The insider threat problem is one of the most difficult threats to manage in cyber security. This is because it can come from a variety of sources, including employees, contractors, and even business partners. Insider threats can result in data breaches, fraud, and other types of damage to an organization. Insider threats can be difficult to detect and prevent because they often involve trusted individuals who have legitimate access to sensitive information.
Furthermore, some people are willing to do anything for a little extra cash, while others have an ideological reason or loyalty that drives them into dangerous territory.
Insider targets can vary depending upon their motivations. Usually they focus in particular on data that a person or business can easily sell in a black marketplace (e.g.., personal information of a client or employees such as credentials).
Insider threats are a serious challenge for organizations today. While there are many potential motivations for an insider to commit malicious acts, the goals of insider threats can be broadly classified into four main categories: financial gain, organizational disruption, revenge, and espionage.
Each of these categories represents a unique set of risks that must be managed in order to protect the organization from insider threats. One of the most important steps in managing insider threats is to identify the specific goal or goals that the insider is pursuing. Once the goal or goals have been identified, the organization can develop a tailored response that is designed to mitigate the risks associated with those goals. By taking a proactive approach to managing insider threats, organizations can protect themselves from the potentially devastating consequences of these threats.

Insider threats can come in many forms, but they can broadly be classified into three categories: insider negligence, insider maliciousness, and insider accidents.
Insider Negligence refers to situations where an insider fails to follow proper security protocol, resulting in a security breach. For example, an employee who fails to lock their computer when they step away from their desk may inadvertently give an adversary the opportunity to access confidential company data.
Malicious insider occurs when an insider deliberately seeks to harm their organization, either for personal gain or out of spite. An insider with malicious intent may, for example, leak sensitive information to a competitor or attempt to sabotage company systems.
Insider accidents are situations where an insider makes an honest mistake that nonetheless results in a security breach. For instance, an employee who accidentally clicks on a phishing email may unknowingly provide hackers with access to the organization’s network, or enabling public access to a sensitive file.
All three types of insider threats can pose serious risks to an organization, and it is important for businesses to take steps to protect themselves against all three. Some common measures include instituting mandatory security training for all employees and implementing strict access controls on sensitive data. By taking these and other precautions, businesses can help
According to some estimates, the dark web market for stolen credit card and personally identifiable information (PII) is enormous and valued approximately $120 billion. Even if the worth of data varies, it is still true that cybercriminals stand to profit financially if they can obtain sensitive data.
Henceforth, cybercriminals are starting to recruit employees and use them as nefarious insider threats as one method of gathering sensitive data. The healthcare sector is especially mentioned in a McAfee report as one that is troubled by this form of insider threat.
According to a survey, 20% of workers would be prepared to sell their passwords, and 44% would do it for less than $1,000. According to the SailPoint Market Pulse Survey, some employees would sell their company credentials for less than $100.
Criminals often look out for employees that demonstrate either a vulnerability that could be exploited such as
Insider threat can come from a variety of sources, including current and former employees, contractors, and third-party vendors.
While insider threats can be difficult to detect, there are a few potential insider threat indicators that may signal malicious intent. Some of the warning signs include;
Other insider threat indicators include
For example, an insider may exhibit sudden changes in behavior, such as increased absences or tardiness, or a decrease in job performance.
They may also have a sudden financial need or display an unusual interest in sensitive company information. In addition, insiders may try to gain elevated access privileges to company systems or data, or they may share confidential information with unauthorized individuals. While these behaviors alone do not necessarily indicate malicious intent, they can be red flags that warrant further investigation. By remaining vigilant for potential insider threats, organizations can help protect themselves from costly data breaches and other damage.
The threat begins at the hiring interview. Companies must build a healthy workplace to reduce the dangers posed by malicious insider behavior by their employees and educate them to prevent unintentional threats from insiders.
These techniques or methods are the basic elements of a larger framework that addresses insider threats and other cybersecurity threats.
Other countermeasures may also include:
Ex-CIA At a New York City trial, a former CIA software engineer accused of the largest theft of classified information in CIA history was found guilty.
Tesla’s Spygate Elon Musk, the founder of Tesla, informed staff via email that this insider had engaged in “very substantial and devastating sabotage” against the business. Including using fictitious usernames to make “direct code changes to the Tesla Manufacturing Operating System.”
SunTrust Insider A rogue insider may have stolen part of SunTrust major regional US bank 1.5 million clients’ personal information.
Coca-Cola trade secret theft A research engineer stole trade secrets from Coca-Cola using simple exfiltration methods, but she wasn’t discovered until she tried to steal the same information from another business.
There are many different types of threats to an organization, but only one that is hardest for security solutions: insider attacks and obtaining high fidelity insider threat indicators.
In these cases it can be difficult if not impossible to detect by traditional cyber security tools. There’s often no external sign pointing out the strange behavior of an insider threat, disgruntled employees or former employees with legitimate access privileges. And since insiders already know how things work best within the company itself, this makes malicious activity all too easy avoid detection.
Moreover, insider threats don’t exist in a vacuum; businesses must protect themselves against malicious software and ransomware targeting corporate machines and other cyber risks. Organizations can use five types of tools to minimize cyber risks, including:
