Terms you need to know 3-leg perimeter A type of DMZ where a firewall has three legs that connect to the LAN, the Internet, and the DMZ. 10 tape rotation A backup rotation scheme in which ten backup tapes are used over the course of two weeks. 802.1X An authentication technology used to connect devices to a LAN or WLAN. It is an example of port‐based network access control (NAC). Acceptable use Often defined as a policy, acceptable use defines the rulesthat restrict how a computer, network, or other system may be used. Access control list (ACL) A list of permissions attached to an object. ACLsspecify whatlevel of access a  user, users, or groups have to an object. When dealing with firewalls, an ACL is a set of rules that applies  to a list of network names, IP addresses, and port numbers. Access control model Specifies methodologies by which admission to physical areas and,more importantly, computer systems, is managed and organized. Access control mechanism  Securi...

 Analyze and differentiate between the various types of security controls. • Categories of Security Controls: - Technical: These are controls implemented through technology. They include hardware, software, or firmware components built into information systems. Examples include firewalls, antivirus software, and encryption. Technical controls are automated and rely on technology to enforce security measures. - Managerial: These controls focus on overall risk management and the administration of cybersecurity systems. They involve policies, procedures, and practices that guide the organization's security posture. Examples include risk assessments, security planning, and resource allocation for security initiatives. - Operational: These are controls implemented and executed primarily by people rather than systems. They involve day-to-day security practices and procedures carried out by staff. Examples include security awareness training, physical patrols, and manual log reviews. - Ph...

  In the ever-evolving landscape of data protection, implementing a secure and reliable backup storage technology is crucial for maintaining data integrity. This document outlines the most advanced and secure backup storage technologies available as of 2024, focusing on data integrity and security. 1. Zero-Knowledge Encryption Overview Zero-knowledge encryption ensures that only the data owner can access and read the stored information. The service provider has no knowledge of the encrypted data or the encryption keys. Implementation Use client-side encryption before data transmission Employ strong encryption algorithms (e.g., AES-256) Ensure encryption keys are managed solely by the client 2. Multi-Factor Authentication (MFA) Overview MFA adds an extra layer of security by requiring two or more verification factors to access the backup system. Implementation Implement a combination of: Something you know (password) Something you have (security token) Something you are (biometric v...
