3 Secure Networks

Network security is a critical aspect of your role. You must understand and implement security measures such as firewalls, anti-virus software, and intrusion prevention systems to protect against threats. Familiarize yourself with security protocols like Secure Sockets Layer (SSL) and Transport Layer Security (TLS) for encrypting data in transit. Regularly update these systems and conduct security audits to ensure the network is secure from internal and external threats. Remember, a secure network is a fundamental requirement in protecting an organization's data and resources.
