About Course

This course provides learners with a baseline understanding of common cyber security threats, vulnerabilities, and risks. An overview of how basic cyber attacks are constructed and applied to real systems is also included. Examples include simple Unix kernel hacks, Internet worms, and Trojan horses in software utilities. Network attacks such as distributed denial of service (DDOS) and botnet- attacks are also described and illustrated using real examples from the past couple of decades. Familiar analytic models are outlined such as the confidentiality/integrity/availability (CIA) security threat framework, and examples are used to illustrate how these different types of threats can degrade real assets. The course also includes an introduction to basic cyber security risk analysis, with an overview of how threat-asset matrices can be used to prioritize risk decisions. Threats, vulnerabilities, and attacks are examined and mapped in the context of system security engineering methodologies.

Course Introduction

Introduction to Cyber Attacks This course will introduce basic concepts such as encryption methods and authentication methods, using common standards and protocols such as HTTP, HTTPS, and SMS. We will start with basic algorithms such as DES, AES, and RSA and the standard Bitcoin algorithm, XOR, which are commonly used in cryptographic standards. We will also look at common standards used to verify transactions and we will use a variety of standards including those requiring a digital signature, those based on MD5, SHA1, and RMD160. We then introduce the cryptographic standards for key material, public key, and public encryption. We will look at common standards to verify operations such as HDFS, HMAC, RSA, and PKCS#. We will also look at the algorithms used to construct a hash table, MD5, and HMAC. We will also look at the standard cryptographic hash functions, SHA1, RSA, and PKCS#. We will also look at common standards and protocols that are used to verify operations such as RSA, PKCS#, and HMAC. We will also look at the standard cryptographic hash functions, SHA1, RSA, and PKCS#. Completing this course will give you a strong foundation in the fundamentals of cryptographic software and how to secure your system from various types of attacks, including those from malicious software. This course requires some prior knowledge of computer programming and basic cryptographic algorithms. An additional 60 hours of study are required for a certificate. The instructor of this course

July 2009 cyber attacks The July 2009 cyber attacks were a series of coordinated cyber attacks against major government, news media, and financial websites in South Korea and the United States. The attacks involved the activation of a botnet—a large number of hijacked computers—that maliciously accessed targeted websites with the intention of causing their servers to overload due to the influx of traffic, known as a DDoS attack. Most of the hijacked computers were located in South Korea. The estimated number of the hijacked computers varies widely; around 20,000 according to the South Korean National Intelligence Service, around 50,000 according to Symantec's Security Technology Response group, and more than 166,000 according to a Vietnamese computer security researcher who analyzed the log files of the two servers the attackers controlled.
Cyber-attack In detail, there are a number of techniques to utilize in cyber-attacks and a variety of ways to administer them to individuals or establishments on a broader scale. Attacks are broken down into two categories, Syntactic attacks and Semantic attacks. Syntactic attacks are straight forward; it is considered malicious software which includes viruses, worms, and Trojan horses.
Cyber-attack In response to cyber-attacks on April 1, 2015, President Obama issued an Executive Order establishing the first-ever economic sanctions. The Executive Order will impact individuals and entities ("designees") responsible for cyber-attacks that threaten the national security, foreign policy, economic health, or financial stability of the US. Specifically, the Executive Order authorizes the Treasury Department to freeze designees' assets.
Democratic Congressional Campaign Committee cyber attacks CrowdStrike assisted with efforts to deal with the DCCC breach. There is significant concern that the Russians are attempting to influence the 2016 Presidential campaign. Russian cyber intrusions into United States government and private sector computer systems significantly increased after the U.S, imposed sanctions on Russia after its invasion of the Crimea in Ukraine. It has been President Obama's preference to publicize cyber attacks.
Cyber-attack Three factors contribute to why cyber-attacks are launched against a state or an individual: the fear factor, spectacular factor, and vulnerability factor.
Cyber-security regulation A cybersecurity regulation comprises directives that safeguards information technology and computer systems with the purpose of forcing companies and organizations to protect their systems and information from cyber-attacks. Cyber-attacks include viruses, worms, Trojan horses, phishing, denial of service (DOS) attacks, unauthorized access (stealing intellectual property or confidential information) and control system attacks. There are numerous measures available to prevent cyber-attacks. Cyber-security measures include firewalls, anti-virus software, intrusion detection and prevention systems, encryption and login passwords. There have been attempts to improve cybersecurity through regulation and collaborative efforts between government and the private-sector to encourage voluntary improvements to cybersecurity. Industry regulators including banking regulators have taken notice of the risk from cybersecurity and have either begun or are planning to begin to include cybersecurity as an aspect of regulatory examinations.
July 2009 cyber attacks It is not known who is behind the attacks. Reports indicate that the type of attacks being used, commonly known as distributed denial-of-service attacks, were unsophisticated. Given the prolonged nature of the attacks, they are being recognized as a more coordinated and organized series of attacks. According to the South Korean National Intelligence Service, the source of the attacks was tracked down and the government activated an emergency cyber-terror response team who blocked access to five host sites containing the malicious code and 86 websites that downloaded the code, located in 16 countries, including the United States, Guatemala, Japan and the People's Republic of China, but North Korea was not among them. Later, it has been discovered that the malicious code responsible for causing the attack, identified as W32.Dozer, is programmed to destroy data on infected computers and to prevent the computers from being rebooted. South Korean police are analyzing a sample of the thousands of computers used to crash websites, stating that there is "various evidence" of North Korean involvement, but said they may not find the culprit. Security experts said that the attack re-used code from the Mydoom worm. One analyst thinks that the attacks likely came from the United Kingdom.
Cyber-Insurance As of 2014, 90% of the cyber-insurance premium volume was covering exposure in the United States. Although at least 50 insurance companies have cyber-insurance product offerings, the actual writing is concentrated within a group of five underwriters. Many insurance companies have been hesitant to enter this coverage market, as sound actuarial data for the cyber exposure is non-existent. Hampering the development of this actuarial data is inadequate disclosure regarding cyber attacks by those affected.
Cyber-attack According to "Homeland Preparedness News", many mid-sized U.S. companies have a difficult time defending their systems against cyber attacks. Around 80 percent of assets vulnerable to a cyber attack are owned by private companies and organizations. Former New York State Deputy Secretary for Public Safety Michael Balboni said that private entities "do not have the type of capability, bandwidth, interest or experience to develop a proactive cyber analysis."
Cyber-attack Cyber-attack is any type of offensive maneuver employed by nation-states, individuals, groups, or organizations that targets computer information systems, infrastructures, computer networks, and/or personal computer devices by various means of malicious acts usually originating from an anonymous source that either steals, alters, or destroys a specified target by hacking into a susceptible system. These can be labeled as either a cyber campaign, cyberwarfare or cyberterrorism in different context. Cyber-attacks can range from installing spyware on a PC to attempts to destroy the infrastructure of entire nations. Cyber-attacks have become increasingly sophisticated and dangerous as the Stuxnet worm recently demonstrated. User behavior analytics and SIEM are used to prevent these attacks.
Democratic National Committee cyber attacks The Democratic National Committee cyber attacks took place in 2015 and 2016, in which computer hackers infiltrated the Democratic National Committee (DNC) computer network, leading to a data breach. Cybersecurity experts, as well as the U.S. government, stated that the cyberespionage was the work of Russian intelligence agencies.
Cyber-attack In the West, the United States provides a different "tone of voice" when cyberwarfare is on the tip of everyone's tongue. The United States provides security plans strictly in the response to cyberwarfare, basically going on the defensive when they are being attacked by devious cyber methods. In the U.S., the responsibility of cybersecurity is divided between the Department of Homeland Security, the Federal Bureau of Investigation, and the Department of Defense. In recent years, a new department was created to specifically tend to cyber threats, this department is known as Cyber Command. Cyber Command is a military subcommand under US Strategic Command and is responsible for dealing with threats to the military cyber infrastructure. Cyber Command's service elements include Army Forces Cyber Command, the Twenty-fourth Air Force, Fleet Cyber Command and Marine Forces Cyber Command. It ensures that the President can navigate and control information systems and that he also has military options available when defense of the nation needs to be enacted in cyberspace. Individuals at Cyber Command must pay attention to state and non-state actors who are developing cyberwarfare capabilities in conducting cyber espionage and other cyber-attacks against the nation and its allies. Cyber Command seeks to be a deterrence factor to dissuade potential adversaries from attacking the U.S., while being a multi-faceted department in conducting cyber operations of its own.

List of cyber-attacks These attacks relate to inflicting damage on specific organizations.
List of cyber-attacks These attacks relate to stealing information from/about government organizations.
Cyber-attack Once a cyber-attack has been initiated, there are certain targets that need to be attacked to cripple the opponent. Certain infrastructures as targets have been highlighted as critical infrastructures in time of conflict that can severely cripple a nation. Control systems, energy resources, finance, telecommunications, transportation, and water facilities are seen as critical infrastructure targets during conflict. A new report on the industrial cybersecurity problems, produced by the British Columbia Institute of Technology, and the PA Consulting Group, using data from as far back as 1981, reportedly has found a 10-fold increase in the number of successful cyber-attacks on infrastructure Supervisory Control and Data Acquisition (SCADA) systems since 2000. Cyber-attacks that have an adverse physical effect are known as cyber-physical attacks.
Democratic National Committee cyber attacks Cyber attacks that successfully penetrated the DNC computing system began in 2015. Attacks by "Cozy Bear" began in the summer of 2015. Attacks by "Fancy Bear" began in April 2016. It was after the "Fancy Bear" group began their activities that the compromised system became apparent. The groups were presumed to have been spying on communications, stealing opposition research on Donald Trump, as well as reading all email and chats. Both were finally identified by CrowdStrike in May 2016. Both groups of intruders were successfully expelled from the DNC systems within hours after detection. These attacks are considered to be part of a group of recent attacks targeting U.S. government departments and several political organizations, including 2016 campaign organizations.
Cyber attack during the Paris G20 Summit Cyber attacks in France generally include attacks on websites by DDoS attacks as well as malware. Attacks have so far been to the civil and private sectors instead of the military.
List of cyber-attacks These attacks relate to stealing data from corporations related to proprietary methods or emerging products/services.
National Strategy to Secure Cyberspace The National Strategy to Secure Cyberspace identifies three strategic objectives: (1) Prevent cyber attacks against America's critical infrastructures; (2) Reduce national vulnerability to cyber attacks; and (3) Minimize damage and recovery time from cyber attacks that do occur. To meet these objectives, the National Strategy outlines five national priorities: The first priority, the creation of a National Cyberspace Security Response System, focuses on improving the government’s response to cyberspace security incidents and reducing the potential damage from such events. The second, third, and fourth priorities (the development of a National Cyberspace Security Threat and Vulnerability Reduction Program, the creation of a National Cyberspace Security Awareness and Training Program, the necessity of Securing Governments' Cyberspace) aim to reduce threats from, and vulnerabilities to, cyber attacks. The fifth priority, the establishment of a system of National Security and International Cyberspace Security Cooperation, intends to prevent cyber attacks that could impact national security assets and to improve the international management of and response to such attacks.
