Ditch the Spreadsheet and Step Up Your Vulnerability Management Game

Moving from Nessus Pro to Tenable.sc or Tenable.io can easily help you mature your vulnerability management program. Here's what you need to know.

Does your vulnerability management workflow involve a spreadsheet at any point? If so, you’re doing it wrong. Well, maybe not wrong per se, but definitely inefficiently.

In my career, I’ve been both the recipient and the creator of some monster-sized vulnerability spreadsheets that triggered “whack-a-mole” remediation exercises. It can be daunting to determine not only what to fix, but in what order.

New in Nessus: Elliptic Curve Cryptography with SSH

Cryptography is like finding and patching system vulnerabilities. Both are a race. In the former, the race is between mathematicians finding efficient, hard-to-reverse computations and opposing mathematicians solving hard numerical problems to defeat them. In the latter, the race is between IT and malicious actors who may find the vulnerabilities first to exploit them. The race in encryption is fueled by the exponential increase in computing power outlined by Moore’s law, constantly driving the algorithms we use toward obsolescence.

This post was updated on Jan. 12, 2018 to include additional technical details and supplemental links.  

The recently disclosed Meltdown and Spectre vulnerabilities started off 2018 with a somber note, as the attacks affect everything from desktops, laptops and mobile devices to cloud providers’ infrastructure.

Detecting macOS High Sierra root account without authentication

Yesterday, Tenable™ released two plugins to detect macOS High Sierra installs which allow a local user to login as root without a password after several login attempts. Both plugins require authentication, however, there was one scenario where a user could log in over VNC protocol with the root account and no password if screen sharing was enabled. Today, we are releasing a plugin to remotely detect the vulnerability without authentication.

Auditing Databases with Nessus

As a companion to another post on hardening network devices and creating baseline configurations, I wanted to look at another area where standardizing configurations can pay off in a big way. While there is plenty of fertile ground out there, I decided to focus on some specific aspects of databases. As I started reviewing recent research, I noticed a couple of interesting things from the world of finance that likely aren’t radically different from most environments.

Rooting a Printer: From Security Bulletin to Remote Code Execution

Printers. They are everywhere. In big businesses. In small businesses. In our homes. In our schools. Wherever you go, there they are. But where are they in your threat model? When was the last time you updated the firmware? Do you know if there are public exploits for your printer?

For example, in early April, Hewlett Packard released a security bulletin titled, HP PageWide Printers, HP OfficeJet Pro Printers, Arbitrary Code Execution. The bulletin states:
