Check your SNMP security
1 comment- IT TOPICS:Hardware, Management, Networking, Security, Software
Here's a good axiom to follow: By default, no device or system on your network is secure.
What do I mean by this? I mean, when you first plug in and turn on a device, just about any networked device, you must do work to secure it as the default settings are almost always not secure.
This goes for printers, switches, firewalls, laptops, desktops, servers, networked storage devices, etc.
For instance, a lot of devices these days come with Simple Network Management Protocol (SNMP) installed and running. What's even worse for the security conscious tech person, is that the Read and Write security "community" strings for SNMP are set to the default of public and private, respectively.
This is a pretty serious security hole that can be used by a hacker, once inside your network, to catalogue systems on the network or, depending on the hacked device's implementation of SNMP, do various other nefarious things to include taking control of an insecure system and using it to commit further attacks.
So do yourself a favor. Disable SNMP on all your networked devices if you aren't using it, or if you are using it, make sure you update the device with the latest patches and or firmware related to SNMP security and make sure you change the community strings from the defaults to something a lot more secure.
