Five Steps to Building a Successful Vulnerability Management Program
CDM: Making US Federal Agencies More AWARE of Cyber Exposure
At a recent Tenable sponsored MeriTalk event, Kevin Cox, program manager for Continuous Diagnostics and Mitigation (CDM), provided a preview of coming attractions regarding the CDM federal dashboard. As of this writing, the CDM dashboard is in its initial production stage, with agency exchanges being set up to aggregate the data to be fed into the dashboard. At least five agencies are reportedly on track to have data uploaded to the CDM dashboard during the first quarter of 2018. Agency-Wide Ad ...
Intel AMT Back in the News
The release of new research from F-Secure spells more trouble for Intel’s Active Management Technology (AMT). AMT is used for remote access monitoring and maintenance in corporate environments. Previously, in 2017, researchers discovered a critical vulnerability with AMT that made headlines. The previous vulnerability was a wide-reaching privilege escalation vulnerability (INTEL-SA-00075, CVE-2017-5689). Now, AMT is in the news again this week, as another serious security issue has been di ...
Tracking Scan Authentication Failures
IT systems change all the time. New applications are added, configurations are changed, permissions get revised – the list goes on and on. In some cases, the changes end up restricting access to the system. For example, user accounts are removed, access is revoked, account credentials change or expire, leading to unexpected authentication failures and lockouts. And when the credentials fail, applications that depend on them fail, too. When the application that ends up failing is a vulnerab ...
The First Major Security Logos of 2018: Spectre and Meltdown Vulnerabilities
A major flaw in the way modern CPUs access cache memory could allow one program to access data from another program. The latest security vulnerability affects a majority of systems, if not all, used today. The vulnerabilities are named Spectre and Meltdown and also have a dedicated website. According to the security advisory, Spectre breaks the isolation between different applications and allows an attacker to expose data once thought to be secure. Meltdown breaks the most fundamental isolation ...
Auditing Kubernetes for Secure Configurations
Over the last few years, container technology has gained traction in enterprise environments. And, as a result, use of containerized applications has exploded in the enterprise. Naturally, as its adoption increased, management platforms such as Kubernetes were developed to manage containerized applications. They’ve now become critical to any modern DevOps-focused infrastructure. Tenable recently released an audit to help customers secure this key piece of infrastructure in their environmen ...
Triton: What You Need to Know
What is Triton? Triton is a new malware framework targeting safety systems monitoring SCADA networks. It’s designed to run from within a compromised network, allowing the attacker to observe and control Triconex Safety Instrumented System (SIS) devices. The attackers copied a malicious file (trilog.exe) onto a management workstation, a Windows PC, and used that vantage point to attempt to write new firmware to the memory of SIS devices. Device firmware is designed to be updated remotely. A ...
Congress Achieves Real IT Modernization Progress
We’ve talked about the need for Congress to prioritize upgrading and modernizing government IT systems for a while now, so we were glad to see the Senate recently pass the 2017 National Defense Authorization Act (NDAA) with the Modernizing Government Technology (MGT) Act intact. The MGT Act (HR 2227), introduced by Rep. Will Hurd (R-TX), was signed into law last Tuesday. Federal IT modernization is a critical component of strong government cybersecurity, and the necessity for this bill is ...
New Study: Many Consumers Lack Understanding of Basic Cyber Hygiene
Data breaches have been a headache for many years and for a long time there seemed to be a general apathy about them. Our sense was that things may have changed in the wake of the most severe breach ever – the theft of 145 million social security numbers and other sensitive data from Equifax – which leaves most Americans with the burden of having to monitor for identity theft for the rest of their lives. Against this backdrop, we decided to find out how aware Americans are of cyberse ...
