Sophisticated cybercrimes are not originating from the outside world alone. There are threat actors within your environment too, who are also becoming tech savvy. After basic internal threats and deliberate attacks by disgruntled employees, there is a greater security risk from tech savvy employees.
Insiders in fact have many advantages over the outsider attackers.
Using following techniques, insider threats can prove fatal for an organization without raising alarms.
Hence, insiders can avoid possible detection by noisy reconnaissance, malwares, and hyperactivity.
Usually, employees are given more privileges than are necessary for the fulfilment of their jobs, just to ensure convenience. In addition to these excessive privileges, oftentimes the internal access controls are misconfigured, making Corporate’s secret and confidential information accessible by employees. Neglecting the loopholes in the configuration of internal access controls is a bigger mistake than most executives will consider it to be.
Since insider threats are on the rise, not only should information be secured from outsiders, but also from the insiders who are not concerned with the information.
Acquiring any admin-level privileges, insider threats can acquire stealthy internal hacking. For instance, Edward Snowden’s elevation of system privileges can be taken as an example, using which he crafted special digital keys to disguise his activity. When he accessed the confidential information, it appeared as if another user was accessing it. He went as far as deleting system logs to avoid trails and used encryption software so that security-monitoring systems could not detect the data theft.
Organizations have this rising concern of reducing cyber risk by the insiders.
In the end, it’s not easy to spot next generation insiders. Begin with the knowledge that insider threats are already there with the knowledge of key assets and location of sensitive data. Immediate actions should now be taken to limit access to key assets, tailor user’s privileges as per job requirements, monitor and analyze behaviors, and always have someone ready to immediately respond to alerts generated by behavioral threat models.
