Insider threat programmes started with counter-espionage cases in the government. Today, insider threat programmes have become a more common practice in all industries, as companies understand the risks associated with not having one. To build a programme, you must first understand what an insider threat is.
An insider threat is an employee, contractor, visitor or other insider who have been granted physical or logical access to a company that can cause extensive damage. Damage ranges from emotional or physical injury, to personnel, financial and reputational loss to data loss/manipulation or destruction of assets.
Financial and confidential information
While malicious insiders only make up 22% of the threats, they have the most impact on an organisation
Most threats are derived from the accidental insider. For example, it’s the person who is working on a competitive sales pitch on an airplane and is plugging in financial and confidential information. They are working hard, yet their company’s information is exposed to everyone around them. Another type of insider, the compromised insider, is the person who accidentally downloaded malware when clicking on a fake, urgent email, exposing their information.
Malicious insiders cause the greatest concerns. These are the rogue employees who may feel threatened. They may turn violent or take action to damage the company. Or you have the criminal actor employees who are truly malicious and have been hired or bribed by another company to gather intel. Their goal is to gather data and assets to cause damage for a specific purpose. While malicious insiders only make up 22% of the threats, they have the most impact on an organisation. They can cause brand and financial damage, along with physical and mental damage.
Insider threat programme
Once you determine you need an insider threat programme, you need to build a business case and support it with requirements. Depending on your industry, you can start with regulatory requirements such as HIPAA, NERC CIP, PCI, etc. Talk to your regulator and get their input.
Everyone needs to be onboard, understand the intricacies of enacting a programme
Next, get a top to bottom risk assessment to learn your organisation’s risks. A risk assessment will help you prioritise your risks and provide recommendations about what you need to include in your programme.
Begin by meeting with senior leadership, including your CEO to discuss expectations. Creating an insider threat programme will change the company culture, and the CEO must understand the gravity of his/her decision before moving forward. Everyone needs to be onboard, understand the intricacies of enacting a programme and support it before its implemented.
Determining the level of monitoring
The size and complexity of your company will determine the type of programme needed. One size does not fit all. It will determine what technologies are required and how much personnel is needed to execute the programme. The company must determine what level of monitoring is needed to meet their goals.
After the leadership team decides, form a steering committee that includes someone from legal, HR and IT. Other departments can join as necessary. This team sets up the structure, lays out the plan, determines the budget and what type of technologies are needed. For small companies, the best value is education. Educate your employees about the programme, build the culture and promote awareness. Teach employees about the behaviours you are looking for and how to report them.
Behavioural analysis software
Every company is different and you need to determine what will gain employee support
The steering committee will need to decide what is out of scope. Every company is different and you need to determine what will gain employee support. The tools put in place cannot monitor employee productivity (web surfing). That is out of scope and will disrupt the company culture.
What technology does your organisation need to detect insider threats? Organisations need software solutions that monitor, aggregate and analyse data to identify potential threats. Behavioural analysis software looks at patterns of behaviour and identifies anomalies. Use business intelligence/data analytics solutions to solve this challenge. This solution learns the normal behaviour of people and notifies security staff when behaviour changes. This is done by setting a set risk score. Once the score crosses a determined threshold, an alert is triggered.
Case and incident management tools
Predictive analytics technology reviews behaviours and identifies sensitive areas of companies (pharmacies, server rooms) or files (HR, finance, development). If it sees anomalous behaviour, it can predict behaviours. It can determine if someone is going to take data. It helps companies take steps to get ahead of bad behaviour.
If an employee sends hostile emails, they are picked up and an alert is triggered
User sentiment detection software can work in real time. If an employee sends hostile emails, they are picked up and an alert is triggered. The SOC and HR are notified and security dispatched. Depending on how a company has this process set-up, it could potentially save lives. Now that your organisation has all this data, how do you pull it together? Case and incident management tools can pool data points and create threat dashboards.
Cyber detection system with access control
An integrated security system is recommended to be successful. It will eliminate bubbles and share data to see real-time patterns. If HR, security and compliance departments are doing investigations, they can consolidate systems into the same tool to have better data aggregation. Companies can link their IT/cyber detection system with access control. Deploying a true, integrated, open system provides a better insider threat programme.
Big companies should invest in trained counterintelligence investigators to operate the programme. They can help identify the sensitive areas, identify who the people are that have the most access to them, or are in a position to do the greatest amount of harm to the company and who to put mitigation plans around to protect them. They also run the investigations.
Potential risky behaviour
Using the right technology along with thorough processes will result in a successful programme
You need to detect which individuals are interacting with information systems that pose the greatest potential risk. You need to rapidly and thoroughly understand the user’s potential risky behaviour and the context around it. Context is important. You need to decide what to investigate and make it clear to employees. Otherwise you will create a negative culture at your company.
Develop a security-aware culture. Involve the crowd. Get an app so if someone sees something they can say something. IT should not run the insider threat programme. IT is the most privileged department in an organisation. If something goes wrong with an IT person, they have the most ability to do harm and cover their tracks. They need to be an important partner, but don’t let them have ownership and don’t let their administrators have access.
Educating your employees and creating a positive culture around an insider threat programme takes time and patience. Using the right technology along with thorough processes will result in a successful programme. It’s okay to start small and build.
