Disclosing PC Vulnerability Santa Rosa CA

IT security revolves around the concept of vulnerability: the attacker wants to find and exploit it, while your aim is to ensure that it doesn't exist. Unfortunately, while the former is child's play, the latter is harder than it may seem.

IT security revolves around the concept of vulnerability: the attacker wants to find and exploit it, while your aim is to ensure that it doesn't exist. Unfortunately, while the former is child's play, the latter is harder than it may seem. As Lawson explains: "All software has faults; this is an immutable fact about code written by humans. It's critically important computer systems are kept up to date, as the updates fix the bugs that could lead to a compromise by a hacker. Microsoft has made this incredibly easy with the Automatic Updates tool. Ensure this tool is running to download updates automatically. Corporate environments should test all updates prior to deployment to ensure the update doesn't affect business functions."

The Microsoft Baseline Security Analyzer (www.microsoft.com/technet/security/tools/mbsahome.mspx) is another easy-to-use tool designed for the IT professional that can help small and medium-sized businesses to determine their security state in accordance with Microsoft security recommendations.

But what about when you move away from your computer and the vulnerabilities of the OS, and look towards your website instead? Fogerty recommends two distinct approaches: web-server and web-application testing. "With web-server testing you're testing the underlying web server (IIS, Apache) to make sure it's patched and in a hardened configuration. Run free tools like Nikto or Nessus to check for vulnerabilities," he says. Both are available to members of Hackerwhacker as mentioned earlier.

"With web-app testing, you are looking at the application that sits on the web server. This is usually a custom application and could be susceptible to SQL Injection, Cross Site Scripting (XSS) and Cross Site Request Forgery (CSRF) vulnerabilities if the developers have not used 'defensive programming'; that is, not validating input from the client before acting on it," Fogerty adds. "There are plenty of free web-app testing proxy tools that act as a middle-man between the client and server. You can then insert 'malicious' data into the HTTP stream to see if the web app fails to deal with it." Try Achilles (www.mavensecurity.com/achilles), Burp (www.portswigger.net/proxy) or Paros (www.parosproxy.org/download.shtml) for starters.

It goes without saying that attackers follow security vulnerabilities, as these are a requirement for their success. Over the past several years, these vulnerabilities have increasingly moved up the application stack and away from the core operating system. Threats have moved (and will continue to move) into other areas, such as the Web application layer, where the majority of all new security vulnerabilities reside today. These threats target more available technologies, including email, IM, and the Web, leveraging social engineering and other convincing trickery in order to infect their victims.
