基于OODA环的信息化战场信息安全保障SD建模分析?

为深入研究信息化战场信息安全保障,提高保障效能,利用OODA环理论对信息化战场信息安全保障过程进行了分析与研究,明确了观察、判断、决策和行动每个阶段的任务与事件,并运用系统动力学方法对基于OODA环的信息化战场信息安全保障过程进行建模分析和模拟仿真,仿真结果表明随着时间推移,保障方得到的信息增多,判断和决策的正确率也随之增加,OODA环周期开始减小,保障效能随之大幅提升。研究结果对于提升信息化战场信息安全保障效能具有一定的参考价值。     

Cyber War is Inevitable (Unless We Build Security In)

The information systems controlling our critical infrastructure are vulnerable to cyber attack. Cyber war is therefore inevitable unless we improve our cyber defenses. The only way to do this is by building security into systems at the design stage.     

Stranglehold: The Context,Conduct and Consequences of an American Naval Blockade of China

The mounting challenge posed by China's military modernization has highlighted the need for the United States to analyze its ability to execute a naval blockade. A blockade strategy is viable, but it would be limited to a narrow context: the United States would have to be engaged in a protracted conflict over vital interests, and it would need the support of key regional powers. The United States would also need to implement a mix between a close and distant blockade in order to avoid imperiling the conflict's strategic context. If enacted, a blockade could exact a ruinous cost on the Chinese economy and state.     

PREVENTIVE ATTACKS AGAINST NUCLEAR PROGRAMS AND THE “SUCCESS” AT OSIRAQ

Advocates of the preventive use of force against emerging nuclear, biological, or chemical programs often look to the allegedly successful 1981 Israeli airstrike against Iraqi nuclear facilities at Osiraq. According to the conventional wisdom, this attack may have prevented Iraq from going nuclear before Operation Desert Storm in 1991. This article assesses the claim that the 1981 attack substantially delayed Iraqi acquisition of nuclear weapons, both by revisiting older debates and by introducing new evidence from Iraqi scientists. The article casts doubt on the conclusion that the attack was successful for three reasons: (1) the reactor itself was not well equipped to generate plutonium for a nuclear weapon; (2) illegal plutonium production would likely have caused a cutoff in the supply of nuclear fuel and an end to weapons activities; and (3) the attack may have actually increased Saddam's commitment to acquiring weapons. These conclusions have implications for the Bush Doctrine, as the lack of success in 1981 casts doubt on the possible success of future attacks against nuclear programs.     

INTRODUCTION: THE DYNAMICS OF NUCLEAR DISARMAMENT

Decisionmaking processes leading to the acquisition of nuclear weapons by democratic states have served as the basis for theories about nuclear proliferation. In contrast, less is known about how a totalitarian regime responds to immense external pressure to abolish unconventional weapons it considers crucial for its security and survival. This article will analyze how we can explain Iraq's behavior after the passing of Resolution 1441 and during the United Nations inspections in 2002–2003.

Contracting Out Security

Private security companies (PSCs) currently receive a great deal of attention in the news media, in sensationalist reporting, and increasingly in scholarly books and articles. While the scholarly books and articles make significant contributions to our understanding of this global phenomenon, there are several impediments to analysis that must be recognized and overcome if analysis is to be improved. Three of these impediments are reviewed in this article. The author suggests that US government material is currently available to minimize impediments and offers a framework to make analytical sense of it. Since contracting out is based on contracts, and unless the complexities of awarding and managing contracts are understood, recommendations made to reform the process of contracting out security are unrealistic.

The Hunt for Martín Caballero

While the success of Colombia's fight against illegal armed groups, led by Fuerzas armadas revolucionarias de Colombia – ejército del pueblo (FARC-EP), is generally lauded as evidence of the effectiveness of both COIN doctrine and security assistance, the configuration of Colombia's counter-insurgency effort remains largely unstudied. This article will explain the success of one of those campaigns carried out principally by the Colombian marines (Colmar) in an area of northern Colombia known as the Montes de María. Contingent factors shaped the success of this campaign, beginning with the fact that the Montes de María forms an area where insurgents, relative late comers to the region, found it difficult to put down deep roots. However, operations to eradicate them were complicated by the inexperience of the Colmar, and by constraints placed by Colombia's Constitutional Court on COIN methods modeled on those successfully applied by the British in Malaya and Kenya. Therefore, Colmar officers initiated their five-year campaign by building up a base of popular support in the towns and targeting insurgent logistical networks. This bought time to strengthen the Colmar's combat and intelligence capabilities, and take the offensive that eventually isolated and killed the leader of the FARC in the Montes de María, Martín Caballero. Unfortunately, the failure of the Colombian government to follow up the Colmar victory by installing a regional and local governments viewed as legitimate by the population, and to resolve long standing land tenure issues, has meant that, so far, the Colmar looks to have delivered a tactical victory in a strategic vacuum.
