    Zero Trust Architecture

    • Zero Trust security demands verification for every device, user, and transaction within a network, regardless of its origin.
    • To create a Zero Trust architecture, two planes are used: Control Plane and Data Plane.
    • The Control Plane defines, manages, and enforces access policies within an organization.
    • The Data Plane ensures that these policies are executed properly.

    Control Plane Components

    • Adaptive Identity: Utilizes context-based authentication, considering factors like user location, device type, security, and configuration requirements.
    • Threat Scope Reduction: Limits the blast radius of potential security breaches by using least privilege and identity-based network segmentation.
    • Policy-Driven Access Control: Policies are enforced through Policy Engines and Policy Administrators.
      • Policy Engines use rules and external systems (like threat intelligence, identity management, and SIEM) to make access decisions.
      • Policy Administrators execute decisions made by the Policy Engine.

    Data Plane Components

    • Implicit Trust Zones: Allow access and movement once a subject is authenticated by a Zero Trust Policy Engine.
    • Subjects and Systems: These are the devices and users seeking access.
    • Policy Enforcement Points: Enforce access policies as defined by the Control Plane.

    Zero Trust Access Control: Policy-Driven Approach

    • Zero Trust security relies on policy-driven access control.
    • Policy Engines use predefined policies to make access decisions.
    • Policy decisions are enforced by the Policy Administrator and Policy Enforcement Points.
    • The NIST model outlines the role of the Policy Administrator in executing decisions made by the Policy Engine.
    • Implicit trust zones exist within the Data Plane, granting access and movement after successful authentication by a Zero Trust Policy Engine.
    • Subjects and systems (subject/system) represent devices and users seeking access.
    • Policy Enforcement Points align with the NIST description, enforcing access decisions based on policies.

    Technical Controls

    • Technical controls are security measures implemented through technology to help protect systems and data.
    • Examples of technical controls: firewalls, intrusion detection systems (IDS), antivirus software, encryption.

    • Operational controls are security measures focusing on procedures, policies, and practices to ensure the effectiveness of security measures.

    Physical Controls

    • Physical controls are security measures that physically protect assets and resources.
    • Examples of physical controls: locks, security guards, fences, surveillance systems.

    Types of Security Controls

    • Preventive controls aim to stop security incidents from occurring.
    • Detective controls focus on identifying and reporting security incidents after they happen.
    • Corrective controls aim to restore systems to their normal state after security incidents.
    • Deterrent controls aim to discourage attackers.
    • Compensating controls are alternative security measures used to replace or enhance existing controls.
    • Directive controls outline the rules and regulations for security practices.

    Gap Analysis

    • Gap analysis identifies the differences between the desired security posture and the current state of security controls.

    • Plan of Action and Milestones (POA&M) outlines the steps to address identified security gaps.
    • Technical gap analysis focuses on IT infrastructure and systems.
    • Purpose of gap analysis:
      • Identify areas for improvement
      • Determine the resources needed for remediation
      • Ensure compliance with regulations

    Zero Trust

    • Zero Trust security model assumes no trust in users, systems, or devices, even on internal networks.

    Components of Zero Trust

    • Control Plane:
      • Enforces security policies and access decisions
      • Adaptive identity: adapts access based on user context and behavior.
    • Policy Engine:
      • Determines access permissions based on security policies
      • Threat scope reduction: reduces the attack surface by limiting access.
    • Data Plane:
      • Carries out actions determined by the Policy Engine

    Zero Trust Terminology

    • Least privilege: Users and systems have access only to the resources they require.
    • Trust Algorithm: evaluates the risk of each request based on user, device, and context.
    • Policy Administrator: manages and updates security policies.

    Policy-Driven Access Control

    • Policy-driven access control relies on predefined security policies to grant or restrict access.
    • Enforcement: The process of applying access rules based on the policy.

    Preventive Control Goals

    • One of the main goals of preventive controls in security is to mitigate risks before they can impact an organization.

    Preventive vs Detective Controls

    • Preventive controls are designed to stop incidents before they happen, while detective controls are used to identify and respond to incidents that have already occurred.

    Gap Analysis

    • The initial step in conducting a gap analysis is to define the desired security posture.
    • This involves identifying security goals and objectives.

    Business Gap Analysis

    • In a business gap analysis, the current security practices versus the desired security posture are evaluated.
    • This helps in identifying any gaps between the two and devising strategies to close those gaps.

    Plan of Action and Milestones

    • A POA&M typically outlines the actions and timelines required to address security vulnerabilities and improve the overall security posture of an organization.

    Purpose of Gap Analysis

    • The primary purpose of conducting a gap analysis is to identify discrepancies between the current security state and the desired security state within an organization.

    Technical Infrastructure Gap Analysis

    • A technical infrastructure gap analysis focuses on the security of an organization's technology-based infrastructure.
    • It assesses the effectiveness of security controls and identifies potential vulnerabilities within the infrastructure.

    Control Plane

    • Within a Zero Trust architecture, the Control Plane determines who or what is authorized to access data or resources.
    • It uses policies and rules to govern access decisions.

    Adaptive Identity

    • The concept of adaptive identity within the Control Plane refers to dynamically adjusting access permissions based on context and user behavior.
    • It considers factors such as location, device, and user activity to grant or deny access.

    Threat Scope Reduction

    • In the Zero Trust framework, the main purpose of threat scope reduction is to minimize the impact of a security breach by limiting the reach of a compromised system.
    • This involves restricting connections and access rights to only essential resources.

    Data Plane

    • The Data Plane carries out the actions based on the decisions made by the Policy Engine.
    • It enforces the access control policies established by the Policy Engine.

    Policy Engine

    • The Policy Engine in a Zero Trust model determines whether a user or device should be granted access to a resource based on pre-defined policies.
    • It also applies various security controls such as multi-factor authentication and encryption.

    Least Privilege

    • 'Least privilege' in Zero Trust means granting only the minimum necessary permissions to users and systems to perform their required tasks.
    • This principle minimizes the potential harm that can be caused by a security breach.

    Data Plane Characteristics

    • The Data Plane in Zero Trust architecture is NOT characterized by policy enforcement.
    • The Policy Engine is responsible for policy enforcement, while the Data Plane handles the execution of access decisions made by the Policy Engine.

    Trust Algorithm

    • The 'trust algorithm' used by Policy Engines evaluates the risk associated with a particular user or device attempting to access a resource.
    • The algorithm assesses various factors such as user identity, location, device status, and network connectivity.

    Policy Administrator

    • The Policy Administrator in a Zero Trust architecture is responsible for creating and managing the access policies and controls within the Control Plane.
    • They ensure that policies are aligned with the organization's security goals and make adjustments as needed.

    Policy Enforcement

    • The component primarily responsible for matching and enforcing security policies in a Zero Trust environment is the Policy Engine.
    • It assesses the compliance of users and devices with defined policies, and applies appropriate controls to enforce access decisions.

    Implicit Trust Zones

    • Implicit trust zones in the Data Plane allow movement of certain user traffic to specific resources once the user is authenticated.
    • This is a specific implementation detail within the Data Plane and is not necessarily a core concept of the Zero Trust principle.

    Subjects & Systems

    • In the Zero Trust model, subjects refer to users and systems, while systems refer to resources like apps, servers, and databases.

    Policy Engine in Access Control

    • A primary function of a Policy Engine in Zero Trust access control is to enforce access policies and determine which users or systems should be granted access to specific resources based on predefined rules.
    • The Policy Engine plays a key role in securing resources in a Zero Trust environment.

    Policy-Driven Access Control

    • The primary focus of policy-driven access control is to ensure that users and systems have only the necessary access to resources based on predefined policies and roles.
    • It promotes the principle of least privilege and strengthens security posture.

    Access Management

    • Policy-driven access control primarily addresses the aspect of authorization, which is the process of determining whether a user or system has permission to access a specific resource.
    • It's a fundamental component of robust access management practices.

    Honeypot Primary Function

    • The primary function of a honeypot in cybersecurity is to entice and trap malicious actors, allowing security professionals to study their activities and techniques and develop better defenses.

    Honeynets vs. Honeypots

    • Honeynets differentiate from honeypots by being a collection of multiple interconnected honeypots that mimic a production environment.
    • This broader infrastructure allows for more comprehensive monitoring of attacker behaviors and potential attacks.

    Honeyfiles

    • Honeyfiles primarily assist in cybersecurity efforts by acting as decoys or bait within a system.
    • They lure attackers into accessing or interacting with them, revealing their intentions and providing valuable intelligence for security analysis.

    Honeytokens

    • Honeytokens within an organization's security framework act as hidden and uniquely identifiable data elements.
    • They are designed to trigger alerts or track malicious activity when accessed or manipulated.

    Honeypot Usage

    • Honeypots are used to lure attackers into a controlled environment, allowing security professionals to monitor their activities and gather intelligence about their tactics.
    • This information helps in developing countermeasures and improving an organization's overall security posture.

    Honeytokens vs. Traditional Data

    • Honeytokens function as a unique and identifiable form of data, often disguised as regular data, which is not valuable on its own.
    • They are designed to be attractive to attackers while triggering alerts when accessed.

    Honeynet Purpose

    • A honeynet's primary purpose is to create a simulated environment that mimics a real production network, allowing attackers to target it and be analyzed without affecting legitimate systems.
    • This provides a safe space to observe attacker behaviors and understand their tactics.

    Honeyfile Data

    • Honeyfiles usually contain artificial or decoy data.
    • They are designed to seem appealing and provide valuable information about any attacker who attempts to access or interact with them.

    Change Advisory Board (CAB)

    • The Change Advisory Board (CAB) plays a crucial role in the overall change management process by providing review and approval for proposed changes.
    • They assess the potential impact of changes on the organization, ensuring that risks are adequately addressed before implementation.

    Impact Analysis Factor

    • A successful impact analysis in change management depends on a thorough understanding of the potential impact of proposed changes on different aspects of the organization, such as business operations, systems, and user experience.

    Change Owner Responsibility

    • The change owner in the change management process is primarily responsible for managing the entire lifecycle of a change.
    • This includes planning, implementation, monitoring, and communication throughout the change process.

    Change Implementation Disruption Minimization

    • Testing is critical for minimizing disruption during change implementation.
    • Thorough testing helps identify and address any potential issues before the change is put into production.

    Stakeholder Involvement

    • Stakeholder involvement is crucial in the change management process because it ensures the needs and concerns of all involved parties are considered.
    • This leads to a more successful change process that meets the requirements of the business.

    Testing Results

    • Testing results after a change is implemented is to ensure that the change has been implemented correctly and does not have unforeseen negative effects on the system or business.

    Backout Plan

    • A backout plan is designed to revert the system to its previous state if the implemented change causes problems or unexpected disruptions.
    • It allows for rapid recovery in case of unforeseen issues.

    Standard Operating Procedures (SOPs)

    • Having Standard Operating Procedures (SOPs) in the change management process provides consistency and structure to the change process, ensuring that all changes are implemented in a standardized way.
    • This reduces the risk of errors and promotes a more efficient change process.

    Proposed Change Evaluation Key Factor

    • A thorough impact analysis ensures all proposed changes undergo a thorough evaluation before implementation.
    • This helps in identifying the potential impact of changes on the organization and making informed decisions about their implementation.

    Proposed Change Evaluation Element

    • Risk assessment is critical in the evaluation process of proposed changes to assess their impact on the organization.
    • This helps in identifying potential risks associated with the change and developing mitigation strategies before implementation.

    Insights & Oversight

    • Change Advisory Board (CAB) members play a significant role in providing insights and oversight for changes within an organization.
    • They bring together diverse perspectives and expertise to evaluate and approve proposed changes, ensuring that they align with the overall business goals and security posture.

    Stakeholder Involvement Effectiveness

    • Clear communication and active participation from all stakeholders enhance the effectiveness of the change management process.
    • This ensures that everyone is informed and involved in the change, fostering a sense of ownership and commitment.

    Overlooked Aspect in Poor Change Management

    • A lack of proper documentation is most likely to be overlooked in a poor change management process, leading to failures or disruptions.
    • Comprehensive documentation of changes, including their rationale, implementation steps, and testing results, is crucial for effective change management and troubleshooting.

    Allow Lists and Deny Lists

    • An Allow List specifies entities permitted to access a resource.
    • A Deny List specifies entities that are prevented from accessing a resource.
    • Both lists should be reviewed when proposing changes to ensure unintended access restrictions or grants are not implemented.

    Restricted Activities

    • Certain tasks are labeled as 'restricted' due to their impact on system health or security.
    • Proposed changes should be verified for any restricted activities to prevent data breaches and operational disruptions.

    Downtime

    • Any change has the potential to cause downtime.
    • The potential downtime should be estimated and its negative effects assessed against the benefits of the change.
    • Changes should be scheduled during maintenance windows to minimize impacts on end users.

    Service and Application Restarts

    • Some changes require service or application restarts, like installing security patches.
    • Restarting critical services can be disruptive, potentially causing data loss or backlog.
    • The implications of restarts, especially for key servers, need to be considered.

    Legacy Applications

    • Legacy applications are older software or systems still in use due to functionality and user needs.
    • They are less flexible and more sensitive to changes.
    • Minor updates can lead to malfunctions or crashes, so assessing their compatibility is crucial.

    Dependencies

    • Interconnected systems create dependencies, where changes in one area affect others.
    • Mapping dependencies is crucial before implementing changes to prevent cascading effects, outages, or disruptions in various parts of the network.

    Documenting Changes

    • Documenting changes provides a clear history of the what, when, and why for accountability and future reference.

    Version Control

    • Tracks and manages changes in documents, software, and other files.
    • Allows multiple users to collaborate and revert to previous versions when needed.
    • Ensures changes do not create chaos and helps track project evolution.
    • Preserves past iterations and ensures continuity and stability.

    Proper Documentation

    • All accompanying documentation should be updated when implementing a change.
    • Updates should reflect the implementation of the change, from minor configurations to major network overhauls.
    • Key elements of proper documentation include updating diagrams, revising policies and procedures, and updating change requests and trouble tickets.

    Continuous Improvement

    • After implementing a change, the process and its success should be evaluated.
    • Issues should be identified and policies and procedures revised to prevent recurrence.
    • This emphasizes iterative process improvement to ensure smoother future changes.
    • Learning from past mistakes improves change management practices.

    Importance of Records

    • Change requests and trouble tickets create a clear timeline of change actions.
    • This informs stakeholders and provides a record of change history for future reference.
    • Records are essential for communication and accountability in change management.

    Technical Implications of Changes

    • Restricted Activities: Certain tasks are labeled 'restricted' due to their potential impact on system health or security. Verifying proposed changes for any restricted activities is crucial.
    • Data Breaches and Operational Disruptions: Understanding restrictions helps prevent data breaches and operational disruptions.
    • Dependencies: Changes in one system can affect others due to interconnected systems.
    • Mapping Dependencies: Mapping dependencies is critical before implementing changes to prevent cascading effects, outages, or disruptions in various parts of your network.

    Key Elements of Proper Documentation

    • Updated Diagrams: Updating diagrams provides a visual representation of the system architecture.
    • Revised Policies and Procedures: Revising policies and procedures addresses identified issues or improvements.
