Network address translation (NAT) is very simple in concept. As packets pass through some network device—typically a firewall, router, or load balancer—either the source or destination IP address is changed. Then packets returning in the other direction are translated back to the original addresses. In some cases both are changed at once, which is called “twice NAT” in some documentation.

Have you ever been in the middle of a breach remediation? While the first priority is handling the initial breach, after it’s resolved the priorities quickly change to mitigating future attacks.

Why SaaS could make your IT skills irrelevant. Headlines like this are scary, right? Well, that article was from back in 2008. Do you feel irrelevant? No, you say? That’s what I thought… There’s no binary transition point when a skill becomes totally irrelevant. IT is always evolving. This shouldn’t be scary. Imagine if you hadn’t evolved your skills since 2000. Or 2010. What are the things you’d be behind on now?

A significant portion of companies have vulnerabilities in their network management practices.

If this past year has proven anything, it’s that making long-term predictions can be a challenge. After all, who would have predicted a large portion of the workforce would be fully remote and we’d be staying six feet away from each other in grocery stores for most of the year?

The challenge is putting all of those pieces together to see the bigger picture.
