Network Hardening Techniques (N10-009)
Welcome to the Network Hardening Techniques Practice Lab. In this module, you will be provided with the instructions and devices needed to develop your hands-on skills.
Network hardening implements security measures to protect a network from unauthorized access, attacks, and data breaches. Techniques include disabling unused ports on network devices such as switches, routers, and firewalls to reduce the attack surface, configuring Access Control Lists (ACLs), as well as changing default passwords to help prevent unauthorized access and lower the risk of credential-based attacks.
