Memory scavenging
Memory scavenging: A technique used to identify and recover unused memory within a system. In terms of security, it’s crucial that once memory blocks are freed or repurposed, any sensitive data previously stored is properly sanitized to prevent information exposure to subsequent processes, effectively mitigating the risk of data leakage or exploitation.
Monitoring
Monitoring: The process of continuously collecting and analyzing data to identify potential security threats. It is used in IT security to identify and respond to potential security breaches in real-time. Examples include using network intrusion detection systems to monitor network traffic for anomalies and using security information and event management (SIEM) tools to collect and […]
Merkle Tree
Merkle Tree: A Merkle tree, named after Ralph Merkle, is a data structure in cryptography and computer science that consists of a hierarchical series of cryptographic hashes. Each non-leaf node is a hash of its respective children, and the hashes are organized into a binary tree. Merkle trees are used to efficiently and securely verify […]
Monolithic operating system architecture
Monolithic operating system architecture: A monolithic operating system architecture is one where the entire operating system, including the kernel, device drivers, and system services, operates in a single memory space. This traditional architecture can offer fast performance due to its direct access to system hardware, but it may be less flexible and more vulnerable to […]
Message Authentication Code (MAC)
Message Authentication Code (MAC): A short string of characters used to verify the integrity and authenticity of a message. It is generated by applying a cryptographic hash function to the message along with a secret key shared by the sender and receiver, ensuring the message’s integrity and authenticity during transmission.
Multipart Or Multipartite Viruses
Multipart Or Multipartite Viruses: A type of malware that can simultaneously infect both program files and system sectors, activating at every system startup. This dual infection approach makes it difficult to completely remove, as it can re-infect cleaned parts of the system.
