What is Insider Threat?

As its name implies, an 'Insider Threat' originates inside an organization. An 'insider' is any person who has or had authorized access to or knowledge of an organization's resources, including personnel, facilities, information, equipment, networks, and systems. 'Insider threat' can manifest from malicious, complacent, negligent or unintentional acts that negatively affect the integrity, confidentiality, and availability of the organization, its data, personnel, or facilities. Certainly, 'Insider Threat' can be an activity by a bad actor employee, but can also arise from an inadvertent or unknowing action inside an organization (such as an employee who unintentionally opens a phishing email or clicks on a malicious link).

Rising Frequency; Rising Costs.

Protecting against 'Insider Threat' is a data security concern for all organizations. The realities facing organizations today include:

  • The frequency and cost of preventing insider attacks is rising;
  • User negligence is the most common cause of a data breach; and
  • Insider threat deterrence must become a key element in a cybersecurity posture.

According to a 2020 study1, the average global cost of insider threats rose by 31% in two years and the frequency of these incidents spiked by 47% in the same time period. The risk is also present for small and medium sized businesses (SMBs). While 72% of organizations reported an increase in insider attacks in 2020, 66% of key decision makers in SMBs do not think breaches are likely to occur. Only 14% of SMBs have any kind of breach defenses in place; the rest are vulnerable to potentially devastating cyberattacks2. While daunting, the reality of modern business dictates that companies of all sizes, in all industries, must be cognizant of cybersecurity issues and prepare accordingly.

How can your company guard against Insider Threat?

The following is a brief list of action items your company should implement to address 'Insider Threat':

  • Put it in writing – An organization's security policy should include procedures to prevent and detect misuse of company resources, guidelines for conducting insider investigations, and the potential consequences to the individual. Written policies not only preserve continuity, but also clearly outline rules and expectations in the organization.
  • Train and educate – The Identity Management Institute states that employee education remains key to breach prevention, including cybersecurity awareness during onboarding and routine drills to practice attack and breach responses.
  • Dictate Acceptable Use – An organization should detail an organization's rules and expectations regarding technology use. This includes considering acceptable behavior on networks and devices.
  • Be transparent about employee privacy expectations - Organizations need to balance reducing insider threats and protecting employee privacy. Communicate and educate employees regarding the security policy and IT rules. Explain the program's objectives, while training employees about their role in security.
  • Get Technical – Invest in IT and consult with legal and technical cybersecurity professionals to find a solution that works for your organization.

Prudent businesses will create and maintain written policies as it relates to cybersecurity and data protection. BMD can assist in crafting the policies and identifying proper security frameworks and connecting you with technical experts to implement.
