WEB THREATS, SECURITY, and Ddos Due to the Constantly Changing Threat Landscape, Keeping Corporate Networks Secure Is Particularly Tricky These Days Sponsored by WEB THREATS, SECURITY, AND DDoS Due to the constantly changing threat landscape, keeping corporate networks secure is particularly tricky these days. Threats continue to increase and evolve as attackers attempt to stay one step ahead of their targets, employing new technology, social engineering scams, and the element of surprise. Distributed Denial-of-Service (DDoS) attacks continue to plague organizations, while newer strategies such as advanced persistent threats (APTs) and spear phishing are becoming more common. In these articles, Network World and its sister publications CSO, CIO, InfoWorld, and Computerworld offer news, advice, and commentary on securing modern enterprise IT environments.

Most common targets are: Government agencies • Government agencies are targeted by Foreign Intelligence Services (FIS) • APTs can be used for theft of military level secrets and in cyber warfare for destabilization along with conventional warfare • 2007 McAfee report stated approximately 120 countries are trying to create weaponized internet capabilities • Example: The Russia-Georgia war of 2008 was the first example of a APT coinciding with conventional warfare.

Global communication at the speed of light has become a great asset to both businesses and private citizens. However, there is a dark side to the age we live in as it allows terrorist groups to communicate, plan, fund, recruit, and spread their message to the world. Given the relative anonymity the Internet provides, many law enforcement and security agencies investigations are hindered in not only locating would be terrorists but also in disrupting their operations.

  • Analyzing the Evolution of China's Cyber Espionage Campaigns
    Getting Harder to Catch Analyzing the Evolution of China’s Cyber Espionage Campaigns against the United States through a Case Study of APT1 -------- Winnona DeSombre – Comp116 Security Final Paper Advisor: Ming Chow 1. Abstract The relationship between China and the United States is arguably one of the more thorny dynamics in the sphere of international politics, complicated further by each country’s increasing cyber espionage and cyber warfare capabilities. As early as 2007, the US-China Economic and Security Review Commission has labeled China’s espionage efforts “the single greatest risk to the security of American technologies”1. However, as cyber security is a relatively new field in international relations, there is little set precedence for pressing charges or taking other action against individuals or groups conducting cyber attacks or espionage. This paper is composed of three parts: part one contains an overview of China-US relations within the context of the cyber realm and dilemmas in the international sphere regarding formulation of cyber security policy. Part two is a case study of the hacker unit APT1, a hacker unit argued to be the Chinese People’s Liberation Army Unit 61398, which covers both APT1’s history and an analysis of its cyber espionage campaigns. Part three reviews the general trends of APT1 within the context of the 2015 US-China Cyber Agreement and China-US relations regarding cyber security in general, and how the trends can possibly impact future actions of international actors and state-sponsored hacker groups. 2. To the Community: Defining Critical Infrastructure & Setting Policy Boundaries Policy often moves at a slower pace than technical innovation, especially when compared to the exponential rates of technological change in cyber capabilities.

  • Twitter Taken Down by Ddos Attack August 2009
    the Availability Digest www.availabilitydigest.com Twitter Taken Down by DDoS Attack August 2009 On Thursday, August 6, 2009, the Twitter social networking site went down. It suffered repeated outages, timeouts, and serious slowdowns for at least two days. What caused this failure? To add to the mystery, Facebook and LiveJournal simultaneously had similar problems. Were these outages somehow related? They occurred at about the same time as the 2009 Defcon 17 hackers conference held from July 30th to August 2nd. Could this have been some misguided mischief? But first, what is Twitter? For those who haven’t yet become addicted, Twitter is a microblogging social networking site that allows users to communicate what they are doing to their “followers” at any time via 140-character text messages, or “tweets.” Twitter was born in 2006 and has exploded in use. It currently has about five-million registered users, and an estimated 45 million people follow these users via their tweets. Twitter sprung into the mainstream when Republican presidential candidate John McCain joined the 21st century technology by embracing tweeting following the 2008 U.S. presidential election. Even more recently, and perhaps more importantly, Twitter was the primary communication mechanism to the rest of the world from those Iranians participating in the major rallies decrying the recent Iranian presidential election process. The untimely death of Michael Jackson also saw a massive increase in tweet volume. The Twitter Outage Access to Twitter Lost Twitter has not been known for its availability record. Pingdom, a web-site monitoring service,1 reports that Twitter was down for 84 hours in 2008, achieving only a 99% uptime.2 It should be noted, however, that Twitter is working hard to improve this record; and its uptime improved significantly in the second half of 2008.
