A low-interaction honeypot, like Kojoney, is designed to emulate specific network vulnerabilities and gather information about attackers without providing a full-fledged operating environment. These honeypots are typically easier to deploy and maintain compared to high-interaction honeypots. They simulate certain services and responses to attract attackers, allowing the network security team to gather data on attack patterns, tools, and methodologies used by the attackers. This information is crucial for understanding the attack and improving defenses.

• High-interaction honeypots: Provide a complete environment that can fully engage with attackers, offering more detailed insights but also posing higher risks.
• Pure honeypots: Essentially full-scale, unmodified systems that an attacker interacts with.
• Research honeypots: Used primarily for gathering information for research purposes, often involving high-interaction setups.

To effectively correlate incidents across various security controls like firewalls and IDS systems, it is essential to ensure that the timestamps of logs and events are synchronized. This is where Network Time Protocol (NTP) comes into play. NTP ensures that all devices on the network are on the same time setting, which is crucial for event correlation. Without synchronized time settings, it would be challenging to establish a timeline of events and understand the sequence in which they occurred, making incident response and forensic analysis more difficult.

References: The importance of using NTP for incident correlation is well-documented in network security best practices and is also highlighted in the EC-Council’s Certified Network Defender (CND) course materials. The CND course emphasizes the role of NTP in maintaining accurate time stamps across network devices for effective security incident management and analysis.

 The Encrypting File System (EFS) is a feature of the NTFS file system that provides encryption at the file system level. It is designed to work specifically with NTFS and does not support the FAT file system. When files encrypted with EFS are copied or backed up to a volume that uses the FAT file system, the encryption is lost because FAT does not support EFS encryption. This is why David found that the backup files were not encrypted after transferring them to a system that supports the FAT file system.

References: The explanation is based on the operational characteristics of EFS and its compatibility with different file systems as described in the Certified Network Defender (CND) course materials and further supported by information from reliable sources on EFS and file system encryption1234.

The strategy described is known as a “default deny” firewall policy. This approach means that the firewall is configured to deny all traffic by default, except for the network services that are explicitly allowed. It is a restrictive security stance where only specified services are permitted, and everything else is blocked. This is considered a best practice in firewall configuration because it minimizes the attack surface by ensuring that only necessary services are accessible, thereby reducing the potential vectors for attack.

References: The concept of a default deny policy is a fundamental principle in network security and is advocated by various cybersecurity authorities, including the EC-Council’s Certified Network Defender (CND) program. It is also detailed in cybersecurity literature and aligns with best practices from organizations such as the National Institute of Standards and Technology (NIST)123.
