Whether you are a DevSecOps engineer responsible for managing your organization’s application infrastructure or you have your own personal Linux server that you use at home, the importance of keeping your systems safe and secure against malicious attacks by bad actors cannot be over emphasized.
Many of the kernel bugs present in the Linux system are potential security flaws. Hackers use the vulnerabilities inherent in the Linux kernel to gain privilege escalation or to create denial-of-service attack vectors.
Open Source is currently being recognized by more organizations than ever before for its ability to give rise to flexible, cost-effective and exceptionally secure software and technologies. Over 75% of organizations worldwide are now contributing to and consuming open-source software and products.

Threat intelligence (or threat intell) is information used to understand past, present, and future threats targeting an organization. It is evidence-based knowledge about a previous, existing or emerging threat to organizational assets. Threat intelligence also includes settings, implications, mechanisms, context, and even action-oriented advice on the threat. Context mentioned here includes who the attackers are, what their motivation is, what their capabilities are, and what indicators of compromise are in your system. An Indicator of compromise (IOC) is forensic data in a system log file, for example, which identifies malicious activities on a system or network.

Operational security at least seemed so much easier back when traditional 9-to-5 office life was still dominant. Talk of professionals taking their work home with them was largely metaphorical, with only occasional instances of C-suite types dragging their laptops everywhere they went. Business hardware and systems would be shielded through physical security and isolated networks. One office (or office complex), one place to guard: entirely straightforward.
