CCZT Exam Dumps - Certificate of Competence in Zero Trust (CCZT)

To detect and stop malicious access attempts in real-time within a Zero Trust Architecture, comprehensive audit logging and continuous monitoring are essential. These measures provide visibility into all access attempts and activities within the network, allowing for the early detection of suspicious behavior. By analyzing logs and monitoring network traffic, security teams can identify and respond to potential threats in real-time, preventing unauthorized access and minimizing the impact of any security incidents.

Data and asset classification should be based on the sensitivity of data, which is the degree to which the data requires protection from unauthorized access, modification, or disclosure. Data sensitivity is determined by the potential impact of data loss, theft, or corruption on the organization, its customers, and its partners. Data sensitivity can also be influenced by legal, regulatory, and contractual obligations.

Data and asset classification is a prerequisite action to understand the organization’s protect surface clearly because it helps to identify the most critical and sensitive data and assets that need to be protected by Zero Trust principles. Data and asset classification also helps to define the appropriate policies and controls for different levels of data and asset sensitivity.

During the monitoring and analytics phase of ZT transaction flows, organizations should collect statistics and profile the behavior of transactions to support a continuous assessment of all transactions. A continuous assessment of all transactions means that the organization constantly evaluates the security posture, performance, and compliance of each transaction, and detects and responds to any anomalies, deviations, or threats. A continuous assessment of all transactions helps to maintain a high level of protection and resilience in the ZTA, and enables the organization to adjust and improve the policies and controls accordingly.

Different SDP deployment models have different advantages and disadvantages depending on the organization’s use case, such as the type of resources to be protected, the location of the clients and servers, the network topology, the scalability, the performance, and the security requirements. Network architects should consider their use case before selecting an SDP model that best suits their needs and goals.

A critical product of the gap analysis process is the implementation’s requirements, which are the specifications and criteria that define the desired outcomes, capabilities, and functionalities of the ZTA. The implementation’s requirements are derived from the gap analysis, which identifies the current state, the target state, and the gaps between them. The implementation’s requirements help to guide the design, development, testing, and deployment of the ZTA, as well as the evaluation of its effectiveness and alignment with the business objectives and needs.

A key architectural consideration that needs to be taken into account while deploying SDP is how SDP deployment fits into existing network topologies and technologies. This is because SDP deployment may require changes or adaptations to the existing network infrastructure, such as routers, switches, firewalls, VPNs, etc. SDP deployment may also affect the network performance, availability, scalability, and resilience. Therefore, it is important to assess the impact and compatibility of SDP deployment with the existing network topologies and technologies, and to plan and design the SDP deployment accordingly.

According to NIST, the key mechanisms for defining, managing, and enforcing policies in a ZTA are the policy decision point (PDP), the policy enforcement point (PEP), and the policy information point (PIP). The PDP is the component that evaluates the policies and the contextual data collected from various sources and generates an access decision. The PEP is the component that enforces the access decision on the resource. The PIP is the component that provides the contextual data to the PDP, such as the user identity, the device posture, the network location, the resource attributes, and the environmental factors.
