What You Need to Know About Insider Threats
Today’s small businesses are faced with a variety of cyber threats and security challenges. Media publications often cover articles about the latest data breaches and attacks that arise from cybercriminals. But for small businesses, insider threats can also pose big challenges and cause great amounts of damage.
Small businesses can be particularly vulnerable to insider threats since they often have limited resources and knowledge about these risks. A recent report from TechReport, uncovered that over 31% of all data breaches in 2023 were caused by insiders. This makes recognizing and reducing such threats essential for protecting the sensitive information of your business more vital than ever before.
Insider threats can be difficult to detect, but they can result in damages to your operational and financial capabilities. Insider threat mitigation is also crucial to maintaining trust with clients and your business reputation. Let’s explore what an insider threat is, common challenges with detecting them, and ways to help you mitigate insider threats to your business.
What is an Insider Threat?
An insider threat is a security risk that an individual with authorized access to a business’s resources, systems, and/or network misuses that access. Insider threats can come from employees, contractors, vendors, suppliers, or other business partners. The harm caused by insider threats can be deliberate or accidental but will result in damage to the business.
Some of the insider threats that can occur include malicious intelligence gathering, sabotage, data exploitation, theft, fraud, data destruction, cyberattacks, and more. Insider threats can result in damages that lead to cyberattacks, data breaches, operational disruptions, legal penalties, and financial losses.
Why Are Insider Threats Difficult to Detect?
Insider threats can be difficult to detect for several reasons but it’s often because the origin of the threat often comes from inside the organization. For small businesses, this is commonly due to the higher level of trust and internal accessibility of those who work with the organization. Providing access to your resources and data can make insider threat risks hard to distinguish between normal user behavior and malicious activity.
Insider threats also have a variety of motivations and tactics to harm your business. As the growth of remote and hybrid work environments has increased attack surfaces in recent years, insider threat risks have become more significant for all businesses.
Insiders with malicious intent who have legitimate access to your business’s internal systems and data can be challenging to detect. The growth of third-party supply chains has also added to the contributing issues of insider threats. Insiders often have knowledge of your systems, networks, and security protocols while being able to blend into normal user behavior patterns. The gradual progression of an insider threat allows malicious activities to remain undetected until considerable damage has occurred.
Three Common Insider Threats for SMB
Small and midsize businesses (SMBs) can be particularly vulnerable to insider threats due to their limited resources and lack of or smaller security teams. The damage from insider threats can disrupt operations, cause financial losses, and diminish business reputations. To better understand the risks and mitigation of insider threats, it’s important to know the three most common types that can affect SMBs.
1. Negligent or Disengaged Employees
Employees can be a small business’s greatest asset or weakest link in terms of security. Negligent or disengaged employees are one of the most common types of insider threats that can harm an SMB. It typically involves an employee who is unintentionally compromising your security due to carelessness, disregard, or a lack of awareness of your security processes.
This category can include employees or other business partners who fall for phishing schemes, adopt risky security practices, disregard security policies, or not prioritize proper password security.
2. Malicious Insider Activity
Malicious insiders are also another common threat to SMBs. This type of insider threat has the deliberate goal of negatively impacting your business continuity and reputation. These insiders will intentionally misuse their access to cause harm, commonly driven by financial gain, revenge, or a sense of entitlement.
They will conduct behaviors that include data theft, espionage with external entities, and other forms of sabotage. Data theft from malicious insiders can result in customer data, financial records, or other intellectual property to be stolen for their benefit. Additionally, malicious insiders can also purposefully damage systems and destroy data which can result in downtime or loss of that data.
3. Third-Party Vendor Compromise
Third-party vendors or other business partners are another common insider threat for SMBs. This insider threat can occur when business partners with internal access to your systems or data fail to follow your standard security procedures. The more supply chain attacks increase, third-party insider threats can become a weak point in your security.
Third-party vendor compromises can be both accidental or deliberate. One of the ways third-party business partnerships can compromise your business is through mismanagement issues that lead to unauthorized access or actions resulting in damages. Additionally, security gaps in your third-party vendors that fail to implement effective security measures can result in targeted cyberattacks against your business. One of the most prolific past examples of this type of compromise was seen in the 2013 Target data breach.
How to Mitigate Insider Threats for Small Businesses?
Insider threat mitigation will require a proactive approach that involves proper access controls, continuous monitoring, and ongoing employee education through cybersecurity awareness training. By implementing effective insider threat mitigation strategies, small businesses can still safeguard their data and assets while maintaining a secure operational environment. The following are several ways that you can implement effective measures to protect your business from insider threats.
Promote a Culture of Cybersecurity Awareness
Creating a culture of cybersecurity awareness can be a first line of defense for insider threat mitigation. This can include conducting ongoing awareness training for employees with the goal of educating and informing them of continuous cyber threats. It is also important to ensure that they are aware of security best practices, measures to ensure data protection, phishing prevention, and the significance of reporting suspicious activity. Promoting a culture of awareness around insider threats and cybersecurity can empower your employees and business partners you work with to be proactive in identifying risks.
Be Proactive in Monitoring
Monitoring what is happening on your systems, devices, and networks is key to being able to pinpoint malicious activity. Monitoring is also beneficial to help spot insider threat issues and mitigate them before they cause considerable damage to your business. This can be done by implementing intrusion detection measures, authentication controls, and other tools to support spotting unusual user behavior or unauthorized access attempts.
You can also configure automated alerts for suspicious activities to help be certain that possible threats are addressed appropriately. Additionally, periodic reviews of user log data can indicate anomalies that may suggest malicious intent or unauthorized access has occurred. Implementing this proactive stance of monitoring usual activity, it can help deter malicious insiders and reduce unintentional security mistakes made by well-intentioned employees.
Maintain Good IT Hygiene
Maintaining good IT hygiene to be a crucial component of insider threat mitigation for small businesses. Implementing good IT hygiene can include ensuring that your systems and software are updated with the latest security patches. It’s also beneficial to enlist the support of firewalls to protect your network along with security software that can detect and remove malware or viruses.
Your IT safety measures should include enforcing complex password policies, requiring two-factor or multi-factor authentication for all user accounts, and developing data classification policies based on a least-privilege model. By doing this, you can ensure that those who have access to your data and resources access information based on their role on a need-to-know basis. It’s also important to make sure that access controls and policies are updated to remove duplicate or no longer relevant user accounts to prevent unauthorized access.
Prioritize Employee Satisfaction
Employee satisfaction is a crucial part of a small business. Your employees can and should play a crucial role in insider threat mitigation. You can encourage this by engaging and supporting employees in their work. Supporting and promoting quality work-life balance can also be key to increasing employee satisfaction in your company. It’s also essential to prioritize proactive communication and transparency with your employees about challenges your business may face.
Security awareness training can also be valuable to your SMB because it encourages proactiveness and incident reporting if insider threats emerge. Small businesses should also aim to help employees understand the need for specific measures to ensure insider threats are reduced significantly. Employee satisfaction can be pivotal to the success and security of your small business against insider threats.
