What is the Purpose and Function of Homeland Security?
Re: https://www.masterofhomelandsecurity...-security.html

Homeland security is a relatively new field and many students don’t even realize that this is an educational option. However, it is a growing field, and with workers in high demand across the country, it is a great option for people interested in policy, law, finance, politics, and other related fields.

General Role of Homeland Security

In general, homeland security is all about keeping the United States a safe place. This involves passing laws and writing new policy, fighting crime, and preventing terrorism, among other things. Homeland security is about protecting the freedoms we’re afforded in the United States, while also ensuring citizens are safe.

Specialized Homeland Security Functions

To get into the nitty-gritty details, let’s take a look at some of the specializations in homeland security. Workers in this area deal with the following areas:

Immigration and Border Security

Cybersecurity

Counterterrorism

Disaster Response and Recovery

Within each of these area, there are even more specialized areas within homeland security. For example, under counterterrorism, you’ll find people dealing with nuclear site security, fraud and counterfeit, aviation security, chemical security, information sharing, law enforcement, and more.

Where is Homeland Security in Place?

Homeland security is an enormous enterprise that encompasses other important government programs such as the National Terrorism Advisory System and TSA that strive to keep our country save. However, homeland security is also a state responsibility. For example, the Department of Homeland Security has great information about what they call Hometown Security, which includes what individuals can do to keep their neighborhood safe.

Why is Homeland Security Necessary?

In order to keep Americans safe, policies and systems have to be in place to stop attacks and prevent our resources from being overwhelmed. In addition, homeland security keeps the United States prepared for natural disasters. Homeland security is often about learning from mistakes. Today’s policies and systems are set in place to avoid events like 9/11 and to better prepare for natural disasters like Katrina to save lives and avoid damage. The role of homeland security is constantly evolving to keep up with the needs of the country.
