What Should A Modern Cybersecurity Stack Look Like?
A modern cybersecurity stack requires a layered approach encompassing technologies, processes, and skilled personnel to effectively defend against contemporary threats like ransomware, phishing, and identity-based attacks. It’s more than just a firewall and antivirus; it’s a balanced system covering prevention, detection, response, and recovery across endpoints, identities, networks, and cloud environments. Strong security hygiene forms the foundation, making an organization a more difficult target. This includes asset management, automated patch management, and configuration hardening.
Endpoint security and detection are critical, with next-generation antivirus (NGAV) employing AI and machine learning to combat malware and fileless attacks. Endpoint detection and response (EDR) provides deep visibility into endpoint activity, enabling investigation and response to threats that bypass initial preventive measures. Identity and access protection is non-negotiable, prioritizing multi-factor authentication (MFA) everywhere possible and privileged access management (PAM) to control privileged accounts. Cloud and SaaS security must extend to platforms like Microsoft 365, demanding dedicated tools like cloud access security brokers (CASB) and SaaS backup solutions.
Network and email security remain essential, featuring next-generation firewalls (NGFW) with intrusion prevention systems (IPS) and application control, secure email gateways to filter malicious content, and DNS filtering to block access to malicious websites. Continuous monitoring, automation, and rapid response are vital, utilizing security information and event management (SIEM) to centralize log data and managed detection and response (MDR) for 24/7 expert threat monitoring and response. Backup, recovery, and business continuity plans must include immutable backups and a tested disaster recovery (DR) plan.
Governance, risk, and compliance (GRC) provide the overarching framework, ensuring security efforts align with business objectives and regulations. This includes security awareness training for employees and regular risk assessments. Evaluating tools for inclusion in the stack requires considering their proactive capabilities, robust intelligence, scalability, and interoperability. Regular testing and validation through penetration testing, breach simulations, and audits are essential to ensure the cybersecurity stack works effectively in the event of a breach. Frameworks such as MITRE ATT&CK can help identify gaps and assess the effectiveness of specific tools.
