Calculate the Window of Vulnerability There are four parts to be considered when calculating the WoV. These four parts are the Discovery-Time, Exploit-Time, Disclosure-Time, and Patch-Time. All four of these must be looked at and evaluated as a part of calculating the amount of time that the server will be vulnerable for. Discovery Time is the earliest date that vulnerability is discovered and recognized to pose a security risk. The discovery date is not publicly known until the public disclosure of the respective vulnerability. Exploit Time is the earliest date an exploit for vulnerability is available. We qualify any hacker-tool, virus, data, or sequence of commands that take advantage of vulnerability as an exploit. Disclosure Time is the first date vulnerability is described on a channel where the disclosed information on the vulnerability is freely available to the public, or is published by trusted and independent channel and has undergone analysis by experts such that risk rating information is included. Patch Time is the earliest date the vendor or the originator of the software releases a fix, workaround, or a patch that provides protection against the exploitation of the vulnerability. Fixes and patches offered by third parties are not considered as a patch. A patch can be as simple as the instruction from the vendor for certain configuration changes. Note that the availability of other security mechanisms such as signatures for intrusion prevention systems or anti-virus tools is not considered as a patch in this analysis. Unfortunately, the availability of patches usually lags behind the disclosure of vulnerability. Each major vulnerability and time it takes to fix is what is used to calculate the WoV. So from the day it was found till the time the patch can be installed will be about four days of unsecured vulnerability. Then...

...Steven Schmidt 7/8/2013 CALCULATE THE WINDOW OF VULNERABILITY A security breach has been identified within a small Microsoft workgroup LAN. The workgroup consists of three primary workgroups which contain group membership lists of users within the Active Directory infrastructure that currently exists on the SMB Server that is located within the confines of the LAN structure. The security breach, which is defined as any event that results in a violation of any of the CIA (confidentiality, integrity, availability) security principles, was caused by the SMB server being accessed by an unauthorized user due to a security hole that was detected by the server software manufacturer the previous day. The security patch will not be available until possible as long as three days, but hopefully within that timeframe. In addition, the LAN administrator needs at least one week (minimum) to download, test, and install the patch. To calculate the Window of Vulnerability (WoV) for this security breach, the following timeline will be used as a guideline to determine the basis for calculation: However, first it is important to understand the variables considered in this timeline formula. The WoV is the period within which defensive measures are reduced, compromised, or lacking. The WoV covers a timeline from the moment a vulnerability is discovered and identified by the vendor. It also includes the time taken to create, publish, and...

...| Unit 2 Assignment 1 | UNIT 2 ASSIGNMENT 1: Calculate the Window of Vulnerability | | Chris Riddle | 12/22/2015 | Instructor: Mr. Sprinkle | To calculate the WoV, we must consider the following (Stefan Frei, 2013): 1. Discovery Time is the earliest date that a vulnerability is found and known to pose a security risk. 2. Exploit Time is the earliest date an exploit for a vulnerability is available. 3. Disclosure Time is the time to make security information available to the public in a standardized, understandable format. The publishing channel must satisfy the following requirements: a. Free Access: the information must be made to the public free of charge. b. Independence: the information must be published by a widely accepted and independent source. c. Validation: the vulnerability has been analyzed by security experts & includes risk rating information. 4. Patch Time is the earliest date the vendor or the originator of the software releases a fix, workaround, or a patch that provides protection against the exploitation of the vulnerability. The time between each of these areas or, the vulnerability’s lifecycle is divided into three risk areas. Black Risk - during the time from discovery to disclosure, only a closed group is aware of the vulnerability. Gray Risk - during the time from disclosure to patch the user of the software waits for the vendor to issue a patch. White Risk - the time from patch......

The WoV is the period within which defensive measures are reduced, compromised, or lacking. The WoV covers a timeline from the moment vulnerability is discovered and identified by the vendor. It also includes the time taken to create, publish, and finally apply a fix to the vulnerability. It is also important to explore the device(s) that were targeted by the attack. In this instance, being the SMB server within the LAN. The SMB server utilizes an application layer network protocol, which can run atop the session layer. It provides shared access to files, printers, serial ports, and network nodes (workstations, laptops, desktops, etc.) and provides a client/server......

...Eric Mcknight 7/6/2012 Unit 2: Assignment 1: Calculate the window of vulnerability. To calculate the window of vulnerability (WOV) we will first need to know the amount of time It will take to get a working solution. In this case, we need a patch to solve the issue. We already know that it will take Microsoft 3 days to get a patch out to us. So, we can start with three days. After that, we need time to test the patch, and publish it out to the active directory update servers. This will usually take a few days according to the book. After it is all tested on the equipment, we need to push out the update to all of the client computers and servers. This will usually take a day or so. Also, depending on if the IT staff works on the weekends to solve the problem that will add another two days to fix the problem. So, to add it up, It takes three days to get the patch, Up to five days to test the patch, and another day or two to publish the patch out to all of the client computers. All in total, this will take around a week to solve this issue. My personal opinion is any IT personal that takes a WEEK to solve a major security breach should be fire. Personally, I would put immediate measures in place to solve the issue such as blocking the mac address, immediately writing scripts and programs to detect intrusions in the hole, and block out the attacker. Taking more than a day or two for testing is major overkill for fixing a major hole. But, that is my...
