Morris Worm: How a Simple Experiment Led to the First Computer Worm
Not so long ago, in 1988 to be exact, computer worms weren’t even a thought in a programmer’s[…]
RSA, a form of public-key cryptography widely used to secure communication between multiple parties was discovered in 1977 by Ron Rivest, Adi Shamir and Leonard Adleman. But they weren’t the only ones working on public-key encryption. Two Stanford technologists Whitfield Diffie and Martin E. Hellman introduced their own public-key cryptosystem just ahead of the RSA algorithm.
A new study from Exabeam reports that the majority of organizations see significant value in red/blue team testing — and are using lessons learned from the exercises to strengthen their cybersecurity programs. The survey also found that 74% of respondents have seen their companies increase investment in security infrastructure as a result of red and blue team testing.
For cybersecurity teams, getting in front of security threats is a top priority. But with so many potential threats and adversaries, putting in place appropriate threat detection can seem a daunting task. Breaking down threat detection and a response to the most basic elements can bring that clarity.
The first DEF CON was held in 1993 as a farewell party for founder Jeff Moss’s friend. The friend couldn’t make it and what started out as an almost-failed party plan turned into one of the biggest technology events held each year.
Advanced Encryption Standard (AES) is used by the US government to encrypt classified documents. AES brought 128-bit encryption to the market. Data can be encrypted in 128-, 192-, and 256-bit amounts, with the number of rounds used to protect data growing as the encryption level increases.
On April 16, 1993, the White House announced the Clipper chip to secure communication devices like crypto phones, which protect calls from interception by using algorithms and cryptographic keys to encrypt and decrypt the signals. Here’s what happened next.
