How Defense Contractors Use Cybersecurity

Defense contractors hold an important role in providing solutions for government entities. With access to sensitive information, they are often targeted by cyber attackers. Defense contractors must prioritize cybersecurity and perform regular self-audits to prevent breaches and protect vital information. Mnemonics adheres strictly to robust cybersecurity practices and compliance standards. We implement a multi-layered security architecture to thwart cyber threats and protect sensitive data. Mnemonics leverages cutting-edge technology and cybersecurity tools to monitor network activity, detect anomalies, and respond promptly to potential threats. 


Defense contractors handle sensitive information regarding national security, technological innovations, weapons systems, and military tactics that can be easily stolen by cybercriminals if left unsecured. 

Defense contractors employ a multipronged approach to cybersecurity, ensuring the protection of sensitive data at every level of operation. The strategy begins with computer asset hardening, where all devices on their networks are configured with the highest security settings to minimize vulnerability. This includes deactivating unnecessary applications and services, implementing secure configurations, and ensuring regular updates of all software components.

Moreover, encryption plays a crucial role in defense contractors’ cybersecurity strategies. They employ advanced encryption algorithms to protect data in transit and at rest, rendering it unreadable and useless to unauthorized entities. The industry is also exploring emerging encryption techniques, such as quantum-resistant algorithms and homomorphic encryption, to stay ahead of potential threats.

In the era of cloud computing, defense contractors prioritize cloud security. They use strategies like data encryption, in-transit and at-rest security, and multi-layered access controls to protect their cloud infrastructure. The ‘Zero Trust’ model has gained popularity, operating under the premise that every interaction, regardless of origin, must be authenticated and authorized. Additionally, regular security audits are conducted to identify vulnerabilities and assess the effectiveness of current security tactics.

Finally, the safeguarding of sensitive information is paramount. Defense contractors implement strict access controls, secure storage, and data handling protocols to prevent unauthorized access. This comprehensive approach to cybersecurity helps defense contractors protect vital national security information from cyber threats.


Self-auditing helps defense contractors to identify vulnerabilities in their systems and infrastructure. It is an essential process that provides an unbiased and thorough evaluation of their cybersecurity posture. Self-auditing can be done manually or by using automated tools. It helps defense contractors assess compliance with regulations, policies, and standards. A self-audit can also identify human errors, weaknesses, and areas for improvement.

Defense contractors audit themselves for cybersecurity compliance through a multifaceted process. Initially, they establish a benchmark according to regulatory requirements, industry standards, and best practices. Standards presented by organizations such as the Defense Federal Acquisition Regulation Supplement (DFARS) and the National Institute of Standards and Technology (NIST) must be followed.

The self-audit begins with an inventory check of all digital assets, system configurations, and application settings. Automated auditing tools are often employed to perform this comprehensive analysis, providing detailed reports on system vulnerabilities and potential risks. Subsequently, manual checks validate the findings of the automated systems with a thorough review of system access logs, network activity, and data handling practices. In addition, employees’ adherence to cybersecurity policies is assessed via simulated cyberattack scenarios. Lastly, the audit results are meticulously compiled, analyzed, and compared with the cybersecurity benchmark. Areas for improvement are then addressed through remediation strategies, such as security patches, software updates, and cybersecurity training programs.


Compliance with various regulations and standards is critical to defense contractors’ cybersecurity approach. One of the key standards is the NIST cybersecurity framework, which provides guidelines on managing cybersecurity risks. Defense contractors must align their cybersecurity strategies with NIST’s five core functions: identify, protect, detect, respond, and recover. In doing so, they ensure that they’re prepared for potential cyber threats and equipped to handle and recover from cyber incidents effectively.

The Defense Federal Acquisition Regulation Supplement (DFARS) is another important regulation that defense contractors must comply with. It requires contractors to provide adequate security to protect defense information on their networks and report cyber incidents to the Department of Defense. DFARS compliance validation is often part of the self-auditing process, ensuring the protection of Controlled Unclassified Information.
