Security What is typical to be seen by a firewall in front of web facing server

3 Upvotes

As the title says really. What is typically "normal"?

What makes you perk up and look further?

I can see the usual automated recons and corrolating using webstorm centre and other sources.

But sometimes I see a burst of interest to our servers, which makes me think someone has found something interesting enough to cause more probing.

Interested to hear peoples stories.

Other Where can I lease "dirty" (blacklisted/burned) IP blocks at a lower price?

3 Upvotes

Hi everyone,

​Does anyone know where I can rent "dirty" IP blocks at a lower rate?

​I have been searching on Google for a while, but almost all IP leasing providers exclusively advertise clean IP subnets. I also couldn't find much useful information about leasing dirty IP ranges on LowEndTalk or WebHostingTalk.

​Currently, the going market rate for a clean RIPE /24 subnet is roughly $100–$120/month. Because my budget is limited, I am hoping to lease a dirty /24 block for around $50+/month.

​Part of these IPs will be used for legitimate, research-oriented web crawlers. Since this activity could potentially affect IP reputation anyway, I would rather avoid paying a premium for clean space and just lease IP blocks that already have poor or burned reputation.

​Does anyone have recommendations or know of any platforms/brokers offering discounted subnets with existing reputation issues?

​Any advice or pointers would be greatly appreciated!

Troubleshooting Network VLAN Assignment Issue

21 Upvotes

I'm currently troubleshooting a network issue where laptops on the company network are receiving IP addresses from a DHCP scope associated with the Telephony VLAN instead of the Admin VLAN.

No changes have been made in the data room, on the switches, or on the network configuration to my knowledge. However, new devices are consistently being assigned to the wrong VLAN.

Could someone explain what could cause this behavior? What should I check first to identify whether the issue is related to switch port configuration, DHCP relay settings, VLAN assignment policies, or another network component?

Any insights or troubleshooting suggestions would be appreciated.
