As most IT Pros are aware, as of April 8th, 2014, Microsoft will stop releasing security patches for Windows XP. Unfortunately, most folks will not be able to migrate all Windows XP machines by that deadline. How will you limit the security risks posed by these now vulnerable assets? Join us for this webinar outlining practical strategies to help you cover your assets. In this session we'll cover: The primary attack vectors you need to consider Immediate actions you can take to limit the exposure of your XP assets Warning signs to watch out for that could signal an attack How to closely monitor your vulnerable assets with AlienVault USM

Cover your Assets: How to Limit the Risk of Attack on your XP Assets

- 3. THE CHALLENGE Windows XP is end of support and subsequently creating risk for your organization: What does “end of support” mean? How do you find out of date assets? Are your out of date assets vulnerable? Are your out of date assets being attacked? What else can you do to manage the risk created by out of date assets? Event correlation rules and reports

- 6. ATTACK VECTORS TO CONSIDER Network Exploits – this is our traditional network worm, which is exploiting a service running on our XP machine. A classic example of this is the conficker worm that targeted a vulnerability in the server service in Windows XP. Browser-based attacks – this is our most common attack, where a user is targeted as they are browsing the web (or are sent a malicious link in an email) and an exploit targeting the browser or an enabled browser plugin is used to compromise the machine. Malicious Email attachments – another favorite, a malicious attachment is sent with an email and an exploit targeting the program configured to read the attachment is used (our most common target here is the PDF viewer)
- 7. IMMEDIATE ACTIONS TO LIMIT YOUR RISK Limit Inbound Network Access – place the XP machines on a dedicated network segment and limit access by other machines in your environment. (This mitigates Network Exploits) Use a Non-Administrative Account – the majority of exploits targeting desktop software are mitigated when the user account is a standard user. (This mitigates Browser-based attacks and malicious email attachments) Use a browser with a long-term support plan - Google Chrome is extending their XP support until April 2015. If you do choose to browse, turn off your plugins (This mitigates Browser-based attacks) Read your email in your browser – leverage your email server’s web front-end and be particularly conservative about the attachments you download and open. (This mitigates Malicious email attachments) Monitor your systems - The most important thing is catching an incident before it turns into a problem.

- Limit Inbound Network Access – place the XP machines on a dedicated network segment and limit access by other machines in your environment. Keeping these machines segmented will minimize the chances for these machines to be targeted and exploited. Limiting network access substantially reduces your chance of being targeted and compromised by network exploits. The assets you most need to be concerned about are running your business systems. The point of sale terminals at Target were running Windows XP embedded - cutting them off from the rest of the network would have done a lot! (This mitigates Network Exploits)Use a Non-Administrative Account – the majority of exploits targeting desktop software (web-browsers, java, adobe flash, adobe reader) are mitigated when the user account is a standard user. It is a disruptive task to try and migrate an existing user to a non-administrative account. Instead, try reducing the privileges of your existing user accounts. (This mitigates Browser-based attacks and malicious email attachments)Use a browser with a long-term support plan – if you can’t stop browsing the web from the Windows XP machine, at least use an up-to-date browser. Google Chrome is extending their support until April 2015. If you do choose to browse, please turn off your plugins This mitigates Browser-based attacksRead your email in your browser – using your up-to-date browser, (you are following recommendation 3 right?) leverage your email server’s web front-end and be particularly conservative about the attachments you download and open. (This mitigates Malicious email attachments)Monitor your systems – always check your work! The most important thing is catching an incident before it turns into a problem. Look out for command and control traffic, internal probing, increased network activity and other signs of an infection.
