Cloud network defense refers to the protection of networks and network infrastructure within cloud environments, including virtual networks, subnets, and network resources such as load balancers, firewalls, and virtual private clouds (VPCs). The primary goal of cloud network security is to safeguard the confidentiality, integrity, and availability of data and resources transmitted over cloud networks, as well as to defend against various cyber threats and attacks.
Establishing isolated virtual networks within the cloud environment to logically separate resources and control network traffic flow, with considerations for IP addressing, subnets, routing.
Segmenting cloud networks into distinct security zones or tiers based on the sensitivity and trust level of the resources they contain, implementing access controls and traffic filtering to restrict communication between segments.
Configuring security groups and network ACLs to enforce network-level access controls and traffic filtering rules at the subnet and instance level, limiting exposure to potential threats and vulnerabilities.
Deploying and configuring cloud-native or third-party firewalls to filter incoming and outgoing network traffic, enforcing security policies, and blocking unauthorized access to network resources while allowing legitimate traffic to pass through.
Implementing IDS/IPS solutions to monitor network traffic for signs of malicious activity or policy violations, detecting and blocking suspicious or unauthorized behavior in real-time to prevent security inci.
