    IPSec The Hidden Security Layer of the Internet

    Before IPSec, the internet operated like an open street with no surveillance every packet was visible, traceable, and easy to manipulate. Data moved fast, but it moved naked. Anyone sitting in the right place on the network path could observe, replay, or tamper with traffic. IPSec was created to fix this fundamental flaw at…

  • Hidden Protocols in Networks: Beyond TCP/IP

    Hidden Protocols in Networks: Beyond TCP/IP

    Modern network security is still heavily shaped by assumptions made decades ago: traffic flows over well-known ports, protocols are explicit, and malicious behavior is noisy. Advanced attackers exploit exactly these assumptions. By using hidden or lesser-known protocol techniques, they turn the network into a gray zone where traditional visibility breaks down. The Illusion of…

  • When Silence Becomes a Signal: Attacks Emerging From Network Quiet Zones

    When Silence Becomes a Signal: Attacks Emerging From Network Quiet Zones

    Advanced intrusions rarely announce themselves. In fact, some of the most dangerous breaches begin with the opposite: a sudden absence of the traffic patterns you expect. Modern networks create predictable rhythms ARP chatter, DNS lookups, routine broadcast noise, service heartbeats. When those patterns collapse, the silence isn’t calm; it’s a warning. 1. The Hidden…

  • Advanced Persistent Threats (APT) on Mobile and Network Systems

    Advanced Persistent Threats (APT) on Mobile and Network Systems

    Advanced Persistent Threats (APTs) represent the highest tier of targeted cyberattacks: long-term, strategic intrusions executed by highly skilled adversaries, often state-sponsored groups or well-funded criminal organizations. Their goal is simple: remain inside a system for as long as possible while silently gathering intelligence, manipulating assets, or preparing for strategic disruption. Unlike common malware or…

    Advanced Persistent Threats (APTs) on Mobile Devices and Enterprise Networks

    Advanced Persistent Threats (APTs) are not ordinary cyberattacks. They are long-term, highly coordinated intrusion campaigns typically executed by well-resourced groups with strategic goals. These groups often include state-sponsored units, cyber mercenaries, or organized criminal operations. Their objective is not quick profit or temporary disruption; their goal is ongoing access, intelligence gathering, and silent control.…
