When securing a company’s network, implementing multiple layers of controls is key. Administrative controls include security policies, employee training, and access management procedures. These define how users and systems should behave to protect company data. Technical controls involve firewall, intrusion detection systems, antivirus software and encryption, which safeguard digital assets from unauthorized access and cyber threats. Physical controls such as locked server rooms, surveillance cameras, and restricted access protect hardware and infrastructure. Companies can also use network segmentation to isolate sensitive data reducing exposure if breach occurs. Regular audits, vulnerability assessments, and timely updates further strengthen security. Altogether, combining administrative, technical and physical controls creates a strong defense system, to ensure the company’s network remains secure and resilient against both internal and external threats.
