Security Information Siemens provides products and solutions with industrial security functions that support the secure operation of plants, systems, machines and networks. In order to protect plants, systems, machines and networks against cyber threats, it is necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial security concept. Siemens’ products and solutions only form one element of such a concept. Customer is responsible to prevent unauthorized access to its plants, systems, machines and networks. Systems, machines and components should only be connected to the enterprise network or the internet if and to the extent necessary and with appropriate security measures (e.g. use of firewalls and network segmentation) in place. Additionally, Siemens’ guidance on appropriate security measures should be taken into account. For more information about industrial security, please visit http://www.siemens.com/industrialsecurity. Siemens’ products and solutions undergo continuous development to make them more secure. Siemens strongly recommends to apply product updates as soon as available and to always use the latest product versions.

  • Cyber Security Trends: Aiming Ahead of the Target to Increase Security in 2017
    Cyber Security Trends: Aiming Ahead of the Target to Increase Security in 2017 A SANS Whitepaper Written by John Pescatore March 2017 Sponsored by Qualys ©2017 SANS™ Institute Introduction In security, change always equates to risk. Because change is constant, being aware of the key changes that will increase risk is a critical part of being proactive in cyber security. A simple equation for risk is the following: RISK THREAT VULNERABILITY ACTION Threats are Vulnerabilities Action consists of two malicious tactics are weaknesses components: and techniques that enable • Attacks that malicious actors (external that would cause those threats to or internal) take to launch threats damage to a succeed. business. • Prevention or mitigation efforts by security teams to reduce the attack aperture or increase speed of detection In reality, security teams control only half of the “Action” parameter. We can’t determine when threats will be developed or launched, and vulnerabilities are driven by weaknesses in people and technology. People change slowly, but technology changes rapidly, and business adoption of new technologies invariably brings new vulnerabilities that enable new threats. Understanding and anticipating business demand for emerging technologies is a key element in successful security programs. With each new wave of technology, threats tend to come in three forms: denial-of- service (DoS) attacks, cyber crime and attacks by nation-states. DoS Attacks When weaknesses in new technologies are exposed (generally by experimenters, academics and hacktivists), DoS attacks are the easiest to launch. They crash systems or cause data storms that bring networks to a halt. Cyber Crime Cyber criminals and the ecosystem that supports them refine attacks to focus on approaches that can lead to revenue, most commonly by stealing information that can be resold or support account fraud.

  • Identifying Software and Protocol Vulnerabilities in WPA2 Implementations Through Fuzzing
    POLITECNICO DI TORINO Master Degree in Computer Engineering Master Thesis Identifying Software and Protocol Vulnerabilities in WPA2 Implementations through Fuzzing Supervisors Prof. Antonio Lioy Dr. Jan Tobias M¨uehlberg Dr. Mathy Vanhoef Candidate Graziano Marallo Academic Year 2018-2019 Dedicated to my parents Summary Nowadays many activities of our daily lives are essentially based on the Internet. Information and services are available at every moment and they are just a click away. Wireless connections, in fact, have made these kinds of activities faster and easier. Nevertheless, security remains a problem to be addressed. If it is compro- mised, you can face severe consequences. When connecting to a protected Wi-Fi network a handshake is executed that provides both mutual authentication and ses- sion key negotiation. A recent discovery proves that this handshake is vulnerable to key reinstallation attacks. In response, vendors patched their implementations to prevent key reinstallations (KRACKs). However, these patches are non-trivial, and hard to get correct. Therefore it is essential that someone audits these patches to assure that key reinstallation attacks are indeed prevented. More precisely, the state machine behind the handshake can be fairly complex. On top of that, some implementations contain extra code to deal with Access Points that do not properly follow the 802.11 standard. This further complicates an implementation of the handshake. All combined, this makes it difficult to reason about the correctness of a patch. This means some patches may be flawed in practice. There are several possible techniques that can be used to accomplish this kind of analysis such as: formal verification, fuzzing, code audits, etc.

The spreader was apparently built by someone with "more advanced skills" than those that had created the original Mirai malware. This, Kaspersky Lab says, has "worrying implications for the future use and targets of Mirai-based attacks." It is richer and more robust than the original Mirai codebase, even though many of its components are "several years old." Its spreading capabilities are limited, as it can only deliver from an infected Windows host to a vulnerable Linux-powered IoT device. Even that -- if it can brute-force a remote telnet. It was also said that the author is likely Chinese- speaking, more experienced, but probably new to Mirai. "The appearance of a Mirai crossover between the Linux platform and the Windows platform is a real concern, as is the arrival on the scene of more experienced developers.

  • Is Cloudbleed Inevitable After Heartbleed? by Taiye Lambo and Jordan Flynn September 2014
    Is Cloudbleed Inevitable After Heartbleed? By Taiye Lambo and Jordan Flynn September 2014 In the technology world, vulnerabilities and bugs are commonplace. Whether an avid hobbyist or a professional working for an organization in a technical capacity, those familiar with the technology and information security space understand that there is no avoiding the inevitable discovery of vulnerabilities and bugs that must ultimately be addressed. While some of these fixes require nothing more than a simple patch job, others necessitate significant changes in policy and process within the workplace and the cautious or discontinued use of applications on mobile devices and Internet based services. With the rise in cybersecurity attacks and the continued growth of individuals storing their sensitive information online, vulnerabilities in cyberspace represent one of the most significant concerns not just for hobbyists and professionals, but also for society as a whole. The discovery of the Heartbleed bug in April 2014 made the issue of vulnerabilities and bugs in cyberspace more evident. Fundamentally, the vulnerability allows for anyone on the Internet to read and view the personal and sensitive information of others through system memory, information meant to be protected by the SSL/TLS encryption that is used to secure the vast majority of the Internet. Compounding this issue is that Heartbleed also provides the proverbial “key to the kingdom” by making the confidential keys used to properly identify service providers, and encrypt the names and passwords of users as well as actual content itself available to the criminal, allowing them to easily spy on communications and impersonate both users and services therefore stealing sensitive data directly from them.

  • The Most Dangerous Cyber Nightmares in Recent Years Halloween Is the Time of Year for Dressing Up, Watching Scary Movies, and Telling Hair-Raising Tales
    The most dangerous cyber nightmares in recent years Halloween is the time of year for dressing up, watching scary movies, and telling hair-raising tales. Events in recent years have kept companies on high alert. Every day we are seeing an increase in cyberattacks carried out by organized hacker organizations. In a matter of seconds, these threats can destabilize large corporations, stealing large quantities of money and personal data, as well shake the very foundations of entire world powers. Have a look at some of the most terrifying attacks of recent years. 2010 2011 2012 Operation Aurora RSA SecurID Stratfor A series of cyberattacks carried out RSA suffered a security breach as a Publication and dissemination of worldwide, targeting 34 companies, result of a cyberattack that sought internal emails exchanged between including Google.
