The Vulnerabilities And Cyber Kill Chain - 1243 Words

A. ICS Vulnerabilities and Cyber Kill Chain 1. Reconnaissance - Summarize plausible active gathering, passive gathering, and active reconnaissance techniques that the adversary could have executed to gain intelligence on the target in the scenario. Reconnaissance is the act of collecting background research necessary to identify and select targets. (1) Cyber reconnaissance is an important stage of a well-organized cyber-attack, and is also one of the most time-consuming activities. This phase can exploit the information gathered about the target’s weaknesses. The type of information the hacker is looking for is how to actually get in: firewall ports that are open, network hosts, services that are running. Critical information that should be obtained during the reconnaissance phase include network information, host information, security policies, and human information. â€Å"Active reconnaissance is a type of computer attack in which an intruder engages with the targeted system to gather information about vulnerabilities.† (2) This type of information gathering involves doing something on the target network, which could potentially be tracked back to you. The idea of this phase is to gather IP addresses, subnet masks, network topologies, user names, operating systems, firewalls, password requirements and change frequency. Passive reconnaissance is focused more around public information and not engaging with the targeted systems. â€Å"Typical passive reconnaissance can includeShow MoreRelatedNetwork Vulnerabilities And Cyber Kill Chain Essay1277 Words   |  6 PagesA- ICS Vulnerabilities and cyber kill chain 1. Reconnaissance This is the phase of the cyber operation in which the cyberwarriors gather information about potentials targets. This operation can be subdivided in three sub phases. The war planners provides objectives, targeters search for potential target that might achieve the war objectives, intelligence professionals gather information about the target’s weaknesses that might be exploited in an attack (Chapple Seidl, 2015, p. 5.2).

Hackers are finding more and more ways to hack into computer systems by exploiting software vulnerabilities. In addition, hackers are becoming more creative on the methods used to achieve the exploitation of these vulnerabilities. As a result, many organizations have implemented controls to detect and identify threats before hackers successfully hack into an organization and cause irreparable damage. There areRead MoreInformation Security Risk Associated With The Spccomputing Environment2003 Words   |  9 Pagesability of a threat to exploit a vulnerability or weakness†.
