This process is also called "cryptanalysis". There are main two types of security attack in cryptography: Passive Attack and Active Attack. In this video, I have explained Active attack in network security. There are four types of active attack: Masquerade, Replay Attack, Modification of message, Denial of Services. Masquerade: A masquerade take place when an attacker pretends to be an authentic user. Authentication sequence can be captured & replayed after a valid authentication sequence has taken place. It generally done to gain access to a system, or steal information from system. Replay Attack: Replay involves the passive capture of data unit and its subsequent retransmission to produce an unauthorized effect. A replay attack is also known as playback attack where attacker repeatedly keeps on transmitting valid data again and again to make the network jam or delayed the transmission of data. Modification of message: Some portion message is altered, or that message is delayed or recorded to produce unauthorized effect. When content of message modified after sender sends it but before it reaches to concerned receiver, such type of attack is called modification of message. Denial of Services: Denial of service attack means making the network unavailable for the user those who want to communicate securely. Flood the entire network or server with traffic until shutdown occurs because if overload. This attack may have a specific target. Other form of this attack is disturbing an entire network, either by disabling the network or by overloading with messages so as to degrade performance. 0:00 Introduction 0:08 Types of security attack in network security 0:17 Types of active attack in network security 0:33 Masquerade 1:39 Replay Attack 3:17 Modification of Message 4:42 Denial of Services If you like my video contents, please LIKE, COMMENT, SUBSCRIBE & SHARE with your friends. -------------------------------------------------------------------------------------------------------------- Check out our other video on our channel page Principle of Application Layer https://youtu.be/bj33lPUCpR8 Cookie explain using animation: https://youtu.be/ZaC5gW5UKJQ Persistent HTTP vs Non Persistent HTTP: https://youtu.be/8FuOereXcoc Email: https://youtu.be/UkQ_ascb6PA -------------------------------------------------------------------------------------------------------------- You can always connect with me at: Follow my blog: https://www.chiragbhalodia.com Like my Facebook page: https://www.facebook.com/chiragbhalodia25 Follow me on Instagram: https://www.instagram.com/chiragbhalodia.25 Follow me on twitter: https://twitter.com/chiragsbhalodia Subscribe me on youtube: https://www.youtube.com/c/ChiragBhalodia -------------------------------------------------------------------------------------------------------------- Playlist available on my channel: Network Security (CNS, INS, IS): https://youtube.com/playlist?list=PLzQqHxFtQGyfiYWaDnasLdy1JPK3JS06o Computer Network (CN) with animation: https://youtube.com/playlist?list=PLzQqHxFtQGycfs9Vn8BYy0ic0wh-oL9UC VFX Animation & Fun Videos: https://youtube.com/playlist?list=PLzQqHxFtQGyd9esvf-t5XYOKhxQS0tDWx Comupter Organization & Architecture (COA, CA, CO): https://youtube.com/playlist?list=PLzQqHxFtQGyd-uDzS9vov8hJfm03X_SzC Assembly Language Programming: https://youtube.com/playlist?list=PLzQqHxFtQGyeTa82xQyceYxaf-iyZBICw Computer Graphics: https://youtube.com/playlist?list=PLzQqHxFtQGycg_TJBA6uFGDLwbotjs68h #chirag_bhalodia #chiragbhalodia #network_security #cryptography #Types_of_security_attack #Active_Attack #Types_of_Active_Attack #Masquerade #Replay_Attack #Modification_of_Message #Active_attack_in_cryptography #Security_attack_in_cryptography Keep learning, keep supporting 🤝✨💯
