A malicious insider has access to sensitive information and has no reason to fear being discovered, since many organizations ignore insider network traffic due to its high abundance.Ī medium sized organization would have nearly 20,000 devices connected to the network. When insiders steal intellectual property, they usually act within a 30-day window, says Mike Hanley, who coauthored the CERT paper entitled “Insider Threat Control: Using Centralized Logging to Detect Data Exfiltration Near Insider Termination.” In the case of an APT attack, the attacker identifies an entry point to bypass perimeter defenses and then exfiltrate data from internal network. A major percentage of insiders have access to company data that they shouldn’t be able to see. ![]() This individual used his privileged access to that customer’s network to steal sensitive data before taking a job at a competitive semiconductor company and then attempting to use that data for competitive advantage. The example cites an employee of a computer networking company with access to a customer’s network – in this case, a semiconductor company. ![]() There is also a high growth in unintentional insider threats. Dawn Cappelli, formerly of the CERT Insider Threat Center at Carnegie Mellon University, gives an example of an outsider becoming an insider threat. CERT Insider Threat Center has been looking at malicious insider threats, but we’re now starting to include non-malicious insider threats and we’re about to actually start a new study of those types of insider threats. Over the past several years, the CERT Insider Threat Center has conducted empirical research and analysis to develop and transition socio-technical solutions to combat insider cyber-threats. Who is ignored the most, insider or outsider attackers? Vormetric recently released the results of its 2015 Vormetric Insider Threat Report, that found 92 percent of IT leaders felt their organizations were either somewhat vulnerable to insider threats, while 49 percent said they felt very or extremely vulnerable to insider threats. Insider threats aren’t just employees, they can also be contractors, vendors, or even volunteers that come in and work in the organization. In the other hand, an Outsider threat occurs when an individual or a group seeks to gain protected information by infiltrating and taking over profile of a trusted user from outside the organization. An Insider threat can be defined as ‘a current or former employee, contractor or other business partner with access to the organization’s network, system or data and intentionally misuses them or whose access results in misuse’. ![]() Before getting a deep understanding of these threats, we first need to define what we mean by the term “ Malicious Insider” or “ Insider Threat.” Firstly, an Insider is an individual with privileged access to an IT system in an organization.
