Whether it’s a negligent employee or the result of espionage, insider attacks are the top concern of every organisation. They have been more frequent in the past few years. Even more alarming fact is that almost 62% of the companies experienced at least one insider attack in the last year.
That’s why it is important to take proper measures against insider attacks, as they are a serious security threat that can affect your organisation. In this article, we will discuss in detail how you can prevent insider attacks.
Protection Measures
Data protection is the key to preventing potential insider attacks. To make this happen, you must take the following measures:
- Implement Zero Trust Security
You must assume that no user in your company is trustworthy by default. Rather than granting broad access on assumptions, follow strict verification rules for all types of access.
- Enforce the Principle of Least Privilege
Grant your employees only the minimum access required for their jobs. This practice reduces the risk and potential damage from a compromised or malicious insider.
Many IT teams leverage privileged access management software to enhance security and automate access management processes. When considering a software solution, select a reliable provider, like ScreenConnect, that can be integrated with other endpoint management and security workflows.
- Use Multi-Factor Authentication
There must be multiple forms of verification for access, especially for privileged accounts. It will prevent unauthorized entry even if the credentials are stolen.
- Strengthen Access Controls
You must install a robust identity verification system in your company. A secure physical and logical access to critical infrastructure and sensitive information can prevent the likelihood of potential insider attacks.
- Eliminate Idle Accounts
You must regularly purge or disable accounts of your former employees. It is essential to prevent unauthorised access to your systems and data.
- Develop Clear Policies
Take some time to create comprehensive, documented data handling and security policies. Clearly define your expectations for employees regarding data protection and access to ensure a consistent approach to data management.
Detecting and Monitoring
Despite robust preventive measures, some insider attacks can affect your organisation’s systems and data. That’s why monitoring and detecting potential threats is essential to ensure security.
You must use advanced tools to analyse user behaviour and flag anomalies that might indicate data theft or unauthorised changes. Additionally, implement solutions that track employee action and correlate information from multiple data sources to detect suspicious activity.
Training and Culture
Your employees must know how to identify risky behaviours and understand the proper procedure for reporting them. You should educate them on recognising engineering tactics, like phishing. This will promote security awareness and help you protect your organisation from potential security threats.
However, many people think organising training sessions is an additional cost. In reality, this is not true. Fostering a learning culture and educating your employees can benefit you in the long run. It will result in a collaborative effort where all your employees are actively identifying potential vulnerabilities and protecting your company’s valuable assets.
