Summary
At the start of this chapter, we mentioned the pivotal role of DNS as one of the most crucial protocols in the realm of cybersecurity. The significance of DNS security extends beyond endpoint protection, making it a paramount topic in the broader landscape of cybersecurity. Our journey commenced with a granular exploration of DNS packets, unraveling the intricacies of how the DNS system operates. We delved into the rationale behind companies segregating local DNS and forwarding DNS services.
Expanding our understanding, we delved into the limitations of relying solely on DNS logs and explored the need to enhance their utility. Additionally, we explored the intricacies of enriching DNS logs to bolster their effectiveness in detecting and thwarting malicious activities. Among the nefarious activities we dissected in detail were requests for domains without IP addresses and the insidious practice of DNS tunneling.
As we transition to the next chapter, our focus will shift...
