What is Security Zones:
Security zones refer to network security architecture that divides a network into different security segments or zones, based on the security requirements of the resources and the level of trust placed on the devices within those zones.Security zones refer to network security architecture that divides a network into different security segments or zones, based on the security requirements of the resources and the level of trust placed on the devices within those zones.
Types of Security Zone:
1- Inside Zone
2 - Outside Zone
3 - DMZ
Inside Zone: This is the most trusted zone within a network where the internal users, servers, and resources are located. The inside zone is protected by firewalls and other security measures that ensure only authorized users have access to it.
Outside Zone: This is the least trusted zone and refers to the untrusted network outside the organization, such as the Internet. The outside zone is considered a high-risk area, as it is accessible by hackers and other malicious actors who can launch attacks against the network.
DMZ: The DMZ is a buffer zone that sits between the inside zone and the outside zone. It is designed to provide an additional layer of security and separate the publicly accessible services from the internal network. The DMZ typically hosts servers that provide services such as email, web applications, and FTP. These servers are accessible from both the inside and outside zones, but the DMZ acts as a barrier that limits the impact of an attack on the internal network.
By implementing these security zones, organizations can enforce access controls and reduce the risk of unauthorized access to critical resources. The use of firewalls, intrusion detection systems (IDS), and other security measures can further enhance the security posture of the network.
