Insider threats are one of the most dangerous types of cyberattacks. They come from within an organization, and can be perpetrated by employees, contractors, or even senior executives. Insider threats can be intentional or unintentional, but they all have the potential to cause serious damage to an organization.

What are insider threats?

Insider threats can take many forms, including:

• Malicious insiders: These are malicious actors who intentionally steal or destroy data, or disrupt operations. Malicious insiders may be motivated by revenge, financial gain, or ideology.
• Negligent insiders: These are employees who accidentally expose data or cause damage through carelessness or ignorance. Negligent insiders may be unaware of the risks of their actions, or they may simply not take security seriously.
• Compromised insiders: These are employees who have been hacked or compromised by a malicious actor. Once compromised, an insider may be used to carry out an attack on their organization.

Why are insider threats so dangerous?

Insider threats are so dangerous because they are difficult to detect and prevent. Insiders have legitimate access to an organization’s systems and data, and they can use that access to cause damage. Additionally, insiders often have a deep understanding of an organization’s operations and vulnerabilities, which they can exploit to their advantage.

What are the consequences of insider threats?

Insider threats can have a devastating impact on organizations. The consequences of an insider attack can include:

• Financial losses: Insider attacks can lead to the theft of money, intellectual property, or other valuable assets.
• Reputational damage: Insider attacks can damage an organization’s reputation and erode customer trust.
• Legal liability: Insider attacks can lead to legal liability, such as lawsuits from customers or regulators.
• Operational disruption: Insider attacks can disrupt an organization’s operations, leading to lost productivity and revenue.

How to protect against insider threats

There are a number of things that organizations can do to protect against insider threats, including:

• Implement a layered security approach: This involves implementing a variety of security controls, such as physical security, access control, and data protection, to make it more difficult for insiders to carry out attacks.
• Educate employees about security: Employees should be educated about the risks of insider threats and how to protect their organization’s data.
• Monitor employee activity: Organizations should monitor employee activity for suspicious behavior. This can be done through a variety of means, such as network monitoring, email monitoring, and user behavior analytics.
• Conduct background checks on employees and contractors: Organizations should conduct background checks on employees and contractors before granting them access to sensitive systems and data.
• Have a plan in place for responding to insider attacks: Organizations should have a plan in place for responding to insider attacks. This plan should include steps for containing the damage, investigating the attack, and taking disciplinary action against the perpetrators.

Case studies of insider threats

Here are a few case studies of insider threats:

• Edward Snowden: In 2013, Edward Snowden, a former contractor for the National Security Agency (NSA), leaked classified documents to the press. The leaked documents revealed the NSA’s mass surveillance programs. Snowden’s actions had a significant impact on the NSA and on US foreign relations.
• Aaron Swartz: In 2011, Aaron Swartz, a computer programmer and activist, was arrested for downloading millions of academic journal articles from JSTOR, a subscription service for academic journals. Swartz was charged with computer fraud and theft. Swartz committed suicide in 2013 while awaiting trial.
• Martin Shkreli: In 2015, Martin Shkreli, a pharmaceutical executive, was arrested for securities fraud and conspiracy to commit securities fraud. Shkreli was accused of using money from his hedge fund to cover up losses at his pharmaceutical company. Shkreli was found guilty and sentenced to seven years in prison.

Insider threats are a serious threat to organizations of all sizes. By implementing a layered security approach, educating employees about security, monitoring employee activity, conducting background checks, and having a plan in place for responding to insider attacks, organizations can reduce their risk of becoming victims of insider threats.

Additional tips for protecting against insider threats

Here are a few additional tips for protecting against insider threats:

• Use zero-trust security: Zero-trust security is a security model that assumes that no user or device can be trusted by default. Instead, all users and devices must be verified before they are granted access to systems and data.
• Segment your network: Network segmentation is the process of dividing your network into smaller subnets. This can help to limit the damage that an insider can cause if they breach the network.
• Use data encryption: Data encryption
