Threat Hunting service in dubai

Cyber Threat Hunting is an active cyber defence activity. It is "the process of proactively and iteratively searching through networks to detect and isolate advanced threats that evade existing security solutions.

After sneaking in, an attacker can stealthily remain in the network for months as they silently gather data, search for confidential material, or gain login credentials with which they can move laterally across the environment.

Once the detection is evaded successfully by an adversary who penetrates the organisation's defence through persistent attacks, many enterprises lack the next generation detection capabilities needed to stop APT’s from remaining in the network. This is what makes Cyber Threat Hunting an essential component of any defence strategy.

What Tools Does a Threat Hunter Need?

A hunter with intel on a new attack may be able to quickly spot IOCs (Indicators of Compromise) or IOAs (Indicators of Attacks) within a network and act on this information. Some essential items include:

  • Data: A hunter will need access to the logs of any meaningful device on your network: this includes servers, network devices (i.e. firewalls, switches, routers), databases, and endpoints. If this sounds like a lot of data, that’s because it is! A very important point is having a centralized location to assemble this data for analysis, including critical steps such as data collection, correlation, and normalization from the several different data points we just mentioned. In this case, a good SIEM solution is a hunter’s best friend.
  • Baselines: If the hunter is supposed to detect abnormalities, having a baseline of the network’s traffic behaviour can be of immense value. In broader terms, a baseline will define what events are expected and authorised, making it easier to spot anomalies that must be investigated.
  • Threat Intelligence: It is not unusual for cybercriminals to cooperate with each other, sharing information, codes, and malicious artifacts. As more and more attacks with similar techniques occur, it increases the chance of a group or company having spotted it before. Threat Intelligence (also commonly referred to as Cyber Threat Intelligence) is the process of acquiring, through multiple sources, actionable knowledge about threats to an environment.
