Common Network System Security Breaches

It seems like every time you turn around, a company has to deal with some kind of hacking issue. In fact, it is almost in epidemic proportions in some industries. More and more cyber criminals are attempting network system security breaches and getting away with it. To help you get a better understanding of what you are up against, let's look at some of the most common types of hacking occurring today.

Spear Phishing

Common phishing attempts are aimed at individuals and are usually sent with forged emails, appearing like financial institutions or other legitimate businesses. The goal is to get the recipient to think he or she is logging into a legitimate website and then "log in" information can be stolen and the thief can gain access to the account. The website may look real and appear to have a valid SSL certificate.

Spear phishing is a little different than standard phishing methods. This is an attempt to circumvent network system security by sending an email to someone within the company network. It can be as innocent looking as asking for specific information on products or services.

The email always contains an attachment or a link to click on which will take the recipient to a targeted website. Once the attachment is opened or link is clicked, a malware program will begin running and it will target an important program like Microsoft Excel or Word, or an email client like Outlook.

Sometimes hackers are just looking to infect one computer. They can then use the infected machine as a gateway to let others into the system. Sometimes network system security can be completely compromised this way. In addition to email attempts, spear phishing can also be accomplished through online chat or messaging programs.

Drive By Downloads

This maneuver gets its name from the drive by shootings which were common a few years ago. It's a simple yet effective tactic commonly used by criminals targeting large groups. They want to infect as many people associated with a website, organization or demographic region, as possible. Here is how it might work.

A hacker finds a vulnerability or "hole" in a website, where he or she can gain access. By getting into the website dashboard, a malicious code can be implanted and anyone simply visiting the website will be infected. This is why it is very important to never click on links in emails or any link you are not absolutely certain of. Although this is a hit and miss situation, it can be used to disrupt network system security a great deal.

Flash Drive Infections

Sometimes inexpensive flash drives may be given away as sales promotions and perhaps at your next conference. It's possible to place malicious programs on these drives and all you need to do is plug into your computer and it will load the program with an "autorun" feature.

Flash drive infections are also used by people to gain access to computer networks. It only takes a visitor a few seconds to stick one of these drives into a computer when no one is looking. This is why people must always be vigilant.


Many hackers and cyber criminals are scanners. In other words, they are constantly on the lookout for servers with hidden vulnerabilities. You can have exceptional network system security but when someone is scanning your system on a regular basis, they may uncover new vulnerability issues before you are aware of them. This is why it is important to have some kind of daily scanning service to counteract the "scanners" out in cyber space.

Once a scanner spots a vulnerability issue he can send a signal to the computer and exploit it.

WiFi Invaders

Some businesses and individuals make the mistake of not password protecting their WiFi networks, or else they make the passwords so simple they are easy to guess. For example, if a business called Brand X uses a password like xbrand, it will not be too hard for hackers to guess this password after a few tries.

Once someone gets into your network through WiFi they can wreak havoc because they are inside your system and have the equipment and knowledge to take advantage of you. They might steal customer information or steal sensitive information about patents, secret ingredients or processes.

The best way to avoid WiFi invaders is to use strong passwords. Make sure they contain letters, numbers and special characters.
