TOPIC 3 : COUNTERMEASURE IN CYBERSECURITY, Level of IT infrastructure,…

- - - - i.Configuration Settings: Standardized settings for operating systems and applications.
      - ii.Patch Management: Regular updates and patches to fix vulnerabilities.
      - iii.Access Controls: Defined user roles and permissions to ensure only authorized access
- - - - Signal Encryption: Ensuring that wireless signals are encrypted to prevent unauthorized access.
      - Access Control: Using strong passwords and authentication methods to control who can access the network.
      - Signal Isolation: Limiting the range of wireless signals to prevent them from extending beyond the intended area
    - - Faraday Cages: Enclosures made of conductive materials that block electromagnetic fields, preventing electronic eavesdropping and interference2.
      - Physical Barriers: Using walls, barriers, and secure rooms to physically isolate sensitive equipment.
      - EMI Shielding: Using materials that block electromagnetic interference to protect sensitive electronic equipment.
    - - Fire Alarms and Detectors: Installing smoke detectors and fire alarms to provide early warning of a fire.
      - Automatic Fire Suppression Systems: Using systems like sprinklers, gas-based suppression (e.g., FM-200), or foam systems to automatically extinguish fires.
      - Regular Maintenance: Ensuring that all fire suppression equipment is regularly inspected and maintained to function correctly when needed.
- - - - Monitors and controls incoming and outgoing network traffic based on predetermined security rules
    - - (Virtual Private Network) Creates a secure, encrypted connection over a less secure network. Allows users to send and receive data as if their devices were connected to a private network.
    - - (Intrusion Detection System) Monitors network traffic for suspicious activity and potential threats. Can be configured to alert admins when unusual patterns are detected
    - - Decoy systems or networks designed to attract cyber attackers. It mimic real systems to lure attackers away from real targets. Can also gather information about their attacking methods
    - - (Demilitarized Zone) A physical or logical subnetwork that seperates an internal LAN from other unknown networks.
    - - Involves continuously observing a network for performance issues, failures and security threats.
- - - - It includes databases, data warehouses, and storage systems, as well as tools for data backup and recovery.
      - Data infrastructure focuses on storing, managing, and protecting information.
