If cyber threats feel like faceless intruders, you’re only considering a fraction of the risk. Insider threats pose a challenge for organizations, often catching them by surprise as they focus on securing the perimeter. There is a bright side, however. Understanding the threat landscape and developing a security plan will help you to mitigate risk and prevent cyber incidents. When designing your strategy, be sure to account for insider threats. What is an insider threat? Perhaps unsurprisingly, insider threats are threats that come from within your organization. Rather than bad actors from the outside infiltrating your network or systems, these risks refer to those initiated by someone within your organization - purposefully or as a result of human error. There are three classifications of insider threats: Malicious insider threats are those perpetrated purposefully by someone with access to your systems. This may include a disgruntled employee, a scorned former employee, or a third-party partner or contractor who has been granted permissions on your network. Negligent insider threats are often a matter of human error. Employees who click on malware links in an email or download a compromised file are responsible for these threats. Unsuspecting insider threats technically come from the outside. Yet, they rely on insiders’ naivety to succeed. For example, an employee whose login credentials are stolen or who leaves their computer unguarded may be a victim of this type of threat. Keys to identifying insider threats Once you know what types of threats exist, you must know how to detect them to mitigate the risk or address compromises as quickly as possible. Here are four key ways to identify insider threats: Monitor Third parties are the risk outliers that, unfortunately, lead to data compromise all too often. Monitoring and controlling third-party access is crucial to identifying insider threats, as contractors and partners with access to your networks can quickly become doorways to your data. Consider monitoring employee access as well. Security cameras and keystroke logging are methods some companies may choose to monitor movement and usage, though they may not suit every organization. Audit Pivotal to risk mitigation - for insider threats or those outside your network - is an ongoing auditing process. Regular audits will help understand typical behavior patterns and identify anomalies should they arise. Automated audits can run based on your parameters and schedule without much intervention from SecOps. Manual audits are also valuable for ad hoc reviews of multiple or disparate systems. Report A risk-aware culture is based on ongoing communication about threats, risks, and what to do should issues arise. It also means establishing a straightforward process for whistleblowing. SecOps, try as they might, cannot always be everywhere. Get the support of your employees by making it clear what to look out for and where to report any questionable activity they notice. Employees can also conduct self-audits with SecOps’ guidance to assess their risk level. Best practices for prevention Prevention of insider threats relies on a few key aspects. Here are some best practices to prevent threats: Use MFA The low-hanging fruit in security is establishing strong authentication methods and defining clear password practices. Enforce strong, unique passwords, and ensure users must change them regularly. Multifactor authentication (MFA) will protect your network and systems if a user ID or password is stolen or compromised. Screen candidates and new hires Granted, bad actors have |
