Types of active attacks are Masquerade, session replay, denial of service, distributed denial of service. Types of passive attacks are the Release of a message, traffic analysis. It does not check for loopholes or vulnerabilities. It scans the ports and network in the search of loopholes and vulnerabilities.
What are active attacks?
An active attack is a network exploit in which a hacker attempts to make changes to data on the target or data en route to the target. There are several different types of active attacks. However, in all cases, the threat actor takes some sort of action on the data in the system or the devices the data resides on.
What is passive security mechanism?
A passive security system is one that is designed to discourage any threat to a particular good. In case such as attempt at tampering should occur, the system must make it difficult and delay it.

Which one is not encryption technique?
Solution(By Examveda Team)
FTP is not an encryption technique. The File Transfer Protocol is a standard network protocol used for the transfer of computer files between a client and server on a computer network.
Why is IT important to distinguish between mechanisms of protection and policies of protection?
Mechanisms determine how something will be done and policies determine what will be done. Policies are changed over time and place to place. Separation of mechanism and policy is important for the flexibility of the system.
What are the mechanism for access control?
Two different types of access control mechanisms are used: user based and host based. That is, one mechanism grants access to a particular user’s account, while the other mechanism grants access to a particular host, or machine.
What is the relationship between computer security and information security?
Differences. Cybersecurity is meant to protect attacks in cyberspace such as data, storage sources, devices, etc. In contrast, information security is intended to protect data from any form of threat regardless of being analogue or digital. Cybersecurity usually deals with cybercrimes, cyber frauds and law enforcement.
Why there is a close relationship between system availability and system security?
Systems have high order of availability to ensures that the system operates as expected when needed. Availability provides building of fault tolerance system in the products. It also ensures the backup processing by including hot and cold sites in the disaster recovery planning.
What are attacks and threats in information security?
A Threat is a possible security risk that might exploit the vulnerability of a system or asset. An attack, on the other hand, is the actual act of exploiting the information security system’s weaknesses. Threats and Attacks that might jeopardize information security can be prevented in a variety of ways.
What is a TCP IP model?
TCP/IP Reference Model is a four-layered suite of communication protocols. It was developed by the DoD (Department of Defence) in the 1960s. It is named after the two main protocols that are used in the model, namely, TCP and IP. TCP stands for Transmission Control Protocol and IP stands for Internet Protocol.
What are the attacks in OSI layer?
In particular, two types of attacks common to the OSI transport layer are SYN floods and Smurf attacks. In an SYN flood, an attacker initiates many connections to a server using a spoofed IP address, not waiting for a connection to finalize. Smurf attacks use malware to overload network resources.
What are the principles of security?
The Principles of Security can be classified as follows:
