Study Notes

Security Measures

  • Train employees to avoid giving away passwords to prevent cheating by security personnel.

Email Phishing

  • Phishing occurs when a user receives an email that appears to be from a trusted source, such as a bank or employer.
  • The user is asked to click a link and log in to a fake website that mimics the genuine website.
  • The user's ID and password are then captured by the attacker.

Backups

  • A comprehensive backup plan is essential for the entire organization.
  • Data on corporate servers and individual computers should be backed up regularly.

Firewalls

  • Firewalls can exist as hardware or software (or both).
  • A hardware firewall is a device that filters packets based on a set of rules.
  • A software firewall runs on the operating system and intercepts packets as they arrive.
  • Firewalls protect all company servers and computers by stopping packets from outside the organization's network that do not meet a strict set of criteria.

Intrusion Detection Systems (IDS)

  • IDS is a device that can be placed on the network for security purposes.
  • IDS does not add any additional security, but instead, identifies if the network is being attacked.
  • IDS can be configured to watch for specific types of activities and alert security personnel if that activity occurs.

Virtual Private Network (VPN)

  • VPN allows users outside of a corporate network to access internal resources by taking a detour around the firewall.
  • VPN uses firewalls and other security technologies to make internal resources invisible to the outside world.

Physical Security

  • Physical security is the protection of the actual hardware and networking components that store and transmit information resources.
  • Measures include locked doors, physical intrusion detection (cameras), and environmental monitoring (temperature, humidity, and airflow).
  • Employee training is also essential for physical security.

Security Policies

  • A good information-security policy lays out guidelines for employee use of company resources and provides recourse in case of policy violations.
  • Policies must balance the need for security with users' need to access and use resources effectively.

Personal Information Security

  • Keep software up to date.
  • Install and update antivirus software regularly.
  • Be cautious when making connections.
  • Backup data regularly.
  • Use two-factor authentication to secure accounts.
  • Use long, strong, and unique passwords.
  • Be suspicious of strange links and attachments.

This quiz covers cybersecurity best practices, including training employees to keep passwords secure, recognizing email phishing scams, and creating comprehensive backup plans for organizations.
