Short Answer 
National security involves defending a nation’s sovereignty through the executive branch, primarily the president. Key steps to enhance it include identifying vulnerabilities, strengthening infrastructure, and excluding potential threats through background checks and monitoring.
Step 1: Understanding National Security
National security is defined as the defense and protection of a nation’s sovereignty, encompassing its people, economy, and institutions. This responsibility primarily falls under the executive branch of government, specifically the president, who plays a crucial role in safeguarding these interests. The main objective is to ensure that the country’s vital needs are preserved against various threats.
Step 2: Identifying Vulnerabilities
To enhance national security, it is essential to identify areas that are particularly vulnerable to attacks. This involves assessing potential risks and taking steps to fortify these weak spots. Effective measures may include:
- Conducting threat assessments.
- Strengthening infrastructure and public safety.
- Implementing surveillance and monitoring systems.
Step 3: Excluding Potential Threats
Another critical aspect of national security is excluding individuals who may pose a threat. This involves screening processes and monitoring activities that ensure potentially dangerous individuals cannot compromise security. Key actions include:
- Conducting background checks.
- Utilizing intelligence reports.
- Implementing access controls to sensitive locations.
