Encryption has been an integral part of human communication for centuries, with its importance growing exponentially in the digital age. From the earliest ciphers used to protect military communications to the encryption standards securing sensitive data today, encryption has always been critical for ensuring privacy and confidentiality. In modern IT infrastructures, encryption is a fundamental tool in safeguarding online communication and protecting sensitive information. There are two primary types of encryption techniques used today: symmetric encryption and asymmetric encryption. Both of these encryption methods play crucial roles in modern cybersecurity,…

When a security incident occurs, it serves as an invaluable opportunity for organizations to learn, grow, and improve. A well-executed post-mortem analysis enables businesses to identify what went wrong, understand the factors that contributed to the issue, and determine the measures that need to be taken to prevent similar incidents in the future. Conducting an effective post-mortem is essential for building stronger defenses, enhancing security posture, and ensuring that organizations are better prepared for future threats. The Purpose of an Incident Post-Mortem An incident post-mortem is not about assigning blame…
