Attack Prevention: Preventing Cyber Attacks
Technology is everywhere, which is evident in the everyday products that we as a society use
such as computers, cell phones, global positioning devices, and the Internet. As technology
expands and grows, so does the reliance and dependence on these types of products. But reliance
and dependence are not the only things that technology brings. Cyber attacks are a gradually
increasing occurrence that is derived from technology; however, stopping these types of attacks
before they occur is usually more difficult than can be expected, but is overall not impossible.
The trick to averting such an attack lies in the programs and applications that one uses for
defense that recognizes, detects and notifies the user that an attack is imminent. This can be
something as simple as a malware and/or virus program to something more complex such as a
firewall. The purpose of this paper is to discuss what constitutes a cyber attack, examine the
steps involved in a cyber attack, and determine how to prevent them, which was discussed in the
article by Tony M. Damico entitled Cyber Attack Prevention for the Home User: How to Prevent
a Cyber Attack (2009) and other sources.
Cyber Attack: What It Is
A cyber attack, also known as Cyber Warfare, is “an attempt to undermine or compromise the
function of a computer-based system, or an attempt to track the online movements of individuals
without their permission” (WiseGeek, 2011). To put it in simpler terms, a cyber attack is the
targeting of something electronic to make them malfunction so that some type of reward can be
collected. As mentioned in the first definition, cyber attacks fall into two basic categories: those
acts that are intended to collect information and those that are intended to do harm. Cyber attacks
that are specifically carried out for the sole purpose of information gathering range from tracking
the movements that a user makes to copying important documents contained upon a hard drive,
