    Study Notes

    Smart Card Authentication

    • Smart Card Authentication uses a card with a built-in microchip and memory to securely store personal data
    • Smart Cards are used for authentication to access various systems and applications
    • This method is more secure than traditional password-based authentication

    Single Sign-on (SSO)

    • SSO is a feature where users only need to log in once to access multiple applications with a single set of credentials
    • This reduces the need for multiple passwords and the risk of poor password practices
    • It also simplifies the user experience and reduces the load on the network by minimizing repetitive authentication requests

    Disabling a User Account in Ubuntu

    • The usermod command is used to manage user accounts in Ubuntu
    • The usermod -L alice command locks the user's password, effectively disabling the account and preventing login

    Internet Access Policies

    • A Prudent policy balances security and usability by allowing safe and necessary services while blocking potentially harmful activities
    • It also includes measures to hold employees accountable for their online activity

    Distributed Denial of Service (DDoS) Attacks

    • A DDoS attack uses multiple compromised devices to overwhelm a target system with traffic
    • This prevents legitimate users from accessing the system and effectively takes it offline
    • IoT (Internet of Things) devices can be vulnerable to DDoS attacks

    Network Services Specific Security Policy

    • This policy focuses on managing and securing services provided over the network
    • It ensures effective use of network resources, like bandwidth, in alignment with organizational goals

    TACACS+ Authentication Protocol

    • This protocol encrypts the entire authentication process, including credentials and subsequent communication
    • It provides a higher level of security than RADIUS, which only encrypts the password

    Initial Assessment in Incident Response

    • The first responder to a suspected security incident should immediately conduct an initial assessment
    • This involves evaluating the situation to understand the scope and impact of the incident
    • Initial assessment helps determine the next steps in incident response, such as escalation, resource allocation, and communication

    Maximum Time for Data Loss (RTO)

    • RTO (Recovery Time Objective) defines the maximum time an organization can tolerate data loss during an outage
    • This value is a crucial element of business continuity and disaster recovery planning

    Parabolic Grid Antenna

    • This antenna type is designed to focus radio waves in a specific direction
    • It can pick up Wi-Fi signals from long distances and is ideal for point-to-point communication in long-range Wi-Fi networks

    Blue Team in Information Security

    • The Blue Team is responsible for defending an organization's IT infrastructure
    • Their focus is on internal security measures, maintaining defensive protocols, and protecting systems and data from cyber threats
    • This team manages security controls, incident response, and the overall cybersecurity posture of the organization
