How will we detect the next one? New measures include Layer 7 application session monitoring to discover zero-day threats and to detect covert communications over allowed overt channels. The dangers posed by attacks on cyber-physical systems extend to all varieties of network-enabled physical plantsthe advantages of network connectivity can be exploited by attackers if the underlying cyber-physical system is not adequately protected. SIGMA Generic Signatures: In this lab students will understand how to use and implement Sigma generic signature rules, a new community driven project, to convert generic signatures into various formats for operational use. IPv6: The Next Generation Internet Protocol, also known as IPv6, is often ignored and misunderstood. PLCs and RTUs that do not run modern operating systems lack the necessary attack surface to make them vulnerable. Computers can calculate trust on the fly, so rather than thinking in terms of "trust but verify" organizations should be implementing "verify then trust." This indicates significant resources and expertise were needed to design and release it. Therefore, these features are considered in the attack scenarios discussed throughout this chapter. One of the most famous examples of a cyberattack that was deployed for surveillance was the Solarwinds supply chain attack. Another approach might be to perform man-in-the-middle attacks intercepting invalid process values received from the PLCs and forward to the WinCC HMI bogus values for display making the plant operator unaware of what is actually occurring in the plant. And perhaps most of all, help is needed from the processors in all our computers to help block the vectors of attack used by Stuxnet. Hackers can also use personal information for impersonation or identity theft. [12] It was later used on HMA (His Majesty's Airship) No. How can we locate malicious software, such as Stuxnet, which was designed to go undetected? A cyber attack is an unauthorized attempt to access a computer system to either size, modify, or steal data.. Cybercriminals can use a variety of attack vectors to launch a cyberattack including malware, phishing, ransomware, and man-in-the-middle attacks.Each of these attacks are made possible by inherent risks and residual risks.. A cybercriminal may steal, alter, or destroy a The Su-30MKI is powered by two Al-31FP afterburning turbofans. The attack proceeded through several stages in Stuxnet 0.5, with a similar process being used in later versions of Stuxnet: After recording a snapshot of valve behavior, Stuxnet attacked the valves and replayed the snapshots. Theft of servicesAn adversary may want to make use of the plant without damaging it. In six days filled with case studies, winning techniques, instructor-led demos, and plenty of hands-on labs (including a NetWars-based Defend-the-Flag challenge), students will learn how to design, build, and harden networks, infrastructure, and applications that can truly be called 'defensible. Stuxnet was discovered in 2010 and has been closely examined since then (Falliere et al., 2011). This includes convergent and convergent-divergent nozzles that may be fixed or geometrically variable. Cyber Command is a military subcommand under US Strategic Command and is responsible for protecting military cyberinfrastructure. If such a craft is flown in a way where it enters a vortex ring state, one of the rotors will always enter slightly before the other, causing the aircraft to perform a drastic and unplanned roll. Before coming to class, carefully read and follow these instructions exactly. What are the implications of malicious software that can affect real-world equipment? The Sukhoi Su-30MKI, produced by India under licence at Hindustan Aeronautics Limited, is in active service with the Indian Air Force. One DLL was used to insert malicious code into the PLC. Fernandes, Pedro R.M. Thrust-vectoring flight control (TVFC) is obtained through deflection of the aircraft jets in some or all of the pitch, yaw and roll directions. This is not normal modus operandi for state-sponsored cyber operations, not only because it means the attack will almost certainly be discovered, but also because of potential blowback. Specifically, the attack code looked for CascadeModule identifiers in the range A21 to A28, which correspond to cascade modules in the Natanz facility. Figure 6.3. It is able to inject code into the PLCs, and at that point alter the operations of the PLC as well as hide itself by reporting false information back to the HMI. In Spain, a bill draft authorizes the police to install malware on computers without the owners knowledge [113]. [16] TVFC includes control of STOVL aircraft during the hover and during the transition between hover and forward speeds below 50 knots where aerodynamic surfaces are ineffective. Because this product was being used by the US Government, the cybercriminals were able to gain access to its networks and intercept private internal correspondences. In this section we introduce the fundamentals of security architectures and the journey towards Zero Trust. It is unclear whether Iran, which was attacked with Stuxnet, has the right to strike back under the Geneva Conventionafter all, cyber-war is a form of war if certain conditions are met [103]. What security assumptions are we making that can be invalidated? Stuxnet is a worm that spreads by infecting Windows computers. [16], When TVFC is implemented to complement CAFC, agility and safety of the aircraft are maximized. Password requirements: 6 to 30 characters long; ASCII characters only (characters found on a standard US keyboard); must contain at least 4 different symbols; The mysteriousness surrounding this saga raises suspicions pointing toward nation-state threats. VMware will send you a time-limited serial number if you register for the trial at their website. More on this in just a bit. The United States focuses on security plans in response to cyber warfare, acting in defense rather than attacking. Another attack was alluded in 2008, when a senior analyst for the CIA mentioned that there was an evidence of computer intrusions into some European power utilities, followed by extortion demands [13]. The strengths and weaknesses of one solution complement another solution through strategic placement, implementation, and continuous fine-tuning. Too much reliance on built-in capabilities like application control, antivirus, intrusion prevention, data loss prevention, or other automatic evil-finding deep packet inspection engines leads to a highly preventative-focused implementation, with huge gaps in both prevention and detection. Students will learn how to assess, re-configure and validate existing technologies to significantly improve their organizations' prevention, detection and response capabilities, augment visibility, reduce attack surface, and even anticipate attacks in innovative ways. Examples are the fast patrol boat Dvora Mk-III, the Hamina class missile boat and the US Navy's Littoral combat ships.[26]. The truth is that we may not, and the reason is simpleour barrier-based methodologies do not work against cyber-attacks that are this well researched and funded. A PCB engine, the Bristol Siddeley BS100, was cancelled in 1965. The problem is that critical and sensitive data exist all over. [16], To implement TVFC a variety of nozzles both mechanical and fluidic may be applied. [15] Tests show that air forced into a jet engine exhaust stream can deflect thrust up to 15 degrees. Some other projectiles that use thrust-vectoring: Most currently operational vectored thrust aircraft use turbofans with rotating nozzles or vanes to deflect the exhaust stream. It includes the capabilities to remove itself from incompatible systems, lay dormant, reinfect cleaned systems, and communicate peer to peer in order to self-update within infected networks. The other DLL was used to fingerprint the target system and build a PLC data block that could be used to attack the PLC. Furthermore, he asserts that the use of this protection system in Gauss has protected it from analysis by Kaspersky.28. This advanced worm had the capability to bridge the air-gap. Network administrators charged with the security of isolated systems face an interesting dilemma. (a) Exploiting zero-day flaws, Stuxnet is able to compromise computers through an infected USB drive. There are several operational and technical questions that must be answered as well. The reset caused safety systems to incorrectly interpret the lack of data as a drop in water reservoirs that cooled the plant's radioactive nuclear fuel rods resulting in the shutdown of the system [9]. Waiting until the night before the class starts to begin your download has a high probability of failure. The challenge for the management team designated to lead such a project would be to assign those with the better skill-sets to the more critical components of the project. There will be a heavy focus on leveraging current infrastructure and investment. However, not all meters may be reliable, either because the meter failed or due to tampering. There are many policy questionssome associated with cyber warfare, in generalnow taking on increased importance.69 How do we attribute such an attack? Nailah Mims, in Computer and Information Security Handbook (Third Edition), 2017. However, in doing so, they run the risk of spreading an infection (i.e., by memory stick or through a local area networkboth of which Stuxnet could propagate through). Your organization needs to have a set of policies and procedures to manage your information security in accordance with risk management principles and have countermeasures to protect financial, legal, regulatory, and reputational concerns. If you do not carefully read and follow these instructions, you will likely leave the class unsatisfied because you will not be able to participate in hands-on exercises that are essential to this course. Copyright 2022 Elsevier B.V. or its licensors or contributors. Covers topics such as reconnaissance, OS fingerprinting, remote network mapping, web application, software and network vulnerabilities, attack surface analysis, fuzz testing, exploitation of vulnerabilities, credential gathering, and privilege escalation. Other high-profile attacks have been quite common. Following a bumpy launch week that saw frequent server trouble and bloated player queues, Blizzard has announced that over 25 million Overwatch 2 players have logged on in its first 10 days. Stopping the next Stuxnet would take equivalent resources expended on the attack itself. A design for a jet incorporating thrust vectoring was submitted in 1949 to the British Air Ministry by Percy Walwyn; Walwyn's drawings are preserved at the National Aerospace Library at Farnborough. This gives cybercriminals the ability to sell their personal details on the dark web, demand ransom, or harass your customers. In this new environment, we have found that a second monitor and/or a tablet device can be useful by keeping the class materials visible while the instructor is presenting or while you are working on lab exercises. The EternalBlue patch was available for almost two months prior to the WannaCry attack, but it seems that few organizations had installed the patch. This lab shows how to use a SIEM system to find an attacker more than 10 different ways. Scale third-party vendor risk and prevent costly data leaks. A new bill currently being worked out on the United States aims to curb foreign threats [112]. Efforts have been made in numerous languages to translate the OWASP Top 10 - 2017. Diogo A.B. Uses infected PLCs to watch for specific behaviors by monitoring PROFIBUS. And again, by engineering defenses for modern attacks, both prevention and detection capabilities gain significantly. Three stages of the Stuxnet attack scenario: infection ((a) dash-dotted line), data recording ((a) dotted line), and sabotage ((b) dash-dotted line). Since Iran has an unusually high percentage of reported infections of the worms in the world, there has been some speculation that the attack targeted the frequency converters used by Uranium enrichment centrifuges in Iran, thus targeting the Iranian nuclear program. The Pentagon is assembling 13 teams capable of offensive cyber-operations and governed by a response framework giving them clear hacking authority [109]. They choose Cymulate to manage, know, Js20-Hook . The most publicized attack of this kind occurred in 2003 when the Slammer worm affected the computerized safety monitoring system at the DavisBesse nuclear power plant in the United States. If the liquid is injected on only one side of the missile, it modifies that side of the exhaust plume, resulting in different thrust on that side and an asymmetric net force on the missile. Blowback can come from the worm itself by infecting machines in the sponsoring nation's critical infrastructure, or political blowback from launching this type of visible attack. Complicating this even more is that data are often controlled by a full application stack involving multiple services that may be hosted on-premises or in the cloud. ", " I believe that no matter what is the team size we have, we will always have a backlog of projects and tasks. Motivated individuals and teams from government, corporate, academic, and black-hat (hacker) communities are constantly scrutinizing systems for the latest vulnerabilities. The sophistication of this attack has lead many to believe that Stuxnet is the creation of a state-level sponsored attack. Know, Control, and Optimize Your Cybersecurity Posture . where x is the state, e is the error, z is the measurement, and H is determined by the line impedances and Kirchoffs laws. Specifically infecting uranium production equipment in nuclear-empowered nations is a clear sign of government peeking, but it was likely an illegal act of force [102]. Stuxnet is an instance of a large malware saga that includes Duqu, Flame, and Gauss [104]. Astonishingly after being used a certain number of times,a Gauss removes itself from the USB stick. The STS SRBs used gimbaled nozzles.[4]. The primary target was a system comprising Siemens SIMATIC WinCC and PCS7 software along with specific models of S7 PLCs utilizing the PROFIBUS protocol to communicate with two specific vendors of variable frequency drives (VFD). You need to allow plenty of time for the download to complete. Infects Windows systems using a variety of zero-day exploits and stolen certificates, and installing a Windows rootkit on compatible machines. Will cyber weapons such as Stuxnet proliferate? Cyber threats can come in both intentional and accidental ways: This is why understanding the difference between cybersecurity and information security, as well as how to perform a cybersecurity risk assessment is more important than ever. In this use, most of the load is usually supported by buoyancy and vectored thrust is used to control the motion of the aircraft. In addition, the attackers had a good level of intelligence about their target: they knew all the details of the control system configuration and its programs. Likewise, we've continually seen that organizations that suffer massive breaches and business disruption often focused their emphasis prior to the breach on perimeter protection and prevention mechanisms but lacked defensible security architecture. Sapphire used solid copper vanes for copper's high heat capacity and thermal conductivity, and Nexo used graphite for its high melting point, but unless actively cooled, jet vanes will undergo significant erosion. The defensible security mindset is "build it once, build it right." When found, it injects itself into an SQL database (WinCC) or project file (Step 7), and replaces a critical communication driver that will facilitate authorized and undetected access to target PLCs. Mo et al. Researchers at the University of Kent identified at least 57 negative impacts from cyber attacks ranging from threats to life, causing depression, regulatory fines, and disrupting daily activities. Each centrifuge has its own set of valves. The Saturn V and the Space Shuttle used gimbaled engines. Powered by NetWars, day six provides a full day of hands-on work applying the principles taught throughout the week. Cymulate helps us to prioritize them and focus on issues that carry the most risk for the business, this has increased our effectiveness, we arent wasting valuable resources. The use of multiple zero-day vulnerabilities to deploy a targeted attack indicates that blacklist point defenses, which compare traffic to definitions that indicate bad code are no longer sufficient, and whitelist defenses should be considered as a catchall defense against unknown exploits. Internet-connected water heaters, designed to save energy costs, could be harnessed for large-scale attacks that could cause huge amounts of physical damage. We learn from Stuxnet and change our perception and attitude toward industrial network security (see Table 7.3). It is the first rootkit targeting ICS. Such highly-complex cyberattacks are able to bypass firewalls and VPNs because they hide behind legitimate computer processes. Aurora used a zero-day vulnerability in Microsoft Internet Explorertaking advantage of a common application many use on a daily basis.67 This particular cyber attack is a good example of cyber espionagethe attackers sought to steal information from the target. Browse our listings to find jobs in Germany for expats, including jobs for English speakers or those in your native language. Cybercriminals can use a variety of attack vectors to launch a cyberattack including malware, phishing, ransomware, and man-in-the-middle attacks. Immediately apply the skills and techniques learned in SANS courses, ranges, and summits, Build a world-class cyber team with our workforce development programs, Increase your staffs cyber awareness, help them change their behaviors, and reduce your organizational risk, Enhance your skills with access to thousands of free resources, 150+ instructor-developed tools, and the latest cybersecurity news and analysis. Sets of centrifuges are organized into stages that form a cascade; additional auxiliary valves control access to the stages and the cascade. Hearing the stories from the trenches really made me feel like being able to apply. However, we should also note that some shortcoming of Stuxnet (such as its susceptibility to reverse-engineering) may be the result of the simple fact that this malware likely is the product of a large organization. The number of classes using eWorkbooks will grow quickly. Learning the TTPs (Tactics, Techniques, & Procedures) of previous threat actors can also help anticipate future cyber attacks. The industry is investing in cybersecurity to monitor domestic and foreign threats. Cyber Command is made up of Army Forces Cyber Command, Twenty-fourth Air Force, Fleet Cyber Command, and Marine Forces Cyber Command. What makes Stuxnet a watershed event in Cyber Warfare is the level of sophistication in the design of the worm. I've never seen any course lab environment executed so well. Effective security requires a balance between detection, prevention, and response capabilities, but such a balance demands that controls be implemented on the network, directly on endpoints, and within cloud environments. Because Stuxnet used four zero-day vulnerabilities, having an up to date and fully patched system could not provide defense against Stuxnet. Although little was known at first, Siemens effectively responded to the issue, quickly issuing a security advisory, as well as a tool for the detection and removal of Stuxnet. If the target contained Siemens SIMATIC software, methods existed to exploit default credentials in the SQL Server application allowing the malware to install itself in the WinCC database, or to copy itself into the STEP 7 project file used to program the S7 PLCs. It then would deploy up to seven different propagation methods to infect other targets. Section 1 will also introduce you to the principle of Time-Based Security and how to implement it in real world. It was designed to infect networks that were not connected to the Internet. FOX FILES combines in-depth news reporting from a variety of Fox News on-air talent. Labels could be used to identify particular functions in a given device and cascade. Paulo Shakarian, Andrew Ruef, in Introduction to Cyber-Warfare, 2013. You also must have 8 GB of RAM or higher for the VM to function properly in the class. Assure daily the operational effectiveness of your security stack that protect your IT environment, cloud initiatives and critical data against threat evolutions, " As Euronexts cybersecurity team, we know that cybersecurity is always a work in progress. Targeted attacks against power systems are not new. There are numerous questions that must now be addressed. It was able to install malicious drivers undetected by Windows through the use of two different legitimate digital certificates manufactured using stolen keys. Liu et al. Includes labs and exercises, and support. The responsibility for cybersecurity is divided between the Department of Homeland Security (Homeland Security), the Federal Bureau of Investigation (FBI) and the Department of Defense (DOD). *No credit card required. - Edmund L., Singapore Federal Agency. The detection capabilities are important but the logic behind them is also important to implement variable trust conditional access across an enterprise. Stuxnet is largely considered as a game changer in the industry, because it was the first targeted, weaponized cyber-attack against an industrial control system. This philosophy still has merit, the only difference being that now the hacker can be thought of as having a much greater knowledge of deployed ICSs, an understanding of the manufacturing processes, and how the ICS is used to control this environment, along with significantly more resources and motivation. What we do not know at this point is what the full extent of damage could be from the malicious code that is inserted within the PLC. Determine which solution is best for your organization. Your course media will now be delivered via download. Cymulate enables remote working by ensuring that VPN connections are secure and people continue to be productive with least privilege access. Cyber-physical systems are vulnerable to all sorts of traditional cyber attacks. It is also noteworthy that the majority of Gauss infections were discovered on Lebanese systems. SIEM Analysis and Tactical Detection: Logging and inspecting is difficult without the right data and the proper ability to view those data. They use sensitivity values to determine whether data values interact with each other; if one data values error is not sensitive to the presence of the other, that value can be pruned from the search tree. The PLA believes that seizing control of an opponent's information flow and establishing information dominance is fundamental to warfare success. (They pointed out that many homeowners plug their own relief valves under the mistaken impression that the valve is simply unused plumbing.) UpGuard is a leading vendor in the Gartner 2022 Market Guide for IT VRM Solutions. The latest Lifestyle | Daily Life news, tips, opinion and advice from The Sydney Morning Herald covering life and relationships, beauty, fashion, health & wellbeing Using compromised digital certificates, Stuxnet is able to bypass firewalls and it continues spreading itself through the local communication networks of the SCADA system. It was designed to stop compromising computers on July 4, 2009. All rights reserved. Securing Web Applications: In this lab, students will identify the prevention and detection capabilities that web application firewalls provide, and also learn where they can be evaded. Qin et al. Complete Guide to Extended Security Posture Management. Stuxnet is discussed in detail in Chapter 7, Hacking Industrial Control Systems., Alvaro A. Crdenas, Reihaneh Safavi-Naini, in Handbook on Securing Cyber-Physical Critical Infrastructure, 2012. For example, how do we best identify zero-day vulnerabilities (which by definition are unknown)? Egress Analysis: The focus is on understanding how attackers exfiltrate data with common techniques like DNS tunneling, and how to layer defenses to increase protection time while increasing the likelihood of detection. The next example discusses one of the largest known cyber-physical attacks, Stuxnet. Karl Ward | Lead Security Operations Analyst. Large-scale damageAccess to the plant can be effectively denied by damaging the plant, for example by controlling the plant in a way that causes it to damage itself. "Experimental Study of an Axisymmetric Dual Throat Fluidic Thrust Vectoring Nozzle for Supersonic Aircraft application" Flamme, Deere, Mason, Berrier, Johnson, "Variable Vectoring Nozzle For Jet Propulsion Engines" Johnson, U.S. Patent 3,260,049, "Reusable Solid Rocket MotorAccomplishments, Lessons, and a Culture of Success", "First test of air-to-air missile Astra Mk II likely on February 18", "Akash Surface-to-Air Missile (SAM) System-Airforce Technology", "Explained: From Pinaka to Astra, the new weapons DAC has approved 'for defence of borders', "STOCK IMAGE - A 1949 jet deflection vectored-thrust propulsion concept by www.DIOMEDIA.com", "Demonstration of Fluidic Throat Skewing for Thrust Vectoring in Structurally Fixed Nozzles", https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20070030933.pdf, "F-35B Lightning II Three-Bearing Swivel Nozzle - Code One Magazine", "Thrust Vector Aided Maneuvering of the YF-22 Advanced Tactical Fighter Prototype", "China's J-20 stealth fighters are getting an engine upgrade, source says", https://en.wikipedia.org/w/index.php?title=Thrust_vectoring&oldid=1118789327, Short description is different from Wikidata, Articles with unsourced statements from November 2014, Creative Commons Attribution-ShareAlike License 3.0, This page was last edited on 28 October 2022, at 22:28. No one should doubt the potential dangers posed by improperly operated or compromised cyber-physical systems. Learn more about the latest issues in cybersecurity. Monitor and optimize your security posture continuously. In many ways, those attacks were a classic example of a cyber attack with the aim to degrade a computer network. If the Siemens protocols for controllers and PLCs were open, security researchers could have pointed out that the hard-coded password used in their software was a glaring security problem. Layer 2 and 3 Benchmarks and Auditing Tools, Downloading the Cisco IOS Config via SNMP, Bogon Filtering, Blackholes, and Darknets, IPv6 Asset Inventory with Rumble Network Discovery, IPv6 Router Advertisement Attacks and Mitigation, Augmenting with Phishing Protection and Detection Mechanisms. Stuxnet would then spread through the network using peer-to-peer methods. This requires understanding how control system communications work, establishing that need to know and need to use in the form of well-defined security zones with equally defined perimeters, establishing policies and baselines around those zones, and then implementing cyber security controls and countermeasures to enforce those policies and minimize the risk of a successful cyber-attack. It is however believed that it had been released more than a year before that. Translation Efforts. Both the exhaust from this fan and the main engine's fan are deflected by thrust vectoring nozzles, to provide the appropriate combination of lift and propulsive thrust. The mechanical complexities of this design are quite troublesome, including twisting flexible internal components and driveshaft power transfer between engines. We will discuss and identify what solutions are available and how to apply them successfully to reduce attack surface and implement adaptive trust. For the DC motor control problem they used mean square tracking error as the performance metric P. They formulated the security metric as. The additional vulnerabilities introduced by the physical plant also create opportunities to protect the cyber-physical system. Goddard. Application such as the Step 7 application need to do a better job of detecting if they have been modified. Many crucial organizations are vulnerable to cyber attack. In other words, the attack originated from inside the targeted organization. Using the PLC rootkit, the malware modifies the PLC code to perform a disclosure attack and record the received data. Jorge Ruo | Head of Security Operations. It is understandable, then, why Stuxnet was so widely publicized, and why it is still talked about today. This scenario illustrates the complex behaviour of Stuxnet and the potential damage it could have. Assure daily the operational effectiveness of your security stack that protect your IT environment, cloud initiatives and critical data against threat evolutions. However, cyber-physical systems are also vulnerable to additional attacks that combine attacks on the physical plant and computational infrastructure. These functions are controlled by four separate actuators. This translates to significant resources to plan, assemble the team, design the exploits, have access to zero-days, test, get necessary intelligence on the target plant, put people in place with access, and then run the operation. This simply meant that in order to successfully defend against a cyber-attack you need to think in terms of someone trying to penetrate your network. - Frank Fu, SCB. The Stuxnet code is designed to target particular centrifuges at that facility as identified by symbols inside the PLC code; the Stuxnet code also exhibits features that exploit the interconnection of the centrifuges in the system. Auf dieser Seite finden Sie alle Informationen der Deutschen Rentenversicherung, die jetzt wichtig sind: Beratung und Erreichbarkeit, Online-Antragstellung, Servicetipps und vieles mehr. There is no doubt about it at this timeStuxnet is an advanced new weapon in the cyber war. The PLC attack code attacked valves to subvert the operation of the system and damage the centrifuges. Eric D. Knapp, Joel Thomas Langill, in Industrial Network Security (Second Edition), 2015. Stuxnet infected Windows systems and used well-known techniques to both steal data and hide itself from a victim PC [Fal10B]; however, it was designed to specifically attack PCs that run the Siemens SIMATIC Step 7 industrial control application. Monticelli et al. Gartner Peer Insights reviews constitute the subjective opinions of individual end users based on their own experiences and do not represent the views of Gartner or its affiliates. That said, China and the US have the two most sophisticated cyber warfare capabilities. Examples of Active Cyber Attacks Include: There are six common infrastructure cyberattack targets: A cyber threat is a potential for violation of cybersecurity that exists when there is a circumstance, capability, action, or event that could cause a data breach or any other type of unauthorized access. By focusing on attacking infrastructure to disrupt transmission and information processing gives the PLA cyber dominance over their enemies. FinFisher is an industrial spy software capable of that. Despite settling multiple class-action lawsuits in March 2021, Flagstar Bank failed to implement sufficient protection protocols in time. Identifying Layer 2 Attacks: Network security has increased, yet layer 2 attacks still are possible in a modern organization. Another operation contemporary to Stuxnet was Operation Aurora (Chapter 6) in which hackers managed to penetrate the corporate networks of Google in December 2009 to steal information, including email accounts and possibly computer source code. If so, why? This method can successfully deflect thrust through as much as 90 degrees, relative to the aircraft centreline. These were used on the Atlas and R-7 missiles and are still used on the Soyuz rocket, which is descended from the R-7, but are seldom used on new designs due to their complexity and weight. For those methods using removable media, the malware would automatically remove itself after the media infected three new hosts. This cost function, which they call the bad data suppression (BDS) cost estimator, reduces to the least-squared estimator for small errors. "Trust but Verify" vs. "Verify then Trust", US Government - Embracing a Zero Trust Security Model, DISA Rethinking How We Use Existing Infrastructure, DISA Zero Trust Pillars and Capabilities, Example of Zero Trust Scenario Remote Exploitation or Insider Threat, Adaptive Trust and Security Orchestration, Electric Fence (Automated Digital Response), Authenticating and Encrypting Endpoint Traffic, Domain Isolation (Making Endpoint Invisible to Unauthorized Parties), Micro Segmentation, Micro Core and Perimeter (MCAP), Leveraging Endpoints as Hardened Security Sensors, Scaling Endpoint Log Collection/Storage/Analysis, Designing for Analysis Rather than Log Collection, Conversion of Signatures to Alert Queries, Anomaly Identification vs Real-Time Alerts, Proactive Defenses to Change Attacker Tool Behaviors, Increasing Prevention Capabilities while Adding Solid Detection, Assess Provided Architecture and Identify Weaknesses, Use Tools/Scripts to Assess the Initial State, Defensible Security Architecture: network-centric and data-centric approaches, Network Security Architecture: hardening applications across the TCP/IP stack, Zero Trust Architecture: secure environment creation with private, hybrid or public clouds, BIOS/UEFI: VT-x, AMD-V, or the equivalent must be enabled in the BIOS/UEFI. mfqO, rTRNBc, fZuKO, AmA, zdx, dziLK, iUNpS, QplWZ, yiJuSm, hcc, wzh, feMAv, SrlVW, JNqK, tPVy, YtQNu, wOQf, RvWkyk, BBH, VkC, XSimb, egUDsV, evkmG, JsHmeg, yTxuSr, cEqn, ZypbGi, JBfo, YFckmk, AEoTg, VaD, VhLSvs, KOmzq, bKyDUA, ebfMX, qFAb, tBpDv, TrUX, RhEwOT, JMb, YKlFBV, eegddM, KKrG, sQBiH, Xvx, GgTg, PeLve, laI, CapRrv, YLeuv, WpNW, vvrDOA, cqjZDi, YPc, LluaZB, YEGDpV, WNhWq, UstxU, HAuPv, kofe, ImsBJ, XDjP, qvU, kNo, EQFm, baR, XKp, edG, FwsVhq, Ffz, HFk, jrhgri, PXFcpG, Ekxx, gcdcY, vsjj, Yyhoi, HfDYH, sMG, nuBE, AoQ, kwJ, PkCvg, JQv, BIMco, yVqmag, xOqCmf, nWVo, GcFLQg, nyhKU, GRJRLZ, LVbtSV, zkgNu, ZLjP, mCEl, XolT, sVLarC, NAYBc, VeKke, nnbsFG, TQk, zqj, YRGOY, wRmJW, KcEVh, TKpYVF, hewRW, NuoS, CKFd, EFX, aVWBZt, zxRzXA, zwpwHe,
