Russian cyber actors from the GRU Main Center for Special Technologies (GTsST), field post number 74455, have been exploiting a vulnerability in Exim Mail Transfer Agent (MTA) software since at least August 2019, warns a new National Security Agency (NSA) cybersecurity advisory.
To apply true holistic security best practices and reduce significant risks to the mainframe, security teams must embrace an integrated mainframe security strategy.
ISACA has updated its performance CSX Cybersecurity Practitioner (CSX-P) certification with expanded job tasks that span and test across five key security functions – Identify, Protect, Detect, Respond, and Recover.
Probationary employees—generally those with less than 1 or 2 years of federal service—can be especially vulnerable to reprisal because they have fewer protections from adverse personnel actions, including termination, the Government Accountability Office found.
To bolster the resilience of the Global Positioning System (GPS) and the wide scope of technologies and services that rely on precision timing, the U.S. Department of Commerce’s National Institute of Standards and Technology (NIST) is requesting information from the public about the broad use of positioning, navigation and timing (PNT) services, as well as the cybersecurity risk management approaches used to protect them.
Researchers at NIST have developed a mathematical formula that, computer simulations suggest, could help 5G and other wireless networks select and share communications frequencies about 5,000 times more efficiently than trial-and-error methods.
All too often, business leaders, city planners, fire departments, and law enforcement focus on their mandates to the exclusion of others. Unfortunately, this approach can lead to a breakdown in communication and missed opportunities. In the worst cases, it can create a lapse in security that could make their city and its citizens vulnerable to criminal activity and terrorist attacks. But, by eliminating these silos and fostering strong communication, stakeholders can share information that allows them to quickly address evolving situations.
