Use case: user behavior and insider detection
04.09.2020Back to blog list
Insider threat is a tough and quirky menace to track down and pin. User activity presents high risk when it comes to maintaining secure workflow and ensuring that systems are intact by malicious violators. Behavior anomaly discovery is an intricate mechanism which requires impeccable automated recognition of suspicious patterns and rules out any false alarms in order to respond correctly and efficiently – the solution is configured so that only a proven threat gets signalled or tweaked so that only a repeated event is alerted to. SearchInform solution reacts as an early warning system thanks to the processes of analysing correlation between user job-related tasks and actual manipulations with data and assets.
Behavior anomaly discovery and malicious insider
Another issue, besides data security, is teamwork and user mood and attitude. An insider threat as well as a threat actor are of the focal concern to risk managers finding ways to determine the best response. High risk users or malicious actors may vary and sure they can’t be simply put into the same category, so they require individual or specific approach while detecting wrongdoing and assessing potential harm to critical systems.
The ongoing investigation and file system audit guard your sensitive data from all anomalous activities including violations caused by external malicious actors who break in by logging into users’ accounts and sabotage user performance or misuse access rights, and by internal threat actors who might share passwords, making collusions and go beyond the limits of professional responsibilities seizing the competence of colleagues and gaining unauthorised access to classified information.
Properly set boundaries exclude the risks of wrongfully accessed data as tools for user behavior and insider detection imply specific assignment monitoring and establishing both a role and a task as well as ensure in-depth insight into user-entity correlation.
• The solution analyses correlation between user activity and limits within which tasks should be performed in order to prevent insider threat
• Fraud or behavior anomaly discovery and determining the best response to abnormal events
• Remediate security flaws or shortage
• Privileged user activity control, privilege abuse prevention by prompt detection and proof gathering
• Incident prioritization algorithm to determine the best response and investigate incidents efficiently
• Privileged access management and excessive privileges identification as the key measure to mitigate an insider threat
SearchInform solution allows you identify files even if their content is altered. User activity presents high risk concerning access rights management and delimitation of roles of users authorised to work with specified documents.
Sensitive data can be endangered by a malicious actor if the activity of both newly created and current accounts aren’t properly monitored so that identity theft can be discovered before an incident happens.
Insider threat triggers an in-depth investigation in case it deserves attention – the system allows you to avoid false positives and initiate automated discovery of users’ suspicious actions based on the context.
Remediation of security issues and intrusion into critical systems
Remediation should result from automated knowledge-based decision making and the strategy should be determined after a well thought-out incident response.
Security blind spots can be detected and worked on thanks to immediate capturing of unauthorised entries under the logins of those users who actually have the rights to access specific data. Threat detection depends on the response to abnormal activity occurring during off-hours when everyone is out of the office, to various users’ attempts to log into one workstation simultaneously. Searching through stale data or archived documents might serve as a red flag as someone may dig into confidential details.
Your data privacy policies should comprise notions regulating an extent of usage frequency – if a user doesn’t usually access particular files but begins to work with them quite often or accessed them a few times or even once but never had any of those documents in usage or among tasks before, he or she becomes subject to behavior anomaly discovery. The same goes about the time the files get accessed. Reports let you see when a user attempted to read, alter or copy a file disclosing accounts active during hours or days when employees don’t work.

Investigate incidents efficiently and diminish high risks
Elaborate reports will uncover the purpose for the violation, the ways and channels the incident occurred through, the account details, the location of the accessed files, their route and the new destination for storage. Privileged users are brought into focus as high risk users, privileged access is proactively investigated.
Data recovery will help you to regain the documents which were deleted or relocated, as well as to see every version of the file each time the changes were made to it.
Prompt remediation of security issues based on comprehensive risk management program allows you to control your system by knowing priorities, proactively covering and neutralising those shortages and deficiencies in your framework which come first as well as assessing those insider threats or high risk user activities which might gradually undermine the workflow.
The crucial part of access rights management is about keeping sensitive data properly hidden. Permissions should be given in accordance with the established security policies, access should be denied for users who are guilty of privilege abuse or appear to be threat actors. Each user dismissal should be followed by excluding their accounts from the list of those who are granted access, because often dismissed employees in different companies still have unimpeded way through critical systems.
