New cybersecurity advisory highlights defense-in-depth strategies
- CISA has released its SILENTSHIELD assessment report detailing red-team findings after a breach of an FCEB organization, which has a renewed focus on defense-in-depth strategies.
- The red team was successful in lateral movement and persistence through exploiting trust relationships and deploying defense evasion techniques.
- CISA shared four key findings with the FCEB organization after the collaboration phase, including: insufficient controls, failure to effectively collect and analyze network logs, poor communication between network defenders due to decentralized structure, and failed breach detection of new threat actors.
- CISA recommends that businesses use defense-in-depth principles, apply robust network segmentation, establish baselines of network traffic, application execution, and account authentication, and make sure their business is prepared for a cyber breach.
- Organizations need to adopt a more holistic strategy for cybersecurity, including firewalls, intrusion detection and prevention systems, and antivirus and antimalware tools.
- Benchmarking current network traffic patterns can provide an easier recognition of anomalies that could point to malicious activities, allowing for the response teams to address threats before they become significant issues.
- IBM X-Force Cyber Range can help organizations better prepare their defenses by providing immersive simulations.
- Proactive planning can significantly benefit IT teams, ensuring their security protocols are hardened and ready to face modern cyber threats.
- CISA’s recent assessment is an example of the importance of effective security and breached preparedness planning.
- IBM X-Force Cyber Range can provide the tools and techniques businesses need to keep their organization secure.
