Hello, I am looking at the basics of the network and I have a question. 1)In phase 1 of an ipsec tunnel there is a key What does this key correspond to 2)In phase 2 there's another key, what does it correspond to 3) Despite my numerous internet searches, I still can't understand what IKE and ISAKMP are in simple terms 4) why do we say that the security parameters are negotiated between the 2 peers when we define them manually? Thank you very much.
After looking so many videos I am still not clear why there is need of two phases. If already secure tunnel established in phase 1 then why there is need of phase 2
To make exchange of information required in the second IKE phase more secure, the first phase establishes a tunnel. And that tunnel is also secured. Two layers make it more secure.
there is only one key - following video demonstrates site-to-site VPN in packet tracer showing configuration of the required key ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-TO4Spdmb4os.html
Sir, the video is great for understanding but can you please proofread, also prepare notes and read from there rather? The representation is good. Kindly fix this in the feature video, ESP - Encapsulating Security Payload. I am going for an interview and when doing a quick recap, have noticed it
It seems like they are the keys being used during both of the phases of IKE help.fortinet.com/fos40hlp/43/wwhelp/wwhimpl/js/html/wwhelp.htm?context=fgt&topic=autokey&single=true
Explained wrong...AH is not providing integrity..i suggest do not refer this video explained wrongly in multiple points.. like in phase 5messages are thr..... it's wrong
first at all this is an amazing video about IPSEC. But can somebody explain this: On first slides is described what ipsec provides (Integrity, auth, confidentiality, key management) than what ipsec negotiating (AH,ESP,IKE). Than on on IKE Slides there is HAGLE, which is same thing as ipsec doing in two phases. IPSEC = IKE? IKE=IPSEC? IKE using IPSEC or IPSEC using IKE?
