The principle of least privilege states that users and processes should be granted only the minimum permissions necessary to perform their specific role or function within an organization. This reduces the attack surface and limits the potential damage of a compromised account or process. References:

 When communicating via TLS, part of the handshake process involves presenting a certificate containing the server name, the name of the trusted CA that issued the certificate, and the public key of the server. The client can verify the validity of the certificate and use the public key to encrypt the data sent to the server. References := Cisco Cybersecurity Source Documents

Privileges required is a metric in the Common Vulnerability Scoring System (CVSS) that measures the level of access needed to launch a successful attack. The higher the privileges required, the lower the severity of the vulnerability. The privileges required metric has three possible values: none, low, and high. None means that the attacker does not need any privileges to exploit the vulnerability. Low means that the attacker needs privileges that provide basic user capabilities. High means that the attacker needs privileges that provide significant or administrative control over the target. References: Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) - Cisco, page 2-17; 200-201 CBROPS - Cisco, exam topic 1.3.c

The weaponization step in the Cyber Kill Chain model involves creating or repurposing malware based on the information gathered during reconnaissance to exploit vulnerabilities in the target’s system. This step culminates in the preparation of the malware to be delivered to the victim2.

 In Wireshark, to filter traffic for a specific LAN, the correct syntax uses ip.src== and ip.dst== to specify the source and destination IP addresses. The /16 denotes the subnet mask, indicating that we are interested in the entire 10.11.x.x range. This filter will show all traffic where both the source and destination IP addresses fall within the specified LAN, excluding any internet traffic. References: The information is based on the Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) course, which covers network intrusion analysis and the use of tools like Wireshark for traffic analysis1.

Role-Based Access Control (RBAC) is an approach to restricting system access to authorized users based on their roles within an organization. It depends on the job functions that individual users have as part of their responsibilities and is designed to reduce administrative work by assigning roles based on job competency, authority, and responsibility. References: Cisco Cybersecurity Operations Fundamentals, Module 1: Security Concepts, Lesson 1.2: Data Protection, Topic 1.2.2: Access Control Models

TOR is a network that enables anonymous communication over the internet by routing the traffic through a series of relays or nodes. TOR alters the data content during transit by encrypting it and the destination information over multiple layers, using a technique called onion routing. Each layer of encryption can only be decrypted by a specific relay in the network, which reveals the next destination. This way, no single relay knows the complete path or the content of the data, making it difficult to trace or monitor the communication. References := Cisco Cybersecurity Operations Fundamentals, Module 2: Security Monitoring, Lesson 2.1: The Network as a Sensor, Topic 2.1.3: Network Data Exfiltration Techniques

Application whitelisting/blacklisting is a technology used to control which applications are allowed to execute on a company’s corporate PCs. Whitelisting allows only approved applications to run, while blacklisting prevents specific applications from running. This approach is effective for managing application usage across an enterprise.
