2020 was brutal for a wide range of enterprises, as all industries observed. It became very clear that even the most powerful and prestigious businesses and organizations are vulnerable to sophisticated cyber-attacks. This means that security experts should adopt a proactive approach rather than a reactive one.
But how can firms prepare for the unexpected? Many security experts would be perplexed. It all starts with increased visibility across the enterprise and the implementation of proactive threat hunting methods.
Here are four essential proactive threat hunting success aspects that firms must follow.

Every new generation of security technology can detect a greater number of complex threats, but the human brain remains the most effective detection engine. Automated detection approaches are fundamentally predictable, which attackers are well aware of and have developed strategies to circumvent, avoid, or effectively hide from. Human threat hunters are an essential part of any successful threat hunting service.
Since proactive hunting relies on human contact and involvement, who is hunting through the data determines success. Intrusion researchers must have the knowledge and resources to detect sophisticated targeted assaults, as well as the security resources to deal with any anomalous activity discovered.
Since threat hunters must gather, combine, and evaluate a large quantity of data, automation is a crucial tool. To speed up and simplify the process, threat hunters might employ a variety of specialized threat hunting platforms and tools. Automation can aid in the development of hypotheses and the focusing of danger hunters’ attention in addition to data collecting. Artificial intelligence (AI) and user and entity behavior analytics (UEBA), for example, can assist in recognizing unusual occurrences that require further examination.
Threat intelligence, which may be separated into indicators of compromise (IoC) and indicators of attack (IoA), is referred to as intelligence. For IoC, it’s similar to an antivirus signature, or the fingerprints of previous assaults-for example, a public IP address, a domain name, and the checksum value of a file. For IoA, it’s more about taking a strategic view on known threat actors’ or groups’ tactics, techniques and procedures (TTPs). The MITRE ATT&CK knowledge base and matrix is one of the greatest sources of IoA since it depicts all known real-world attack TTPs and offers threat hunters with a well-informed hypothesis to perform proactive threat hunting with directives.

SOC teams must be aware of every conceivable vulnerability in their system in order to anticipate the unforeseen and keep one step ahead of cybercriminals. Furthermore, as enterprises become more networked as a result of the installation of numerous IoT devices, security experts need to get their A-game if they are to avoid attacks.
Furthermore, as a result of the COVID-19 pandemic, more employees are relying on their vulnerable personal networks rather than their far more secure business networks.
Unfortunately, as networks get more sophisticated, the visibility of SOC teams goes down, enabling hackers to sneak in and compromise systems unnoticed. This is why, in order to assure optimum security, visibility-enhancing technologies must be used to rapidly offer much-needed security visibility throughout all endpoints.
