Introduction In modern cybersecurity, preventative security measures such as authentication, access control, and security policies aim to protect systems from attacks. However, when an attack bypasses these defenses, intrusion detection and prevention systems (IDS and IPS) become critical for identifying…

Cryptography plays a critical role in securing federal systems, sensitive data, and communication channels. To ensure uniform security, government agencies must adhere to strict cryptographic standards set by organizations like NIST (National Institute of Standards and Technology) and OWASP (Open…

Cryptography is essential for securing modern digital communications, protecting sensitive data, and ensuring user authentication. However, poor implementation of cryptographic techniques can introduce severe vulnerabilities, making even the strongest encryption algorithms ineffective. This guide explores common pitfalls in cryptographic implementation,…

Cryptographic hash functions play a vital role in data integrity, authentication, and digital signatures. However, weak hash functions like MD5 and SHA-1 are vulnerable to various cryptanalytic attacks, compromising the security of digital systems. This guide explores how hash functions…

Cryptography is the backbone of modern cybersecurity, ensuring secure communication, data protection, and digital identity verification. This guide, based on key topics from Serious Cryptography by Aumasson (2017) and Understanding Cryptography by Paar & Pelzl (2010), provides insights into advanced…
