Binary format
(also Base-2 format)
Binary format definition
The binary format is a way of representing data using only two digits, usually 0 and 1. Each digit in the binary format represents a power of 2. The rightmost bit represents 2^0 (1), the next bit to the left represents 2^1 (2), the next bit 2^2 (4), etc. Combining these bits enables representing all kinds of data types, including images, audio, video, and text. While it may not be human-readable, it sets the base for many important computing technologies, such as digital circuits, data storage, and communications protocols. Moreover, understanding binary format can help users address and avoid vulnerabilities that hackers tend to exploit. Experts utilize various tools to analyze binary files and codes for potential security risks.

Securing binary format
- Access control system. Restricting access to binary code is crucial if organizations want to mitigate unauthorized access and other malicious activities.
- Secure code development. This method prevents the appearance of vulnerabilities during the development process. It involves validating input, reviewing the code, and conducting safe coding practices.
- Binary analysis. By utilizing tools and manual analysis methods, experts can detect potential vulnerabilities and remove them before hackers use them to cause data leaks.
- Encryption. Users can access encrypted binary data using only a unique key that secures it against unauthorized access.
- Code signing. Developers can sign their code with a unique digital signature that guarantees the safety of the code and reduces malware attacks.
- Patch management. This technique applies regular software updates that come with security patches. As a result, hackers won’t be able to exploit the vulnerabilities in the binary code, causing a decrease in cyberattacks.
