Encrypt All - See Nothing
Encryption is both a blessing and a curse for security, and the increase use of encrypted channels by malware highlights the downsides. As more and more of the internal and external IP traffic shifts to encrypted 443, the ability of traditional IDS/IPS and other related tools to see the traffic and spot malicious payloads is erased. With the drive by Google and others to drive all websites to HTTPS by marking HTTP websites as unsafe, before long encrypted traffic will be the expected norm. 

With this evolution, the ability to look at where traffic is going, rather than what it contains will increasiningly be used as a means to spot malicous traffic. Whether it is connections to known C&C systems or outbound connections to foreign countries at 2am when the company has no business connections there, security tools that leverage DNS as part of behavioural traffic analysis are the next wave in the fight against those who want to infiltrate and compromize corporate systems.
