all your videos are helping me to gain the knowledge and even to pass my exams .thanks a lot

[@mrao2137]

Preventing from denial of services Dos and DDoS attacks is ensuring availability of data. How is it non repudiation? Non repudiation is user cannot deny that he has sent data. It is encryption or digital signature principle.

[@jagdeepsingh-tv4ty]

M Rao u r right non repudiation is not ddos

[@dopamine8704]

Yes this is right anwser

AAA concept authentication authorisation and accountability are access control principles. Just wanted to know how are they called as security services. Access control is security service but AAA is security principle

[@SRIRAJS-om2qg]

Sairam. Nice presentations.. I have seen the introductory lecture and the lecture on attacks also. In this lecture only I have a comment to make. When googled... Non repudiation is given as "Nonrepudiation is the assurance that someone cannot deny something. Typically, nonrepudiation refers to the ability to ensure that a party to a contract or a communication cannot deny the authenticity of their signature on a document or the sending of a message that they originated"... Meaning that sender may be later denying the fact of having sent the data... Also... You have not talked about AVAILABILITY(A)... In many other lectures I have seen that CIA are most essential in the Data security... ANYWAY... GREAT WORK...

[@sundeepsaradhi]

[@mrao2137]

Confidentiality, Integrity and availability of data is security principle and not security services. Can you please explain how CIA is security service?

[@nitinneo7]

These are the 5 broad categories of Security Services under X.800. They can further be classified into many sub-categories. And the mechanism used to achieve these is a different topic. These do come under Security Services.

[@nightshaden351]

M Rao is not data principle it's under X.800 security services and you have 2 types of confidentiality - Traficflow confidentiality - Data confidentiality They are all services

[@kvaniyesho8862]

Sir, when will you explain mechanisms

[@basantsingh8605]

sir very nice sir, please share some video for cyberark too

[@sundeepsaradhi]

hi basant i am not aware of that but give me some time i will get some information and i will do the video. thanks for your interest towards our channel and share my sessions with your friends and subscribe to our channel.Keep following our channel.

[@rajeshbaddam2467]

Thank you sir. can you explain the protocols lecture

[@maqsoodqambrani1367]

Thank you, Sir... I also want to know that What is X.800? and also explain Do we need to implement all the X.800 security services in any application?

[@sundeepsaradhi]

hi maqsood it describes the reference model for Open System Interconnection (OSI) yes we have to implement all the services in application.

[@maqsoodqambrani1367]

thank you sir.

[@arunendraprakashdubey7904]

thanks sirrrrrrrrrrrrrrr

[@sundeepsaradhi]

thank you prakash

[@luciferunexpected676]

Difference between Authentication or Authorization is In authentication server authenticate that the user is genuine or not also we can say that it is process of verifying the user and in Authorization the server setup a rule for user that how much data the user can access or is he have permission to change something in that program .

[@lakshminarayanag4150]

VERY HELPFUL..

[@sundeepsaradhi]

hi lakshmi narayana thanks for your interest towards our channel and share my sessions with your friends and subscribe to our channel.Keep following our channel.

[@BrijeshYadav-vl7bj]

Hello Sundeep, Non-Repudiation doesn't mean preventing denial of service. It means enough provision or evidence so that authentic user cannot deny his past action at a later date. For example..I cannot deny to banks about my financial transfers in online bank accounts..because bank have enough evidence to show it was me who did those transactions.

[@sundeepsaradhi]

hi Brijesh thanks for the correction and keep on supporting our channel.

[@kgnikhil2081]

sundeep sir, I want to know about the denial service. the question is when the third party is disrupting at the server level in the name of sender. then how the dataflow between sender and receiver is done?. after disruption in the server it is sent to the server or receiver?

[@venkatesasrikanthdhulipala9486]

Sir please upload ethical Hackings videos

[@prateiksehitia17]

Sir, please clear your concepts of non-repudiation

[@sumanthdommeti256]

Sir what abt Sequrity mechanism of cryptography

[@initalAS]

love u sir

[@-R-KolaNikhil]

mechanisms and services also same ha sir

[@prateekmandal1983]

Although the scope of content is fine I think some definitions are not correct e.g. Confidentiality is not security (which is a very broad term), it simply means that data, objects and resources are protected from unauthorized viewing and other access. Integrity means that data is protected from unauthorized changes to ensure that it is reliable and correct. And like others have pointed out non-repudiation is not denial of service at all. Just want the viewers to get the right info.

[@shilpanr]

sir can u post a video on DES,Triple DES and AES algorithms

[@sundeepsaradhi]

hi shilpa definitely i will upload every concept of Information Security.Maximum today or tomorrow i planned a video on DES.
