Whether through malicious intent or inadvertent mistakes, insiders pose a formidable risk to your organization’s security.
This figure is not just a figure of speech; it is a scream that calls attention to the social issue at hand. First and foremost, it is crucial to explain the concept of insider threats for cybersecurity is one of the most concealed yet highly potent dangers for businesses.
As we get to understand what insider threats are and mean for organizations, and as a result, plan and safeguard our digital environments against insider threats.
In this article let’s see about the critical insight forces us to look at security more closely and ensure that our systems are ready to counter all dangers that may be easily seen.
What is an Insider Threat?
An insider threat is defined as the risk of insiders, who have authorized access to an organization’s IT assets, deliberately or inadvertently compromising the organization’s valuable and sensitive information and/or IT infrastructure.
These insiders can be employees in the organizations or former employees, contractors or business partners with access to the organization’s network, data or systems.
Types of Insider Threats
Malicious Insiders
Malicious insiders are people who work for the organization or who had a working relationship with it and have the intent of causing harm to the organization.
These people misuse their authorized access to the systems and information with the help of which they get personal profits, take revenge on somebody, or help competitors.Read this blog post to know Patchwork Security: Why a Layered Approach is Crucial in Today’s Threat Landscape
Some of the illegitimate behaviors of insiders are data theft, fraud, sabotage, and espionage. Insiders are also dangerous because they have intimate knowledge of the organization’s systems and thus are hard to stop.
Negligent Insiders
Negligent Insiders are those employees who are loyal and do not have malicious intent, but they compromise the organization’s security due to their negligence or ignorance.
This category is made up of employees that have been trapped by phishing, or have leaked information, or have been reluctant to adhere to some of the laid down security measures.
Despite best intentions, they are a massive security threat and a prime cause of data leakage and loss. Consciousness raising and training programs are vital to minimize the threat of negligent insiders.
Compromised Insiders
Compromised insiders are insiders who have their credentials taken by outsiders, making them a threat to the organizations.
Such attackers employ the credentials to compromise the organization’s systems and information.
The insider whose account has been compromised may not know that his or her account has been breached hence making it difficult to detect the intrusion.
It is necessary to monitor the information space continuously and use complex methods to detect threats of this type.

Common Indicators of Insider Threats
Unusual Login Times
- Insider threats are usually characterized by certain signs among which are unusual login times.
- Employees who connect during off hours, that is during the evening or on the weekends, may be trying to obtain information that is prohibited during the standard work hours.
- Login records should be checked regularly and any suspicious activity ought to be reported by the system.
Excessive Downloading of Data
- Another such indicator is frequent downloading of data. This can be noticed with employees who begin to download large amounts of files
- As they might be collecting data to use it for their next employment or to use it inappropriately.
- The strategies include embracing data loss prevention solutions that can assist in minimizing excessive transfer, thereby minimizing cases of loss.
Attempts to Access Unauthorized Areas
- Attempts at gaining access to resources which the user is not authorized for can also be considered an insider threat.
- When workers attempt to open systems, papers, or information not necessary to their positions, they may be posing a threat.
- Another aspect is to perform periodic checks of access to business information and permissions granted to employees to guarantee that they receive only the necessary data in the framework of their work.
Decreased Productivity
- Another indicator of an insider threat is reduced efficiency or unpredictable behaviour at work.
- Those employees who have a reduced rate of working, act stressed or otherwise strangely can be suffering from personal problems or can be involved in an act of sabotage.
- Managers should be educated on these behavioral changes and how they should handle them.
Impact of Insider Threats
Financial Losses
- Losses in terms of money are probably one of the most tangible effects of insider threats that can be observed in the early stages of threat development.
- losses include the amounts lost to theft, fraud and the expenses incurred due to a security infringement.
- Moreover, it can result in large costs of mitigation, fines, and insurance premiums based on the consequences of insider threats.
- The financial cost can also be high and this has an impact on the organization’s ability to generate revenue and financial solvency.
Damage to Reputation
- A final set of cost is the damage to reputation which is also a severe loss for any organization.
- Whenever an organization has a leakage of data or any other form of security breach, its image is likely to be distorted in the eyes of the customers, business associates or investors.
- Violation of trust leads to customers’ distrust, unfavorable media exposure, and brand deterioration in the long run.
- It is not easy and very time-consuming to regain the public’s trust especially after a scandal and this usually calls for publicity crusade.
Legal Implications
- Legal consequences of insider threats may include legal proceedings such as lawsuits and regulatory investigations and non-compliance with the law.
- Affected customers, employees, or business partners can sue the organizations as a result of harm caused by the cyber threats.
- There may also be financial consequences which regulatory bodies may deem fit to impose because an organization failed to protect sensitive data.
- Additional costs such as the attorney’s fees, compensations, and penalties escalate the expenses burdening the organization besides tarnishing its reputation.
Operational Disruptions
- Operational disruptions Such disruptions include the unavailability of a system because of breaches, data loss, or a disruption of key processes.
- The effects of such disruptions are that it has a ripple effect on daily business operations and this results in delayed work, low work output and low efficiency.
- In certain situations, there are disruptions which affect the functioning of the organization and cause long-term harm.
