The climb is getting steeper, but thanks to hard work, vision and insight are much keener. At ML:4, all assets are scanned by a combination of agent and remote scans on a normal cadence. This will generate a lot of data dictated by threat and patch priority. Thousands of new vulnerabilities are released each year, and no company or product can...

Not all attackers are trying to exfiltrate data. In security, we’re all familiar with CIA triad—confidentiality, availability, and integrity. While Exfiltration describes adversarial behavior with the goal of violating confidentiality, attackers may look to manipulate, interrupt, or destroy your systems and data.

One thing I have noticed is that each industry comes up with their own terms and acronyms. Unfortunately, these inventions often vary depending on the person you speak to due to a lack of a governing body that decides on an exact definition.

For the majority of people in the information security world, the act of offensive hacking is something they are tasked with protecting against but have little ability to do themselves. That is like asking a professional boxer to enter the ring without knowing how to throw a punch. Sure, you may be able to get in and last a few rounds, but...

Zero Trust is a security concept that is based on the notion that organizations should not take trust for granted, regardless of whether access attempts originate from inside or outside its perimeters. An enterprise needs to verify any attempt for connection to its systems before granting access. At the same time, the defensive layers that define...

How Is YARA used? Historically, common detection methods have used file hashes (MD5, SHA1, and SHA256)—unique signatures based on the entire contents of the file—to identify malware. Modern threat actors have increased in sophistication to a point where every instance of a given malware will have a different hash, and that hash will vary from...
