HowTo: Find switchport of a MAC Address on Cisco Catalyst Switch If you have a big network with multiple Access Switches connecting to the core switches or routers then tracing a device like a PC or a laptop for troubleshooting or security purposes is one of those tasks that you often end up doing. This is not a difficult task but can certainly be time consuming. Lets start with an IP address on hand. If you have an IP address on hand quickly ping and check if the device is pingable. If yes, then simply logon to one of your core switches or routers and do a simple sh ip arp Metasploit Metasploit From Wikibooks, open books for an open world Jump to: navigation, search
National Vulnerability Database CVSS Scoring This page shows the components of the CVSS score for example and allows you to refine the CVSS base score. Please read the CVSS standards guide to fully understand how to score CVSS vulnerabilities and to interpret CVSS scores. The scores are computed in sequence such that the Base Score is used to calculate the Temporal Score and the Temporal Score is used to calculate the Environmental Score.

Linux and Open source Understanding Nmap Commands: In depth Tutorial with examples - Vimperator Article by James Hawkins As we all know, Nmap (Network Mapper) is a stealth port scanner widely used by network security experts (including forensics & Pen-testing Experts). In this article we’ll see the different types of Nmap Scans, its techniques, understanding the purpose and goals of each scan , its advantages or disadvantages over other scanning tools, which could be better at evading firewalls & IDS (To a certain extent) and much more. In this first part, I have made my best to explain the basic scanning techniques, Host discovery options, port scanning options, techniques used in detecting Operating system & services running on the system. i also give Nmap as already installed on your system. Let’s start with one of the most basic and default scan, the one without using any parameters.
CC Blog: Recommendations to vendors for communicating product security information Hi, this is Chad Dougherty of the Vulnerability Analysis team. One of the important roles that our team plays is coordinating vulnerability information among a broad range of vendors. Over the years, we have gained a considerable amount of experience communicating with vendors of all shapes and sizes. Based on this experience, we can offer some guidance to vendors about communicating product security issues. Linux and Open source PortSpoof – An interesting anti-snooping tool for Linux - Vimperator Fool those who try to portscan your system! The Portspoof program is designed to enhance OS security through emulation of legitimate service signatures on otherwise closed ports. It is meant to be a lightweight, fast, portable and secure addition to the any firewall system or security infrastructure. The general goal of the program is to make the port scanning software (Nmap/Unicornscan/etc) process slow and output very difficult to interpret, thus making the attack reconnaissance phase a challenging and bothersome task I’ve found the concept behind this small program really interesting : instead of close all your ports with a firewall deceive the real ports, thus annoying the guys who are running portscan versus your server/computer. The Portspoof program primary goal is to enhance OS security through a set of techniques that will slow down and keep your attackers out from staying low profile during their reconnaissance against your system(s).
Information Security Policies and Procedures Part 2 This is part of an ongoing series on documentation development. Please be sure to read the previous posts in this series: Part 1Knowing which policies are necessary in your environment can be a challenge. Most organizations will have at least some formalized policies. Many of these are in response to legal requirements (HR policies) or specific incidents. After someone leaves their laptop in the car trunk for 6 hours on a 100 degree day, a policy on the care of equipment is generally issued.
