Hashing is a cryptographic process that converts data of any size into a fixed-length string of characters, known as a hash value or hash code, using a mathematical algorithm called a hash function. This unique digital fingerprint represents the original data and is essential for verifying data ...
Though many people use the terms 'hashing' and 'encryption' interchangeably, hashing is a one-way function. This prevents the conversion of the hash back into the original key, which is necessary because that would defeat the purpose of hashing as a security measure. Because hashes are a one...
The cyberthreat hunter and the cyberthreat analyst use similar tools. The distinction between the two is that the cyberthreat hunter is the aggressor, discovering and destroying malicious code before it activates, while the cyberattack analyst is in a more neutral, even defensive role, using threa...
Security What is a cyberattack? A cyberattack is any intentional effort to steal, expose, alter, disable, or destroy data, applications, or other assets through unauthorized access to a network, computer system or digital device. Threat actors start cyberattacks for all sorts of reasons, from...
Cyber Security refers to the practice of reducing cyber risk through the protection of the information technology (IT) infrastructure.
Pass the hash is a type of cybersecurity attack in which an adversary steals a “hashed” user credential and uses it to create a new user session on the same network.
Hashing is relevant to but not limited to data indexing and retrieval, digital signatures, cybersecurity, andcryptography. When someone creates and encrypts a digital signature with a private key, hash data is also created and encrypted. The signer's public key then enables the recipient to decr...
For example, a Bitcoin Sybil attack can be used to obtain information about the IP address of a user connecting to the network. This compromises the security, privacy and anonymity of web users. The only thing an attacker has to do is take control of nodes in the network, gather ...
A pass-the-hash attack is one of the approaches that is utilized on a regular basis for the purpose of acquiring these capabilities. 🔍
What's the role of a cipher in secure sockets layer (SSL) and transport layer security (TLS)? In SSL and its successor TLS, a cipher suite is used to secure data transmission over a network. The cipher suite specifies the encryption algorithm (cipher) to be used, along with other compon...
