The Difference in NTFS Permissions vs Windows Sharing

-

 


 

NTFS permissions and Windows share permissions are two distinct sets of access controls used in the Windows operating system to regulate access to files and folders on a network. While they serve a similar purpose, there are some key differences between the two:

Scope:

NTFS Permissions: These permissions apply to the local file system of a Windows computer. They are effective when accessing files and folders directly on the computer's hard drive.

Windows Share Permissions: These permissions are specific to shared folders and network resources. They determine the access rights for users accessing files and folders over the network.

Application:

NTFS Permissions: They are utilized when accessing files and folders locally, whether through the physical computer or a network connection.

Windows Share Permissions: These permissions come into play when accessing files and folders over the network, specifically when using shared folders.

Level of Control:

NTFS Permissions: They offer more granular control over individual files and folders on a local computer. You can assign permissions to specific users or groups and define different levels of access, such as read, write, modify, or full control.

Windows Share Permissions: These permissions provide a broader level of control for shared resources. They can only be set at the shared folder level and apply to all files and folders within that share. The available permission levels are read, change (read and write), or full control.

Interaction:

NTFS Permissions: They are independent of Windows share permissions. When accessing files locally, NTFS permissions take precedence and control access to the files regardless of the share permissions.

Windows Share Permissions: They work in conjunction with NTFS permissions when accessing files over the network. Both sets of permissions are evaluated, and the most restrictive permission level is applied.

In summary, NTFS permissions govern local file system access, while Windows share permissions control access to shared folders over the network. NTFS permissions provide finer control at the file and folder level, while share permissions offer broader control at the shared folder level.

  Oracle has disclosed a critical vulnerability (CVE-2025-61882) affecting E-Business Suite versions 12.2.3 through 12.2.14. This pre-authentication remote code execution (RCE) flaw enables unauthenticated attackers to exploit multiple chained weaknesses — including SSRF, CRLF injection, authentication bypass, and unsafe XSLT processing — to gain full control of affected systems. Risk Assessment: Severity: Critical (CVSS 9.8) Exposure: Internet-facing Oracle EBS instances are at immediate risk Threat Activity: Active exploitation confirmed by threat intelligence sources, including Cl0p ransomware group Business Impact: Potential compromise of financial systems, data exfiltration, and operational disruption Recommended Actions: Immediate Patch Deployment: Apply Oracle’s July 2025 Critical Patch Update to all affected EBS environments. Network Segmentation: Restrict public access to Oracle EBS systems. Ensure they are isolated from internet-facing zones. Threat Monito...

Microsoft Defender for Endpoint (DFE) and Mitigation for It

-
Image
  The recent vulnerability affecting Microsoft Defender for Endpoint (DFE) involves critical flaws in how the agent communicates with its cloud backend, potentially allowing attackers to bypass authentication and manipulate incident response processes. Key Vulnerabilities in Defender for Endpoint (DFE) Authentication Bypass : Attackers can impersonate the Defender agent using only the machine ID and tenant ID, which are accessible to low-privileged users via registry reads. This allows them to spoof commands and responses. Command Interception : By querying endpoints like /edr/commands/cnc , attackers can intercept or fake responses (e.g., falsely reporting a device as isolated), undermining actual security status. Certificate Pinning Circumvention : Researchers bypassed HTTPS protections by patching memory functions (e.g., CRYPT32!CertVerifyCertificateChainPolicy ) to inspect traffic in plaintext using tools like Burp Suite and WinDbg. Azure Blob Upload Exploits : Attackers c...

Active Directory Synchronization Bug – September 2025 Affected Systems : Windows Server 2025 machines with KB5065426 or later updates installed. Issue : Applications using the DirSync control (e.g., Microsoft Entra Connect Sync ) fail to fully synchronize large AD security groups (groups with over 10,000 members). Impact : Incomplete synchronization of large groups Disruption in identity and access management Potential issues in hybrid cloud environments relying on accurate group membership Mitigation : Microsoft has released a temporary registry workaround A permanent fix is expected in a future Windows update Here is the PowerShell script that: Checks if KB5065426 or later is installed Applies the registry workaround to mitigate the DirSync bug affecting large AD security groups What the Script Does: Searches for installed hotfixes matching KB5065xxx . If found, it sets the registry key: HKLM\SYSTEM\CurrentControlSet\Services\NTDS\Parameters\UseLegacyGroupE...
