Insider attacks are still one of the most serious problems in cybersecurity. Consequently, the significance of continual cybersecurity and insider threat education is essential for smart company leaders. They understand that their entire workforce needs to become educated on the necessity of cybersecurity and insider threat protection, and best practices. Unfortunately, employees may not be acting deliberately, but they may be jeopardizing their company's data.
This article will closely look at the topic, tapping on everything there is to know about insider threat tactics.
An insider threat is a malicious threat to a firm that originates within the organization. Workers, former employees, contractors, or business associates with access to inside information about security, data, or computer systems could be considered insider threats.
When people think about insider threats, they usually think of rogue or dissatisfied staff intentionally committing hostile deeds. However, employees may pose an insider danger due to their ignorance or negligence, which firms fail to include in their IT security plan.
As a consequence, organizations must get prepared for any eventuality. Fortunately, as you will see later on, there are certain techniques for dealing with insider threats and preventing them in the future.
Insider threats are usually classified based on the part they play in the attack and the goal they are pursuing:
Insider Threat Techniques to Be Aware OfInsider threat techniques can get divided into four key categories:
Data theft is perhaps the most common and diverse form of insider threat tactic. Financial gain, revenge by a disgruntled employee, industrial espionage, or hacktivism are all possible motivations for obtaining sensitive information. You can also carry out this strategy in various ways, such as transmitting data to a private email account or photographing important papers.
Users with elevated access rights can take advantage of sensitive resources in various ways, including uploading data to an unprotected cloud service, creating a backdoor, and editing or deleting activity logs. Because privileged insiders have numerous opportunities to conceal their behavior, this form of insider threat is extremely difficult to identify.
Because average users' access rights are frequently limited, it can be difficult to harm an organization, but it is not impossible. A trusted user can get enough privileges to access — and abuse — protected resources if access does not get managed properly. Exploiting security software flaws and setup problems is another approach to increase access privileges.
The purpose for attempting to harm an organization's assets might range from employee retaliation for unfair treatment to a desire to blackmail a company, a competitor's division, or even a different state. Saboteurs, unlike other types of insider threat attackers, rarely take data. They would rather destroy the organization's infrastructure elements, remove or corrupt data, or physically harm business equipment.
After tapping the most common insider threat tactics, it is time for some good news. Here are some strategies for detecting and mitigating insider threats.
One of the most common insider threat detection strategies is to monitor user activities within your network. Monitoring software keeps track of overall user behavior and compares it to security policies. The program delivers an alert to security officials or IT managers when a user breaks a regulation.
Miscommunication between IT and HR is the cause of many security issues. If IT departments are not informed about layoffs promptly, they are also unaware that you must revoke access and privileges. Disgruntled ex-employees can use their credentials to steal data, erase data, and launch various attacks during this time.
When HR and IT departments communicate effectively, they may alert one another and avoid insider threat occurrences in the first place.
Conducting frequent anti-phishing training is a great method for lowering the number of pawns. You can, for example, send phishing emails to different individuals to observe who recognizes them as phishing scams and who does not. After that, you can concentrate on training people who did not recognize the email as a phishing attempt. This training can help to minimize the number of pawns available.
Many projects choose to create their threat hunting teams. A threat hunting team actively seeks out threats rather than passively reacting to occurrences after they occur. These threat hunters, who are frequently members of the security team, look for signals that could indicate data theft or other disruptions before they occur.
Technical controls, which get designed to analyze and identify questionable user behavior, can be set up by organizations. Technical controls have grown in popularity, largely due to their ability to compare user behavior to previous acts and detect abnormal behaviors.
Insider threats occur in a variety of sizes and shapes. They can be malicious or unintentional, well-intentioned or opportunistic, aggressive or quiet, hidden or obvious. Each insider threat strategy necessitates a threat detection mechanism. Using a separate dedicated tool for each threat detection method might be resource-intensive and lead to confusion in your security system.Consider Werbot in this regard.
