Before the era of UTM (Unified Threat Management or next-generation firewall), we most often dealt with stateful firewall devices. The principle of operation of the stateful firewall is primarily operating on the headers of the third network layer (L3) and the fourth transport layer (L4) of the OSI model. Thanks to the understanding of headers […]

According to Verizon in their 2022 report, over 82% of security incidents were related to human-side negligence, such as password leaks or phishing. Moreover, passwords being stolen have various lengths and degrees of complexity. Considering the scale and improvements in methods used by malicious actors, it’s not that difficult to see even a strong password […]

Why is it important to take a comprehensive approach to secure Internet interfaces, instead of focusing on one area, e.g. a firewall?   In this article, we will take a shot at answering this question, showing potential Internet interfaces that can be critical in case of attack. You will learn what firewall network security is and […]

When dealing with networks, both wired and wireless, we can’t fail to mention the security issue. In the case of wireless networks, many users are unaware of the hazards lurking when switching between networks and using unprotected, unverified wireless networks. This article will answer your questions on securing the Wi-Fi network and making it resistant […]

To check whether a given IT infrastructure is resilient, and its LAN security strong, first, we need to run audits and penetration tests. While performing these, we use various protection breaching techniques to access the company’s resources. One of the basic tests is an attempt to obtain as much information as possible at a local […]

In today’s post, we’ll cover the planning, design, and building of professional, Enterprise-grade wireless networks, i.e. advanced wireless networks. We’ll touch on the selection of equipment and components used in these professional networks. We’ll also review Wi-Fi access network protections in tandem with a component called Cisco ISE, which plays a role of a hub for […]

Cisco ISE is a solution designed for controlling the secure network access policy and thus, the organization’s critical resources. It’s a single point providing information on events related to the connection of devices and users to the network.  ISE is much more than a concept of complementary security and an “intuitive” network, but we’ll get […]

Spectacular bank robberies with a gun in hand and a stocking on the face are history. Modern criminals moving into cyberspace use much more sophisticated ways to make a profit.
