In today’s business environment, where data, information systems, and people are a company’s most valuable assets, internal threats are becoming increasingly dangerous and sophisticated. These threats can arise from both the criminal intent of insiders and the simple carelessness or incompetence of personnel. That is why effective interaction between corporate security professionals, who are responsible for protecting the company at the organizational, behavioral, and legal levels, and IT departments, who provide technical security for digital assets, is critically important. Only through close cooperation between these teams can it be possible to create a resilient, adaptive system for detecting, preventing, and responding to internal threats that meets the challenges of the time.
- Identifying insider threats
- Insiders: employees, contractors, or partners with access to internal resources.
- Types of threats: data leakage, sabotage, fraud, unauthorized use of systems.
- Reasons: dissatisfaction, financial difficulties, negligence or ignorance of safety rules.
- Roles of IT and Security
IT professionals | Corporate security specialists |
Information systems protection | Employee behavior analysis |
Implementation of technical control measures | Conducting investigations |
Network activity monitoring | Socio-psychological assessment of personnel |
Encryption, access, logging | Development of security policies, staff training |
- Forms of cooperation
- Common response procedures: development of action algorithms when suspicious activity is detected.
- Data exchange: log files, SIEM system reports, behavioral analysis.
- Regular meetings and risk planning.
- Internal audits: checking compliance with security policies on both sides.
- Technical tools for detecting insider threats
- SIEM systems ( Security Information and Event Management )
- DLP ( Data Loss Prevention
- UEBA ( User and Entity Behavior Analytics )
- IAM ( Identity and Access Management )
- Safety culture
- Training staff in cyber hygiene issues .
- Building trust, not total control.
- “Least privileged” policies.
- Identifying “weak spots” — collaborative analytics
Synergistic approach:
- Corporate security studies motivational risks : conflicts in the team, employee loyalty.
- IT specialists analyze digital vulnerabilities : unencrypted channels, weak passwords, excessive access rights.
- Mistakes in organizing interaction: what to avoid
- Silo thinking: departments work separately, do not exchange information.
- Passive position: identifying threats only after the fact.
- Formal approach to security audits: a “check mark” rather than real analysis.
- Mistrust: when IT staff consider security services to be “spies,” and they, in turn, do not trust the techies.
- Elements of effective interaction
Element | How to implement |
Communication platform | Create a shared channel ( Slack / Teams ) where incidents are discussed |
Cross-functional trainings | Security teaches IT about social engineering, IT teaches security about the technical aspects of threats |
Risk assessment program | Joint audit: technical + behavioral analysis |
Incident management | Determine who is responsible for what at the time of the incident |
Insider attack action plan | Pre-written scenarios and role models of actions |
- The human factor is the center of risk
- Most insider threats are not technology, but people .
- Prevention:
- Checking new employees.
- Psychological support for the team.
- Anonymous complaint channels.
- Monitoring “red flags”: change in behavior, excessive curiosity about confidential information.
