Dell.com/certification 3 Introduction Stuxnet Stuxnet is a malevolent PC worm, first revealed in 2010, though thought to have been being developed in 2005. Stuxnet targets supervisory control and data acquisition (SCADA) frameworks and is suspected liable for greatly harming the atomic program of Iran. While neither country has straightforwardly assumed responsibility, the worm is widely considered a cyberweapon constructed together by the United States and Israel. Before we get into Stuxnet let us see what precisely a PC worm is. Computer Worm Albeit neither one of the countries has straightforwardly conceded duty, the worm is generally comprehended to be a cyberweapon constructed together by the United States and Israel. Presently, before we get into Stuxnet let us see what precisely a "payload" is. Payload Normal malignant payloads may erase records on a host framework, scramble records in a ransomware assault, or exfiltrate information, for example, classified reports or passwords. The payload is the piece of transmitted information that is the real expected message. Headers and metadata are sent distinctly to empower payload conveyance. With regard to a PC infection or worm, the payload is the segment of the malware which performs vindictive activity. The term is acquired from transportation, where payload alludes to the piece of the heap that pays for transportation. The payload is the piece of the private client content which could likewise contain malware, for example, worms or infections which plays out the vindictive activity; erasing information, sending spam or scrambling information. Notwithstanding the payload, such malware additionally regularly has overhead code focused on essentially spreading itself or maintaining a strategic distance from identification. Worms spread by abusing vulnerabilities in working frameworks. Merchants with security issues supply standard security refreshes, and on the off chance that these are introduced to a machine, at that point most worms can't spread to it. In the event that a powerlessness is uncovered before the security fix discharged by the seller, a zero-day assault is conceivable. Presumably the most well-known payload for worms is to introduce an indirect access. This permits the PC to be remotely constrained by the worm creator as a "zombie". Systems of such machines are frequently alluded to as botnets and are generally utilized for a scope of vindictive purposes, including sending spam or performing Denial of Service (DoS) assaults. Zombie A zombie is a PC associated with the Internet that has been undermined by a programmer, PC infection or trojan steed program and can be utilized to perform malignant undertakings of some 2020 Dell Technologies Proven Professional Knowledge Sharing 4 sort under remote course. Botnets of zombie PCs are regularly used to spread email spam and dispatch disavowal of-administration assaults (DoS assaults). Most proprietors of "zombie" PCs are uninformed that their framework is being utilized right now. Since the proprietor will in general be uninformed, these PCs are figuratively contrasted with anecdotal zombies. An organized Distributed Denial of Service (DDoS) assault by various botnet machines additionally looks like a "zombie swarm assault", as often seen in anecdotal zombie films. Zombies can be used to lead DDoS assaults, a term which alludes to the organized flooding of target sites by huge quantities of PCs without a moment's delay. The enormous number of Internet clients making concurrent solicitations of a site's server is expected to bring about smashing and counteraction of real clients from getting to the webpage. A variation of this kind of flooding is known as circulated debasement of-administration. Submitted by "beating" zombies, appropriated corruption of-administration is the directed and periodical flooding of sites expected to back off as opposed to crash an injured individual site. The viability of this strategy springs from the way that serious flooding can be immediately distinguished and helped, yet beating zombie assaults and the subsequent

  • Iran Dossier
    30 November 2010 Last updated at 14:48 GMT Iran and EU agree new nuclear talks Iran's nuclear negotiator Saeed Jalili is to travel to Geneva for the talks Iran has agreed to hold talks on its controversial nuclear programme, the European Union has said. The talks are to take place in Geneva on 6 and 7 December, said the EU's foreign policy chief, Baroness Ashton. They will be the first high-level direct talks with Iran on the nuclear issue since October 2009. Western powers fear Iran is seeking to develop nuclear weapons, but Tehran insists its uranium enrichment programme is peaceful and legal. Baroness Ashton's office said that meetings with Iranian chief nuclear negotiator Saeed Jalili next week see the EU's foreign policy chief would lead a delegation of officials from the five permanent members of the UN Security Council - US, Russia, China, France and Britain - as well as Germany. "We've now received a response from the Iranian authorities in which they have said that Dr Jalili has accepted Catherine Ashton's proposal to meet in Geneva", a spokesman said on Tuesday. Western countries have called on Iran to stop all enrichment of uranium amid accusations that the country is pursuing a secret nuclear weapons programme. Iran's defiance has led to sanctions on the country, which says it uses nuclear technology only for peaceful purposes. As a member state of the Nuclear Proliferation Treaty (NPT), Iran says it has the right to enrich uranium to produce nuclear fuel. Iranian President Mahmoud Ahmadinejad vowed on Tuesday that his country would not make "one iota" of concessions over its nuclear rights at the meetings in Geneva.

The Limits of Military Coercion in Halting Iran’s Nuclear Weapons Programme Kunal Singh Abstract Israel believes that the use of force is essential to stopping Iran from making the nuclear bomb. A vocal section of the strategic affairs community in the United States agrees with the proposition. This brief argues that military means are unlikely to sabotage the nuclear weapons programme of an advanced-stage bomb-seeker like Iran. Moreover, use of force could be counterproductive as it can incentivise Iran’s pursuit of the bomb, and it may erode the confidence required for diplomatic negotiations that can possibly help cease the weapons programme.

A week later, an explosion at Iran’s Natanz uranium enrichment Ifacility caused a power blackout. Israel, the state most vocally opposed to the JCPOA, is widely believed to have

  • Iran: Recent Incidents Likely a Coordinated String of Deliberate Attacks
    The Cambridge Security Initiative IRAN: RECENT INCIDENTS LIKELY A COORDINATED STRING OF DELIBERATE ATTACKS JULY 2020 Richard C. Baffa Since early May, Iranian critical infrastructure and national security facilities have been subject to at least nine fires, explosions, and apparent cyberattacks; eight of these have taken place since 26 June. The nature of the targets and the short period of time in which they have occurred is unprecedented, strongly pointing to deliberate attacks and/or sabotage. Tehran has downplayed many of the incidents as accidents, but unofficially blamed the United States, Israel, and an unnamed Arab state (likely Saudi Arabia and/or the United Arab Emirates), and has vowed to retaliate. Two of the sites, the Natanz enrichment facility and Khojir military base, are highly secure national security facilities, harbouring sensitive nuclear and ballistic missile capabilities, including the IR-4 and IR-6 generation of modern centrifuges. At Natanz, an explosion and fire damaged a new, high-value centrifuge production/assembly plant on 2 July; the building is adjacent to underground fuel production facilities where the U.S. and Israel conducted the Stuxnet cyberattack a decade ago. An unnamed Middle Eastern intelligence official claimed Israel was responsible, using a powerful bomb. On 26 June, another explosion took place at Khojir missile production site, a highly secretive facility for missile engines and propellant development and testing near Tehran. In addition, on 10 July, local witnesses in Garmdarreh, west of Tehran, reported a series of explosions followed by widespread power outages. Multiple reports claimed the explosions occurred at Islamic Revolutionary Guard Corps (IRGC) missile depots, possibly the Islam IRGC Aerospace military base; there are also other military facilities, a chemical weapons research site, and power plants in the area.

The governments of the European Troika (France, Germany and the UK) and their Iranian counterpart contributed significantly to concluding the agreement and reaching common ground. This was done in order for both parties to reap the political and economic benefits from lifting the UN sanctions on Iran. This was in addition to monitoring Iran’s nuclear program. When the Trump administration decided to pull out of the nuclear deal, the European parties clung to the deal and adopted a neutral position with regard to the recriminations between the two parties (the United States and Iran) to prevent the total collapse of the deal. The policies of Russia and China clash with those of the United States. As a result, they denounced the US pullout from the deal and rejected the sanctions imposed on Iran. Along with Iranian diplomatic efforts, the three The European Position on the Nuclear Agreement: Its Significance and Future Scenarios 3 parties seek to persuade the European countries to adopt a position which is in opposition to Trump’s unilateral policies.

  • Iran's Nuclear Ambitions From
    IDENTITY AND LEGITIMACY: IRAN’S NUCLEAR AMBITIONS FROM NON- TRADITIONAL PERSPECTIVES Pupak Mohebali Doctor of Philosophy University of York Politics June 2017 Abstract This thesis examines the impact of Iranian elites’ conceptions of national identity on decisions affecting Iran's nuclear programme and the P5+1 nuclear negotiations. “Why has the development of an indigenous nuclear fuel cycle been portrayed as a unifying symbol of national identity in Iran, especially since 2002 following the revelation of clandestine nuclear activities”? This is the key research question that explores the Iranian political elites’ perspectives on nuclear policy actions. My main empirical data is elite interviews. Another valuable source of empirical data is a discourse analysis of Iranian leaders’ statements on various aspects of the nuclear programme. The major focus of the thesis is how the discourses of Iranian national identity have been influential in nuclear decision-making among the national elites. In this thesis, I examine Iranian national identity components, including Persian nationalism, Shia Islamic identity, Islamic Revolutionary ideology, and modernity and technological advancement. Traditional rationalist IR approaches, such as realism fail to explain how effective national identity is in the context of foreign policy decision-making. I thus discuss the connection between national identity, prestige and bargaining leverage using a social constructivist approach. According to constructivism, states’ cultures and identities are not established realities, but the outcomes of historical and social processes. The Iranian nuclear programme has a symbolic nature that mingles with socially constructed values. There is the need to look at Iran’s nuclear intentions not necessarily through the lens of a nuclear weapons programme, but rather through the regime’s overall nuclear aspirations.

ANALYSIS OF IRAN'S CYBER SECURITY STRATEGY WITH REGARD TO THE ATTACK AND THE DEFENSE CAPACITY Ali Burak DARICILI ABSTRACT The Stuxnet Virus was released in June 2010 and has affected Iran's nuclear facilities in Bushehr and Natanz. It was claimed that the United States of America (USA) and Israel secret services together have a role in the planning of this cyber-attack. Following this cover activity, also known as Operation Olympic Games in the literature, Iran considered the need to take serious measures in the field of cyber security and aimed to reach an effective cyber security capacity in cyber space with the investments made in 2010.

    # 56 VALDAI PAPERS September 2016 www.valdaiclub.com NUCLEAR WEAPONS IN THE CYBER AGE: NEW CHALLENGES FOR SECURITY, STRATEGY AND STABILITY Andrew Futter About the author: Andrew Futter Senior Lecturer in International Politics, Department of Politics and International Relations, University of Leicester ; Fellow of the UK Higher Education Academy The views and opinions expressed in this Paper are those of the author and do not represent the views of the Valdai Discussion Club, unless explicitly stated otherwise. NUCLEAR WEAPONS IN THE CYBER AGE: NEW CHALLENGES FOR SECURITY, STRATEGY AND STABILITY The safe, secure and reliable management of nuclear weapons has always been a complex and complicated business, plagued by uncertainty and risks. But these challenges are being magnified and aggravated by new cyber tools, dynamics and capabilities, and from the threat posed by hackers seeking to gain access to, or interfere with, nuclear systems. The challenge is myriad in its scope, and ranges from the safe, secure and reliable nuclear C2, through fresh problems for information security, proliferation, and the safeguarding of highly sensitive nuclear secrets, to new complications for strategic deterrence and escalation, and the emergence of a cyber-nuclear security dilemma. While cyber threats may not currently undermine or supersede the role of nuclear weapons as the ultimate symbol of national security, increased uncertainty about the integrity and security of these systems raises questions for nuclear force management, thinking and strategy for all nuclear-armed states. The cyber challenge is nuanced and subtle, complicating and obfuscating the intrinsic difficulties of nuclear C2 and nuclear strategy rather than fundamentally transforming them.
