Honeypots are a security tool that is used to protect networks and systems from malicious attacks. They are designed to mimic the behavior of a real network or system, making them appear attractive to potential attackers. When an attacker targets a honeypot, they are led to believe that they have successfully breached a valuable asset, when in reality, they are interacting with a decoy. Honeypots are a valuable tool for security professionals, as they can provide valuable information about an attacker’s tactics and motivations, as well as alerting the security team to potential threats.

HTTP request tracing middleware

Request-based tracing provides a way to determine what exactly is happening with your requests and why.

It is handy when you want to reproduce and understand the problem that you are experiencing.

Install and configure a tftp server

Bogdan Ungureanu

TFTP (Trivial File Transfer Protocol) is a simplified version of FTP (File Transfer Protocol). It was designed to be easy and simple. TFTP leaves out many authentication features of FTP and it runs on UDP port 69. As it is very lightweight, it is still used for different purposes.

IP Based rate-limit middleware using go.uber.org/ratelimit

Bogdan Ungureanu

If you’re running a HTTP server and want to rate limit user requests, and most of the frameworks are providing their own middleware.

But if you want something simple and lightweight – or just want to learn – it’s not too difficult to roll your own middleware to handle rate limiting.

DHCP explained

Bogdan Ungureanu

DHCP stands for dynamic host configuration protocol and is a network protocol used on IP networks where a DHCP server automatically assigns an IP address and other information to each host on the network so they can communicate efficiently with other endpoints.

Enable DHCP snooping on SG3XX layer 3 switches

Bogdan Ungureanu

DHCP snooping is a security feature that acts as a firewall between untrusted hosts and trusted DHCP servers.

To protect your network against rogue DHCP servers and remove malicious or malformed DHCP traffic, the DHCP snooping needs to be configured on LAN switches to block the unwanted traffic.

Identify and Remove Rogue DHCP Server

Bogdan Ungureanu

A DHCP (Dynamic Host Configuration Protocol) server is a networking service that automatically assigns IP addresses to devices on a network. This is essential for modern networks to function efficiently without manual IP address configuration.

A “rogue” DHCP server is one that has been set up without the network administrator’s knowledge or permission, and can cause serious conflicts and connectivity problems on the network.
