 Adaptive Zero Trust Data Protection Overview:

Netskope's Adaptive Zero Trust Data Protection ensures that data is protected based on continuous risk assessments and adaptive policies that respond to changing contexts and threats.

 Contextual Risk Awareness:

This capability involves understanding the context around data access and usage to assess risk dynamically.

Netskope leverages various signals such as user behavior, device security posture, location, and other factors to gauge risk levels.

By continuously evaluating these factors, Netskope can enforce appropriate security measures in real-time.

 Continuous Adaptive Policies:

Policies in the Netskope platform adapt continuously based on the assessed risk and changing contexts.

These policies are not static; they evolve based on ongoing risk assessments and threat intelligence.

Adaptive policies ensure that security measures are always aligned with the current threat landscape and organizational requirements.

To monitor IPsec tunnels to a Netskope data plane, it is essential to ensure the stability and responsiveness of the tunnels. The recommended steps involve enabling monitoring mechanisms that detect and respond to tunnel failures. Here’s a detailed explanation of the two recommended steps:

Enable IKE Dead Peer Detection (DPD) for each tunnel:

Explanation: IKE Dead Peer Detection (DPD) is a method used to detect if the peer (remote endpoint of the tunnel) is no longer available or reachable. By enabling DPD, the device can automatically detect and tear down the IPsec tunnel if the peer does not respond, allowing for quick re-establishment of the tunnel if needed.

Implementation: Configure DPD in the IPsec settings of the perimeter device. This ensures that if the Netskope data plane is unreachable, the tunnel is automatically terminated and re-negotiated.

Send ICMP requests to the Netskope location's Probe IP:

Explanation: Sending ICMP requests (ping) to the Netskope location's Probe IP helps in monitoring the availability and latency of the connection to the Netskope data plane. If the ICMP requests fail, it indicates a potential issue with the connectivity.

Implementation: Set up regular ICMP requests (ping) from the perimeter device to the Netskope Probe IPs. This allows for continuous monitoring of the tunnel’s health and immediate detection of connectivity issues.

Deploying a Netskope Virtual Appliance (NPA) can serve multiple purposes within an organization's security infrastructure. Two key uses are:

To use as a log parser to discover in-use cloud applications:

The Netskope Virtual Appliance can be deployed to parse logs from various sources, including firewalls, proxies, and other network devices. By analyzing these logs, the appliance can discover and identify cloud applications that are being used within the network. This provides visibility into shadow IT and helps in managing and securing cloud application usage.

To use as an endpoint for Netskope Private Access (NPA):

The virtual appliance can act as an endpoint for Netskope Private Access, enabling secure access to private applications hosted in data centers or public clouds. It facilitates the establishment of secure, direct connections between users and the applications they need to access, without exposing the applications to the public internet.
