What is Homomorphic Encryption? Homomorphic encryption allows performing computations on data without having to decrypt it first. Confidentiality is maintained, and at the same time, the calculations yield the same results as if they had been performed with unencrypted data. The results are encrypted and can be viewed with knowledge of the appropriate key. Fully … Read more
What is a Hashmap? A hashmap is a data table with a special index structure that allows fast retrieval of data objects. The position of a data object is defined by a hash function. In the hashmap, the data is stored as key-value pairs. The values can be retrieved via the key. The time required … Read more
What is CWE (Common Weakness Enumeration)? Common Weakness Enumeration is a freely accessible list of typical vulnerabilities in software and hardware. It categorizes vulnerabilities and serves as a basis and common language for identifying security-related weaknesses. The list is maintained by the community and published by the MITRE Corporation.

Looking hard for secret tips on website maintenance? Without question, websites now serve as the primary norms of communication between businesses and their customers. It is true, as they say, “First impressions are lasting impressions.” Undoubtedly, you must invest money in a decent website for your business, but creating one is only the first step. … Read more
What is A Man-In-The-Middle Attack? In a man-in-the-middle attack, the attacker places himself logically or physically between the victim and the resources used. He is thus able to intercept, read or manipulate the communication. End-to-end encryption is an effective countermeasure against a man-in-the-middle attack. What Is a Man-In-The-Middle Attack? A Man-in-the-Middle (MITM) attack is a … Read more
What is a Pass-The-Hash Attack? Pass-the-Hash is an attack method that uses the hash value of a password to authenticate against a system. Through vulnerabilities in the system or in the authentication protocols, the hash value can be read out with tools and used for authentication. The attack method can be used in various operating … Read more
What is Key Management? Key management manages the keys needed for cryptographic procedures. They can be symmetric or asymmetric keys. The tasks of key management include the generation, storage, exchange, and protection of keys. What is Key Management? Key management is a crucial aspect of modern information security. It involves the generation, storage, distribution, and … Read more
What is OAuth (Open Authorization)? OAuth is an open security protocol for token-based authorization and authentication on the Internet. Third-party web services can access external resources without disclosing usernames and passwords. Services from Google, Facebook, or Twitter use OAuth. What is OAuth? OAuth, which stands for “Open Authorization,” is a widely adopted authentication and authorization … Read more
What is A Buffer Overflow? Buffer overflow is a frequently occurring and frequently exploited security vulnerability. A buffer overflow occurs when it is possible to write more data to memory than the designated buffer can hold. This causes adjacent memory areas to be written to with data. The consequences of a buffer overflow can be … Read more
What is An Attack Vector? Attack vector refers to a specific way and/or technique to perform an attack on an IT system. Cybercriminals use attack vectors to compromise or take over foreign computers and systems. Often, the exploitation of one or more attack vectors takes place in multi-step manual or automated procedures. In the cyber … Read more
What is Diffie-Hellman key exchange? Diffie-Hellman key exchange is a method for securely agreeing on a shared session key between two communication partners over a potentially insecure transmission medium. The method is used for numerous cryptographic protocols on the Internet. In the world of secure communication and cryptography, the Diffie-Hellman Key Exchange is a fundamental … Read more
