What Is a Security Clearance and Why You Need One

Protecting sensitive and classified information from unauthorized access is of utmost importance to both governments and organizations, primarily because the same information can be a weapon. It is impossible to trust all individuals with sensitive or confidential information, which is why security clearance exists. Security clearances are mandated when you work for the government, contract with federal contractors, or work in the information security or cybersecurity fields. Educating yourself about the concept of security clearance, it will allow you to better prepare yourself for employment opportunities that require a great deal of trust, responsibility, and integrity.

What is Security Clearance

A security clearance is an official authorization that allows an individual to access classified information or areas. This is issued after an in-depth investigation of the individual being granted clearance. This investigation is intended to determine whether or not the person will pose a threat to national security, the security of the organisation and/or the sensitive operations of that organization. The fact that someone has been given security clearance indicates that there has been a comprehensive investigation and an assurance that the person being granted clearance will be responsible in regard to his or her handling of classified materials.

Most government employees, especially those in defence, intelligence agencies, or private contractors that support the government, require security clearance, but even in the private sector, several Cyber Security and Technology roles require some form of security clearance because of the sensitive nature of the data being stored, processed or transmitted. Therefore, a security clearance is proof that a person can be relied on to be responsible with the handling of classified information and can be trusted with the protection of sensitive materials.

Different Types of Security Clearances Explained

In general, security clearances come in a variety of types. Most people think of security clearance as a single type; however, this is not correct. Security clearance has many levels and types based on the amount of risk associated with the information contained within each level/type of clearance.

For example, Security Clearance (Confidential) provides access to information that could cause harm or danger if that information were obtained or released inappropriately. Security Clearance (Secret) provides access to information that could seriously harm the United States if released. Therefore, Security Clearance (Secret) provides (in addition to Confidential clearance) additional scrutiny of the applicant’s financial history and character. Top Secret security clearance is the most comprehensive security clearance and the least available security clearance because it provides access to information of extraordinary risk to the United States’ national security if released. It is a very comprehensive process whereby applicants are often interviewed by multiple persons based on the social, personal, occupational, and other aspects of their background and character.

Additionally, higher levels of security clearance exist to limit access to sensitive information by only those people who need access to it, based on the sensitive nature of the information and the security risk associated with it.

How the Security Clearance Process Works

The Security Clearance Process is a comprehensive and systematic way to help reduce risk by following a prescribed set of steps. The Security Clearance Process starts with a detailed Application. You will be asked to provide a significant amount of information on your background, including your personal history, previous employment, financial records, travel history, and references (personal and professional) to email or mail in after completing your application. Ensure that you provide accurate information for the entire Application; even minor errors can delay or prevent you from obtaining your Clearance.

Once your Application is submitted, your background will go through an investigation phase. During this phase, the investigator will verify the information provided in your Application and review your Criminal History Record, your Credit History, and any Previous Employment. The investigator may also contact individuals who have known you personally and/or professionally to evaluate your Character and Behavior.

After the completion of an investigation, it is then necessary for the investigator to carefully analyze the investigation’s findings against the eligibility criteria for obtaining a Security Clearance. In obtaining approval for Security Clearance, an individual may gain access to Sensitive Information. The Security Clearance will not have an indefinite duration; thus, it must periodically undergo re-evaluation and/or renewal in order to verify continued compliance with the requisite Security Clearance standards.

Due to the extent of the time involved in processing and completing the necessary documentation, utilizing the services of a qualified, experienced professional may make a major difference when attempting to avoid errors and expedite the application process.

Why Security Clearance Is Important for Your Career

A security clearance exposes opportunities for professionals to further advance. Professionals who possess and maintain an active security clearance, especially in fields such as Cyber, Defense and Government Contracting, provide employers with the ability to reduce the time and costs associated with hiring and onboarding. Individuals with an already established security clearance will have a strong competitive advantage against their peers during the interview process.

Security clearance goes beyond job placement or employment opportunities; it also provides higher compensation levels for many professionals, greater job stability and the ability to work on projects that directly benefit an organization and/or the nation’s safety. Security clearances signify that the holder has completed extensive due diligence and vetted through established standards that confirm the individual can be trusted with sensitive information and will fulfill their obligations successfully. Security clearances are not only a requirement for a professional to work in a particular field, but also serve as valuable assets.

Conclusion

A security clearance is much more than an administrative requirement; it’s a testament to your safe-trusting capability, responsible stewardship of sensitive materials, and professional credibility. The type of clearance you have will greatly influence your ability to be successful in your career, whether you’re looking for a new position or continuing to develop in your current role.
