A brute force attack (exhaustive search) is a cryptographic hack that relies on guessing possible combinations of a targeted password until the correct password is discovered. This attack uses trial-and-error to guess login info, encryption keys, or find a hidden web page. Brute force attacks don’t employ an intellectual strategy. These attacks simply try using [...]

IT Security Baselines

All organizations are need to keep their apps and devices secure. These apps/ devices must be compliant with the security baselines defined by the organization. A security configuration checklist (lockdown or hardening guide or benchmark) is form a series of instructions for configuring a product to a particular security baseline. IT security checklists are helpful to [...]

IPsec Protocol

Internet Protocol Security (IPsec) is a secure network protocol suite that authenticates and encrypts the packets of data to provide secure encrypted communication between two computers/networks. IPsec is usually used to set up VPNs, and it works by encrypting IP packets, along with authenticating the source where the packets come from. Read more about encryption [...]

About Hashing And Its Applications

We have already mentioned hashing in some posts, for example, in this post. We want to talk more about hashing now. Hashing data is a common practice in computer science and is used for several different purposes. Hashing is the practice of taking a string or input key, a variable created for storing narrative data, [...]

Cryptography- Part 4 Hashing Hash functions are primarily used to provide integrity. Hashing and cryptography have a very close relationship. A one-way function ensures that the same key can’t encrypt and decrypt a message in an asymmetric key system. A one-way function’s purpose is to ensure confidentiality. A one-way hashing algorithm produces a hashing [...]
