Data Breach Threat

Network Security

• A firewall's primary role is to prevent specific types of information from moving between different network levels.

Firewall Types

• Dynamic firewalls can react to emergent events and update or create rules dynamically.
• Stateful firewalls are not capable of dynamically updating or creating rules.
• Hybrid firewalls are not specifically defined for dynamic rule creation or update.
• Static firewalls cannot dynamically update or create rules.

Intrusion Detection Systems (IDS)

• The primary purpose of an IDS is to identify system intrusions and alert administrators.
• Signature recognition IDS detects intrusions by comparing incoming events with a database of known attack patterns.
• Protocol anomaly detection IDS, anomaly detection IDS, and host-based IDS are not specifically designed for signature recognition.

Denial of Service (DoS) Attacks

• The primary goal of a DoS attack is to make a network or service unavailable to users.
• DoS attacks do not primarily aim to intercept communications, steal sensitive information, or gain unauthorized access to a system.

Security Mechanisms

• Accountability ensures that all system actions can be attributed to an authenticated identity.
• Authentication, authorization, and identification are not directly related to attributing system actions to an identity.

Firewall Functionality

• Packet-filtering firewalls examine the header information of data packets to determine whether to deny or allow them.
• MAC layer firewalls, application layer firewalls, and hybrid firewalls do not operate based on packet header information.

Network Traffic Management

• In a switched Ethernet environment, a switch handles network traffic by storing MAC addresses of all machines in a CAM table.
• Switches do not handle network traffic by ignoring packets, flooding packets, or broadcasting packets.

Insider Threats and Attacks

• Insider threats involve attackers leveraging human errors and system misconfigurations to breach security.
• Phishing, data breach, and ransomware are not directly related to insider threats.

Network Interface Card (NIC) Operation

• In a shared Ethernet environment, a NIC operates in promiscuous mode to capture all network traffic.
• Broadcasting mode, passive mode, and multicast mode are not related to capturing all network traffic.

Data Breach and Security Threats

• A data breach involves the release of sensitive or confidential data to an untrusted environment.
• Malware, phishing, and cyberextortion are not directly related to data breaches.

Security Event Management

• Security information and event management (SIEM) software is capable of importing security event information from various network traffic-related sources and correlating events among them.
• Intrusion detection systems, protocol analyzers, and packet sniffers are not designed for event correlation from multiple sources.

Identification in Access Control

• The purpose of identification in access control is to prove the user's identity.
• Assigning access levels, recording system actions, and verifying system use are not directly related to identification in access control.
