As a cybersecurity and networking expert with extensive experience in securing enterprise environments, I’ve seen firsthand how cybercriminals evolve their tactics. Thwarting cybercriminals isn’t easy, but companies, governments, and organizations are taking proactive steps to limit and discourage these threats. In this article, we’ll explore key actions and measures, updated for 2025, with practical insights for enthusiasts looking to deepen their knowledge and implementation skills.
These efforts focus on collaboration, technology, and policy to stay ahead of attackers. While no single approach is foolproof, combining them creates a robust defense layered at the network level.
Early Warning Systems
They are creating early warning system sensors and alert systems. These systems can be costly, so it’s often impractical to monitor every network comprehensively. Organizations prioritize high-value targets, as these are more likely to face sophisticated cyberattacks.
Cyber early warning systems (CEWS) aim to detect attempts in their nascent stages. Designing and implementing such systems involves numerous research challenges, but they are essential for proactive defense.
The Honeynet Project is an international security research organization investigating the latest attacks, developing open-source security tools to improve Internet security, and studying hacker behavior. It serves as a prime example of an early warning system. The project also provides a HoneyMap, which displays attacks in real time. As of 2025, Honeynet is hosting its annual workshop in Prague from June 2nd to 4th and is applying to participate in Google Summer of Code (GSoC) for the 16th time, focusing on tool development.
AI-Enhanced Early Warning Systems
In 2025, early warning systems increasingly leverage AI for predictive analytics, spotting anomalies in network traffic before breaches escalate. Tools like Microsoft Digital Defense integrate AI to analyze threat data and disrupt attacks early. As a network engineer, I recommend configuring AI-driven Intrusion Detection Systems (IDS) like Snort or Suricata on perimeter routers. These can monitor for unusual patterns, such as sudden spikes in outbound traffic that might indicate data exfiltration. For enthusiasts, experiment with open-source AI models in tools like ELK Stack (Elasticsearch, Logstash, Kibana) to build custom anomaly detection on home labs.
Vulnerability Databases
They are establishing information security management standards for national and international organizations.
The National Common Vulnerabilities and Exposures (CVE) was developed as a national database to provide a publicly available list of all known vulnerabilities. CVE entries include an identification number, description, and at least one public reference for publicly known cybersecurity vulnerabilities.
2025 Updates to CVE and Network Integration
As of October 2025, CVE continues to catalog new vulnerabilities, with Microsoft’s October Patch Tuesday addressing over 167 flaws, including three zero-days such as CVE-2025-24990 and CVE-2025-59230. Network engineers should integrate CVE data into vulnerability scanners like Nessus or OpenVAS for automated network sweeps. For high-value targets, prioritize patching based on CISA’s Known Exploited Vulnerabilities Catalog. In practice, configure automated scripts on Cisco or Juniper routers to cross-reference CVE alerts with your ACLs (Access Control Lists) to block exploits in real-time.
Sharing Cyber Intelligence
Sharing cyber intelligence information between organizations and nations is crucial. Government agencies and countries now collaborate to exchange critical data about severe attacks, preventing similar incidents elsewhere. Several countries have established cyber intelligence agencies for worldwide cooperation, especially in major cyber attacks.
Sharing cyber information and intelligence is a vital technique to prevent hostile cyber-attacks. InfraGard is a partnership between the FBI and the private sector, exemplifying widespread cyber intelligence sharing.
2025 InfraGard Developments
InfraGard remains active in 2025, with key events including the RSA Conference (April 28-May 1 in San Francisco), where members receive discounts, and the Annual Member Meeting in Arizona on October 30. For network engineers, joining InfraGard grants access to threat intel that can inform firewall configurations, such as blocking malicious IPs shared via FBI partnerships. Enthusiasts can participate in webinars, like the June 3, 2025, program overview, to network and gain insights.
Information Security Management (ISM) Standards
The ISO/IEC 27000 standards are a prime example of information security management standards, also known as ISO 27000. These help organizations secure information assets like financial data, intellectual property, employee details, or third-party information. ISO/IEC 27001 is the best-known standard in the family, providing requirements for an Information Security Management System (ISMS).
Transition to ISO/IEC 27001:2022
Organizations must transition to the 2022 version by October 31, 2025, which includes new controls for cloud security and threat intelligence. As a network engineer, implement Annex A controls like 8.1 for secure network services by segmenting VLANs and adopting zero-trust models. This ensures compliance while enhancing resilience against evolving threats.
New Laws and Regulations
They are making new laws to discourage cyber attacks and data breaches, with strict penalties for caught cybercriminals.
ISACA, an independent, nonprofit global association (formerly the Information Systems Audit and Control Association), tracks cybersecurity laws and released its 2025 State of Cybersecurity report highlighting persistent staffing shortages and social engineering as the top attack vector (44% of respondents).
These laws address personal privacy and intellectual property protection, including the Cybersecurity Act, Data Breach Notification Act, Federal Exchange Data Accountability and Trust Act.
2025 Cybersecurity Legislation Updates
The Cybersecurity Information Sharing Act (CISA) expired on September 30, 2025, prompting shifts to new frameworks and increasing vulnerability concerns. Recent developments include the June 2025 Executive Order sustaining efforts to strengthen national cybersecurity, amending prior orders like 13694 and 14144. Network engineers should align with acts like NIS2 (EU) or CIRCIA (US) by enabling comprehensive logging on switches and routers for incident reporting. ISACA’s report emphasizes soft skills gaps, so consider certifications like CISM for team building.
Network-Level Best Practices for Thwarting Attacks
From a network engineer’s perspective, implement firewalls with deep packet inspection (e.g., Palo Alto or FortiGate) to scrutinize traffic. Use network segmentation via Software-Defined Networking (SDN) to isolate critical assets. Monitor with tools like Wireshark for anomalies, enforce strong passwords, and deploy multi-factor authentication (MFA) to counter credential stuffing. In 2025, integrate zero-trust architecture using tools like Cisco ISE for dynamic access controls.
Emerging Threats in 2025
The threat landscape is evolving rapidly. Ransomware attacks surged 46% in 2025, with 80% incorporating AI for sophistication, such as deepfakes in social engineering. CrowdStrike’s 2025 Global Threat Report highlights fast eCrime breakouts, increased China-nexus activity, AI in organized crime, and cloud intrusions. The World Economic Forum’s Global Cybersecurity Outlook notes cyber inequity, sophisticated threats, and AI as both threat and defense. Enthusiasts should prepare by simulating AI-driven attacks in virtual environments and adopting defenses like endpoint detection and response (EDR) tools
