Network defense refers to the strategies and technologies used to protect computer networks from unauthorized access, attacks, and damage. This involves implementing firewalls, intrusion detection systems, and encryption to safeguard sensitive data. By monitoring network traffic and identifying potential threats, organizations can prevent cyberattacks and ensure the integrity of their information. Effective network defense also includes educating employees about cybersecurity best practices. Training staff to recognize phishing attempts and suspicious activities can significantly reduce the risk of breaches. Overall, a strong network defense combines technology and human awareness to create a secure digital environment for businesses and individuals alike.
