2023 saw two concerning attacks on public water systems, highlighting the fragility and risk to utility systems. In Pennsylvania, malicious hackers breached the Municipal Water Authority of Aliquippa system the night after Thanksgiving. The criminals were making a political statement: the technology used to manage water pressure was developed by Israel, and the criminals used this opportunity to...

US federal agencies have teamed up to release a cybersecurity best practice guidance for the water and wastewater sector (WWS). The Cybersecurity and Infrastructure Security Agency (CISA), United States Environmental Protection Agency (EPA), and Federal Bureau of Investigation (FBI) have published the guide in an attempt to promote cybersecurity resilience and improve incident response in the WWS...

One of the most common factors that can lead to cybersecurity incidents is a security misconfiguration in software or application settings. The default settings that come with the implementation of these tools and solutions are often not configured securely, and many organizations do not invest the time and resources into ensuring that they are. Several regulatory organizations have established...

Imagine you’re on the tail end of installing a 100-line script. It’s five o’clock, and you’re ready to head out early for once. You run the startup script on a new server, and then – the fated error message. Something isn’t working, and only after painstakingly reviewing 67 lines of code do you realize you had the IP address wrong. This could have been prevented. File Integrity Monitoring (FIM)...

To most people, the process of logging into a Microsoft Windows machine is a simple process of entering a username and a password. However, for a cybersecurity professional, the process is a carefully orchestrated mechanism. Unfortunately, throughout the history of the various Windows operating system versions, criminals have also sought ways to disrupt this process in order to breach a network...

At Tripwire's recent Energy and NERC Compliance Working Group, we had the opportunity to speak with the Manager of Gas Measurement, Controls, & Cybersecurity at a large energy company. More specifically, we focused on SCADA and field assets of gas Operational Technology. The experience at the management level of such an organization provided a wealth of knowledge for the attendees. SCADA...

The shifting sands of IT make the adage "you never know it all" ever more true as time goes by. I recall days when it felt like you could click through every major directory of Yahoo and know a little something about everything. I was a young man with a voracious reading appetite and an active imagination – both of which were thoroughly outpaced by the growth of the internet and my own developing...

Back in 1992, when I was more concerned about my acne breakouts and being selected for the Junior cricket team, a freshman at Purdue University was studying the impact of the 1988 Morris Worm event and how it brought about unwarranted changes on Unix systems as it propagated across the network, resulting in the first Denial of Service (DoS) attack. He quickly realised that it was hard to know when...

In the digital world, where countless users communicate, share data, and engage in diverse activities, determining the origin and actions behind these interactions can be quite challenging. This is where non-repudiation steps in. Coupling other security factors, such as delivery proof, identity verification, and a digital signature, creates non-repudiation. This guarantees that the parties...

What is an Attack Surface? An attack surface is the total number of channels, pathways, or areas that threat actors can utilize to gain unauthorized access to networks. The result is that they can obtain private information or carry out a cyber-attack. An attack surface comprises the organizational assets a threat actor can exploit to gain unauthorized access. Attack surfaces include systems that...

Frankly stated, operational resilience is your ability to climb the mountain, no matter the weather. Businesses now need more than a good security structure to weather the storms of AI-driven threats, APTs, cloud-based risks, and hyper-distributed environments. And more importantly, operational resilience in 2024 requires a paradigm shift. Attackers aren’t out there doing the bare minimum . As the...

Server Message Block (SMB) protocol is a communication protocol that allows users to communicate with remote servers and computers, which they can open, share, edit files, and even share and utilize resources. With the expansion of telecommunications, this protocol has been a prime target for threat actors to gain unauthorized access to sensitive data and devices. In 2017, we introduced 5 general...

In the vast and ever-evolving universe of information technology, there's one constant: change (that and cliches about constants!). Servers, systems, and software – they all get updated and modified. But, have you ever stopped to consider how even tiny differences between these digital entities can sometimes lead to unexpected challenges? In the world of Tripwire, we like to call this phenomenon...

What Is Secure Access Control? Secure access control, part of the broader field of user management , is a key concept in the realm of information security, particularly in the business environment. It refers to the process of selectively restricting and allowing access to a place or resource. In the context of information technology, it is a vital element of data protection, dictating who or what...

More decision-makers are investing in grid modernization efforts, knowing that doing so is necessary for keeping pace with modern demands. For example, smart grid fault-detection sensors could warn utility company providers of problems in real time, preventing costly and inconvenient outages. Technologies like the Internet of Things (IoT) can also improve stability. An IoT grid-monitoring approach...

Configuration management is vitally important as part of a sound cybersecurity strategy. We have previously published how patching alone is not enough, as that does not alter a system’s customized configuration. Misconfigurations can be as damaging to security as a deliberate attack on a system. As the manufacturer of Tripwire Enterprise (TE) , we thought that it would be prudent to help our...

There are countless tools and technologies available to help an organization stay on top of its IT assets, and a configuration management database (CMDB) is an extremely useful one. The database keeps track of relevant information regarding various hardware and software components and the relationships between them. It allows IT teams to have an organized view of configuration items (CIs) that can...

Attacks against industrial control systems (ICS) are on the rise. Cyberattacks are more prevalent, creative and faster than ever. So, understanding attackers’ tactics is crucial. The IBM Security X-Force Threat Intelligence Index 2023 highlights that backdoor deployments enabling remote access to ICS systems were the most common type of attacker action in 2022. The positive news is that 67% of...

Compliance and security often go hand in hand as ideas that attempt to protect against cyber threats. While both compliance and security are designed to lower risk, they are not mutually inclusive—that is, not everything that is required for compliance will necessarily help with security, and not everything that bolsters security will necessarily put you in compliance. Both are vital to...

A joint cybersecurity advisory from the United States's National Security Agency (NSA) and Cybersecurity and Infrastructure Security Agency (CISA) has shone a light on the top ten most common cybersecurity misconfigurations found in large private and public organisations. The report aims to detail the weaknesses found in many large organisations, and the need for software makers to properly...
