How Real-Time Metadata Helps Detecting Attacks?

Meta DataMetadata offers more opportunities for organizations to store and analyze in real-time to discover the attacks.

Fremont, CA: Enterprises need the right tools to detect and identify critical security threats, tools for hunting, and performing diagnostics. However, searching for signs of an attacker is not an easy task. Rich metadata allows decoding and driving insights to find the attacker, halt the intrusion, and stop the attack. Rich metadata collected from a network can capture more than 90 percent of useful data that permits organizations to store and analyze in real-time to discover the attacks. There

 are many cost-effective ways of incorporating metadata that lowers the cost of storing the packet captures (PCAP) while giving the same level of visibility into the communication.

Metadata can be stored as flat text having the benefit of optimal compression rate for long term storage. It can also be stored in many standard formats like JSON or XML, rendering it searchable and reference-able by standard libraries. When it is a telephonic conversation, if the recording of communication is in the form of a searchable description, it could have the same value in a format much easier to consume. For example, extracting attributes from metadata that is close to near real-time as possible should be the new standard for cybersecurity. Security teams can investigate suspected incidents in a breeze with content-enriched metadata in near-real-time. This ability allows organizations to leverage metadata to detect multi-vector attacks by correlating related activities across multiple sessions. It gives investigating teams more significant insights into the stage of exploitation chain, type of malware downloaded so that organizations can take rapid and comprehensive remediation measures.

The rich metadata captures every session that the network sensor can encounter in the network enabling teams to investigate immediately. By placing sensors, server operation teams and incident response teams can gather information from all packets that move across a sensor. To gain more insights, enrich the metadata on tactics, techniques, and procedures (TTP). Enterprises can also apply new threat intelligence and indicators of compromise (IOC) to all metadata coming from network sensors, thereby determining threat through retrospective analyses. Thus, when enterprises do not utilize metadata, identifying risks will be a time-consuming process.
