NTFS stands for New Technology File System, which is a proprietary file system developed by Microsoft4. NTFS is the default file system for the Windows NT family of operating systems, which includes Windows 10, Windows Server 2019, and other versions5. NTFS provides features such as security, encryption, compression, journaling, and large volume support45. NTFS is not the native file system for other operating systems, such as macOS, Linux, or Android, although some of them can read or write to NTFS volumes with third-party drivers or tools

The SSID (Service Set Identifier) is the name of a wireless network that is broadcasted by the router or the Wi-Fi base station. The SSID helps nearby devices to identify and connect to the available networks. However, broadcasting the SSID also exposes the network to potential connection attempts from unauthorized or malicious users. Therefore, disabling the SSID can mitigate connection attempts by making the network invisible or hidden to the devices that are not already connected to it. To connect to a hidden network, the user would need to know the exact SSID and enter it manually.

The other options are not related to mitigating connection attempts to the corporate Wi-Fi. DHCP (Dynamic Host Configuration Protocol) is a protocol that assigns IP addresses to the devices on a network. Firewall is a software or hardware device that filters the incoming and outgoing network traffic based on predefined rules. SSD (Solid State Drive) is a type of storage device that uses flash memory to store data. Disabling any of these options would not prevent connection attempts to the Wi-Fi network, and may cause other problems or issues for the network functionality and performance.

The customer’s web browser is likely infected by a browser hijacker, which is a type of malware that changes the browser’s settings and redirects the user to malicious websites. A browser hijacker can also steal the user’s personal data, display unwanted ads, and install more malware on the device. To remove a browser hijacker, the user should first uninstall the browser from the Control Panel, then scan the device with an antivirus or anti-malware program, and finally install a trusted browser from a legitimate source. Deleting the browser cookies and history, resetting the browser settings, or changing the browser default search engine may not be enough to get rid of the browser hijacker, as it may have embedded itself into the system or other browser components. 

A content filter is a device or software that blocks or allows access to web pages based on predefined criteria, such as keywords, categories, or ratings. A content filter can also create a log of the blocked or allowed web requests, which can help the management team monitor and audit the web usage of their employees. A content filter is different from the other options because:

A screened subnet is a network segment that is protected by two firewalls, one facing the internet and one facing the internal network. A screened subnet can isolate servers or hosts that need to be accessed from both sides, such as a web server or a bastion host. A screened subnet does not filter web content based on predefined criteria, but rather on network addresses, ports, and protocols.

Port forwarding is a technique that allows a router to forward packets from one port to another port, usually on a different device. Port forwarding can enable remote access to services or applications that are hosted on a private network, such as a web server or a game server. Port forwarding does not filter web content based on predefined criteria, but rather on destination ports and addresses.

An access control list (ACL) is a set of rules that defines which packets are allowed or denied on a network device, such as a router or a firewall. An ACL can filter packets based on source and destination addresses, ports, protocols, and other criteria. An ACL can also create a log of the matched or unmatched packets, which can help the management team troubleshoot and secure their network. An ACL does not filter web content based on predefined criteria, but rather on packet headers and fields.
