You might believe you've covered all bases to protect your business from cyber threats. You've deployed the latest security solutions against external attacks, but are you equally guarded against internal risks?
Consciously or unconsciously, your employees, vendors, partners, and even yourself could potentially endanger your organization. Therefore, it's essential to focus on protecting your business from within. In this blog, we will discuss various internal threats, how to spot warning signs, and most importantly, strategies to prevent them.
Common Insider Threats
Insider threats come in multiple forms, each carrying unique hazards. Here are some common threats:
Data Theft: This occurs when an employee or someone within the organization downloads or leaks sensitive data for personal benefit or malicious purposes. It can be both physical—stealing company devices—or digital—copying sensitive information.
Example: An employee from a leading healthcare provider downloads and sells protected medical records on the dark web.
Sabotage: This involves a disgruntled employee, activist, or competitor's agent intentionally damaging, disrupting, or destroying the organization's assets by deleting critical files, infecting devices with malware, or changing passwords to lock out access.
Example: A discontented coffee shop worker tampers with a machine, causing malfunctions and loss of business.
Unauthorized Access: This involves malicious actors, like hackers or discontented employees, gaining access to vital business information. In some cases, individuals may unintentionally access sensitive data without realizing its significance.
Example: A malicious employee uses their credentials to access privileged information and leaks it to competitors.
Negligence & Error: Both negligence and errors contribute to insider threats that jeopardize security. Training can mitigate errors, while negligence requires stricter enforcement measures.
Example: An employee clicks on a harmful link and downloads malware, or misplaces a laptop containing sensitive data, compromising the company's information.
Credential Sharing: Similar to handing over your house keys to a friend, sharing confidential passwords opens up numerous possibilities, including increasing the risk of cyberattacks.
Example: An employee accesses their work email on a friend's laptop but forgets to log out. If the laptop is hacked, the company’s confidential information becomes accessible to the intruder.
Spot the Red Flags
It’s critical to detect insider threats early on. Watch for these indicative signs:
Unusual Access Patterns: An employee starts accessing confidential information irrelevant to their job role.
Excessive Data Transfers: An employee begins downloading significant amounts of customer data onto a memory stick.
Authorization Requests: Frequent requests for access to critical business information from individuals whose roles don’t require such access.
Use of Unapproved Devices: Accessing sensitive data via personal laptops or other unauthorized devices.
Disabling Security Tools: Someone in the organization disables antivirus software or firewall protections.
Behavioral Changes: An employee shows abnormal behavior such as missing deadlines or extreme stress.
Enhance Your Defenses
Follow these five steps to build a robust cybersecurity framework ensuring comprehensive protection for your business:
Implement a strong password policy and promote the use of multi-factor authentication whenever possible.
Restrict data and system access to what is necessary for each employee's role, and regularly review and update these access privileges.
Educate and train your workforce on internal threats and best security practices.
Regularly back up critical data to facilitate recovery in case of data loss incidents.
Develop an incident response plan detailing actions to take during insider threat incidents.
