The Open Systems Interconnection (OSI) model is a conceptual framework developed by the International Standards Organization (ISO). It has been in use for over 40 years, and is cited in every computer network book. It is also a favorite resource for just about every cybersecurity exam. The OSI model is represented in seven layers that help us understand how communications between computer systems occur.
New research from the Cyentia Institute found that 98% of organizations do business with a third party that has suffered a breach. The report also found that the average firm has 11 third-party relationships and hundreds of indirect fourth- and nth-party relationships. Bottom line: an expanding attack surface makes companies more prone to cyberattacks.

Despite the popularity of the cloud, Microsoft Active Directory (AD) remains a crucial component of the IT infrastructure for many organizations. Indeed, Active Directory often serves as the central identity repository and provides vital authentication and authorization services — so keeping it clean and well organized is vital. Discover exactly why regular AD cleanup is critical — and the key signs of a poorly maintained AD environment.
If you are wondering whether your firm needs network detection and response (NDR), ask yourself this question: How often did your team come into the office in the last week? Probably more than they did last year, but almost certainly daily. This is what work now looks like for most people. And if this describes your organisation, you need an extra layer of defence inside your network perimeter. To see why, just look at what has happened to the network perimeter itself.
Research shows that most of today’s cyberattacks occur when a cybercriminal gains access to a system through stolen credentials. Users with extra privileges, particularly IT administrators, are often targeted by threat actors who steal those privileges to access sensitive information and take control of systems. With an increase in virtual and hybrid work, across both the public and private sectors, these kinds of attacks are only becoming more common.
Zero trust is a cybersecurity approach that restricts network access so only the right people are accessing the specific information they need —and nothing more. Here’s everything you need to know about the basic principles of Zero Trust and how to apply them to your third-party risk management program (TPRM) to create more secure remote access connections.
Security information and event management (SIEM) systems are crucial to cyber security, providing a solution for collecting and analyzing alerts from all manner of security tools, network infrastructure, and applications. But simply having a SIEM is not enough because to be truly effective, it must be properly configured, managed, and monitored 24x7.
