Key Points:
- Active adversaries are constantly evolving their attack tactics, requiring organizations to have dynamic defenses that can adapt.
- Threat intelligence is crucial to proactively identify, prevent, and respond to cyber-attacks.
In the article “Fighting active adversaries: The need for dynamic defenses,” George V. Hulme discusses the importance of organizations having dynamic defenses to combat the ever-evolving tactics of active adversaries. As attackers become more agile in their techniques, enterprises need security policies that can adjust and adapt in real-time. This requires a governance policy that re-evaluates risk constantly and security processes that can change based on new threat contexts and attack methods.
Hulme emphasizes the role of threat intelligence in keeping security defenses dynamic. Threat intelligence provides valuable insights and context that help organizations anticipate, prevent, and respond to cyber threats. By proactively collecting and utilizing threat intelligence gathered from various sources such as security logs, open-source intelligence, and threat intelligence feeds, organizations can stay ahead of potential threats.
To effectively gain the necessary insights to update security policies as threats evolve, organizations should consider steps such as creating a threat intelligence program, outsourcing for intelligence gathering and analysis, and harnessing quality and relevant threat intelligence sources. It is also essential to analyze threat intelligence data to prioritize and adapt security measures accordingly.
Moreover, Hulme highlights the importance of keeping security policies and defenses up to date, updating web applications, network firewalls, intrusion detection/prevention systems, and incident response playbooks as needed. He also recommends having network and endpoint security toolsets that can adapt quickly to changing threats.
Overall, organizations must be proactive in their approach to cybersecurity, utilizing threat intelligence, dynamic defenses, and adaptive security policies to protect against active adversaries who are constantly evolving their attack strategies.
