I’m not keeping very close track, but it feels
like months since Amazon Web Services (AWS) most recently turned a major
tech industry upside down. But with all their resources and market
power, I’m sure there’s always something interesting cooking in the
kitchens of wherever Amazon’s headquarters happens to be right now.
So let me throw my purely speculative prediction into the silence. As I describe in my Learn AWS in a Month of Lunches book,
AWS has happily replaced your server room with EC2, your SAN and NAS
with S3, your data warehousing with Redshift, and your database with RDS
(and Aurora). They’ve also invented entirely new deployment models:
politely informing you, for instance, that you simply have to serve your
mobile apps via serverless functions (Lambda).
So what’s next? Well how about enterprise routing?
What is enterprise routing these days?
For
decades, large organizations have controlled their internal network
traffic with switches and routers configured by proprietary operating
systems. The hardware is expensive (a single appliance can easily hit
$10,000) and the cost of hiring the trained admins needed to maintain
them can be much higher.
But is all that really still necessary?
These
days your workloads are more likely to live in the cloud than in your
actual office. Even in-house Internet of Things devices can easily be
controlled from the cloud using, for instance, AWS IoT.
I’m guessing that most modern on-premises enterprise routing involves
controlling how people connect to production resources and to each other
(email, VOIP, video) — but even that is more and more likely to be
outsourced to SaaS solutions.
I may be missing something, but I
just don’t see a compelling case for hardware switches here.
Software-defined networking (SDN) should easily be up to the task. Why
not just cover your campus in wireless access points, authenticate users
using Kerberos or Active Directory, and configure your way to
permissions/connectivity perfection.
How AWS can rule the routing world?
Which brings me back to AWS. They’ve already got all the bases covered for authentication (AWS Directory Service) and high-end remote connectivity (AWS Direct Connect). It probably wouldn’t take much for them to extend their networks to your campus. Perhaps they’d allow you to create local VPCs — complete with configurable subnets — that you’d use to organize your local infrastructure.
I’m
imagining a company’s admin logging into the AWS Console to onboard a
couple of new hires from marketing. They’d be added to an AWS IAM
“Marketing” group that’s already got access to Amazon QuickSight
dashboards and streaming data from your public-facing web servers
running on EC2. But the group could just as easily be configured to
allow its members into a database that, for regulatory reasons, must
remain local.
What do you think? Are the days of the proprietary system network admin numbered? Looking for more? You might enjoy my books and Pluralsight courses on Linux, AWS, and Docker-related topics.
Hack The Box (HTB) is an online platform allowing you to test your penetration testing skills. It contains several challenges that are constantly updated. Some of them simulating real world scenarios and some of them leaning more towards a CTF style of challenge. Note . Only write-ups of retired HTB machines are allowed. Devel is described as a relatively simple box that demonstrates the security risks associated with some default program configurations. It is a beginner-level machine which can be completed using publicly available exploits. We will use the following tools to pawn the box on a Kali Linux box nmap zenmap searchsploit metasploit msfvenom Step 1 - Scanning the network The first step before exploiting a machine is to do a little bit of scanning and reconnaissance. This is one of the most important parts as it will determine what you can try to exploit afterwards. It is always better to spend more time on that phase to get as much information as po...
