Darknet - The Darkside | Ethical Hacking, Penetration Testing & Computer Security HowTo: Find switchport of a MAC Address on Cisco Catalyst Switch | ItsyourIP.com 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. Core1# sh ip arp 192.168.1.15 Protocol Address Age (min) Hardware Addr Type Interface Internet 192.168.1.15 22 0000.1111.1111 ARPA Vlan1 From the above you know the MAC Address of for the device: IP Address : 192.168.1.15 MAC Address : 0000.1111.1111 Now, do a show mac-address command on the core switch or router. Core1# sh mac-address-table address 0000.1111.1111 Legend: * – primary entry age – seconds since last seen n/a – not available vlan mac address type learn age ports ——+—————-+——–+—–+———-+————————– Supervisor: * 1 0000.1111.1111 dynamic Yes 10 Te1/1
Internet Crime Schemes Auction Fraud Auction fraud involves fraud attributable to the misrepresentation of a product advertised for sale through an Internet auction site or the non-delivery of products purchased through an Internet auction site. Consumers are strongly cautioned against entering into Internet transactions with subjects exhibiting the following behavior: The seller posts the auction as if he resides in the United States, then responds to victims with a congratulatory email stating he is outside the United States for business reasons, family emergency, etc. Similarly, beware of sellers who post the auction under one name, and ask for the funds to be transferred to another individual. The subject requests funds to be wired directly to him/her via Western Union, MoneyGram, or bank-to-bank wire transfer. If you believe you may have fallen victim to this type of scam and wish to report it, please file a complaint with us.

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. Alert: Environmental Modified Impact CVSS Base Score Undefined Impact Subscore Exploitability Subscore CVSS Temporal Score Not Defined CVSS Environmental Score Modified Impact Subscore Overall CVSS Score CVSS v2 Vector Not Defined Base Score Metrics The base metric group captures the characteristics of a vulnerability that are constant with time and across user environments. Exploitability Metrics Access Vector (AV) This metric reflects how the vulnerability is exploited. Local (AV:L) Adjacent Network (AV:A) Network (AV:N) Access Complexity (AC) High (AC:H) Specialized access conditions exist. Medium (AC:M) Low (AC:L)
National Vulnerability Database Home 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. Just to be clear, we're talking about product security as opposed to security products. First, let's address the topic of receiving information about product security. Provide an easily identifiable role email address specifically for product security issues In our experience, it's extremely beneficial for the vendor to provide a role email address (e.g., a shared mailbox or an alias) for receiving information. Note that we haven't provided any recommendations here about what vendors should actually DO when they receive product security reports. Because communication should be a bidirectional process, let's next consider the publication of product security information.
CSIRT, Computer Security Incident Response Team NIST.gov - Computer Security Division - Computer Security Resource Center 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. With policies and procedures, it is essential to be proactive rather than reactive. That may be a simplistic scenario where the company is out a thousand dollars for a laptop, but it illustrates a point. What if, instead of being out a thousand dollars for a laptop, you were instead out tens or hundreds of thousands of dollars in fines after a cardholder data breach? As far as information security, every organization will have a unique set of foundational policies. How then, do we determine what basic policies we need? Careful readers will note that I slipped in mention of another document, the visitor log.
Blocking Unwanted Parasites with a Hosts File What it does ... You can use a modified HOSTS file to block ads, banners, 3rd party Cookies, 3rd party page counters, web bugs, and even most hijackers and possibly unwanted programs. This is accomplished by blocking the connection(s) that supplies these little gems. The Hosts file is loaded into memory (cache) at startup, so there is no need to turn on, adjust or change any settings with the exception of the DNS Client service (see below). Windows automatically looks for the existence of a HOSTS file and if found, checks the HOSTS file first for entries to the web page you just requested. The 0.0.0.0 (prefix) is considered the location of your computer, so when an entry listed in the MVPS HOSTS file is requested on a page you are viewing, your computer thinks 0.0.0.0 is the location of the file. Example - the following entry 0.0.0.0 ad.doubleclick.net blocks all files supplied by that DoubleClick Server to the web page you are viewing. Simply follow the instructions for Windows 10/8
Information Security Policies and Procedures Part 1 Note: This is part of an ongoing series on documentation development. Policy writing can be a daunting task, and one for which many are not overly enthused. However, Policies and Procedures are an integral part of any information security program. Not only do they provide direction and accountability, many specific policy elements are a requirement of specific laws, regulations, and/or standards. Before we get started, there are a few things that are important to know.Policy sets are different in each environment. There are other factors that will affect information security policy development as well. It is essential that different departments work together to ensure that policies work in concert and do not contradict each other. It is also essential to determine the audience for any given policy. Network Security Policies, Access Control Policies, and System Access Logging and Maintenance Policies will have IT departments as their audience.
