Be self employed I try and keep up with new techniques and equipment, I work only on network equipments, firewalls etc. I go to all the usual Epxo’s (InfoSec, IPExpo etc.), and do various training course, my current favourites being SANS, although I’ve done lots with Fast Lane ( http://www.flane.co.uk/ ) , Cisco ISE, Wireshark, Juniper, Cisco Nexus etc. All their tutors, like with SANS actually are consultants and still get out in the field, unlike other places where the tutors are just teachers.
I also spend an silly amount of spare time on GNS3 ( http://www.gns3.com/ ) testing theories, I’ve even designed the concepts for a few customer networks using GNS3 so that the cost of buying a full replica pre-production environment.
And other resources I use are CBT Nuggets ( http://www.cbtnuggets.com/ ), an amazing collection of videos, I use it for helping with certification attempts, as a reminder for things and configurations I’ve not used in a while and as you get access to everything they do, I often find myself watching other technologies and things, the MS Excel series has been handy, as has the Powershell videos. I’ve also used them at customer sites to get a grip on issues I come across, especially with servers, VMs etc. Definitely worth the subscription fee.
One other resource that has been useful is Cybrary ( http://www.cybrary.it/ ), it’s free and has some great video series on them.
When I go into company and I see a lack of motivation or maybe it’s just a lack of enthusiasm, I also ask managers why they don’t invest in their staff. The main reason is that they fear that if the staff are trained up they might leave and this investment in them is therefore a risk they won’t take.
I always reply to this with, what if you don’t invest in and train your staff and they don’t leave?
