I find that sometimes the issue is that the scope which we have at around 8 days does not automatically purge when the time is up even though it should. Then, we get stale reservations causing a particular vlan scope to fill up. It seems strange but the quickest resolve is to reboot the affected VM and zap the scope…

Helpful and informative. Thanks!

Good discussion. I found it educational and informative.

Handy reference chart in your post. Thanks, blameit! Excellent points.

I was probably 3 years into support for computers when my Mom HAD to learn to use an IBM AT computer and in particular she had to give up her IBM Selectric2 typewriter and move to Word Perfect. That has began the lifetime of computer support. Fortunately, she does not open any emails that she does not know, she does not…

Good points on TFTP

I could see that being beneficial.

I wish we could get to 4/5 training. If it is not convenient, it will be deemed unnecessary and get in the way of their being able to perform their duties. Even though, when something goes awry that the time required to correct it far exceeds the time upfront.

Yes, and I always used the argument. How much will it cost the business to not ensure working backups. Then, I usually got my budget If anyone has had the joys of being audited (SOC, etc). Backup and restore is a crucial item.

A great article, I agree. Thanks for posting.

Interesting post.

This was a good article. Dated, but relevant. 

I found it interesting reading.

Thanks for the information!

I think we are going to keep hearing about more and more breaches. Security needs to become the highest priority.

I wonder around the office and what do I find. I am the only with the NMS open. The others only open when they Need something. I am working on the training side to change that. Also, if nodes are not kept current, then it quickly falls apart. Good post!

Worthy information to keep the toolbelts filled.

Helpful!

Thanks!

Costs are costs are costs. The layers of the security onion are costly but are necessary. Thanks for the post. I will go back and read the rest of the posts that I missed.

Good post. Could definitely use more of this type of post. Thanks for sharing.

Thanks!

Interesting article. Thanks for sharing!!!!

We experience the highest hits against port 22 and 3389, followed by 80. The data suggests the country of origin and I would say that those pretty well match what we have. We implemented a SIEM solution that is fed syslog, event logs, and net flow data. It provides some real-time analysis of the items mentioned in the…

Good information. Thanks for posting.

Looks like nice tool to add to the toolbelt!

Interesting article

This article just made me smile. I am in the process of a cisco refresh migrating to 3850 and now I am looking forward to getting the details that netflow offer to assist in the analysis of bandwidth and connectivity issues. Presently, I have to run MRTG against a particular switch to gain insight into the port interface…

I have not been an exchange admin for 15 years or so. Good information presented. I too have not seen the webinar but looking forward to it soon.

Interesting.
