In the realm of cybersecurity, one of the most challenging adversaries to pinpoint is the insider threat. These individuals, typically employees, vendors, or contractors with authorized network access, operate within the shadows of security defences. Unlike external intruders, insiders are granted access, rendering traditional security measures ineffective. Recent findings underscore the escalating severity of this menace:
1. A Soaring Surge in Insider Attacks
Over the past two years, insider attacks have surged by an alarming 44%.
2. Extended Time to Detection
Detecting these covert threats now takes an average of 85 days, compared to 77 days in 2020.
3. Escalating Costs of Defense
The financial burden of addressing insider threats has risen by 34%, underlining the urgency of this issue.
Understanding the composition of insider threats is pivotal for effective mitigation. Here, we delve into four primary categories of insider threats that besiege corporate networks:
Malicious or Disgruntled Employees
Instances abound where departing employees pilfer valuable contacts or, in a vengeful act, seek to harm their employer by deploying ransomware or divulging login credentials to malevolent actors.
Careless or Negligent Employees
Unintentional breaches stem from untrained or complacent staff inadvertently sharing sensitive data on unsecured platforms or using unauthorized devices, oblivious to the potential security ramifications.
Third Parties with Network Access
Contractors, freelancers, and vendors with network access represent a legitimate insider breach risk. Vigilant screening of these entities, alongside collaboration with IT partners, is imperative to pre-empt potential data security threats.
Hackers with Stolen Credentials
Compromised login credentials pose a grave risk, with cybercriminals assuming the guise of legitimate users once they infiltrate an employee’s login information.
Mitigating insider threats requires proactive measures to avert potential breaches. Here are some effective tactics to reduce the risk:
1. Thorough Background Checks
When hiring new personnel or engaging vendors and contractors, conducting comprehensive background checks can reveal red flags indicative of malicious intent.
2. Endpoint Device Solutions
Given the prevalence of mobile devices in corporate settings, implementing endpoint management solutions becomes crucial. These solutions allow for monitoring and control of device access to safeguard resources.
3. Multi-factor Authentication & Password Security
Bolster security with multi-factor authentication, which creates an additional layer of defense against credential theft. Strengthen password policies by requiring robust, unique passwords and using business password managers.
4. Employee Data Security Training
Educate employees on proper data handling and security protocols to mitigate risks stemming from carelessness.
5. Network Monitoring
To detect anomalies swiftly, employ intelligent network monitoring, augmented by AI-enabled threat detection. This technology identifies unusual behaviors, such as excessive file downloads or remote logins.
