Organizations want to stay on top of cyber threats and detect them even before they occur. To do this, they need to detect threats and anomalies in their networks as quickly as possible. This is what we call threat hunting<\/em><\/strong>. It is a tool to help organizations constantly monitor their networks to detect and mitigate threats to keep them at a distance.<\/p>\n

Today, proactive threat hunting<\/a> has become a necessary tool for modern enterprises to keep themselves protected against adversaries that might otherwise go unnoticed. Beyond this, threat hunting also helps them find malicious activities as well as identify activities that might not be malicious but can be a threat to their overall security posture.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Data in Threat Hunting<\/h2>\n<\/div>\n<\/div>\n
\n
\n

A significant part of the threat hunting<\/a> process is collecting and analyzing. It involves constantly analyzing data related to activities and movements in the network. This includes checking logs from servers, network devices, endpoints, and several other data points. Once this data is collected:<\/p>\n<\/div>\n<\/div>\n

\n
\n

\t\t\t\t\t\t\t\t\t\t1. The security team conducts thorough interpretation and analysis to determine forming patterns and trends.<\/span><\/p>\n

\t\t\t\t\t\t\t\t\t\t2. Using the data, they can find the ‘who’, ‘what’, ‘where’, ‘when’, and ‘why’ of any anomaly detected.<\/span><\/p>\n

\t\t\t\t\t\t\t\t\t\t3. This also helps them gain enhanced visibility of the network as well as remove any threat such as malware that has penetrated without raising any alarm.<\/span><\/p>\n

\t\t\t\t\t\t\t\t\t\t4. Significantly reduces the risk of a successful cyberattack.<\/span><\/p><\/div>\n<\/div>\n

\n
\n

While investigating data is important, enterprises also need metadata for proactive threat hunting. Metadata<\/a> can play a critical role in uncovering vital information about digital files. Metadata gives detailed insights that can change the way security teams investigate threats in their network.<\/p>\n

Metadata<\/strong>, also called data of the data, contains all the necessary information about the data that works as descriptors to the security teams. Metadata includes information, such as creation date, source, modification date, version, and other properties.<\/p>\n

Metadata analysis<\/strong><\/a> is all about uncovering and examining the hidden data related to digital files. It is a process of extracting metadata from various sources to reveal essential details about the files, such as creation dates, last accessed and modified dates, and other critical information. Analyzing metadata provides threat hunters with valuable insights that help in maintaining network security for enterprises.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Importance of Metadata in Threat Hunting<\/h2>\n<\/div>\n<\/div>\n
\n
\n

Security teams today can capture metadata about every data, document, and communication protocol in the network allowing them to start threat investigations quickly and understand the full implications of an attack. For example:<\/p>\n<\/div>\n<\/div>\n

\n
\n

\t\t\t\t\t\t\t\t\t\t\t
\n\t\t\t\t\t\t\t\t\t\t\t\t\t<\/span>
\n\t\t\t\t\t\t\t\t\t\tData from inside a web session can be collected, including the source and destination IP address. <\/span><\/p>\n

\t\t\t\t\t\t\t\t\t\t\t
\n\t\t\t\t\t\t\t\t\t\t\t\t\t<\/span>
\n\t\t\t\t\t\t\t\t\t\tData related to whether a document or executable has been transmitted before, the author of the documents, when the document was created, and information about tags and attachments. <\/span><\/p>\n

\t\t\t\t\t\t\t\t\t\t\t
\n\t\t\t\t\t\t\t\t\t\t\t\t\t<\/span>
\n\t\t\t\t\t\t\t\t\t\tThe ability to scrutinize common attacker tactics, such as SQL injection, web shells, content staging and cross-site scripting, regardless of whether malware has been used.<\/span><\/p><\/div>\n<\/div>\n

The absence of detailed metadata can leave security teams to rely on basic legacy rules. Here are the key ways metadata analysis can enhance threat hunting:<\/p>\n<\/div>\n<\/div>\n

Comprehensive data availability<\/h3>\n<\/div>\n<\/div>\n
\n
\n

Effective threat hunting depends on a huge amount of data in a specific environment. Hunters are required to gather about the surroundings and formulate theories on possible threats. Metadata becomes a great source of information for the hunters providing descriptive information about other data, helping to organize, find, and understand it. Types of metadata that hunters might use:<\/p>\n<\/div>\n<\/div>\n

Analyzing metadata for threat hunting creates an early warning system that is fast, informative, and affordable.<\/p>\n<\/div>\n<\/div>\n

\n
\n

\t\t\t\t\tFastMetadata analysis provides a searchable description of everything that is easier to consume and can be accessed in real time.InformativeMetadata contains all the necessary descriptors of the data itself allowing organizations to understand the past and present activities in the network.InformativeMetadata analysis is considered comparatively affordable to full data packet capture<\/a> systems as they create a huge amount of data which can skyrocket the storage fees.\t\t\t\t<\/p><\/div>\n<\/div>\n

\n

Enhance data integrity<\/h3>\n<\/div>\n<\/div>\n
\n
\n

Metadata plays an important role in maintaining quality and integrity of the data. It reveals crucial information about files to help security teams verify the accuracy and reliability of the information captured. It also provides a clear understanding of the data which can minimize the chances of errors due to misinterpretation. By analyzing metadata, threat hunters can investigate and verify whether files have been tampered with or not.<\/p>\n<\/div>\n<\/div>\n

\n
\n

Boost forensic investigation<\/h3>\n<\/div>\n<\/div>\n
\n
\n

Metadata caters to forensic investigations by providing valuable insights to security teams. The details may include timestamps, geolocation, file paths, and relationships between files, devices, and even individuals. Metadata can also help threat hunters to verify the authenticity of the digital documents or media files. For instance, if the metadata doesn\u2019t align with the file\u2019s purported origin, it can indicate file tampering or forgery.<\/p>\n<\/div>\n<\/div>\n

Key Types of Metadata<\/h3>\n<\/div>\n<\/div>\n
\n
\n

\t\t\t\t\t\t\t\t\t\tDescriptive Metadata: This type of metadata provides essential details about the content of a digital file. For example, title, author, and keywords.<\/span><\/p>\n

\t\t\t\t\t\t\t\t\t\tAdministrative Metadata: This type of metadata provides management details about a digital file. It covers information like file format, creation date, and access rights.<\/span><\/p>\n

\t\t\t\t\t\t\t\t\t\tStructural Metadata: This type of metadata indicates how different parts of a resource are organized, formatted, and related.<\/span><\/p><\/div>\n<\/div>\n<\/div>\n
