If your business deals with sensitive information (e.g., credit card numbers, personal health information, or classified government data), you must be aware of the Security Technical Implementation Guide (STIG). STIGs are a set of security guidelines published by the Defense Information Systems Agency (DISA) and the US Department of Defense (DoD) agency. STIG is designed to help DoD organizations secure their information systems.

To help organizations ensure and enhance security in their systems and products, creating and using a STIG checklist is of great importance. It assesses security concerns and identifies potential vulnerabilities that malicious actors could exploit. This article will discuss what a STIG checklist is, its role in cybersecurity, and why it’s essential.

 

What is a STIG Checklist?

A STIG checklist is an organized and methodical tool used for verifying the security posture of various systems and software. It consists of detailed instructions that guide users through every step of the process, ensuring compliance with the stringent security standards set by DISA and the DoD.

The STIG checklist covers a wide array of elements, including hardware, software, and network protocols, and requires a thorough review of each to identify any potential vulnerabilities. These checklists are regularly updated to incorporate the latest security practices and to counter new threats, making them an essential resource for maintaining cybersecurity in a constantly evolving digital landscape.

 

Why is a STIG Checklist Important?

STIG checklists are crucial for maintaining cyber safety. These checklists enable the Defense Information Systems Agency (DISA) to standardize their efforts, safeguarding the US government and military systems against potential malicious attacks. Without STIGs and their accompanying checklists, achieving this level of standardization would be challenging, leaving these systems vulnerable.

DISA, a branch of DoD, is the originator of STIGs. These guidelines were set to safeguard military and civilian government systems from cyber threats and vulnerabilities. Today, there are more than a hundred STIGs in effect, with regular updates corresponding to product and service upgrades. By utilizing a comprehensive STIG checklist, government agencies and organizations adhere to DISA standards and mitigate the potential for cyberattacks.

While monitoring cybersecurity risks, government agencies also carry out comprehensive inspections to ensure overall security. They use these checklists to evaluate the vulnerability of their systems and identify and repair any weaknesses before they can be exploited. In certain instances, particularly when dealing with hardware, the general inspection is conducted in conjunction with the STIG inspection as they are considered part of routine maintenance.

STIG checklists are equally utilized in the private sector, mirroring their use and significance in the government. As cyber threats continue to evolve and pose increased risks, private IT products and services associated with the DoD must adhere to STIGs. By aligning with the government’s STIGs, the products and services can also be utilized by the public sector as necessary, ensuring their effectiveness across both domains.

Ensuring compliance with STIG not only determines the eligibility of private IT products and services for sale and operation in the US, but it also plays a crucial role in safeguarding the security of customers from both the public and private sectors. Non-compliance can have far-reaching consequences, impacting government operations and potentially exposing the country to cyberattacks. The technologies most vulnerable to these threats are those handling personal information (e.g., mobile numbers, emails, and locations).

 

What’s Included in a STIG Checklist?

A STIG checklist typically comprises several key components, each designed to ensure that every aspect of an IT product or service is evaluated for potential security vulnerabilities. The comprehensive nature of these checklists ensures that nothing is overlooked, offering the highest level of assurance in the security posture of these resources. Here, we’ll delve deeper into the integral components of a STIG checklist.

  • Name of Examined Product or Service: The specific IT product or service is being evaluated for potential security vulnerabilities. It could be a piece of hardware, a software application, or a network protocol.
  • Its Last Upgrade or Update (if applicable): The date of the product or service’s last upgrade or update is important as it could influence the security vulnerabilities present. Outdated versions of software, for instance, may be more susceptible to certain types of attacks.
  • List of Important Aspects that Affect Cybersecurity: This involves an extensive list of the product or service’s features and functionalities that can impact its cybersecurity. It could be anything from a software’s data encryption techniques to a hardware’s susceptibility to physical tampering.
  • Actions to be Taken to Address These Risks: For each identified risk, the checklist includes specific actions that should be taken to mitigate that risk. This could include updating software, modifying hardware configurations, or implementing new security protocols.
  • Metric to Assess the Importance of Each Risk to Overall Safety: This is a rating or scoring system (e.g., low, medium, high severity; Category 1, 2, or 3) that’s used to determine the impact each identified risk could have on overall safety. It helps prioritize mitigation efforts based on the severity of each risk.

 

Categories of STIG

There are several categories of STIG that cater to different aspects of a system’s security. They provide specific guidelines and checklists for various areas of IT and cybersecurity. Here are some of the major categories:

  1. Application Security STIG: This category deals specifically with the security of software applications. It contains guidelines and checks for ensuring that your applications are free from vulnerabilities that malicious entities could exploit. This typically includes testing for weak points in the application’s code and ensuring that the application adheres to best practices for data access and storage.
  2. Network/Perimeter/Wireless STIG: This category focuses on the security of your network and wireless systems. It includes checks and guidelines to ensure your network is secure against external threats. This involves testing the integrity of your network’s perimeter (the boundary between your internal network and the outside world) and your wireless systems.
  3. Operating Systems STIG: This category of STIG pertains to the security of your operating systems. It includes checks for vulnerabilities in how your operating systems are set up, including how data is stored and accessed, the security of the user accounts on the system, and the system’s resistance to various attacks.
  4. Database STIG: This category focuses on the security of your databases. It includes guidelines and checks for ensuring that your databases are secure against attacks that could compromise data integrity or confidentiality.
