We are pleased to announce that Tenable Network Security has been awarded Common Criteria certification, again meeting the rigorous security requirements defined by the Common Criteria for Information Technology Security Evaluation.

Keeping Your Firewalls in Check

Ensuring that your network infrastructure, in particular your routers and firewalls, is secure and maintains its integrity is critical to successfully defending your network. If an attacker were to gain control of these types of systems, they could potentially impact the security of your network as a whole. For example, an attacker with access to your firewall could read the firewall rules and use the information to selectively attack open services and create backdoors that would slip through your firewall.

The Benefits of Proper SSL Configuration

Protecting your vulnerability data from unauthorized users, whether the threat comes from external attackers or malicious insiders, is an important part of a vulnerability management program. Nessus allows users to configure SSL to provide both privacy and authentication. SSL can be configured locally or integrated into your own PKI infrastructure, allowing Nessus to be compliant with in-house security policies and standards.

The new Windows 8 interface provides a very different user experience than past Microsoft operating systems. Nessus can enumerate and detect vulnerabilities on Windows 8 hosts.

Recently, Microsoft made several announcements surrounding new technology, including a new operating system (Windows 8) and a new tablet platform called "Surface." Windows 8 will present a new interface and several new changes under the hood. They're an offshoot of the new platform called Windows RT, a small, fast, and lightweight version designed to run on ARM-based tablets. In fact, this is much of the reason behind the concept of Windows 8 -- it’s meant to run on tablets and touch screens. Windows Phone 8 is the new OS for Windows-based phones, such as those from Nokia.

Not too long ago, CVE-2012-4681 (US-CERT Alert TA12-240A and Vulnerability Note VU #636312) was issued for a flaw discovered in Oracle Java (JDK and JRE 7 U6 and before), as well as version 6 U34 and before.

This is a client-side vulnerability, which requires a user to initiate activity to be exploited. I will avoid dissecting the flaw in detail, as this information is widely available on the Web (a particularly good write-up is here).

Keep in mind that Java is platform independent, and so is this exploit. The example here uses Internet Explorer on Windows 7 (with Java SE 7u3). However, Linux and OS X users shouldn’t feel excluded on this one!

With Tenable's Unified Security Monitoring (USM) platform, comprised of SecurityCenter (SC), the Passive Vulnerability Scanner (PVS), and the Log Correlation Engine (LCE), we can track this exploit from start to finish.
