How Log Monitoring Helps Cyber Security?

Logs have been important actors of cyber security environments for a while now. In this article, we will take a closer look on log monitoring and how it can help cyber security operations of your business.

Whichever industry your business operates in, your teams and operations rely on information technologies in order to be more productive. It is no secret that a single computer or a similar device contains sensitive information that can cover thousands of pages in paper. On a daily basis, gigabytes, maybe even terabytes of such information regarding your business and operations travel at least tens of computing devices. During this fast and dangerous journey, the data is exposed to cyber attacks because of the numerous vulnerable features of the stops it makes along the way. That is why, regardless of the size of your business operations, your systems must always have strong and up to date security measures.

Most of the time, the sensitive information kept inside is way more valuable than the hardware itself. Thus many attacks and thieves focus on the data instead of hefty and difficult to carry hardware. An attacker can opt for various strategies such as identity theft, log forging, malware, and social engineering. Therefore, keeping the networks and systems of your business is an ongoing task that keeps evolving and your IT security team needs the best tools to do their job properly. In this challenging journey, monitoring and log data are very prominent tools.
