-of-service attack. 

You’ll learn more about this in our Recognizing and Avoiding Spyware module and our Understanding Denial-of-Service Attacks module.

I’ll see you in the next video.
