Understanding egress in computer security

As we become more reliant on technology, the importance of computer security has become increasingly clear. We hear about data breaches and hacking incidents on a regular basis, making it even more essential that we take steps to protect ourselves and our data. One aspect of computer security that often gets overlooked is egress, or the ability for data to leave a network. In this article, we’ll take a closer the relationship between egress and information barriers.

About barriers of information

So, what are information barriers? This is a term used to describe policies and procedures that are put in place to prevent the unauthorised flow of information within an organisation. These barriers are designed to prevent conflicts of interest and to protect sensitive information from being shared with unauthorised individuals. Information barriers can take many forms, such as physical barriers (like locked doors), technological barriers (like firewalls and access controls), and procedural barriers (like requiring multiple levels of approval before sensitive information can be shared).

Egress and information barriers

Egress and information barriers are closely related, as both involve the movement of data within an organisation. Information barriers can be used to limit the flow of information to only those who need to know it, which can help to reduce the risk of data breaches. For example, if an employee in the finance department needs to share sensitive financial information with a client, they may only be able to do so through a secure file-sharing system that is accessible only to authorized parties.

However, information barriers can also make egress more difficult, which can be a challenge for businesses that rely on the free flow of information. For example, if an employee needs to share a large file with a client, they may be unable to do so because of restrictions placed on file sharing by the organisation’s IT department. This can be frustrating for employees and can slow down business processes.

How to balance egress and information barriers

Balancing egress and information barriers can be a tricky task, as organisations need to find a way to allow the free flow of information while also protecting sensitive data. There are several steps that businesses can take to achieve this balance.

One such step is to create clear policies and procedures around egress and information barriers. This can help to ensure that everyone in the organisation understands the importance of data security and knows what steps to take to protect sensitive information. Another step is to use technology to enforce information barriers, including firewalls, access controls, and other security measures that can help to prevent unauthorised access to sensitive data.

Providing training and support for employees can also be effective. Employees need to understand the importance of data security and how to use the tools and technologies that are available to them to protect sensitive information. Finally, businesses should regularly review and update policies and procedures. The threat landscape is constantly evolving, and organisations need to stay up-to-date with the latest threats and vulnerabilities in order to protect themselves from data breaches.


Egress is an important function in many businesses and organisations, but it also poses a significant security risk. By implementing information barriers and taking steps to balance egress with data security, businesses can protect themselves from data breaches and other security incidents. As technology continues to evolve, it’s important that businesses stay vigilant and proactive in their efforts to protect sensitive information.
