I find a lot of value in the videos on this site but another resource I used was Professor Messer. He has some security+ notes and has some free training classes monthly. I think itpro.tv should also have those as well. I find them very valuable.
I would like to know the benefit of applying an access to a switch instead of applying it to a router?
On switches you can run two types of ACLs:IP address ACLs MAC address ACLs
If you need to control access between devices within the same subnet (or VLAN) for example.
I understand it can only block IN, but wouldn't that be a better choice instead of using a router?
It depends on what you need. the ACL on routers is normally between VLANs or other networks. So each has it's place. Also, it depends on the level of granularity needed.
Configuring on both may be needed but can cause confusion if you don't remember that ACLs have been configured on both.
Thank you again for your quick response.
In the end NetInstaller was not what I was looking for and Netrestore is a non starter as it requires extra cables I dont have at hand not to mention the need to move heavy equipment from one office to another just to connect them phyically togeather. Also many complained but I could not verify that is struggled to deploy software like Adobes products or Office for Mac in it image.
Instead I have installed DeployStudio from deploystudio.com.
This clever free software enables me to create a deployable image of a mac over the network and deploy as easily as if I was using NetInstaller/NetRestore. I hope this helps any one else who finds this Question.
IT Service Managment
Hey, thanks for the reply @Ronnie-Wong, I'll probably have to skim the Foundations course to see.
I just finised the Event Management episode. Very good information here. The only experience I had before was the ad-hoc things we do for Event Management (and monitoring).
Some key points for me:There are three specific event categories (set by ITIL) The Event Trigger is the response to the event Key to someting being an event is that it is logged somewhere Monitoring is not the same as Event Management
As with Incident and Problem management, the overall goal is the minimize disruption to the business.
