Ensuring network security involves implementing various measures, including: Firewalls: Install firewalls to monitor and control incoming and outgoing network traffic, preventing unauthorized access. Encryption: Use encryption protocols to secure data transmissions and protect sensitive information. Access control: Implement strong authentication mechanisms, such as passwords or multi-factor authentication, to restrict unauthorized access to the network. Regular updates and patches: Keep network devices and software up to date with the latest security patches and firmware updates. Intrusion Detection and Prevention Systems (IDPS): Deploy IDPS tools to detect and prevent network intrusions and suspicious activities. Employee awareness and training: Educate employees about best practices for network security, such as avoiding phishing scams and using secure passwords.
