Information Security

Client-side state management should not be used for sensitive information (tampering risk) or critical applications (unreliable). It's more appropriate for controlled environments like intranets where security is less of a concern. Public-facing applications with sensitive data need server-side state management.

Cisco IOS supports comprehensive security: 'service password-encryption' encrypts all passwords in the config, 'enable secret' secures privileged mode, 'password' can be set on VTY/Console lines, and AAA (TACACS+/RADIUS) provides external authentication. Thus, all are true.

The 'netsh' command can be used to manage IPSec policies. Configuring the policy as dynamic ensures that the settings are applied and updated correctly across the domain environment. Static policies are usually manually assigned and less flexible for domain-wide enforcement.

User-level security provides the most granular control by authenticating individual users rather than groups or shares. Each user has unique credentials and permissions that are independently managed, making it more secure than share-level or resource-level models.

Encryption and decryption are primarily presentation layer (Layer 6) functions in the OSI model. The presentation layer handles data translation, encryption, and compression. While encryption can also occur at the application layer, the OSI model specifically assigns it to the presentation layer.

Intrusion Detection Systems (IDS) require system resources (CPU, memory, and I/O) to monitor traffic or log files. This overhead often results in host performance degradation, which is a common security tradeoff for increased visibility.

To answer this question, the user needs to understand the purpose of the security log in Windows 2000 server.

The security log in Windows 2000 server is primarily used for auditing purposes. It records events related to security and authentication, such as successful or failed logon attempts, changes to user accounts and permissions, and other security-related events.

Therefore, the correct option is:

The Answer is: C. auditing.

A written security policy establishes the foundation by defining what needs protection, acceptable use, incident response procedures, and compliance requirements. Technical controls and user training must flow from this documented plan to be effective.

Error Proofing (Poka-Yoke) mechanisms prevent errors by designing processes that make mistakes impossible or immediately detectable. Using employee ID validation against a database is a classic example - it creates a foolproof check that prevents unauthorized logins. This differs from simple inspection, which catches defects after they occur, rather than preventing them.

Abstraction involves showing only essential features and hiding implementation details from the user. It focuses on what an object does rather than how it does it. Encapsulation bundles data and methods together. Information hiding is a related principle but more restrictive. Polymorphism allows objects of different types to be treated uniformly.

IP spoofing involves hackers forging their IP address to appear as a trusted machine on the network, allowing them to gain unauthorized access. Phishing tricks users into revealing credentials, forging is a general term (not specific to IP addresses), ID theft involves stealing personal identity information.

Smart Cards in Windows 2000 use the Extensible Authentication Protocol (EAP) as the RAS authentication protocol. EAP provides a framework that supports multiple authentication methods, including smart card-based authentication via certificate-based credentials. PAP is plain-text (insecure), CHAP and MS-CHAP are challenge-response protocols for passwords, while EAP is specifically designed to accommodate smart cards and other advanced authentication methods.

Application security is indeed a critical business need in today's digital landscape. Data breaches can result in massive financial losses, reputational damage, and legal consequences. Protecting applications is essential for safeguarding customer data and maintaining business continuity.

Application security protects organizations from data breaches, financial losses, and reputational damage. Cyberattacks can cost millions and destroy customer trust. Security is now a core business requirement, not just IT concern, with legal and regulatory implications (GDPR, data protection laws).
