Advanced Network Security

Advanced network security encompasses a range of sophisticated techniques designed to secure modern enterprise networks, focusing on layered defenses, real-time monitoring, network segmentation, and the establishment of encrypted channels. Technologies such as IDS/IPS systems are crucial for identifying and mitigating threats, while firewalls and VPNs safeguard data during transmission. Implementing a Zero Trust model fosters a more secure environment by ensuring that trust is not assumed for any user or device within the network.
