IT student here. Genuinely curious: could you explain why this is a fundamental error?
SNMP is used for internal management/monitoring of network-enabled devices, which you don't expose to the public internet. The SNMP supported on old PIX is SNMPv1/SNMPv2 which sends the community string in plaintext, and the reply is similarly unencrypted, so its basically the same security level as telnet or regular http (none).

Isn't it interesting how JETPLOW is an anagram for JEWPLOT?

#26re: EXTRABACON If you have SNMP listening on a public ipv4/ipv6 interface of a firewall (I don't care if it's an EOL/EOS PIX or not), you have done something fundamentally wrong from the start. As a network engineer seeing something like this in a business customer's equipment would cause me to seriously reconsider all other decisions/security configurations made by a predecessor or third party contractor.

Having a port listening on the internet means you've exposed (usually) tens or hundreds of thousands of lines of code to anyone with an internet connection. One vulnerable line of code or mis-configuration could be an entry point into your network for an attacker.
The key then, is deciding what absolutely needs to be exposed. If you run a website, you're going to need to expose your web server to the internet. Need access for remote workers? You'll open up a VPN. There are a bunch of things that generally have no place being exposed to the internet: SNMP, SMB, afp, RDP, Telnet, Any admin console, etc.

It's just poor grammar. Here's the fixed sentence, replacing a confusing proper noun: "PROPERNOUN Cisco software is signed using secure asymmetrical (public-key) cryptography in newer platforms [that] prevents these types of attacks."

I agree but if there is one lesson I've learned, its that often when you find such environments it is due to failure of the management/execs to properly support the IT team, so they cut corners, halfass it, or hire contractors as you mentioned. True it shouldnt be done, but if you are selling equipment to a business who has had this failing, its just something to be aware of. Im so damn tired of companies underfundin…

#29Is this a standard naming convention for exploits?
