Quick-Tip: How to Make SNMP More Secure

TruePath Technologies Quick Tips: How to Make SNMP More Secure

People are always asking us about SNMP and security.

We recently ran across this quick tip from Tony Fortunato of Lovemytool.com and knew we had to share it.

While working with a client recently, Fortunato had a conversation about potential security risks when enabling SNMP V2. He explained that, while the security risks are likely true, it depends on how you configure it combined with how your network behaves with it. And, ultimately, it’s a temporary solution which can simply be turned off after it is no longer needed.

As Fortunato explains, there are options for making SNMP more secure:

I started to draw a simple network diagram of his network and identified that his firewalls don’t allow SNMP from the internet so that possible issue is covered.

I then showed him some Cisco configuration commands to prevent SNMP traffic from devices and networks that we can specify.

The Cisco commands look like this;

snmp-server community notpublic RO 99

The above command enables and configures the snmp service with a read only string of notpublic. The 99 refers to an access list where we control what devices have permission to perform SNMP queries.

access-list 99 permit

With this command we define that access-list 99 only allows devices from subnet

You should test by performing an SNMP query with your network management tool to ensure that is has access but you should ensure that unauthorized devices do not have access.

You can get an idea if your access list is working as well with the following Cisco command;

show access-list 99

Standard IP access list 99

10 permit, wildcard bits (684 matches)

The same points apply to Microsoft (plus WMI) or other devices. 

Fortunato goes on say that it’s important to determine how you can get more data from your devices while troubleshooting or baselining.

We hope you enjoyed this quick tip on SNMP and security!

Worldwide Business with Kathy Ireland Features OP5 This Sunday, 3/19, at 5:30 P.M. EST


Don’t miss it!

This Sunday, 3/19, at 5:30 P.M. EST our friends at OP5 will be featured exclusively on Worldwide Business with Kathy Ireland.

OP5 LogoOP5 is an industry-leading developer of Open Source Management solutions. They offer
enterprise-class software for monitoring and administration of the whole IT infrastructure, from hardware and software to virtual and cloud-based services.

As the premiere provider of OP5 services in North America, TruePath is excited to see our friends CEO Jonas Vestin and CTO Jan Josephson of OP5 discuss with Kathy how companies can take control of their IT monitoring in today’s fast-paced era of digitalization.

From the OP5 blog:

“OP5 wants to reach a broad audience in the US to raise the issues of monitoring related to “the cloud” and “the new age of digitalization”.

…Many people forget that in the basement there has to be servers handling the digitalization. And these servers and networks need to be monitored in the most competent way possible. If a server goes down, the business might suffer tremendously. The Forrester study also outlines that natural disasters is the least of your worries. The top reasons for downtime are related to IT hardware (43%) and network (37%).

…By monitoring your IT, you can get control over everything from the smallest switch to the cloud. Knowing where you are, where you want to be and measure the status in between is a key to be competitive and provide a stable, secure high capacity IT. If a problem arises somewhere, the average IT organization of today will spend ten times more time finding the problem than fixing it. This is a challenge that we as a company solve for our customers.”

TruePath’s Tools to Take with You into 2017

TruePath Cool Tools: A Series for Us All

In a world that is constantly evolving, especially when it comes to the Internet, the Internet of Things (IoT), The Internet of Everything (IoE) and just about everything else in the tech industry, it’s hard to know which programs and products are most efficient or worth the download. Every time we enter the app store, we are bombarded with new products being advertised that can improve our productivity, organization and lifestyle but which ones are worth our time and most importantly, our money?

It’s time we took matters into our own hands. Our team of experts at TruePath Technologies, are bringing you a new webinar series unlike any you’ve seen before.

This 5-part webinar series will introduce you to tools we use every day and consider “cool”. They will differ in types, such as password safety, ways to increase your productivity, screen-casting and many, many more! Please note, we aren’t getting paid to advertise and promote these products. On the contrary, we are sharing them because we WANT you to know which tools are worth looking into. It’s time we shared the 2016 Awarded “TruePath Cool Tools”

During each webinar, you can expect to see how the tool or platform works, what it’s used for, why we like it and the cost (if any). Each webinar will last around 30 minutes, making them lunch break approved!
