Computer security is crucial in today's world, where sensitive information is frequently stored and transmitted. While organisations typically focus on preventing unauthorised access to data from external sources, they sometimes overlook egress - the unauthorised transfer of data from within the organisation to the outside world.
In this post, we will discuss egress and explore ways to create information barriers through the use of technology and training.
Understanding egress and its risks
Egress refers to the unauthorised transfer of data from within an organisation to external parties or entities. It can occur in a number of ways, including email, file transfers, and instant messaging. When data is transferred outside an organisation's control, it becomes vulnerable to unauthorised access, which can lead to significant consequences, including financial loss, legal liability, and reputational damage.
Preventing egress with technology
Organisations can use technology to prevent egress by limiting access to sensitive data and systems. One of the most common methods is access control which restricts access to specific data or systems within an organisation. Access controls can be implemented through the use of passwords, biometric authentication, or other forms of authentication. By limiting access to sensitive data, organisations can prevent the kinds of problems that arise from the unauthorised access and transfer of that data.
Another method of preventing egress is air-gapping, which physically separates a computer or network from the internet or any other external network. This can prevent data from being transferred outside the organisation's control, but it can also limit the ability of individuals within the organisation to access necessary information.
Limitations of technology-based egress prevention
While technology-based egress prevention measures can be effective, they can also have limitations. For example, they may limit the ability of individuals within an organisation to access necessary data or communicate effectively with individuals outside of the organisation. Additionally, they can be costly to implement and maintain, requiring significant resources and expertise.
Preventing egress with employee training
To address the limitations of technology-based egress prevention measures, organisations can also focus on training and educating their employees. By providing training on best practices for computer security and egress prevention, organisations can empower their employees to be proactive in preventing data breaches and unauthorised data transfer.
Employee training can include best practices for password management, identification and reporting of suspicious activity, and risks associated with sharing sensitive information outside of the organisation. By providing this training, organisations can create a culture of security awareness that can help prevent egress and other forms of data breaches.
Conclusion
Egress is a significant threat to computer security that can lead to financial loss, legal liability, and damage to an organisation's reputation. Organisations can prevent egress through the use of technology-based measures such as access controls and air-gapping, but these measures can have limitations. Employee training and education on best practices for computer security and egress prevention can also help prevent data breaches and unauthorised data transfer. By taking a proactive approach to egress prevention, organisations can protect their sensitive data and maintain their reputation in an increasingly connected world.
