In the field of cybersecurity, there is a significant gap between security researchers and software engineers, which can hinder effective
security practices. LauriWired discusses the importance of programming knowledge for security researchers, emphasizing that understanding
software engineering is crucial for various aspects of cybersecurity work.
Reverse engineering is a key area where programming knowledge is essential. When examining a new binary in an unfamiliar language,
understanding the original language’s structure and nuances can make reverse engineering more manageable. For instance, knowing Objective C’s
method invocation and selector names helps in visualizing the source code, making decompilation less daunting.
Security tools, often developed by others, are widely used in cybersecurity. However, when these tools fail or need customization,
having programming skills allows researchers to fix or enhance them independently. This capability extends to creating entirely new tools
that may not yet exist, leveraging unique insights from both development and security perspectives.
Exploit development and vulnerability research also benefit from programming expertise. Manual code audits require a deep understanding
of the code, often surpassing the original developer’s knowledge. This dual perspective helps identify exploitable vulnerabilities that
developers might overlook. Additionally, creating custom fuzzers to target specific code sections or developing proofs of concept (POCs) for
exploits necessitates strong programming foundations.
Big data analysis is another critical aspect of cybersecurity. Security analysts must navigate various databases and automate their
analysis to track threats effectively. Programming skills enable them to write scripts that sift through data, identifying relevant information
to share with the community.
Cryptography, a complex topic within cybersecurity, also requires
programming knowledge. Understanding cryptographic algorithms and being
able to write cryptographic functions aids in reverse engineering
ransomware and finding potential backdoors. Recognizing common mistakes
in malware authors’ code can lead to exploiting these errors for
defensive purposes.
Creating detection rules, such as Yara rules for identifying malware
samples, benefits from knowing what constitutes common versus unique
code in binaries. This knowledge helps in crafting effective rules that
capture all related malware samples, preemptively thwarting malware
authors’ efforts.
Bridging the gap between developers and security researchers is
crucial for effective communication and collaboration. Understanding
both perspectives allows security researchers to convey the importance
of addressing vulnerabilities while acknowledging developers’
constraints and priorities. This mutual understanding fosters a safer
application environment and a more cohesive working relationship.
Overall, LaurieWired argues that programming knowledge is
indispensable for security researchers. It enhances their ability to
reverse engineer, develop tools, analyze big data, understand
cryptography, and create detection rules. By mastering software
engineering concepts, security researchers can significantly advance
their capabilities and contribute more effectively to the cybersecurity
field.
