DKIM is an email authentication method that allows the recipient to verify that an email was not altered during transit and that it was sent by an authorized sender for a particular domain. This helps protect against email spoofing and ensures email integrity. How DKIM Works: DKIM Signature Example: A DKIM-Signature header in an email… Read more

DMARC is an email authentication protocol that builds on SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) to help domain owners protect their email domains from unauthorized use, such as phishing and spoofing attacks. DMARC also provides reporting capabilities, enabling domain owners to monitor and enforce email authentication policies. How DMARC Works: DMARC Record… Read more

Endpoint Detection and Response (EDR) is a cybersecurity technology that continuously monitors endpoints (like laptops, desktops, and mobile devices) to detect and respond to cyber threats like ransomware and malware.   Here’s a breakdown: In simpler terms: Imagine EDR as a highly sophisticated security guard for your devices. It constantly monitors for suspicious activity, alerts you… Read more

HMAC (Hash-based Message Authentication Code) is a specific type of message authentication code (MAC) that uses a cryptographic hash function in combination with a secret cryptographic key. It’s crucial for ensuring both the integrity and authenticity of messages in cybersecurity. Here’s a summary of HMAC in a cybersecurity context: Core Function: Key Security Properties: How… Read more

HTTP stands for Hypertext Transfer Protocol. It is a protocol used for transmitting data over the web. Specifically, it governs how web browsers (clients) and web servers communicate with each other to exchange resources, such as HTML documents, images, videos, and other web content. HTTP is foundational to the World Wide Web and is responsible… Read more

IDPR stands for Intrusion Detection and Prevention Response. In essence, IDPR represents a comprehensive approach to cybersecurity that encompasses the entire lifecycle of an attack, from detection and prevention to response and recovery. Note: The terms “Intrusion Detection System (IDS)” and “Intrusion Prevention System (IPS)” are often used interchangeably, and IDPR encompasses both detection and… Read more

Indicator of Compromise (IOC) is a piece of digital forensics that suggests that an endpoint or network may have been breached.   Think of them as the “breadcrumbs” left by an attacker. These clues help information security professionals identify malicious activity or security threats, such as data breaches, insider threats, or malware attacks.   Here’s a breakdown:… Read more
