Abstract

The goal of this project is to explain and describe how importance of cyber security in today's society and going over some of the different types of security. Furthermore, I will also be focusing on exploring one of the many features of cyber security. Encryption what is it and why does it matter.

Introduction

Cyber security is defined as a process of protecting various devices (servers, computers, phones, etc.), electronic systems, different networks, and data on those networks from any form of malicious attacks. However, while cyber security is used to group together there are many different types of cyber security. Some of the different tools used to protect your data include. VPN – Or virtual private network, is used to encrypted the connection going from the Internet coming from a device to a network. This encrypted connection is used to helps ensure that sensitive data is safely and securely transmitted and is not intercepted. It also helps to prevent unauthorized people from eavesdropping on other people’s data while allowing the user to conduct work remotely. DHCP – Or Dynamic Host Configuration Protocol (DHCP) is a protocol that is used for assigning dynamic IP addresses to devices on a network. With dynamic addressing, a device can have a different IP address every time it connects to the network. In some systems, the device's IP address can even change while it is still connected. DHCP also supports a mix of static and dynamic IP addresses. NAT - Stands for "Network Address Translation." NAT translates the IP addresses of computers in a local network to a single IP address. This address is often used by the router that connects the computers to the Internet.

Methodology

Depending on what your doing depends on which measure you should use an example if you are torrenting or even if you want to watch a movie from a different region on Netflix and/or Hulu you should use a VPN as I will make your network think you are somewhere else. DHCP is used to give device or devices their own unique code or IP address that changes. If you are in an office and you can use a NAT which will give the same IP address to all the computers in that network used most often to across networks remotely.

Results

While they all fall under the category of cyber security, they each have their own purpose. VPN’s to protect and redirect locational data, DHCP used to assigning dynamic IP addresses to devices on a network, and NAT across networks remotely.

Conclusion

Whether you use VPN, DHCP, or NAT they are all used to protect you data.

Future Work

In the future, I will be sure to remember these options when worried about cyber security.
