Understanding linear algebra provides cybersecurity experts with a solid foundation in the principles of applied mathematics, computer science, and information systems. It speeds up machine learning and makes faster information retrieval possible. Linear algebra is used to design and build many computer systems, including graph visualizations, images, cryptography, and image processing. In cybersecurity careers, these computations revolve around algorithms used by hackers to solve these complex equations and those used by cybersecurity experts to preserve information security. The harder a computation is to perform, the better protected a particular bit of information is. These programs use algorithms designed around the computational hardness assumption, a computational complexity theory that finds difficult-to-solve problems and applies them to sensitive data. CryptographyĬryptography uses mathematical theories to provide data confidentiality. It's used most often in computer memory addresses such as IP addresses. Hexadecimal math provides a more human-friendly expression of binary values. Number strings are represented as single-digit numbers up to 9 and then letters A-F for the remaining placements. Hexadecimal math expands the options from 0 or 1 to any digit up to 16 places (0-15). Therefore, knowledge and comfort with Boolean algebra concepts can provide a good foundation. Python is a favorite language among hacking (and ethical hacking) and cybersecurity communities. This branch of Algebra incorporates the binary values of 0 and 1, and several modern programming languages like Python use this mathematic system to express decisions and responses. Leveraged in modern computer programming, Boolean math expresses information in a series of "false" and "true" values. An understanding of binary math helps cybersecurity analysts understand and create the unique programs that keep networks safe and facilitates understanding weaknesses in existing code. This binary math is the heart of all computer programming. Data is stored in strings called bytes or unique combinations of these bits. The smallest layer of information in computer programming is known as a "bit," equal to a 0 or 1. Binary mathīinary math is the language of computer systems. So what kind of math prepares you for a career in cybersecurity? There are a few different things you'll need to know. However, moving into a bachelor's degree would necessitate training in cybersecurity mathematics and programming math. What kind of math is used in cybersecurity?Īssociate degrees may not require much math beyond high school-level math. In cybersecurity, you'd translate this thought process into a specific equation to visualize the risk threat. For example, in calculating risk, you might think to yourself, "what is the probability that I'll encounter a worst-case scenario" and then draw on all your previous experiences plus your knowledge of the situation. You probably use this type of math every day already and don't realize it. Once you learn the "language" of math, you're better equipped to translate real-world challenges into something that a computer can understand and analyze. It's a key to speaking directly to information systems. Math is a language used to express natural occurrences like probability and risk. However, beyond entry-level jobs, cybersecurity experts and analysts need to get comfortable with the idea of using some mathematics. It isn't a math-intensive field-not like astrophysics or engineering-but it requires comfort using certain math types. Does cybersecurity involve math?Ĭybersecurity is a technical field in computer science, and potential job seekers will need strong analytical skills. Doesn't cybersecurity involve complex math? And more importantly, what kind of math and where do I learn it? Let's take a look at the math you'll need to know to break into cybersecurity and how to prepare for a career in the field. As new types of threats loom over businesses and government entities, they'll look to hire the next generation of cybersecurity experts. According to the Bureau of Labor Statistics, the information security field will grow much faster than average-33% over the next ten years compared to the general average of 8%.
