Defining insider attacks

Insider attacks, also known as malicious insiders or insider threat, refer to malicious activities perpetuated by internal personnel who use their legitimate access and legitimate credentials to computer systems and networks with the intent to cause harm.

This encompasses a number of criminal activities including altering data, destroying information, stealing confidential information, and installing malware with the intention of sabotaging operations. Insider attacks have potentially devastating effects across industries and organizations, making them difficult to prevent using traditional security solutions in place.

As such, organizations must implement enhanced monitoring solutions as well as additional formal risk management processes to protect against these threats.

Why are cyber security insider threats difficult to prevent?

Cyber security insider threats are among the more difficult to prevent due to the complexity of isolating which actions may be malicious. Insider threats can come from a variety of sources, whether employees or third-party contractors, and can come in the form of policy violations such as stealing data, improper use of confidential information, or sabotage.

Since these threats often arise from authorized users who have complete access to company resources and data, it can be hard to differentiate between normal activity and activity with malicious intent.

Consequently, education on how to detect and address these issues is essential for organizations seeking greater cyber security protection against malicious insiders.

The consequences of an insider attack

Insider attacks can have serious consequences for businesses, organizations, and other entities. Information theft can lead to financial data being exposed and put sensitive personnel information at risk, resulting in costly legal issues.

Moreover, malicious activity from insiders can cause irreparable damage to operations as well as a company’s reputation that may take years to repair. Organizations must be vigilant of tight security protocols and enforce strict access control systems to mitigate the risks associated with insider threats.

Training employees in data protection and regularly auditing systems are also effective countermeasures that organizations should take into consideration when dealing with potential insider threats.

Recent examples of insider attacks

In recent years, there have been several reports of insider attacks that have caused tremendous concern. In 2017, a data breach at Uber exposed personal information for 57 million people due to the actions of an insider looking to access customer files.

Also in 2017, an employee at Deloitte used privileged access to exfiltrate client records. Just this past year, a malicious insider infiltrated an Australian government agency and deleted valuable information from the organization’s servers without detection. With this rise of data protection infringements by trusted insiders, organizations must begin implementing stronger security measures to pre-empt further damage and protect customer data and intellectual property.

We have also seen a notable rise in cases of insider attacks, with a reported 33 percent increase in the first three months of 2021 alone. These assaults, which are committed by individuals who have legitimate access to an organization’s network or assets, can range from simple theft of data to more threatening acts such as espionage and sabotage.

Another example was the 2020 attack on FireEye, where malicious actors stole tools used to test cybersecurity systems and exploit them for their own ends. More recently, ransomware attacks originating from within organizations have also become more common, with hackers using illicitly gained access credentials to install malware and encrypt critical data.

Thankfully, many organizations are taking steps to mitigate such threats by creating stricter controls on employee privileges and implementing stronger authentication practices.

How to protect against an insider threat

Insider attacks can be one of the hardest-to-prevent security threats, but there are a few key steps that businesses can take to limit potential damage and stay secure.

One option is to use user privileged access management software which allows administrators to monitor what actions users are taking on the network and importantly, who they are sharing resources with. This prevents any rogue or malicious employees from accessing sensitive information they might otherwise come across while only needing limited privileges.

Security policies should also be put into place that outline the specific access rights a user has within the business system, restricting those without sufficient clearance from accessing restricted assets.

By determining a baseline of normal user behavior, you can find risky behavior. Far from all companies has these processes already in place, but there are excellent companies with highly skilled security teams to reach out to for help with insider risk management solutions. They are experienced with insider threat defense and how to handle an insider threat incident. By using a security operations center and a centralized monitoring solution it is much easier you very quickly vastly improve you security posture.

Advanced insider threat detection can also analyze entity behavior analytics and user behavioral analytics in order to help security teams detect and respond to a potential insider threat. Finally, robust identity verification protocols should be implemented at various levels to help track user activity and responses, alerting administrators when any suspicious activity is detected.

With these strategies in place, businesses can protect against potential insider attacks and keep their sensitive data safe.

Insider threat prevention tips for businesses

Prevention of insider threats must be a priority for businesses, not just in terms of financial loss but also privacy and reputation. Establishing secure protocols, policies, and procedures for handling sensitive information is the first step in protecting your business. It’s important to train employees on proper handling of company documents and use monitoring to help capture any potential risks.

Make sure employees understand the importance of physical security such as the locking of file cabinets and desk drawers, as well as taking extra precautions when working remotely with portable storage devices or computers. The use of a virtual private network (VPN) when working away from the office with company systems will also help mitigate risks.
