next → ← prev Show This article is going to be very interesting and important for readers that are interested in cyber security. In this article, we are going to discuss two major types of security attacks that are Active attack and Passive attack. Hope this article will be informative to you, and give you the sufficient information about Active attack, Passive attack, and their comparison. So, without any delay, let's start our topic. What is a Security attack?Security attacks jeopardize the system's security. These are the unauthorized or illegal actions that are taken against the government, corporate, or private IT assets in order to destroy, modify, or steal the sensitive data. They are further classified into active and passive attacks, in which the attacker gets unlawful access to the system's resources. Active attacksIn active attacks, the attacker intercepts the connection and efforts to modify the message's content. It is dangerous for integrity and availability of the message. Active attacks involve Masquerade, Modification of message, Repudiation, Replay, and Denial of service. The system resources can be changed due to active attacks. So, the damage done with active attacks can be harmful to the system and its resources. In the below image, we can see the process of active attacks.  In active attacks, the victim gets notified about the attack. The implication of an active attack is typically difficult and requires more effort. Active attacks can be prevented by using some techniques. We can try the below-listed measures to prevent these attacks -
Passive attacksIn passive attacks, the attacker observes the messages, then copy and save them and can use it for malicious purposes. The attacker does not try to change the information or content he/she gathered. Although passive attacks do not harm the system, they can be a danger for the confidentiality of the message. In the below image, we can see the process of passive attacks. Unlike active attacks, in passive attacks, victims do not get informed about the attack. It is difficult to detect as there is no alteration in the message. Passive attacks can be prevented by using some encryption techniques. We can try the below-listed measures to prevent these attacks -
Active attack v/s Passive attackNow, let's see the comparison chart between Active attack and Passive attack. We are comparing both security attacks on the basis of some characteristics.
Next TopicDifference between ← prev next → Is denial of service an active attack?A Denial-of-Service (DoS) attack is an attack meant to shut down a machine or network, making it inaccessible to its intended users. DoS attacks accomplish this by flooding the target with traffic, or sending it information that triggers a crash.
What is meant by a denial of service attack?"Denial of service" or "DoS" describes the ultimate goal of a class of cyber attacks designed to render a service inaccessible. The DoS attacks that most people have heard about are those launched against high profile websites, since these are frequently reported by the media.
What are the active and passive attacks?In an active attack, System resources can be changed. While in passive attack, System resources are not changing. Active attack influences the services of the system. While in passive attack, information and messages in the system or network are acquired.
Which attack is passive attack?A passive attack is a network attack in which a system is monitored and sometimes scanned for open ports and vulnerabilities. The purpose of a passive attack is to gain information about the system being targeted; it does not involve any direct action on the target.
