Study Notes
Passive Attacks
- The goal of a passive attack is to intercept and monitor network traffic without altering it.
- Passive attacks are typically detected through the use of intrusion detection systems (IDS) and traffic analysis.
- To prevent the success of passive attacks, encryption and secure communication protocols should be used.
Active Attacks
- An impersonation attack, where one entity pretends to be another, is a type of active attack.
- Active attacks like Masquerade are difficult to prevent because they often involve complex authentication and access control mechanisms.
- The main goal of a replay attack is to intercept and retransmit sensitive information, such as login credentials.
Denial of Service (DoS) Attacks
- A denial of service attack is characterized by an attempt to make a computer or network resource unavailable by overwhelming it with traffic.
Key Differences between Passive and Active Attacks
- A passive attack differs from an active attack in that it involves intercepting and monitoring network traffic without altering it, whereas an active attack involves altering or modifying the data.
Authentication in Network Security
- The primary focus of authentication in network security is to verify the identity of users, devices, or systems.
Data Modification Attacks
- A data modification attack differs from a replay attack in that it involves altering or modifying the data in transit, whereas a replay attack involves retransmitting intercepted data.
Common Forms of Active Attacks
- A common form of an active attack is a masquerade attack, where an attacker impersonates a legitimate user or device.
Active Attack Goals
- The main goal of an active attack is to disrupt, deny, degrade, or destroy information system resources.
Encryption in Network Security
- The purpose of encryption in network security is to protect data in transit from interception and unauthorized access.
Disruptive Attacks
- A denial of service attack aims to disrupt, deny, degrade, or destroy information system resources.
