...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 finally apply a fix to the vulnerability. It is...

... it is the operating system that governs how any application actually reads from, or writes to, a physical disk. Consequently, the operating system is a prime candidate for attack and a valuable resource to protect. From an attacker's point of view, a compromised operating system provides easy access to protected information. Compromising operating system controls gives the attacker the ability to remove evidence of attacks and "clean up" any leftover log entries or other traces of the attack. A secure operating system is the basis of a secure environment. In this chapter you will learn about the Windows operating system architecture and controls to ensure system security. You will also learn how attackers search for, find, and exploit operating system vulnerabilities. With the knowledge of how attackers operate you'll be able to identify and implement the right controls to secure your environment. Chapter 2 Topics In this chapter, the following topics and concepts are presented: What the organization of the operating system components and architecture are What the basic Windows operating system architecture is What access controls and authentication are What security tokens, rights, and permissions are What users, groups, and Active Directory are What Windows attack surfaces and mitigation are What fundamentals of Microsoft Windows security monitoring...

...window of vulnerability ITT tech | Window of Vulnerability | Review of unauthorized access to SMB server. | | Cory Reiss | 4/1/2014 | This is the Window of Vulnerability For a patch to a newly discovered exploit residing in manufacturer software. | The security breach was detected by the server software manufacturer and a patch is currently being worked on. This vulnerability affects the SMB server giving access to an unauthorized user. The estimated time for the patch to be completed is three days with 7 additional days required for testing and executing the patch. There has been no documented timeline on when the security exploit was established, discovered, or executed. From discovery of the breach yesterday to final completion of fix there is a window of vulnerability consisting of 11 days. From the information presented the exploit only affects the SMB server. If the unauthorized user is able to run an interactive shell this should not be taken likely. Recommended procedure should be to block access on ports defined or suspend the server if possible. Access to SMB can put all of your files at risk and an aftermarket firewall blocking all IP ranges not specified in the workgroup should lower and impede the effectiveness of the exploit. Scans should be run to assess the possibility of injected code or malware. Someone skilled in security forensics should be deployed to assess the files affected or viewed. This can also give you a direction to search for...

...Window Of Vulnerability (WoV) Window of Vulnerability (WoV) is calculated from the time the attack started to when the attack is found removed or fixed. In this case the attack was found but just referred to as the previous day and the detection was found by the server software. We will say that the attack was on a Monday morning. The software company will be releasing a patch for the attack in three days. We should receive the patch on Thursday then. When we get the patch we will need to install and test the patch, this will take generally according to the size of the computer and the # of end users any part of one week to complete the testing before putting it into production. Once the testing is done on all workgroups & end users devices the patch will need to be installed which is considered into production. The update will be company-wide to all machines that access the network. We will need to send out notification office wide via memo and/or email message to all employees. We should request that all end user’s leave the PC’s or devices on so that we can remotely install the updates or for all of the end users that contain windows 7 which most companies do have the upgrade from XP since it will soon be unsupported, you can use Microsoft Deployment Toolkit (MDT) to automate the update to reduce the Desktop support time & cost to do each and every machine.
