![]() Also discussed is the issue of reconnaissance-how to use it to conduct planning operations for future attacks, and the differences between the three reconnaissance types known as Open Source Intelligence, passive reconnaissance, and Advanced Persistent Threat. ![]() Potential sources for attacks, along with agencies that might be behind attacks, are highlighted. This chapter discusses Computer Network Exploitation basics and begins by explaining how to identify targets by gleaning information from them and identifying those to be surveilled. Jason Andress, Steve Winterfeld, in Cyber Warfare (Second Edition), 2014 AbstractĬomputer Network Exploitation refers to the ability to exploit data or information a person has gathered on a target for his or her own purposes, and it is the phase of cyber warfare being experienced globally today. ![]() You may consider that you can quickly recover from a computer outage, but if your competitor knows all your data, you can lose a great deal of value over an extended period. In short, the difference between CNA and CNE is that there is no damage to the underlying systems with CNE however, when there is damage, it could be much more critical and long lasting. When the point-of-sale (POS) systems were finally compromised, it was to the attackers' benefit for the attack to remain unknown for as long as possible, so that they could gather as many credit card numbers as possible. They then performed reconnaissance to understand the network and determine which systems needed to be compromised to accomplish their goals. In the 2012 Target hack, during which 110,000,000 credit card numbers and related information were compromised, the attackers first had to gain access to the Target network, which they did through a vendor network. When that information was divulged, further access was denied. For example, with the Snowden leaks, it was apparent that the NSA had reliable access to terrorist communications channels. With CNE, the value of the attack is frequently dependent on nobody knowing information was compromised. With CNA, although the attackers might want to maintain their anonymity, the attack itself would become obvious. In many ways, CNE is more complicated than CNA, because more effort is required for the attacks to be surreptitious. You also want the information you compromise to be accurate. There is typically a need to maintain access to continue to collect the information. To accomplish this goal, the attacker needs to gain access to the network, perform reconnaissance, identify and gain access to the relevant systems to compromise, and find and compromise the targeted information. The attacker is basically attempting to gather information. The goal is to spy in one form or another. After all, if you cannot gain and maintain access to the desired information, you cannot maintain your espionage efforts.ĬNE is essentially computer espionage. Ironically, the integrity (with the exception of the compromise of system integrity required to gain and maintain illicit access) and availability of systems are critical to a successful CNE. With CNE, there is specifically no intent to cause damage to the targeted systems. CNE is the theft of data, with no other functions affected. Ira Winkler, Araceli Treu Gomes, in Advanced Persistent Security, 2017 Computer Network ExploitationĬNE is best described as the attack on the confidentiality of the targeted computer system.
