Cyberthreats have been coming at us from the left, right, and center. The number of cyberattacks is forever on the rise, and companies need to keep ramping up their security measures to protect themselves. It’s important that these measures cover every aspect of a network environment. To understand why monitoring your whole environment is so important, let’s take a look at what an attacker might do once they get inside your organization.
Let’s say that an attacker named Breacher got access to a user account through a phishing email. Now, it’s unlikely that Breacher will use that one account to perform all their malicious activities. It’s too easy to get caught this way. So Breacher will try to gain access to another account or a computer connected to the network, and laterally hop on to that account using a technique known as island hopping.
This means that anomalous activities carried out by Breacher will not be observable from a single user account; instead, they will emanate from different accounts that Breacher keeps switching between. Once Breacher gets access to the administrator account, it’s game over. In such a scenario, it’s difficult to pinpoint the exact location in the network from where Breacher is operating. By the time this mystery is solved, the attacker will have moved five steps further ahead. This is part of why it can take days or even months to detect a breach.
Check out our e-book explaining four key cybersecurity monitoring pillars crucial in detecting and defending against cyberattacks before they cause harm.
Leveraging event correlation while monitoring your environment can go a long way in identifying anomalous activities and mitigating threats easily. This is why having a bird’s-eye view of your environment is the first of the four key cybersecurity monitoring pillars. These four pillars are:
A bird’s-eye view of your environment
Defense systems monitoring
Safety mechanisms for outside threats
Insider threat detection
To help you understand more about what these pillars encompass, we’ve drafted an e-book that explains these four pillars, and how you can implement them in your organization using a comprehensive SIEM solution. Check out our e-book, and learn how you can ensure that your organization is secured no matter how an attacker tries to get inside.
