It’s been a long time since I audited someone’s DNS file but recently while checking a client’s DNS configuration I was surprised that the CAA records were set randomly “so to speak”. I discussed with the administrator and was surprised to see that he has no clue of CAA, how it works and why is it so important to enable it correctly. That made me wonder, how many of us actually know that; and how can it be a savior if someone attempts to get SSL certificate for your domain.
There has been a lot of buzz about the relationship between Security and DevOps as if we are debating their happy companionship. To me they are soulmates, and DevSecOps is a workable, scalable, and quantifiable fact unlike the big button if applied wisely. What is DevOps? The development cycle has undergone considerable changes in last few years. Customers and clients have evolving requirements and the market demands speed, and quality. The relationship between developers and operations have grown much closer to address this change.
The threat landscape is very dynamic, and new threat vectors are exploiting vulnerabilities for fun and profit. The whitehat security community is having a race against time with their counterparts. And, often the companies are becoming a target to spear phishing, APT and bots. Some institutions like financial sector, insurance sector, defense etc. have strong regulations to protect the perimeter. But, often these sectors have people working on their modern laptops with different adaptors - Wifi and Bluetooth.
Vulnerabilities are increasing by leaps and bounds and any industry – technical or non-technical has to grow its security in sync or else, it is highly vulnerable and lucrative target. There is news of data loss, breaches every now and then. A rough estimate of the growth of vulnerabilities (as reported) over last decade (1995-2008) is shown in Figure 1. This accounts to vulnerabilities as reported, wherein there are hundreds of active (non-reported or un-patched) vulnerabilities floating underground which are in the hands of money driven and black hat profit driven attackers.
