The Optimal Response to User Threat Detection

Finding a threat is like trying to find a needle in a haystack. There are so many contextual factors to sift through that actually finding the newest threat and eliminating it is an encumbering job. That’s why integrating some automated computing software that monitors your company’s insiders as well as user threats offers such a major benefit. As wide open as the Internet is, there is so much that can happen and does regularly happen on a regular basis and without artificial intelligence. Having a prepared incident response for the next, newest sophisticated attack is almost impossible if you’re relying on past correlations and forensics research. Special incident response software is designed to alert you in the event that a suspicious incident is logged and respond to it in a prioritized fashion compared to its possible impact. This incident response software can pinpoint the time and location of the device that caused the alert and process as much data as is necessary to you regardless of where your server is.

Responding to Security Threats in an In-House Context

We must keep in mind that insiders are just as dangerous if not more dangerous than outsiders. There is more than enough reason for a company to seek as much insurance in response to that as possible. For this reason, such risk management software has built-in ad hoc queries for countless scenarios, taking numerous factors into account as well as ad hoc queries in the event signs are detected that in one way or another resemble the most recent scams. In addition to raising employee awareness and compliance by having them sign off on policy and fraud prevention procedure, this must be complemented with stringent access control. 

Containment of Access by User 

One such software that regulates access is Window’s active directory. Active directory is a technology used to manage access for certain users and particular devices within a network. All the data that is accessed within that network comes from that encrypted directory. While some access systems are set up based on privileges, which create a layer of protection between the user and sensitive objects, user rights are designated via a different strategy – to individual employees. One example of privileged accounts is admin accounts. These administrators must go through the PAM system to get their credentials and then their privileges are authenticated and their access is logged. Active directory itself conducts machine threat analysis and analyses which users may find themselves in conflicts of interest, for instance if a user happens to the director of the department of production and the department of quality at the same time, a pair of so-called collapsing functions. 

Resolving Inefficiency and Detecting the Entire Performance Context

Individuals are only allowed to access data to provide insight that is necessary for them to be able to adequately do their jobs. Sophisticated data threat alert systems offer companies the ability to have any sensitive data automatically rejected when an employee actively sends out sensitive source code data or the personal data of customers, suppliers, or other employees. Employee activity monitoring software sends alerts in the event that employees are not efficiently working. If an employee is idle for 15 minutes, there will be a negative flag alert for that employee. This is good for the employers because he will be able to use that context to filter out the unproductive employees. Meanwhile, it’s also good for the employees because they will have fewer working hours, as there are signs pointing toward a global trend of employees serving fewer, more efficient working hours. 

Call Monitoring for Threat Containment

What this also entails is the possibility to analyze phone transcripts (on company devices and service accounts) and IM chat histories and scan them for words comprising a potential threat incident. In the event that this threat incident did materialize, the business owner could use it for self-defense or to prosecute the employee in the event of a crime. Employers have the right to monitor service accounts opened for work purposes. This is only different in the case of the employee’s personal devices and accounts.

Detecting and Logging Security Breaches

Some of the latest threats continue to be social engineering threats. The attacker may claim to be an executive in the company requesting sensitive data or the attacker may pretend to be a social network and request the user to fill in their login credentials on a fake form in which case the criminal will obtain the user’s credentials. Other attackers send downloadable links which may comprise a number of attacks: Denial-of-Service activity, SQL injection, data mining activity, a ransom attack, malware, a virus, a worm, a Trojan virus, etc. If a user notices that his computer has significantly slowed down after he downloaded a shady file, his computer is very hot, and there is visibility that the power bill has skyrocketed and this is causing users to work additional working hours, these signs have a high correlation data mining activity. This risk could be picked up ahead of time by a forensics service software connection. These penetrations could also compromise a business’ and its customers’ data. Thus, it is a must to have a visibility of phenomena in the form of graphs.

Recovery after being Hacked

If you’ve noticed that you’ve been hacked, because your social media accounts have been used to send out spam, your device is covered in ads, and there are purchases being made from the company’s bank account that you don’t recognize, recovery will take some time. First, alert your bank accounts and change all your passwords. If you already had software installed, this likely wouldn’t have gotten too far along since security measures would have responded to such irregular activity. Better yet, if you had set your devices to self destruct after they became transported a significant distance away from you, you might not have suffered any damages at all. Obviously, the next step would be to delete all the personal information off your devices and accounts, especially if you have tax information or a photo of your bank card stored on your device. If you’ve suffered significant losses, it may necessitate that you have a thorough security audit conducted. Unsubscribe from everything that you don’t remember subscribing to, inform people that you’ve been hacked, and in the event that you or they receive any e-mails from outfits you or they are not familiar with, make sure those addresses get added to the spam filter.

Activity Insight: Insider Profile Activities

For the purposes of malice and greed, users commonly misreport their expenses data or the amount of time they spend at work. Some things that are very good clues when an employer has noticed some suspicious activity is changes in his behavior and how he spends his time. The more events and data that get monitored, the more insight the business will have into its actual state of affairs. In the event that a network has been compromised, a good sign of a user who may have potentially compromised the system is a user who is leaving the organization. This is a user whose profile and activities should be resolved as being suspicious and criminal or not. In the event there is insight or an alert that an incident has already taken place, it would have given the company an edge to have already predicted this potential trend, but if a company hasn’t done so, a data forensics correlation specialist would provide it that good edge. In this event, take the time to research and gain insight on who has transferred data to a backup service, personal account, or a third-party account. Transferring to a backup service and other outside sources may be provide insight that he is trying to steal leads from the job. If that employee does exhibit some compromising or suspicious behavior, it’s worth the time to also check out the activity of the peers he associates with most at work. 

Insider System Compromise Alerts

Employee users are fairly careless, especially when it comes to not monitoring connections going on that they’re not aware of. Another suspicious activity that a specialized, insightful software would have is if employees are coming to work at suspicious times, leaving work at suspicious times, as well as how their activities and performance has differed. If an employee usually spends time working on Sundays but suddenly starts working on Saturdays, that’s another good source of potential insight. Such programs deny certain actions by employees and alert the management in such cases as an attempt to upload a file too large in size or provide an alert on an unauthorized file upload attempt to a cloud.
