In this modern day and age, wireless networks are everywhere. It is not a far stretch to say that it is downright crucial due to its ability to keep people connected and updated everywhere from universities and workplaces down to our personal homes. Though the benefits of wireless networks are undeniable, it also brings a new host of security concerns due to the amount of sensitive data being transmitted through these networks. A simple attack such as packet sniffing is enough to “sniff” out just enough data to cripple even giant corporate bodies if left unchecked. The aim of this research paper is to dissect and discuss the security and privacy issues of wireless networks that surround us. An interesting finding would be that wireless networks are heavily susceptible to both malicious attacks such as denial of service attacks and passive attacks like eavesdropping. It was also noted that information is more easily obtainable through wireless networks as compared to wired networks due to the ability to gleam information from long distances without having to be physically present on site. A literature review and a survey were conducted to learn about the opinions of casual users of wireless networks. The information gathered suggests that while there are many who care about privacy, they still lack the necessary knowledge to protect said privacy. These users carelessly connect to public wireless networks wherever it is available without proper precaution and care. Appropriate relevant solutions are presented based on literature study to overcome insecure wireless network usage practices in order to avoid active and passive attacks.
