The Encrypted File System (EFS) is a feature of the NTFS file system available in Windows that provides filesystem-level encryption. It allows for the transparent encryption of files, protecting confidential data from attackers who might gain physical access to the computers. EFS uses a combination of symmetric key encryption and public key technology to protect files. The symmetric key, known as the File Encryption Key (FEK), is used to encrypt the file data, and then the FEK itself is encrypted with a public key associated with the user’s identity and stored with the file. This ensures that only authorized users can decrypt the encrypted files. EFS is particularly suitable for protecting sensitive data on laptops that might be lost or stolen, as it ensures that the data remains inaccessible without the appropriate encryption key.

References: The information about EFS is consistent with the features and capabilities as described in the Windows documentation and resources on filesystem-level encryption123.

Having a web server within the internal network can pose a threat to network security because it increases the attack surface that an adversary can exploit. If not properly secured, internal web servers can be vulnerable to various attacks, such as SQL injection, cross-site scripting, and others. These vulnerabilities can lead to unauthorized access, data breaches, and other security incidents. Therefore, it is crucial to ensure that web servers are securely configured and isolated from the internal network to minimize the risk.

References: The EC-Council’s Certified Network Defender (CND) program discusses the importance of understanding the attack surface and the potential threats associated with having critical services like web servers within the internal network. The program emphasizes the need for strategic placement of network resources and the implementation of robust security measures to protect against internal and external threats1

 In Transport mode encryption of an IPsec server, only the payload of the data packet is encrypted. This mode is designed to encrypt the message within an IP packet, while the header remains unencrypted. Transport mode is used for end-to-end communication between a client and a server, where the server can interpret the headers to route the packet to the correct application or process.

References: The information is consistent with the IPsec standards and documentation, which specify that in Transport mode, the data within the original IP packet is protected, but not the IP header123. This ensures that the packet retains its original IP header, allowing it to be routed properly through the network.
