These cipher suites provide a set of algorithms and protocols that are required to secure communications between clients and servers. To initiate an HTTPS connection, the […]
What are Cybersecurity Metrics and KPIs? Cybersecurity metrics and Key Performance Indicators (KPIs) are crucial indicators that help security teams analyze how their security controls function over time. Cybersecurity KPIs and cybersecurity metrics are terms often used interchangeably, but there is a slight difference between their meanings- while cybersecurity metrics are quantifiable measurements pertaining to […]
What is Pretty Good Privacy Encryption? Pretty Good Privacy (PGP) is a security program used to decrypt and encrypt email and authenticate email messages through digital signatures and file encryption. PGP was one of the first public-key cryptography software applications that was publicly available, for free. Originally, it was used to enable individual users to […]
What is Platform Security Architecture? Platform Security Architecture (PSA) is a security certification scheme for Internet of Things (IoT) hardware, software, and devices. It was created by Arm Holdings, Brightsight, CAICT, Prove & Run, Riscure, TrustCB, and UL as part of a global partnership. Arm Holdings first brought forward the PSA specifications in 2017 to […]
